When the service brake of a motor vehicle suddenly fails during high-speed driving, the driver should take the following braking measures: quickly shift to a lower gear to reduce speed and use the parking brake to assist in deceleration, but the parking brake should not be pulled tight all at once. Here is some relevant information: 1. Brakes: Brakes are used to stop the vehicle. Brakes are divided into service brakes (foot brake) and parking brakes (hand brake). 2. Use of brakes: During driving, the service brake (foot brake) is generally used to slow down or stop the vehicle while moving forward. It is not only used to keep the vehicle stationary. The parking brake is used only when the service brake fails. Once the vehicle comes to a complete stop, the parking brake (hand brake) should be applied to prevent the vehicle from sliding forward or rolling backward.

To prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when parking in cold winter. The steps to replace antifreeze are: 1. Open the engine hood of the vehicle, and the antifreeze reservoir can be seen in the upper right corner; 2. Open the antifreeze plug under the radiator to drain the old antifreeze; 3. Add new antifreeze, tighten the cap, and the antifreeze replacement is completed.

What does the car REST button mean?

Car REST button is the residual heat function of the car. It is called residual heat function because after the car is turned off for a period of time, you can still turn on the heating air conditioning through this button.

The car REST button is particularly suitable for use when parking and turning off the engine for a short time in winter. It can keep the temperature inside the car and avoid a rapid drop in temperature.

When starting, just press the REST button on the center console after the vehicle is turned off.
