6 Causes of Sudden Car Engine Shutdown

Advanced driver assistance systems (ADAS) are a set of sensors, cameras and software that monitor the area around the car, warning you of a potential hazard or intervening in specific conditions by braking, steering or adjusting speed. Before buying, it is not enough to see a system's name in the specification sheet; ask exactly what it does, when it stops working and how to try it safely.

What are ADAS driver assistance systems and how do they work?

These systems usually rely on a camera behind the windscreen near the rear-view mirror, a radar behind the grille or front bumper, radars in the corners of the rear bumper, plus parking sensors and cameras around the body. The car's computer combines their signals to estimate distances, speeds and the car's position between the lane markings.

They differ from the anti-lock braking system (ABS) and the traction control system (TCS); those two monitor the wheels themselves, while ADAS monitors the road, vehicles and pedestrians around you, and many of these systems use the same brake system when they intervene.

What is the difference between warning and intervention systems?

The US National Highway Traffic Safety Administration (NHTSA) explains in its guide to driver assistance technologies that some systems are designed only to warn you, while others take action to avoid a crash, and that manufacturers use different trade names for the same function; so rely on the function described in the owner's manual rather than the name.

Having a warning system does not mean a matching intervention is fitted; a trim may include blind spot warning without any steering or braking intervention, so ask for the system list for the exact trim and model year you will buy.

How does automatic emergency braking work and what are its limits?

The NHTSA page on active braking technologies explains that these systems use radar, cameras and other sensors to detect vehicles, pedestrians or objects in front of the car, increasing braking force if your braking is insufficient, or braking automatically if you do not respond to the warning, with the aim of avoiding a collision or reducing its severity. This does not mean they prevent every collision in all conditions.

Ask when buying: does the system detect pedestrians and cyclists, or only vehicles? Does it work when reversing? And what speed range does it operate in according to the owner's manual? Never test it by deliberately approaching a car, a person or an obstacle.

What is the difference between lane departure warning and lane keeping assist?

The warning system only gives a sound or a vibration in the steering wheel when the car drifts across the lane markings, while the assist system gently corrects the steering, and in some cars may brake one of the wheels. Lane centring, by contrast, steers the car continuously while it is active, and usually works together with adaptive cruise control.

These systems depend on the camera seeing the road markings, so their performance weakens when the lines are faded or missing, as on some desert roads and in diversion zones, and many cars alert you if you take your hands off the wheel while they are active.

How does adaptive cruise control differ from standard cruise control?

Standard cruise control keeps a fixed speed that you set, whereas the adaptive version slows down if you approach a slower vehicle, then returns to the set speed when the road clears, and in some cars it can stop and move off again in traffic.

Before using it, learn how to choose the following distance and how to cancel it with the brake pedal or the cancel button. Its braking ability is limited, and it may not respond as you expect to a stationary vehicle or a car that cuts in suddenly; so stay ready to brake yourself.

What are the benefits of blind spot monitoring, rear cross traffic warning and the surround-view camera?

Blind spot monitoring alerts you with a light in the side mirror, some systems add a sound if you signal towards a lane with a vehicle in it. Rear cross traffic warning is useful when reversing out of a parking space between large vehicles that block your view.

The surround-view camera shows a combined image as if you were seeing the car from above, but it can distort distances at its edges and does not replace the mirrors and turning to look yourself.

How do you check ADAS features during a test drive?

Alongside the general steps in our new car buying guide, set aside part of the test drive for the assistance systems:

1. Before moving off, get to know the settings menu and each system's symbols on the instrument cluster: ready, active and unavailable.
2. On a highway with clear markings, switch on adaptive cruise control and set the distance, then cancel it with the brakes and with the button.
3. Notice the lane departure alert, whether it stays quiet when you use the turn signal, and whether the correction is smooth or intrusive.
4. Watch the blind spot signal when a car passes alongside you, without relying on it to change lanes.
5. In a car park, reverse slowly and check how clear the camera is and how the rear cross traffic alert works.
6. Make sure no persistent fault message appears, and that the windscreen and bumpers around the sensors are undamaged.

What conditions limit how sensors and cameras work?

• Dust, sand, mud and insects covering the camera, the radar or the bumper sensors.
• Sandstorms, fog and heavy rain.
• Low sun at sunrise and sunset, and glare from oncoming headlights.
• Extreme heat after long parking in the sun; some owner's manuals state that the function may stop temporarily until the camera cools down.
• Stickers, tint films and non-original accessories in front of the camera or radar.

If a message says the system is unavailable, continue driving carefully without relying on it, clean the sensors with water and a soft cloth while keeping high-pressure water away from them, and if the message persists, have the car inspected.

When do ADAS sensors need calibration?

The camera and radar are mounted at a precise angle, and even a small change can make the system misjudge distance or lane position. That is why the manufacturer may require the sensors to be checked or calibrated in cases such as:

• Replacing the windscreen that the camera is mounted on.
• Repairing the bumper or the grille, or removing and refitting the radar.
• A minor collision, even if the damage looks superficial.
• A wheel alignment, a change in suspension height, or a change of tyre size.

Before any repair, ask the service centre about the calibration requirements for your car, and ask for proof that it was carried out. With a used car, ask whether the windscreen has been replaced or the bumper repaired, and whether the sensors were calibrated afterwards.

Do driver assistance systems replace the driver's attention?

No. NHTSA's classification in the guide mentioned above makes clear that the driver remains responsible for driving and attentive at all times, even with systems that combine speed control and steering. Even driver attention monitoring is a reminder to stop and rest, not a substitute for rest; if you feel drowsy on a long journey between cities, stop in a safe place.

Frequently asked questions about driver assistance systems

1. Can ADAS be added to a car that does not have it? Add-on warning devices and cameras are available, but they are not equivalent to factory systems linked to the brakes and steering.
2. Can these systems be switched off? Many cars let you turn off some alerts or change their sensitivity, and some switch back on every time you start the car. It is best to keep them on.
3. Does windscreen tint affect the camera? Any film or sticker covering the camera area may affect its view, so leave that area clear.
4. Do assistance systems differ between trims of the same model? Usually yes; a higher trim may include systems that the base trim lacks.
5. Do these systems work just as well at night? Camera performance may suffer on dark roads, while radar does not depend on light.

Driver assistance systems add a useful layer of protection when you understand what each system does and its limits, and keep the sensors clean and calibrated after any repair. When browsing the cars listed by Saleh Cars Group, compare the assistance systems in each trim and ask how they work before you decide, because the final decision on the road always remains yours.

If you are asking when to replace car tyres, the short answer is: replace a tyre when the surface of the tread reaches the level of the raised wear indicators inside the grooves, when a bulge, a deep cut or clear cracks appear in its sidewall, or when the rubber has aged to the point at which the tyre or car manufacturer recommends replacement, even if the tread looks good. In this guide we explain how to check your tyres, what the wear pattern reveals, and how to choose the right replacement.

When should you replace car tyres? The key signs in brief

Replacement is not tied to a single distance for every car, but to the tyre's condition and its maker's recommendations. The main signs are:

• The tread surface has reached the level of the wear indicators in any part of the tyre, not just on average.
• A bulge or bubble in the sidewall, a deep cut, or exposed cords or internal fabric.
• Clear cracks in the sidewall or between the tread blocks, showing that the rubber has aged and hardened.
• Uneven wear that has left part of the tyre smooth even though the rest of its surface is sound.
• A persistent vibration that does not go away after balancing, or repeated pressure loss in the same tyre with no visible cause.

How do you check tread depth using the TWI wear indicators?

Inside the grooves are small raised bars called wear indicators, whose location is marked by the letters TWI or a small triangle on the tyre's shoulder, and when the tread surface is level with them, the tyre has reached the end of its usable life. To check:

1. Park the car on level ground and turn the steering wheel to one side so you can see the front tyres clearly.
2. Look for the TWI mark or triangle on the tyre's shoulder, then look into the groove next to it to find the raised bar.
3. Compare the level of the tread surface with the bar; the closer they are to level, the closer the replacement date.
4. Repeat the check on the inner edge, the centre and the outer edge, and at several points around the tyre's circumference.
5. For a more precise reading, use a tread depth gauge, available at tyre shops, and record the reading for each tyre.
6. Some drivers use a coin as a rough gauge, but it is no substitute for a proper gauge or a look by a qualified technician.

Do not wait until they are exactly level if you travel often or drive in the rain, as water clearance and grip weaken gradually as the tread gets shallower.

What do tyre cracks and sidewall bulges mean?

The sidewall flexes with every turn of the wheel and carries the car's weight, so any damage to it is more dangerous than tread wear:

• Fine surface cracks: an early sign of rubber ageing caused by heat and sun, which calls for the tyre to be inspected by a specialist and monitored.
• Deep cracks: if they widen or reach the tyre's inner layers, it is time to replace it.
• A bulge or bubble: damage to the tyre's internal structure, usually after hitting a pothole or kerb, which requires immediate replacement and no travelling on it.
• Cuts and gashes: a deep cut in the sidewall weakens the tyre even if no air is leaking from it yet.

What does the tyre wear pattern reveal?

The wear pattern reveals the cause of the problem, and if you do not fix it, new tyres will wear the same way:

If you see wear on both edges, start by reviewing the causes, signs and solutions for low tyre pressure, and if the wear is on one edge or comes with the car pulling to one side, read about the difference between wheel balancing and alignment.

How do Saudi heat and sand affect tyre life?

Rubber ages over time even if the car is used little, and you will find how to tell a tyre's age from the DOT code in our article on how to read tyre size and manufacture date. There is no single lifespan for all tyres, so refer to the tyre and car makers' recommendations. In the Kingdom's climate, some factors speed up deterioration:

• Direct sun and high heat speed up the hardening and cracking of rubber, especially for cars standing for long periods in open car parks, so park in the shade whenever possible.
• Hot asphalt raises tyre temperature, and the effect grows with low pressure or overloading on long trips.
• Sandy, gravel and desert tracks expose the tread and sidewall to cuts from sharp stones, so inspect the tyres after every desert trip.
• If you lower tyre pressure (deflating) to drive on sand, restore it to the recommended value before returning to asphalt, because highway driving at low pressure raises tyre temperature.

Should you replace tyres in pairs or all four together?

Ideally all four tyres match, but replacing them all together is not always necessary:

• Replace both tyres on the same axle together at least, so grip does not differ between the two sides when braking or cornering.
• When replacing only one pair, many tyre makers recommend fitting the newer pair on the rear axle for better stability, unless the owner's manual says otherwise.
• In four-wheel-drive or all-wheel-drive cars, the owner's manual may require the four tyres to be close in size and degree of wear to protect the drive system, so check it before replacing only two.

What about the spare tyre?

The spare forgotten in the boot ages just like the other tyres, even if it is never used:

• Check its pressure regularly and before every trip, because a flat spare will not help you when you get a puncture.
• Read its manufacture date and inspect its sidewall, as it may be older than the tyres on the car.
• A small temporary spare is designed for a limited distance and speed stated in the owner's manual or on the tyre's side, so use it only to reach the nearest tyre shop.
• If your car comes with a repair kit instead of a spare, check its expiry and how to use it.

How do you choose the right replacement tyre: size, load and speed?

Choose what your car was designed for, not just what the shop has in stock, and check the following:

1. Size: copy it from the sticker on the driver's door frame or from the owner's manual, not from the tyre currently fitted, which may be different.
2. Load index and speed symbol: choose values equal to or higher than the car manufacturer's recommendation, never lower.
3. Manufacture date: ask for recently made tyres with close dates, especially on the same axle.
4. Type of use: a driver who often travels on highways has different needs from one who drives in the desert or carries heavy loads, so ask about the tyre designed for your use.
5. Changing the size: do not change the size of your tyres or rims without consulting a specialist; to learn the effect, read our article on whether the wrong rims make your car use more fuel.
6. After fitting: balance the wheels, set the pressure according to the driver's door sticker, and check the alignment if the old tyres were worn unevenly.

What is the tyre energy efficiency label in Saudi Arabia?

The Saudi Standards, Metrology and Quality Organization offers the Energy Efficiency Label for Tires service, and explains that the label serves as a guide for consumers before purchasing the product to increase their awareness of its energy efficiency before buying it.

The organization lists tyres among the products subject to the efficiency label regulations, and the aims of these labels include reducing energy consumption for the consumer, enabling the consumer to know a product's efficiency before buying, and protecting consumer safety and health and the environment. In practice:

• When comparing tyres of the same size, ask to see the energy efficiency label for each one and read its details.
• Do not make the label your only criterion; size, load index, speed symbol, manufacture date and the tyre's suitability for your use come first.
• Requirements and procedures may be updated from time to time, so check the latest information on the organization's website.

Frequently asked questions about replacing car tyres

1. Should I replace a tyre that is old even if its tread is good? Tread depth alone is not enough, as rubber hardens over time; have it checked by a specialist and follow the tyre maker's recommendation.
2. Can a puncture in the side of the tyre be repaired? Repairing holes in the sidewall or shoulder is not usually recommended, while for a hole in the tread area the technician decides whether it can be repaired based on its size and position.
3. Can I fit two tyres of different types? This is not recommended on the same axle, and it is best for all four tyres to match in type and tread pattern, especially in four-wheel-drive cars.
4. Are small cracks between the tread blocks dangerous? They are a sign of ageing that may not require immediate replacement, but have a specialist monitor them, and if they deepen, replace the tyre.
5. How often should I check my tyres? Check their pressure and appearance regularly, for example when refuelling, before every trip, and after hitting a pothole or kerb or after a desert trip.

Checking your tyres takes only minutes: look at the wear indicators, inspect the sidewall, notice the wear pattern and read the manufacture date. If a danger sign appears, do not postpone the change; choose a replacement with the recommended size, load and speed ratings, then fix the cause of any uneven wear.

The difference between car trim levels is the difference in the equipment a manufacturer fits to the same model: the engine, transmission and drivetrain, safety and driver assistance systems, comfort and air conditioning, wheel and tyre size, and the screen and infotainment. Labels such as “standard” and “fully loaded” are not consistent between manufacturers, so a fair comparison depends on the official trim name, the model year and the written specification sheet. Here we explain where trims differ and how to compare them with a table, without paying for features you will not use.

What are car trim levels and why do their names vary?

A trim is a version of the same model with an equipment package set by the manufacturer; a model usually starts with a base trim, each higher trim adds a group of features, and trims may also differ in the engine or exterior styling.

• Standard, mid-spec and fully loaded are rough sales descriptions, and each manufacturer has official names for its trims.
• A fully loaded version of one model may lack a feature found on the mid-range trim of another, so never compare by the label alone.
• A trim's contents can change from one model year to the next and may differ by market, so a brochure from another country does not prove the car offered to you has the feature.

If you are at the start of the buying process, begin with our new car buying guide to set your budget and choose the type of car, then return to this article to compare trims in detail.

Do trims differ in engine, transmission and drivetrain?

On many models every trim shares the same engine, but some offer a larger, turbocharged or hybrid engine on higher trims. When the mechanical components differ, they matter more than any cosmetic extra, because they affect performance, fuel consumption and maintenance for as long as you own the car.

• Engine: record its size and type, and do not assume the larger engine suits you best if most of your trips are in the city.
• Transmission: the type may differ between trims, so read how a car transmission works and its main types before you compare.
• Drivetrain: two-wheel drive is usually enough in the city, while four-wheel drive helps if you head into the desert and sandy roads, but it adds weight and parts that need maintenance.
• Fuel consumption: it may differ between trims of the same model, so ask to see the fuel economy label for the version you are considering; the Saudi Standards, Metrology and Quality Organization explains that this label is a guide for consumers before purchase, to raise their awareness of energy efficiency.

How do safety and driver assistance systems differ between trims?

A phrase such as “comprehensive safety features” is not enough; ask for the names of the systems fitted to each trim and understand what each one does: does it only warn the driver, or does it intervene with braking or steering?

• Airbags: how many there are and where, plus child-seat anchor points if you travel with children.
• Forward collision warning only alerts you, while automatic emergency braking may apply the brakes if you do not react.
• Lane departure warning only warns, while lane keeping assist makes a limited steering correction.
• Blind spot monitoring and rear cross-traffic alert are useful on highways and when reversing out of busy parking spaces.
• Adaptive cruise control keeps a set distance from the car ahead and is comfortable on long trips between cities.
• A reversing camera and parking sensors, or a surround-view camera on some higher trims.

These systems assist the driver and do not replace attention, and dust on the sensors can affect how they work.

Which comfort and air conditioning features change from trim to trim?

Some comfort features help you every day in the Saudi climate, while others you may rarely use even though they raise the trim's price.

• Air conditioning: manual or automatic, single-zone or dual-zone, with or without vents for rear passengers.
• Seats: fabric or leather, manual or power adjustment, and ventilated seats that ease the summer heat.
• Keyless entry and push-button start, and a powered tailgate.
• A sunroof is appealing, but many drivers do not use it in summer, so weigh its value to you.

How do wheels and tyres affect comfort and running costs?

Higher trims often come with larger wheels and tyres with a lower sidewall, which gives a sportier look but does not necessarily mean more comfort.

• A lower sidewall usually absorbs bumps less, so the ride feels firmer on uneven roads.
• Check the spare: full-size, temporary, or a repair kit instead of a spare.
• Large or less common sizes may cost more to replace, so ask about the availability of the size on the trim you will buy.

Is the screen and infotainment worth paying for a higher trim?

A large screen is one of the most visible differences between trims, but its real value lies in how easy it is to use while driving.

• Test how quickly the screen responds and how clear it is in sunlight, and how easily you can reach the air conditioning settings without taking your eyes off the road.
• A digital instrument cluster, an upgraded sound system and wireless charging are pleasant extras, but not essential for every driver.
• Physical buttons for air conditioning and audio can be easier than touch control alone, so try both.

Does a higher trim hold its value at resale?

There is no fixed rule; resale value depends on market demand for the model and trim, and on the car's condition and service history.

• Expensive extras rarely recover their full cost, so do not buy a higher trim hoping to recoup the difference when you sell.
• Equipment that many buyers look for, such as a camera, sensors and safety systems, may make the car easier to sell.
• Browse used listings for the same model in different trims to gauge demand.

How do you compare car trims using a table?

Put the trims you are considering in one table and write against each item what is confirmed on the specification sheet, not what you heard or saw in an advert. Here is a template you can copy:

1. Classify each feature: essential and non-negotiable, desirable, or unimportant to you.
2. Rule out any trim that lacks even one essential feature.
3. Start with the lowest trim that covers all your essential needs.
4. Compare the price difference to the next trim only with the desirable features it adds.

How do you avoid paying for features you will not use?

The money you save on luxuries may be more useful for maintenance, insurance or a smaller finance amount.

• Do not be swayed by the display car: the car on show or the advertising photos may be of a higher trim, so ask to see and drive the trim that fits your budget.
• Watch out for packages: a feature you want may be bundled with features you do not need, so ask whether it is available on a lower trim or in a smaller package.
• Distinguish factory equipment from accessories fitted later, such as window tint, and ask who provides their warranty and what it covers.
• When buying with financing, the price difference between two trims becomes part of the finance amount and you carry its cost for the whole contract; read our comparison of buying a car with financing or cash before you decide.
• Ask about each feature: how often will I actually use it? If the answer is rarely, it is not reason enough to upgrade.

Frequently asked questions about car trim levels

Does fully loaded mean the same equipment on every car?

No. It is a sales description that varies from model to model and from year to year; ask for the official trim name and its detailed equipment list, and check every feature that matters to you.

Is the top trim of a smaller model better than the base trim of a larger model?

If space and seating are the priority, the larger model suits you better; if equipment matters more and the space is enough, the top trim of the smaller model may suit you.

Can higher-trim features be added after purchase?

Some accessories can be fitted later, but many driver assistance systems depend on factory sensors and software and are not easy to add, so ask how any modification affects the warranty.

Are videos and brochures enough for a comparison?

They help you understand the general idea and prepare your questions, but verify the specifications of the car offered to you, because the model year, market or trim may differ.

The right trim is neither the cheapest nor the most expensive; it is the lowest trim that covers your essential needs with written, confirmed specifications. Put the mechanical components and safety first, then the comfort you will use every day, and leave luxuries at the bottom of the list. When your table is ready, you can browse the cars available at Saleh Cars Group and compare their trims in the same way.

Car spare parts fall into three main types: genuine parts (dealer parts) that carry the carmaker's brand or are made by its supplier to the same specification, aftermarket parts made by other companies with varying quality, and used parts from salvage yards (tashleeh) removed from other cars, while counterfeit parts that imitate the look and brand of genuine parts should be avoided completely. The practical rule: choose genuine or trusted high-quality aftermarket parts for safety items such as brakes, steering, suspension, airbags and tyres, accept good aftermarket parts for consumables like filters, wipers and bulbs, and always confirm the part number, keep the invoice and have the part fitted at a qualified workshop.

What are the types of car spare parts and how do they differ?

Parts may look alike, but they differ in their maker, specification and source; the table below summarises the types found in shops and workshops:

The Technical Regulation for Auto Spare Parts issued by the Saudi Standards, Metrology and Quality Organization defines original parts as parts designed and manufactured to the vehicle manufacturer's specifications, made either by the vehicle manufacturer itself or by a manufacturer working to the same specification and quality control system, while commercial parts are replacement parts made to international standards, country-of-origin standards or the parts manufacturer's own standards, so that they meet the vehicle manufacturer's performance requirements.

Because market terms are not standardised, and some sellers use the word genuine or the abbreviation OEM for parts that do not come from the dealer, ask clearly: who made the part? What is its number? What warranty does it carry?

Which parts should be genuine or high quality?

Some parts are what stops the car, steers it or protects you in a crash, and they can fail suddenly. For these parts, do not make price the first criterion; choose genuine or an aftermarket part from a known manufacturer that meets the carmaker's specifications:

• Brakes: pads, discs and hoses; use brake fluid of the specification stated in the owner's manual, and you can review the types of brake fluid and the uses of each type.
• Steering: the steering rack, tie rods and their ends, since any play or breakage directly affects control of the car.
• Suspension: shock absorbers, control arms and ball joints, which affect the car's stability and grip; poor ones may wear quickly or break.
• Airbags and seat belts: do not buy them from an unknown source, and leave their inspection and replacement to a specialist technician.
• Tyres: buy them new from a trusted source in the size, load index and speed rating recommended for your car, and check their manufacture date.

The same applies to parts whose failure can cause major damage to the engine or gearbox, such as the timing belt, where fitted, and the water pump.

When are aftermarket parts a reasonable choice?

An aftermarket part is not necessarily poor, as quality varies from one manufacturer to another, and it is often a reasonable choice for consumables that are replaced periodically and are easy to check, such as:

• Oil, air and cabin filters: choose a filter that matches the size and specification, and learn the signs that your car needs a new air filter.
• Wipers and bulbs: check the wiper length and the bulb base type and wattage suitable for your car.
• Spark plugs: their type and specifications must match what the carmaker specifies, so read about spark plug types and when to replace them.
• Interior trim and plastic covers that do not affect safety.

In every case, insist on three things: a known manufacturer with clear data on the box, a part number that matches yours or is an approved replacement for it, and a seller who gives you an invoice. Because these parts follow fixed intervals, tie their purchase to your periodic car maintenance schedule instead of waiting until they fail.

Are used salvage parts a safe choice?

Salvage parts may be genuine originally, but they carry the age and usage of the car they came from, so they suit some cases and not others:

• Often suitable: exterior body parts such as fenders, mirrors and covers, cabin parts, and rare or discontinued parts, after confirming their condition and fit.
• Not suitable: wearing brake, steering and suspension parts, airbags and seat belts, tyres of unknown age, and filters and rubber parts.
• Engine or gearbox: do not buy either without a technical inspection; ask about its source and about a trial or return period, and record its number on the invoice.

Before buying, inspect the part yourself: signs of impact, welding or rust, signs of flooding or fire, or cracks in rubber and plastic, and match its number with your part's number.

How do you spot counterfeit spare parts?

A counterfeit copies the look, box and brand of the genuine part but not its specification, and may seem convincing at first glance. Warning signs include:

• The box: faded printing or unusual colours, spelling mistakes, a poorly made logo, a broken seal, or missing manufacturer name, country of manufacture and part number.
• The part itself: a rough finish, noticeably lighter weight than the old part, a missing engraved number and logo, or a different shape and mounting points.
• The price: a price far below the market for a part offered as genuine.
• The seller: a shop that gives no invoice, does not name the manufacturer and country of manufacture, or refuses returns if the part does not fit.
• Verification codes: if the box carries a verification code or security label from the manufacturer, check it through the manufacturer's official channels.

The same regulation requires each package to show the manufacturer's name or trademark, the country of origin, and the part's designation or number as classified in the manufacturer's catalogue; missing data is a warning sign in itself.

How do you confirm the part number before buying?

The part number is the most precise way to make sure a part fits your car, because parts for the same model can differ by model year, trim and engine type.

1. Photograph the part number engraved or labelled on the old part if it is visible.
2. Have the vehicle identification number (VIN) from your registration card ready, as it helps the dealer and shops identify the correct part.
3. Ask the dealer for the original part number, then compare any aftermarket alternative with it, as many aftermarket manufacturers list the original numbers their parts correspond to.
4. If you are told the part has a newer replacement number, ask for proof that it is an approved replacement for the old number.
5. Compare the new part with the old one before fitting: dimensions, mounting points and connections.

What should you ask of the seller and the workshop?

Proper paperwork and correct fitting matter as much as the part itself:

• A detailed invoice stating the part name, number and type (genuine, aftermarket or used), the country of manufacture, and any warranty and return terms.
• Old parts: ask the workshop to return them to you or show them to you, so you can confirm the replacement was actually made.
• Warranty: the seller's warranty on the part is different from the carmaker's warranty on the car; if your car is under warranty, read its terms or ask the dealer before fitting non-genuine parts or servicing elsewhere, and keep all invoices.
• A qualified workshop: brake, steering and suspension parts need the right tools and tightening torque, some require bleeding the brakes or a wheel alignment after fitting, and airbags need a specialist technician.
• After fitting: test the car with the technician, and make sure no warning lights appear on the dashboard and there are no strange noises.

Frequently asked questions about car spare parts

1. Are aftermarket parts always lower quality? No, their quality varies by manufacturer; some come close to genuine and some are poor. What matters is the manufacturer's reputation, matching the specification and the part number, not the word aftermarket alone.
2. Does fitting a non-genuine part void the car's warranty? It depends on your car's warranty terms, so do not assume the answer; check the warranty booklet or ask the dealer before fitting, and keep the part and workshop invoices.
3. Should I buy spare parts online? You can, from known stores that clearly state the manufacturer, the part number and the return policy, while being wary of very low prices for parts offered as genuine.
4. Can I fit an airbag from a salvage yard? We do not recommend it, because you know neither its history nor its condition, and it is one of the most important means of protection in a crash; ask for a new part suitable for your car, and leave fitting to a specialist technician.
5. What should I do if I discover a part is counterfeit? Stop using it if it is a safety part, keep it and the invoice, and go back to the seller. If you suspect commercial fraud, you can report it through the official channels of the Ministry of Commerce; procedures may be updated, so confirm the latest steps on its official platforms.

The difference between genuine, aftermarket and used parts lies in the specification, the source and the paperwork, not the name: choose the best for safety parts, use good aftermarket parts for consumables, treat salvage parts with caution, and avoid counterfeits completely.

To check traffic violations in Saudi Arabia, open the Query Traffic Violations page on the Absher platform and enter your ID number together with the violation number or your date of birth. To pay, sign in to the Efaa platform through the National Single Sign-On, choose the violations you want to pay, then pay through the SADAD system, a mada card or a credit card. To object, use the Dispute Traffic Violations service that the Ministry of Interior provides online. These procedures may be updated from time to time, so confirm the latest steps on the official platform before you act.

What are traffic violations and who issues them?

Traffic violations are violations related to the Traffic Law and its implementing regulations. As the description of the dispute service on the National Platform explains, they are issued by the General Department of Traffic or by any other authority authorised to apply the Traffic Law and its implementing regulations. In practice, you deal with them through three main services:

• Inquiry: to find out which violations are registered against you, through the Query Traffic Violations page on the Absher platform.
• Payment: through the Efaa platform, as part of a Ministry of Finance service for paying government violations registered against individuals.
• Dispute: through the Dispute Traffic Violations service provided by the Ministry of Interior, if you have something showing that the violation is incorrect.

It helps to distinguish traffic violations from other government violations, such as Ministry of Transport violations or municipal violations, because each authority has its own services; you will find a summary in the table below.

How do you check traffic violations on Absher?

The Absher platform provides a dedicated page called Query Traffic Violations, which asks for specific search details. The steps usually go as follows:

1. Open the Query Traffic Violations page from the official Absher website.
2. Enter your ID number in its field.
3. Choose the search type: by violation number or by date of birth.
4. Enter the violation number or the date of birth, depending on the type you chose.
5. Complete the verification code shown on the page, then display the result.

If you want to see the violations registered against you by different government entities in one place, the Efaa platform steps start with signing in through the National Single Sign-On (Nafath) and then viewing the registered violations, which we explain in the next section.

How do you pay traffic violations through the Efaa platform?

The service for paying government violations registered against individuals enables citizens, residents and visitors to view and pay all the violations registered against them by government entities, including traffic, smoking, government fines and other violations. The service page on the National Platform lists the payment steps as follows:

1. Go to the Efaa platform.
2. Choose to sign in through the National Single Sign-On.
3. View the violations registered against you.
4. Select the violations you want to pay.
5. Continue to the electronic payment page.
6. Complete the payment through the SADAD system, a mada card or a credit card.

According to the service description, the platform aims to unify and simplify violation procedures through a single digital platform that the relevant entities are linked to, so violations are issued and managed centrally. The National Platform also states that the service itself is free, meaning there is no charge for using it; this does not mean the violation amount is waived.

How do you dispute a traffic violation?

The Dispute Traffic Violations service provided by the Ministry of Interior allows you to dispute traffic violations issued by the General Department of Traffic and any other authority authorised to apply the Traffic Law and its implementing regulations. The service is provided online through the web portal and the mobile apps, and its path as shown on the service page is:

1. Go to My Services.
2. Choose Traffic.
3. Choose Dispute Traffic Violations, then follow the instructions shown to complete the request.

We have not listed deadlines or detailed conditions for disputes here because they do not appear in the service description on the National Platform; read the conditions and instructions shown to you inside the service before submitting, and do not delay your dispute if you believe the violation is incorrect. Before you start, the following helps:

• Make sure the violation really concerns your vehicle or your licence, and that its details match what happened.
• Write the reason for your dispute clearly and briefly, stating facts rather than impressions.
• If you have documents that support your position, prepare them in advance, and provide the details the service asks for.
• Keep proof that you submitted the request until you receive the decision.

What is the difference between violation services on the official platforms?

Several entities register violations, and each service has a specific purpose. The table below summarises the services listed in the official sources we relied on:

If a violation is registered with an entity other than the traffic department, look for that entity's inquiry service on the National Platform; for example, the Ministry of Transport and Logistic Services offers an inquiry through its web portal via the Ministry Services link and then the Violations Inquiry service in the list of inquiry services.

What are the most common causes of traffic violations you can avoid?

The best way to deal with violations is not to commit them in the first place, and most of their common causes can be avoided with simple habits that protect you and others on the road:

• Exceeding the speed limit: watch the road signs, because the limit changes between highways, inner streets and school areas, and cruise control helps you hold a steady speed on long roads.
• Not wearing a seat belt: make it a habit before moving off, for you and all passengers, however short the trip.
• Using the phone while driving: set navigation and calls before moving off, and leave messages until you stop in a safe, permitted place.
• Expired documents: track the expiry dates of your driving licence, the vehicle registration (istimara) and the insurance policy, and renew them before they are due.
• An expired periodic inspection: note its date in your phone calendar, and prepare the car beforehand with this checklist for preparing your car for the periodic inspection.
• Running a red light or stopping in prohibited places: slow down when approaching a signal, be ready to stop when it changes, and park only in permitted spaces.
• Neglecting the car's condition: make sure the lights and indicators work, and do not ignore warning lights; read about dashboard warning light meanings to know when to stop immediately.

Remember that driver assistance systems such as lane departure warning and adaptive cruise control help you, but they do not replace your attention, and they do not take over your responsibility to follow the rules.

What practical tips should you follow before paying or disputing?

• Check your violations regularly so they do not pile up without your knowledge.
• Read the details of each violation before deciding, then choose whether to pay it or dispute it.
• Reach the official platforms by typing their address yourself or through their official apps, and do not pay through links sent to you in messages from unknown sources.
• Do not share your verification code, login details or card details with anyone.
• Keep proof of payment until you are sure the violation status has been updated.
• If you face a technical problem, contact the entity that provides the service through its official channels.

Frequently asked questions about traffic violations

1. Do I need to visit a government office to settle a violation? Usually not; the inquiry, payment and dispute services mentioned are provided online through the official portals and apps, and the dispute service page shows a branches link for anyone who needs it.
2. Can I pay more than one violation at the same time? The Efaa platform steps include viewing the registered violations and then selecting the violations you want to pay before continuing to payment, so you decide what to pay.
3. Does the Efaa platform include non-traffic violations? Yes. The service description states that it covers traffic, smoking, government fines and other violations registered by government entities.
4. Can I dispute a traffic violation registered by an entity other than the traffic department? According to the service description, disputes cover traffic violations issued by the General Department of Traffic and any other authority authorised to apply the Traffic Law and its implementing regulations.
5. Who do I call if I face a problem? The service pages on the National Platform list the Ministry of Finance number 19990 for the payment service and the Ministry of Interior number 966114011111 for the dispute service, as well as each entity's official email address.

Dealing with traffic violations is easier than it looks: check them on Absher, pay them on the Efaa platform, dispute them through the Ministry of Interior service if you have a clear reason, and always review the updated steps on the official platforms. Most importantly, avoid their common causes from the start: keep to the speed limit, fasten your seat belt, keep your phone out of your hand, and renew your documents before they expire.

To get real value from a test drive before buying a car, ask to drive the same trim you plan to buy, and drive it on a route similar to your daily journeys: streets with speed bumps and traffic lights, a stretch of highway, and a place to park. Test the air conditioning, visibility, noise and family seating, and record your notes under the same items for every car. Budget, trims and the contract are covered in the new car buying guide.

How do you prepare for a test drive before visiting the showroom?

A successful test drive starts before you sit behind the wheel; good preparation makes you test what matters to you, not whatever catches your attention in the moment.

1. Write a short description of how you will use the car: city journeys, a daily highway commute, intercity travel, passengers in the rear seats, or a tight parking space at home.
2. Choose three priorities you will not compromise on, such as back comfort, easy parking and strong cooling, and make them the focus of your assessment.
3. Ask the showroom in advance whether the model, trim and engine you are considering are available to test, how long the drive lasts, which route is available and which documents are required, and bring your driving licence.
4. If the test car is a different trim, ask the team to explain the differences in engine, equipment, and wheel and tyre size, because they affect how the car feels and how much noise you hear.
5. If you are comparing two cars, try to drive both on the same day and at a similar time, so the heat, traffic and road conditions are alike.

What should you check before the car moves?

Set aside a few minutes before driving off; much of what will bother you in everyday use shows up while the car is standing still.

• Adjust the seat, steering wheel and mirrors, and check that you can reach the pedals comfortably without stretching your leg or sitting too close.
• Stay seated for several minutes and notice whether the seat supports your back and thighs, or whether you keep changing position.
• Make sure the instruments and the dashboard screen are readable in sunlight, and that the screen does not reflect on the windscreen.
• Look at the front pillars and side sightlines: do they hide pedestrians or cars at junctions?
• Pair your phone and set a navigation destination while parked, and try the air conditioning controls without looking at them for long.
• Before handing the car back, unpair your phone and delete your data from the infotainment system.

What is the right route for a test drive?

If the showroom's arrangements allow it, ask for a route that resembles your daily driving instead of circling the building, and always keep to the speed limit and the accompanying employee's instructions.

1. City streets with stop-and-go traffic: notice how smoothly the car moves off, how the transmission shifts and how the accelerator responds.
2. Speed bumps and uneven asphalt: listen to the suspension, and notice whether the cabin shakes uncomfortably or the car absorbs bumps quietly.
3. A roundabout or a series of bends: notice the steering weight and feel, and how much the car leans in corners.
4. A stretch of highway: notice the car's stability, how easily it merges with traffic and overtakes, and the level of wind and tyre noise.
5. A U-turn in a permitted place: it shows you how easy the car is to manoeuvre in narrow streets.
6. Brakes: press them gradually as in normal use, and do not create a hazardous situation to test the brakes or driver assistance systems.

How do you test the air conditioning in Saudi heat during the drive?

Air conditioning is one of the most important things to test in the Kingdom's climate, but a short drive only gives a first impression and cannot prove cooling performance in every condition.

• If possible, try the car after it has been parked in the sun, which is closer to your real use than a car pre-cooled inside the showroom.
• Run the air conditioning at the setting you normally use, and notice when the air from the vents becomes cool and comfortable.
• Notice whether cooling stays good when stopped in traffic or at a signal, not only while moving.
• Ask about rear air vents, and ask your companion to assess the airflow reaching the rear seats.
• Raise the fan speed and listen to it, as some cabins become noisy at high settings.
• When comparing two cars, test the air conditioning in similar heat and at a similar time; otherwise, note the difference next to your observations.

How do you assess noise, visibility and parking?

These items are hard to judge from a specification sheet, but they become clear on a real drive.

• Noise: talk to your companion in a normal voice on the highway, and notice whether you have to raise your voice because of the tyres, wind or engine.
• Unusual sounds: if you hear a knock, squeak or vibration, ask about it and note it rather than diagnosing it yourself or treating it as a trait of every car of that model.
• Rear visibility: notice the size of the rear window and how clear the mirrors are, and whether you need to turn your head a lot when changing lanes.
• Camera and sensors: assess how clear the camera image is in strong sunlight, and how clear the sensor alerts are when approaching obstacles.
• Parking: try reverse and parallel parking in a safe, permitted place, and notice how easy it is to judge the car's corners.
• If your parking space at home is tight or its entrance is sloped, compare the car's published length and width with your space before the visit.

How do you test family seating and luggage space?

If the car is for the family, the opinion of whoever sits in the back matters as much as yours.

1. Set the driver's seat to your position, then sit behind it and notice the room left for knees and head.
2. Ask a family member to try getting in and out through the rear door, especially older relatives.
3. If you have children, ask about the child seat anchor points (ISOFIX) and try fitting the seat with the showroom's agreement.
4. In cars with a third row, try reaching it and folding the seats, and notice how much boot space remains.
5. Put the pushchair or a suitcase in the boot, as written dimensions become clearer when compared with your own belongings.

How do you compare two cars after the test drive?

Write down your notes as soon as you step out of the car, before impressions get mixed up, and use a notes sheet with the same items for each car, like the table below:

Give each item a score from one to five with a short reason, and give your three priorities more weight than the rest.

• Do not judge by the total score alone; one car beating the other on an item you do not care about does not make up for weakness in a key priority.
• Record the test conditions: the time, the heat, the route and the trim you drove.
• If the two cars are close, ask for a second drive focused on the item that remains undecided.

What are the common mistakes on a test drive?

• Settling for a short loop around the showroom that does not resemble your daily driving.
• Driving a higher trim and assuming all its equipment comes with the trim you will buy.
• Getting distracted by conversation or the screen while driving instead of focusing on the road and the car.
• Comparing two cars driven in very different conditions without noting it.
• Deciding in the first rush of excitement before calmly reviewing your notes.

Frequently asked questions about test drives

1. How long should a test drive take? There is no fixed duration; what matters is that it is long enough for a route that resembles your use. A short drive may be enough to rule out a car, but it may not settle long-journey comfort.
2. Should I test a higher trim if I plan to buy the base trim? It can still be useful if you know the differences, so match the engine, equipment and wheel size to the trim you want before relying on your impressions.
3. Is a used car test drive different? Yes. In addition to the above, ask for the engine to be started cold, make sure the warning lights on the dashboard go out after starting, and do not rely on the drive alone; read our vehicle inspection tips before buying a used car.
4. Should I take someone with me on the drive? A companion can assess the rear seats and notice what you might miss, after checking the showroom's policy on passengers.
5. Do I have to decide on the same day? No. Review your notes once you are away from the showroom atmosphere, compare them with your priorities, then decide.

An organised test drive turns a general impression into information you can compare: prepare your priorities, choose a route that resembles your day, test the air conditioning, visibility, parking and family seats, and record everything under the same items. You can browse the cars available at Saleh Cars Group to compare models and trims, and contact the team to ask whether a test drive of the trim you are interested in is possible.
