For many motorists, stopping and turning off the engine is a routine operation. However, during operation, some drivers may wonder: should they engage P gear or turn off the ignition first?
In fact, the correct sequence of operation should be to put on the P gear first, and then turn off the ignition. Below I will explain why it is the right thing to do.
First of all, the P gear can ensure that the vehicle is stationary. When we park, the vehicle needs to be in a stable state to prevent any accidental sliding or moving. Hanging the P gear locks the propeller shaft so that the vehicle cannot move forward or backward, thus maintaining the stability of the vehicle.
Secondly, the P-gear can protect the transmission. If we stall without a P gear, the transmission may experience unnecessary stress and damage. When we start the vehicle, if there is no P gear, the vehicle will not be able to move because the driveshaft is locked, which can lead to damage to the mechanical parts inside the transmission.
Finally, the P-gear can also provide additional security. In some cases, such as when parking on a ramp, the vehicle may slide or roll due to gravity if there is no P gear. This can cause damage not only to the vehicle but also to the surrounding people and property.
To sum up, the correct sequence of operation is to hang the P gear first, and then turn off the ignition. This ensures vehicle stability, protects the transmission, and provides additional safety. Therefore, whether it is parking in a parking lot or on the road, we should always follow this sequence to operate our car automatics correctly.
