CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged if the spare tire is
mounted incorrectly.NOTE:
Do not install the wheel cover on the spare
tire.
7. Lower the vehicle by turning the jack screw to the left.
8. Refer to “Wheel And Tire Torque Specifi- cations” in “Technical Specifications” for
proper wheel lug bolt torque.
9. Lower the jack to its fully-closed position.
10. Stow the damaged wheel/spare tire with the cable and wheel spacer before driv-
ing the vehicle.
11. Install the winch extension and rotate the
wrench handle clockwise until the winch
mechanism operator hears “3 clicks” from
the device to indicate the wheel is properly
stowed under the vehicle. 12. Stow the jack, jack handle and winch
handle tools back in the storage
compartment.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
13. Check the spare tire pressure as soon as possible. Correct the tire pressure, as
required.
For vehicles with aluminum wheels:
The center cap must be pushed out from the
rear to install the retainer and stow the tire.
Wheel Covers
CAUTION!
Use a back-and-forth motion to remove the
hub cap. Do not use a twisting motion when
removing the hub cap, damage to the hub
cap finish may occur.
The wheel covers on the vehicle are held in
place by the wheel lug bolts and can be
removed after the wheel lug bolts are taken
off.
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so
please follow the procedures in this section
carefully.
NOTE:
When using a portable battery booster pack,
follow the manufacturer’s operating instruc-
tions and precautions.

WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been re-
moved and reinstalled on the vehicle, the lug
nuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

**Use only your authorized dealer recom-
mended lug nuts/bolts and clean or remove
any dirt or oil before tightening. Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion
or loose particles.
Tighten the lug nuts/bolts in a star pattern
until each nut/bolt has been tightened twice.
Ensure that the socket is fully engaged on the
lug nut/bolt (do not insert it halfway).
After 25 miles (40 km), check the lug nut/
bolt torque to be sure that all the lug nuts/
bolts are properly seated against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
