Should the foot brake be pressed when starting in P gear of an automatic transmission?
1 Answers
Yes. Below are the precautions for using the foot brake: 1. Correct usage of the foot brake: The foot brake is generally used for deceleration and for emergency braking in dangerous situations. When driving on an ordinary road, when decelerating or stopping in complex situations, the accelerator pedal should be released in advance, utilizing the engine's pulling force, and then the brake should be applied gradually to slow down or stop. 2. When driving on mud, ice, or snow: Safe combined braking should be noted. Due to the low coefficient of adhesion, reduced braking efficiency, and high probability of skidding, the vehicle should use the foot brake alone to lock the wheels. When a car descends a steep slope, continuous use of the brake causes it to heat up, leading to reduced braking force until the brake fails. Therefore, during a long descent, the car should be pre-positioned in a low gear, making full use of the engine's drag operation to control speed. 3. When a vehicle is submerged in water, the brake is prone to failure: When soaked, a layer of water film adheres to the friction surface, reducing the friction coefficient by 20-30%, significantly lowering braking efficiency. Therefore, after wading through water, the vehicle must reduce speed and use the brake continuously multiple times to allow the heat generated by friction to evaporate quickly, restoring normal braking performance.
