{CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become
loose after time. The wheel could come off and
cause an accident. When you change a wheel,
remove any rust or dirt from places where the
wheel attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt off.
SeeChanging a Flat Tire on page 5-78.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces,
and spare wheel.8. Install the spare tire.{CAUTION:
Never use oil or grease on studs or nuts.
Because the nuts might come loose. The
vehicle’s wheel could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded end
of the nuts toward the wheel after mounting the
spare tire.
10. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the wheel nuts until the

{CAUTION:
Incorrect or improperly tightened wheel
nuts can cause the wheel to come loose and
even come off. This could lead to a crash.
If you have to replace them, be sure to get
new original equipment wheel nuts. Stop
somewhere as soon as you can and have the
nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-115for wheel
nut torque specication.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly tighten
the wheel nuts in the proper sequence and to
the proper torque specication. SeeCapacities
and Specifications on page 5-115for the wheel
nut torque specication.12. Tighten the
nuts rmly in a
crisscross sequence
as shown by
turning the wheel
wrench clockwise.
When you reinstall the regular wheel and tire, you
must also reinstall the center cap. Line the tab on the
back of the tab with the slot in the wheel. Place the
cap on the wheel and press until it snaps into place.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system.
It is designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work, the
spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools
on page 5-94.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not visible
proceed to Step 6.
2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You cannot
overtighten the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.

4. Repeat this procedure at least two times. If the
spare tire lowers to the ground, continue with
Step 5 ofRemoving the Spare Tire and Tools
on page 5-79.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A) on
the wheel blocks (B),

wheel wrench counterclockwise to lower the spare
the rest of the way.14. Tilt the tire retainer at the end of the cable and
pull it through the wheel opening. Pull the tire
out from under the vehicle.
