WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the ignition switch or related
parts. Unexpected and sudden
vehicle movement can occur.
• NEVER reach through the steering
wheel for the ignition switch, or any
other control, while the vehicle is in
motion. The presence of your hand
or arm in this area may cause a loss
of vehicle control resulting in an
accident.
OAE056172L
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 button 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.
