Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly that has 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 6-96.
{WARNING:
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 fitting
is visible.
2. If the cable end fitting is not visible, proceed to
Step 6.
If it is visible, first 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.
6-93

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.
15. If the cable is hanging under the vehicle, turn the
wheel wrench clockwise to raise the cable.
Have the hoist assembly inspected as soon as you
can. You will not be able to store a spare or flat
tire using the hoist assembly until it has been
replaced.
To continue changing the flat tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 6-85.
Storing a Flat or Spare Tire and
Tools
{WARNING:
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 can damage
the wheel. Always stow the wheel with the valve
stem pointing down and have the wheel/tire repaired
as soon as possible.

Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire. Although
the compact spare tire was fully inflated when your
vehicle was new, it can lose air over time. Check the
inflation pressure regularly. It should be 60 psi (420 kPa).
Notice:If the vehicle has four-wheel drive and the
compact spare tire is installed on the vehicle, do not
drive in four-wheel drive until you can have the at
tire repaired and/or replaced. You could damage the
vehicle, and the repair costs would not be covered by
your warranty. Never use four-wheel drive when the
compact spare tire is installed on the vehicle.
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
vehicle’s spare tire is correctly inflated. The compact
spare is made to perform well at speeds up to 62 mph
(100 km/h) for distances up to 500 miles (804 km).
For heavy payloads or towing, and for low traction or
four-wheel-drive conditions, repair or replace the full-size
tire. Of course, it is best to replace your vehicle’s spare
with a full-size tire as soon as you can. The spare tire
will last longer and be in good shape in case you need
it again.Notice:When the compact spare is installed,
do not take the vehicle through an automatic car
wash with guide rails. The compact spare can
get caught on the rails which can damage the
tire, wheel and other parts of the vehicle.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or wheel with
other wheels or tires. They will not fit. Keep your
spare tire and its wheel together.
Notice:Tire chains will not t the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the
compact spare.
Full-Size Spare Tire
Your vehicle may have a full-size spare tire, which,
when new, was fully inflated. A spare tire may lose
air over time, so check its inflation pressure regularly.
SeeIn ation - Tire Pressure on page 6-64andLoading
the Vehicle on page 5-33for information regarding proper
tire inflation and loading your vehicle. For instruction
on how to remove, install, or store a spare tire, see
Removing the Flat Tire and Installing the Spare Tire
on page 6-85andStoring a Flat or Spare Tire and
Tools on page 6-96.
