WARNING: If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING: Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
1. Remove the spare tire and jack by
turning their tie-down bolts
counterclockwise. The lug wrench is
located in a bag next to, or on top
of, the spare tire.
2. Block the diagonally opposite
wheel.
3. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
