■ General precautions while driving
Driving under the  influence:  Never drive  your vehicle when  unde r  the  influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-

death or serious injury.
Defensive  driving: Always  drive  defensively. Anticipate  mistake s  that  other
drivers or pedestrians might make and be ready to avoid acciden ts.
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 serio us injury to you,
your occupants or others.

have or use the key.
Children  may  be  able  to  start  the  vehicle  or  shift  the  vehicle  into  neutral.

the  cigarette  lighter,  the  windows,  the  moon  roof,  or  other  fea tures  of  the
vehicle. In addition, heat build-up or extremely cold temperatu res inside the
