Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency.
If the vehicle must be shut off
in an emergency:
1. Brake using a firm and
steady pressure. Do not
pump the brakes
repeatedly. This may

requiring increased brake
pedal force.
2. Shift the vehicle to
N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop
