As an Audi owner, my A8 uses 245/50 R18 tires, with the model number printed on the tire sidewall. In this series of numbers, 245 represents the width in millimeters, 50 indicates the aspect ratio, and 18 is the wheel diameter in inches. Choosing the correct size is crucial. For instance, I've experienced how good tires provide more stable handling and lower noise on highways. Different vehicle versions may have different tires, such as the sport version sometimes using 255/45 R19. I recommend checking the vehicle manual to confirm the specific model to avoid incorrect replacements, which could affect steering and safety. Personally, I check tire pressure and wear monthly to reduce sudden risks during high-speed driving. Remember to consult the 4S dealership for the most accurate advice, as they always keep records.

What is the purpose of engine start-stop?

Engine start-stop is achieved by equipping a traditional engine with an enhanced motor that has idle start-stop functionality, allowing the engine to completely shut down when the vehicle meets idle stop conditions. When the vehicle needs to move forward again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine, thereby reducing fuel consumption and exhaust emissions. For example, when the vehicle is stationary at a red light or in traffic congestion, the system can automatically stop the engine, while still allowing the use of in-car devices such as air conditioning and audio systems during the stop phase. This technology can save approximately 5% of fuel under normal driving conditions and around 15% in congested traffic.

What is the maintenance interval for the Toyota 86?

Toyota 86 requires a minor maintenance service at approximately every 5,000 kilometers driven and a major maintenance service at around every 10,000 kilometers, with minor and major services alternating thereafter. The specific maintenance schedule for the Toyota 86 can be found in the vehicle's user manual or by consulting staff at a Toyota 4S dealership. Below is relevant information: 1. Generally, a car's maintenance interval is not fixed. If the vehicle is used infrequently, the maintenance interval can be extended to every 7,000-10,000 kilometers. For older vehicles, the maintenance interval should be shortened, with service recommended approximately every 3,000 kilometers. 2. During maintenance, the most routine procedure is changing the engine oil and oil filter. Typically, new cars can use lower-viscosity oil, while older vehicles require higher-viscosity oil. When changing the oil, it is essential to use the same brand and type of oil. Mixing different oils can affect the engine's normal operation and, in severe cases, may lead to engine failure. 3. As a sports car, the Toyota 86 is generally not used as frequently, but it is prone to aggressive driving. Therefore, it is advisable to perform maintenance approximately every 5,000 kilometers.

What is the reason for oil spraying from the engine exhaust pipe?

Engine exhaust pipe oil spraying is caused by a damaged car valve oil seal, and the solution is to go to a repair shop to replace the oil seal. The car exhaust pipe, also known as the car exhaust pipe hose, is installed between the engine exhaust manifold and the muffler, allowing the entire exhaust system to have a flexible connection. This helps in reducing vibration and noise, facilitates installation, and extends the life of the exhaust muffler system. The engine exhaust pipe is mainly used in light vehicles, micro vehicles, and buses. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings on both ends. To achieve optimal noise reduction, the corrugated pipe can be equipped with an expansion joint or mesh sleeve inside.

What is the working principle of the brake light switch?

The working principle of the brake light switch is that when the driver steps on the brake pedal, it presses down on the contact point of the brake light switch, thereby completing the brake light circuit and illuminating the brake light. When the brake pedal is released, the contact point of the brake light switch disconnects, turning off the brake light. The brake lights are usually installed at the rear of the vehicle, with the main brake light being red. The red color enhances the light's penetration, making it easier for following vehicles to discern the driving status. Since the brake light switch is a signal transmission switch, when the brake pedal is pressed, the brake light switch closes and simultaneously sends a level signal to the ECU. The ECU then processes this signal based on its frequency and sends a command to the ABS/EBD system, which determines whether to activate accordingly.
