P--Parking, parking gear. When you park without using, the gear is here, at this time the wheels are in a mechanical holding state, which can prevent skidding.?

R--Peverse gear, reverse gear. It is used when reversing.

N--None, neutral. Use this gear when stopping temporarily (e.g. at a red light). Note that this gear indicates neutral, and to prevent the vehicle from skidding on slopes, be sure to apply the brakes.?

D--Forward gear, also known as drive gear. Needless to say, it is when moving forward, use this gear.

2 (or S) - low-speed gear, when going up a very large slope, or when starting on a more inclined slope, you can use this gear to start forward. In principle, putting the gear here restricts the car's gears from automatically switching only in the lower gears (equivalent to the first and second gears of a manual car) to ensure that the car gets maximum forward momentum.?

L (or 1) - Low, low gear. When going downhill, or down a long slope, putting the gear here can limit the car's gear automatically only on the lowest gear (equivalent to the first gear of a manual car), which can make the car use the engine power for braking when going downhill, and the driver needn't step on the brakes for a long time to cause the brake pads to overheat and become dangerous.
