What are the steps to remove the key from an automatic transmission car?

[AdamAnn]

Depress the car's brake pedal to slow down the vehicle. Park the vehicle on a safe road surface. Shift the car's gear lever to the P (Park) position. Pull up the car's electronic parking brake switch. Turn the car key to the OFF position to shut off the engine, then the key can be removed.

When I have an automatic transmission car, pulling out the key is actually quite simple: first, make sure the car is parked steadily, the gear is in P (Park), and then after turning off the engine, twist the key to pull it out. If you don't shift to P, the key won't turn—that's a safety design to prevent rolling. Every time I park, I've developed the habit of checking the gear to avoid accidents. Once, I was in a hurry to get out and forgot to shift to P, causing the car to roll slightly a few centimeters and almost hit something. Since then, I've been more careful with my actions. Some modern cars have additional buttons to press, but the core is confirming the P gear. Practicing more to form an instinctive reaction reduces risks.
