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 5-84.

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
tting is visible.
2. If the cable end tting is not visible, proceed to
Step 6.

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 wheel wrench
counterclockwise three or four turns.

Spare Tire
Compact Spare Tire
Your vehicle may be equipped with a compact spare
tire. Although the compact spare tire was fully inated
when your vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure your
spare tire is correctly inated. The compact spare is
made to perform well at speeds up to 65 mph (105 km/h)
for distances up to 3,000 miles (5 000 km), so you can
nish your trip and have your full-size tire repaired or
replaced where you want. For heavy payloads or towing,
and for low traction or four-wheel-drive conditions,
repair or replace the full-size tire, and reinstall for best
performance. Of course, it’s best to replace your spare
with a full-size tire as soon as you can. Your spare
will last longer and be in good shape in case you
need it again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic car
wash with guide rails. The compact spare can
get caught on the rails. That can damage the tire
and wheel, and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t t. Keep your spare tire
and its wheel together.
Notice:Tire chains will not t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.
Full-Size Spare Tire
Your vehicle may be equipped with a full-size spare tire,
which, when new, was fully inated. A spare tire, whether
compact-size or full-size, may lose air over time, so check
its ination pressure regularly. SeeInation - Tire
Pressure on page 5-60andLoading Your Vehicle on
page 4-44for information regarding proper tire ination
and loading your vehicle. For instruction on how to
remove, install or store a spare tire, seeChanging a Flat
Tire on page 5-70.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Don’t mix tires and wheels of different sizes, because
they won’t t. Keep your spare tire and its wheel together.
