What is the shutdown sequence for automatic transmission vehicles?

[Jade]

Automatic transmission vehicle shutdown sequence is as follows: straighten the steering wheel, turn off all electrical equipment including all windows and sunroof, press the brake pedal, shift to N gear, engage the handbrake, shift to P gear, release the brake pedal, and turn the key to shut off the engine. One important thing to remember is that whether shutting down in P gear or N gear, always tighten the handbrake before releasing the foot brake. Only the handbrake can truly prevent the vehicle from moving, as the P gear functions similarly to engaging first gear in manual transmission vehicles to prevent rolling. If the handbrake is not engaged, the vehicle may move downhill under gravity and inertia, which could damage the transmission if only P gear is engaged. Over time, this can significantly shorten the transmission's lifespan, so always engage the handbrake first when parking.
