1 Answers
Car automatic transmission letters refer to: 1. P stands for Park, the gear lever needs to be shifted into P when the car is parked; 2. R stands for Reverse; 3. N stands for Neutral, used when starting, parking without leaving the car, or during towing; 4. D stands for Drive, place the gear lever in D when driving; 5. S stands for Sport mode. The method to use an automatic transmission car is: 1. Press the brake and push the start-stop button to start the engine; 2. Shift the gear to D, release the handbrake, and then release the brake. The working principle of an automatic transmission is to use planetary gear mechanisms for shifting, automatically changing gears based on the degree of the accelerator pedal and changes in vehicle speed.
