Should an automatic transmission car be started in P or N gear?

[DelMariana]

For automatic transmission cars, the engine can be started in either P (Park) or N (Neutral) gear. For safety reasons, modern vehicles require two conditions to be met during startup: first, the brake pedal must be depressed to start the engine, and second, the P or N gear startup principle must be followed. Therefore, if the brake is not pressed, the car will not start even when in P or N gear. Here are some relevant details about car gears: 1. When making a short stop without turning off the engine, you can shift to N gear. When parking and turning off the engine, you should shift to P gear. 2. While driving, avoid coasting in N gear, as this can affect the cooling and lubrication of the automatic transmission. 3. Before shifting to P gear, ensure the car has come to a complete stop to avoid damaging the transmission. At a red light, if the car has an autohold function, you can leave it in D (Drive) gear without any action. If the car lacks autohold, you can shift to N gear, but it is not recommended to shift to P gear while waiting at a red light.
