Stopping the engine
The ignition switch should be turned off only when the vehicle is stopped and the engine is idling.

Do not stop the engine when the vehicle is moving. This will cause loss of power to the power steering and the brake booster, making steering and braking more difficult. It could also result in accidental activation of the “LOCK” position on the ignition switch, causing the steering wheel to lock.
