CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the surround-

may also lunge forward or lunge back suddenly as it becomes free. Use extreme
caution.

This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.

If your vehicle has to be stopped in an emergency
CAUTION
■If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal
harder to depress and the steering wheel heavier to turn. Decelerate as much as
possible before turning off the engine.
Only in an emergency, such as if it becomes impossible to stop the vehicle
in the normal way, stop the vehicle using the following procedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.

cle speed as much as possible.

hold the “ENGINE START
STOP” switch for 3 consecutive
seconds or more, or press it

cession.
