What does the 'A' with a circle icon in a car mean?

The 'A' with a circle icon in a car represents the Auto-Hold system function. The Auto-Hold system (AUTO-HOLD) is a technological application that enables automatic handbrake functionality while the car is in operation. This technology allows drivers to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. The functions of the Auto-Hold system include: 1. During driving, when encountering situations like a red light that require a brief stop, the system will automatically brake the wheels after the vehicle comes to a complete stop to prevent rolling. 2. When starting on an uphill slope, the system will automatically brake to prevent backward sliding. Once the forward traction reaches a level sufficient to move uphill, the system will release the wheels automatically, allowing the vehicle to proceed forward. 3. When parking and locking the car, there is no need to pull the handbrake as the system will automatically brake the wheels. However, this feature is not available in some car models, and manual handbrake operation is still required when parking.

What does 'snow' mean on a car?

'Snow' refers to the snow mode of a car, which can be activated when driving on snowy or slippery roads. How to use it: Push the gear lever to the D position and adjust the knob to snow mode. At this time, the front and rear torque will be distributed in a 40:60 ratio, which can improve the vehicle's grip through power distribution and enhance driving safety on snowy roads. Typically, many cars are equipped with both 'sport mode' and 'snow mode' options. You can choose the appropriate driving mode based on environmental requirements to meet the driver's needs for both fun and safety. Sport mode increases the engine's shift RPM to enhance power performance. Some automated settings allow the transmission to start in second gear, ensuring smoother and gentler torque output, thereby reducing the likelihood of tire slippage on icy surfaces. Additionally, during driving, the ABS system's operational range is expanded. Normally, ABS only engages when the brake pedal is pressed hard, but in snow mode, it activates even during non-emergency braking. All these measures are designed to ensure safer driving on icy or snowy roads. This feature is particularly practical for cities in colder northern regions.

What to Do When Vehicle Transmission Fails?

Here are the repair methods for automatic transmission failures: 1. Automatic transmission oil leakage. Repair method: If the sealing ring is aged, simply replace it. If the joint surface of the transmission case is damaged, thicken the paper gasket appropriately for repair. However, for severe leakage, welding repair is required. 2. Improper throttle cable or throttle position sensor. Repair method: The position needs to be readjusted. 3. Faulty speed sensor. Repair method: A new sensor needs to be replaced. 4. Engine idling. The transmission suddenly shifts from high gear to low gear, which is likely due to abnormalities in the control system or cooling system. Repair method: It needs to be handled by professionals.

How to Repair Scratches on Plastic Bumpers?

Here are the methods to repair scratches on plastic bumpers: 1. Toothpaste: When the bottom of the front bumper is scratched, using toothpaste is very effective because toothpaste itself has a polishing function, which is equivalent to applying a layer of wax to your car, thus achieving a good repair effect. However, toothpaste can only be used for minor scratches; it has little effect on deeper ones. 2. Paint Scratch Repair Agent: As the name suggests, the paint scratch repair agent is also used to repair bumper damage. In fact, it works on the same principle as toothpaste, with a polishing effect that can quickly repair the damaged part of the paint. Of course, this can only repair minor scratches. 3. Touch-up Paint Pen: Using a touch-up paint pen can cover up some small and shallow scratches, making them less noticeable. Although there is still a certain gap compared to the original factory paint (color difference exists), and the durability is certainly not comparable to the original factory paint, after all, the touch-up paint pen is only for local touch-ups, the overall effect is relatively good.

What to Do If Gasoline is Added to a Diesel Car?

If you realize that the wrong fuel has been added, the first thing to do is to assess the amount of fuel added. If only a small amount of gasoline has been added recently, you may not need to take any action. However, if a significant amount has been added, you should immediately go to a 4S shop to drain the gasoline and clean the engine and fuel system. Here are the consequences and solutions: 1. Since the ignition point of diesel is much higher than that of gasoline, the diesel car can still be started after adding gasoline, as the diesel engine can easily compress and ignite the gasoline. However, over time, abnormal idling and white smoke from the exhaust pipe may occur. 2. If you have been driving for a while before discovering the issue, regardless of whether the car can still be driven, you should stop immediately, call a tow truck to move the car to a 4S shop or repair shop, quickly drain all the gasoline from the fuel tank, and then perform necessary cleaning of the fuel tank, engine, and fuel system, as well as replace any damaged parts.

What to Do When It Rains Heavily After Car Tinting?

Rain after car tinting has no effect because the film is applied to the inside of the car. As long as you don't open the windows, the rain won't reach the film. Additionally, after the film is applied, you should not open the windows for 48 hours. Below are some precautions to take after tinting: 1. Do not open the side windows for 48 hours after tinting; 2. Do not use solutions containing alcohol or ammonia to clean the tinted film; 3. If there are bubbles, they must be addressed at the tinting shop within 24 hours—do not attempt to fix them yourself; 4. Avoid placing adhesive labels directly on the tinted film; 5. You can clean the film after 2-3 weeks using a lint-free towel or other soft materials—do not use stiff brushes or hard objects to avoid scratching the film; 6. After tinting, there may be fogging between the glass, which is normal and will disappear within 2-3 weeks.
