Should an automatic transmission car shift gears first or start the engine first?

An automatic transmission car must start the engine first before shifting into drive gear. Below is a detailed introduction to the gears: 1. P (Parking) gear: When parking and not in use, the gear is in this position, and the wheels are mechanically locked to prevent rolling. 2. R (Reverse) gear: Used for reversing. 3. N (Neutral) gear: Used for temporary stops (e.g., at a red light). This gear indicates neutral, and to prevent the vehicle from rolling on a slope, the brake must be pressed. 4. D (Drive) gear: Also known as the driving gear. Used for moving forward. 5. 2 (Second) gear: Used for starting on very steep slopes or when driving on a relatively steep incline. The principle is that shifting to this gear limits the car's automatic gear shifting to only low gears (equivalent to first and second gears in a manual transmission car), ensuring the car gains maximum forward momentum. 6. L (Low) gear: When going downhill or descending a long slope, shifting to this gear limits the car's automatic gear shifting to only the lowest gear (equivalent to first gear in a manual transmission car), allowing the car to use engine braking downhill, preventing the driver from having to press the brake for extended periods, which could overheat the brake pads and cause danger.
When driving an automatic transmission car, the correct procedure is to start the engine first and then shift gears—this is absolutely a crucial safety habit. Think about it: if you shift gears first and then start the engine, the car might suddenly move forward or backward as soon as the engine fires up, especially in a sloped garage, potentially crashing into a wall or other objects. I’ve seen many accidents caused by beginners neglecting this step. The right way is: after getting in the car, first press the brake pedal, then start the engine, and wait for the tachometer to stabilize and the engine to run smoothly before shifting to D or R gear. This prevents the vehicle from moving unexpectedly, avoiding harm to people or damage to the car. Forming this habit is simple—just spend an extra second paying attention to the sequence every time you drive, and it will significantly improve safety. Remember, driving is no joke; details determine overall risk. The engine requires a no-load state during startup, and shifting gears before ignition adds stress to the transmission, causing long-term damage to components. So, whether it’s sunny or rainy, this small change can bring big benefits.
