CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment 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 dis-
tracts 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 cigarette lighter, the windows, the moon roof, or other features of the
vehicle. In addition, heat build-up or ex tremely cold temperatures inside the
vehicle can be fatal to children.
