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 speci cation. SeeCapacities and
Specifications on page 5-118for the wheel nut
torque speci cation.
9. 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 either the center cap, or bolt-on
hub cap, depending on what your vehicle is equipped
with. For center caps, place the cap on the wheel
and tap it into place until it seats ush with the wheel.The cap only goes on one way. Be sure to line up the
tab on the center cap with the indentation on the wheel.
For bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.
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 below.

To release the spare tire from the secondary latch,
do the following:
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 5-80.5. 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),
separating them so
that the jack is
balanced securely.

8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.9. Position the center lift point of the jack under the
center of the spare tire.
10. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
12. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging
by the cable.

{CAUTION:
Someone standing too close during the
procedure could be injured by the jack.
If the spare tire does not slide off the jack
completely, make sure no one is behind you
or on either side of you as you pull the jack
out from the spare.
13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while rmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert
the hoist end of extension, and wheel wrench into
the hoist shaft hole in the bumper and turn the
wheel wrench counterclockwise to lower the spare
the rest of the way.14. Tilt the tire retainer (G)
at the end of the cable
and pull it through
the wheel opening.
Pull the tire out
from under the vehicle.
15. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using
the hoist assembly until it has been replaced.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-84.

Storing a Flat or Spare Tire
and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone.
Store all these in the proper place.
Notice:Storing an aluminum wheel with a at tire
under your vehicle for an extended period of time or
with the valve stem pointing up may damage the
wheel. Always stow the wheel with the valve stem
pointing down and have the wheel/tire repaired as
soon as possible.Store the tire under the rear of the vehicle in the spare tire
carrier. Use the art and text following to help you:
A. Spare Tire (Valve
Stem Pointed Down)
B. Hoist Assembly
C. Hoist Cable
D. Tire Retainer
E. Hoist Shaft
F. Hoist End of
Extension ToolG. Hoist Shaft

H. Wheel Wrench
I. Jack Handle

6. Turn the wheel wrench clockwise to raise the tire.
After raising the tire halfway upward, check to
make sure the retainer is still seated properly across
the wheel opening and that the tire is level with
the underside of the vehicle.
7. Continue raising the tire until it is fully against the
underside of the vehicle and you hear two clicks
or feel it skip twice. You cannot overtighten
the cable.
8. For the Z71 model, to ensure that the tire is level
and positioned properly in the spare tire well, turn
the wheel wrench counterclockwise two turns
to slightly loosen the tire and wheel assembly.
Grasp the tire and make needed adjustments
to ensure that the tire is completely level and
properly positioned in the spare tire well.
Repeat Step 7.
9. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the wheel wrench to tighten the cable.
10. Reinstall the spare tire lock (if equipped).
