WARNING
NEVER turn the ignition switch to the LOCK or ACC position while the vehicle is in motion except in an emergency. This will result in the engine turning off and loss of power assist for the steering and brake systems. This may lead to loss of directional control and braking function, which could cause an accident.
Before leaving the driver’s seat, always make sure the shift lever is in P (Park) position, apply the parking brake, and turn ignition switch to the LOCK position.
Unexpected vehicle movement may occur if these precautions are not followed.
