ABS on a car stands for Anti-lock Braking System. Its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding (with a slip ratio of around 20%), ensuring maximum traction between the wheels and the road surface. Reasons for the ABS light to illuminate include: 1. Faulty wheel speed sensor; 2. ABS circuit malfunction; 3. ABS pump or pressure control solenoid valve failure; 4. ABS computer malfunction. Solutions are: 1. Normally, the light turns on when the ignition is switched on or the engine is started, as the system enters a self-test procedure. The light will turn off after the test is completed; 2. Have a professional use a diagnostic tool to inspect and determine whether the issue lies with the tone ring, sensor, wiring, etc.

What type of fuel should be used for BYD Han?

BYD Han should use 92-octane gasoline. Correct method for selecting gasoline octane rating: Check the label inside the fuel filler cap. There is always a (recommended standard) sticker on the inner side of the car's fuel filler cap, which is the most accurate and scientific standard calculated by engineers based on comprehensive engine technical parameters. Importance of choosing the appropriate gasoline: Every vehicle's manual mentions a term called compression ratio. If a high-compression-ratio engine uses low-octane gasoline, it will result in incomplete combustion, severe engine vibration, reduced power output, component damage, increased fuel consumption, and poor driving performance. Conversely, if a low-compression-ratio engine uses high-octane gasoline, it will cause delayed combustion, meaning the auto-ignition point won't be reached even at maximum compression ratio, leading to incomplete combustion as well. This requires additional fuel injection to ensure power output, which not only provides no benefit to the engine but also increases fuel consumption.

What is the correct emergency posture for the driver in a frontal collision?

If an unavoidable frontal collision with an oncoming vehicle occurs and the impact is directly ahead, the driver should quickly move away from the steering wheel, take cover towards the passenger seat, and swiftly lift both legs. Below is more related information: Reasons: 1. Vehicle collisions happen instantaneously, and humans cannot react quickly enough to avoid them. During a frontal collision, due to inertia, even with seat belts, the body will move forward, and this inertial force cannot be controlled manually. 2. It is nearly impossible to avoid; only by straightening both legs can the forward tilt of the body be minimized as much as possible, thereby protecting the head (and, strictly speaking, the chest as well, since statistics show that some injuries result from the pressure of the lower edge of the steering wheel on the chest). 3. Literally, moving away from the steering wheel is just a concept because, based on accident summaries, most fatal factors in car crashes involve the driver's head hitting the edge of the steering wheel or the windshield. Therefore, to reduce fatality rates, drivers must be instructed to 'stay as far away from the steering wheel as possible.' 4. Only when there is sufficient space (or distance) between the driver and the steering wheel can the airbag function effectively.

How often should the coolant be replaced for a Haval H2?

Haval H2 engine coolant should be checked every 6 months and replaced every 24 months. Here are more details about the coolant: 1. Most family cars require coolant replacement every two years or 40,000 kilometers, but the specific replacement interval depends on the vehicle's usage and whether the coolant level is below the minimum mark (the normal coolant level should be between MIN and MAX; if it's too low, it should be topped up promptly to avoid affecting the engine's cooling efficiency). 2. Long-term failure to replace the coolant can lead to deterioration in its quality, reducing its anti-corrosion properties. This can damage components like the radiator and pipes and affect the boiling and freezing points, compromising the coolant's effectiveness. Do not wait until the coolant turns black before replacing it—blackened coolant indicates severe deterioration and significant scale buildup, which may have already damaged the pipes. During each maintenance check, use a freezing-point tester to measure the coolant's freezing point. If the freezing point is too high, it means the coolant has deteriorated and needs replacement. 3. Generally, coolant should be replaced every two years or around 60,000 kilometers. Coolant prevents freezing when the vehicle is not running, as it resides in the engine block. If the liquid turns into a solid, it expands, which can crack the engine block. Additionally, after the vehicle starts, the coolant helps cool the engine to prevent overheating and potential damage. It also plays a role in preventing rust and excessive scale buildup, which can clog the pipes.

What documents should I bring for the first car maintenance?

Items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle purchase invoice, to be taken to the designated first maintenance facility for the service. Important note: make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific time varying by vehicle, usually after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard loads and normal speeds as required by the vehicle. The timing of the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first serves as the standard. The first maintenance items include: oil change, oil filter replacement, air filter cleaning, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and inspecting tires for damage or bulges. Estimated time required: approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is the replacement of engine oil and the oil filter. When changing the oil, the oil filter must also be replaced. The selection of oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush and clean with detergent, dry them, and then put them back. There are many vent holes under the rubber mats on the floor of the driver's compartment. Water entering these areas will not dry naturally but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the existing antifreeze and add the same brand from the beginning. Different brands of antifreeze have significantly different chemical properties. Various functional additives may corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. Some people apply lubricant to bolts and nuts to prevent rust, but this poses a risk to safe driving. At high speeds, bolts and nuts can easily loosen or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starter of an EFI car differs from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.
