What is the correct shutdown sequence for an automatic transmission vehicle?
2 Answers
The correct shutdown and parking sequence is as follows: 1. Straighten the steering wheel. 2. Turn off all electrical equipment in the vehicle, including all windows, sunroof, etc. 3. Press the brake pedal and shift the gear to N (Neutral). 4. Engage the handbrake, shift to P (Park), release the brake pedal, and turn the key to shut off the engine. Whether shutting down in P or N gear, always engage the handbrake firmly before releasing the foot brake. Only the handbrake can truly prevent the vehicle from moving. The P gear functions similarly to engaging first gear in a manual transmission to prevent rolling. If parking on a slope, first shift to N, then press the brake, engage the handbrake, wait for the vehicle to stabilize, shift to P, release the foot brake, and finally turn off the engine. If P gear is engaged first, it means the P gear is acting as the brake, and the handbrake's braking effect is essentially ineffective.
When I used to drive an automatic transmission car, I always followed a careful shutdown sequence: first, come to a complete stop and keep the brake pedal firmly pressed, then shift to the P position, which is crucial for locking the transmission; next, engage the handbrake to ensure the car doesn’t roll, and finally, gently turn the key or press the button to turn off the engine. The whole process should be steady—don’t rush to release the brake, or the car might jerk and damage components. I’ve maintained this habit for years and found that it not only extends the transmission’s lifespan but also prevents dangerous situations like rolling on slopes. By the way, many modern cars now have electronic parking brakes, making the operation simpler, but the sequence remains the same. Always remember to check that the windows are closed after shutting down—anti-theft measures are important. Once you develop this habit, driving becomes more worry-free and safer.
