CAUTION
General precautions while driving
Driving under the influence: Never drive your vehicle when under the
influence of alcohol or drugs that have impaired your ability to operate
your vehicle. Alcohol and certain drugs delay reaction time, impair judg-
ment and reduce coordination, which could lead to an accident that could
result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that
other drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone
or reading can result in a collision with resulting death or serious injury to
you, your occupants or others.
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.
