WARNING
To reduce the risk of SERIOUS INJURY or DEATH, take the following precautions:
Whenever the front door is opened, the ignition switch will illuminate, provided the ignition switch is not in the ON position. The light will go off immediately when the ignition switch is turned on or go off after about 30 seconds when the door is closed. (if equipped)
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 1st gear (for manual transmission vehicle) or P (Park, for Intelligent Variable Transmission (IVT)/dual clutch transmission vehicle) position, apply the parking brake, and turn the ignition switch to the LOCK position.
Unexpected vehicle movement may occur if these precautions are not followed.
NOTICE
Never use aftermarket keyhole covers.This may generate start-up failure due to communication failure
