WARNING
■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 oper-
ate your vehicle. Alcohol and cer-
tain drugs delay reaction time,
impair judgment and reduce coor-
dination, 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. Any-
thing 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 ma y injure them-
selves by playing with the win-
dows, the electronic sunshade, or
other features of the vehicle. In
addition, heat build-up or
extremely cold temperatures
inside the vehicle can be fatal to
children.
