Important Safety Precautions
Additional Safety Cautions
CAUTION
Drinking and driving is very
dangerous. Your reflexes,
perceptions, attentiveness and
judgment can be affected by
even a small amount of alcohol.
You can have a serious, or even
fatal collision if you drive after
drinking. Please don't drink and
drive or ride with a driver who
has been drinking. Ride home
in a cab or designate a driver
who will not drink.

CAUTION
(Continued)
Medical research shows that
alcohol in a person's system can
make crash injuries worse. This
is especially true of injuries to
the brain, spinal cord or heart.
This means that when any
person who has been drinking -
whether a driver or a passenger
- is in a crash, that person's
chance of being killed or
permanently disabled is higher
than if the person had not been
drinking.
CAUTION
Unlocked doors can be danger-
ous. Make sure to lock all doors
while riding in the vehicle.
Turn the cruise control switch
off when you are not using it.
