3. Turn the wrench
counterclockwise until the tire is
lowered to the ground and the cable
has slack. When turning the wrench,
make sure that it does not scuff the
kick plate.
4. Slide the tire rearward, lift one
side and remove the retainer from
the spare tire.
Changing the spare tire
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park).
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block the wheel that is
diagonally opposite (other end of the vehicle) to the tire being
changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
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.
Turn off the running boards (if equipped) before working under
the vehicle, jacking, or placing any object under the vehicle.
Never place your hand in the hinge assemblies. A moving running
board may cause injury.
