Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time.
The wheel could come off and cause an
accident. When changing a wheel, remove
any rust or dirt from the places where the
wheel attaches to the vehicle. In an
emergency, a cloth or a paper towel can
be used to do this; but be sure to use a
scraper or wire brush later, if needed,
to get all the rust or dirt off.
{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 serious accident.

Secondary Latch System
Your vehicle has an underbody mounted tire
hoist assembly that has a secondary latch
system. It is designed to stop the compact
spare tire from suddenly falling off your vehicle
if the cable holding the spare tire is damaged.
For the secondary latch to work, the tire must be
stowed with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and Tools
on page 472for instructions on storing the
spare tire correctly.{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:
{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 under spare.
1. If the cable is not visible, start this procedure
at Step 3.
2. Turn the lug wrench counterclockwise until
approximately 6 inches (15 cm) of cable is
exposed.

3. Attach the lug wrench to the jack and raise
the jack at least 10 turns.
4. Place the jack under the vehicle, ahead of the
rear bumper. Position the center lift point of
the jack under the center of the spare tire.

Storing a Flat or Spare Tire
and Tools
Storing the Spare Tire
{CAUTION:
The underbody-mounted spare tire needs
to be stored with the valve stem pointing
down. If the spare tire is stored with the
valve stem pointing upwards, its
secondary latch will not work properly
and the spare tire could loosen and
suddenly fall from your vehicle. If this
happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of
course, damage to itself as well. Be sure
the underbody-mounted spare tire is
stored with its valve stem pointing down.
{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.
To store the spare tire:
1. Lay the compact spare tire near the rear of
the vehicle with the valve stem down.
2. Reinstall the plastic spare tire heat shield on
the compact spare tire.
3. If the vehicle has aluminum wheels, remove
the small center cap by tapping the back of
the cap with the extension of the shaft.
472

4. Slide the cable retainer through the center of
the wheel and start to raise the compact
spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
5. When the compact spare tire is almost in the
stored position, turn the tire so the valve is
toward the rear of the vehicle.
This position helps when checking the air
pressure in the compact spare tire.
6. Raise the tire fully against the underside of
the vehicle. Continue turning the lug wrench
until you feel more than two clicks. This
indicates that the compact spare tire is secure
and the cable is tight. The spare tire hoist
cannot be overtightened.
7. Make sure the tire is stored securely. Push,
pull (A), and then try to turn (B) the tire. If the
tire moves, use the lug wrench to tighten
the cable.
473

Storing the Flat Tire
Notice:Storing the full-size at tire in the
underbody hoist system can expose it to heat
from the exhaust system. This can damage
the tire and underbody hoist system. Do not
store the full-size at tire in the underbody
hoist system.
1. Remove the cable package from the jack
storage area.
2. Remove the small center cap by tapping the
back of the cap with the extension of the
shaft, if the vehicle has aluminum wheels.
3. Put the at tire in the rear storage area with
the valve stem pointing toward the rear of the
vehicle.4. Hook on end of the cable onto the outside
portion of the liftgate hinge opposite (B).
5. Pull the cable (A) through the door striker (E),
the center of the wheel (D), and the plastic
spare tire heat shield (C), as shown.

Storing the Tools
A. Tool Bag
B. Wing Bolt
C. JackPut back all tools as they were stored in the jack
storage compartment and put the compartment
cover back on.
1. Make that the bottom of the jack is facing
toward you.
2. Turn the jack (C) on its side and place it down
on the holding bracket.
3. Reinstall the wing bolt (B) by turning it
clockwise.
4. To replace the cover, line up the tabs on the
bottom of the cover with the slots in the cover
opening. Push the cover in place, insuring
that the upper front and rear tabs are in
the opening and push the cover closed. Make
sure that the center latch is fully engaged.
This secures the cover in place.
Store the center cap or the plastic bolt-on wheel
covers until a full size tire is put back on the
vehicle. When you replace the compact spare with
a full-size tire, reinstall the bolt-on wheel covers
or the center cap. Hand-tighten them over
the wheel nuts, using the lug wrench.
476

Compact Spare Tire
Although the compact spare tire was fully inated
when the 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 the vehicle,
stop as soon as possible and make sure the
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
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible.
The spare tire will last longer and be in good
shape in case it is needed 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.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
The All-Wheel Drive (AWD) system will be
automatically disabled when you use the compact
spare. To restore the AWD and prevent
excessive wear on the clutch in your AWD,
replace the compact spare tire with a full-size tire
as soon as possible.
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.
