What is the function of the P gear in an automatic transmission car?

The function of the P gear in an automatic transmission car is to lock the vehicle's braking device, preventing the vehicle from moving. The method to start an automatic transmission car is as follows: 1. Start the car with the gear in N or P position; 2. After starting the engine, wait a few seconds before shifting gears to allow the transmission to be fully lubricated. Press the brake pedal, shift to the correct gear, release the brake pedal, and the car will start normally; 3. When driving on the road, place the gear shift lever in the D position and gradually increase the throttle; 4. When driving on short and small slopes, place the lever in D or L position and control the throttle to complete the uphill; 5. When driving downhill, use the D gear in combination with the brake to control the vehicle; 6. When driving on snow, place the lever in L position, start with L gear to prevent the drive wheels from slipping, and then shift to D gear after the car starts moving.

How to Adjust the Rearview Mirrors of a Citroën Sedan?

Adjusting the rearview mirrors of a Citroën sedan depends on different situations: 1. Adjusting the left rearview mirror: For up and down positions, place the distant horizon in the center; for left and right positions, adjust until the car body occupies one-fourth of the mirror's surface. 2. Adjusting the right rearview mirror: Position the horizon at two-thirds of the mirror's height, then adjust the car's edge to occupy one-fourth of the mirror's image. 3. Adjusting the interior rearview mirror: Ensure you can see through the rear window, with the upper and lower spaces adjusted so that the sky and ground each occupy about half of the view.
