6. Turn the wrench clockwise toraise the cable back up after
removing the spare tire.
Do not store a full-size or a flat
road tire under the vehicle. See
“Storing a Flat or Spare Tire and
Tools” later in this section.
To continue changing the flat tire,
see “Removing the Flat Tire and
Installing the Spare Tire” later in this
section.
If the spare tire will not lower, the
secondary latch could be engaged. Do the following to check the cable:
1. Check under the vehicle to see if
the cable is visible.
2. If it is not visible, see Secondary
Latch System on page 10‑74.
If it is visible, first try to tighten
the cable by turning the lug
wrench clockwise until you hear
two clicks or feel it skip twice.
You cannot over-tighten the
cable.
3. Loosen the cable by turning the wrench counterclockwise three
or four turns.
4. If the spare tire has not lowered, tighten the cable all the way and
then loosen it at least two times.
If the spare tire did lower to the
ground, continue with Step 5
under “Removing the Spare Tire
(Vehicles with the Rear
Convenience Center)” listed
previously. 5. If you still cannot lower the spare
tire to the ground, see
Secondary Latch System
on
page 10‑74.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. See If a Tire Goes
Flat
on page 10‑56for more
information.
2. If the vehicle has a wheel cover, loosen the plastic nut caps with
the wheel wrench. They will not
come off. Then, using the flat
end of the wheel wrench, pry
along the edge of the cover until
it comes off. Be careful; the
edges may be sharp. Do not try
to remove the cover with your
bare hands.
Store the wheel cover securely
in the rear of the vehicle until
you have the flat tire repaired or
replaced.

7. Place the jack under the vehicleas identified in Step 4. Raise the
vehicle by turning the lug wrench
clockwise in the jack. Raise the
vehicle far enough off the
ground so that there is enough
room for the spare tire to fit
under the wheel well.
8. Remove all the wheel nuts and the flat tire.9. Remove the plastic spare tire
heat shield by pulling the rubber
latch. Store the plastic spare tire
heat shield. See “Storing a Flat
or Spare Tire and Tools” later in
this section for more information.
{WARNING
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
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, 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. See If a Tire Goes Flat
on page 10‑56.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.

Vehicle Care 10-77
Compact Spare Tire
{WARNING
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
The compact spare tire, if the
vehicle has one, was fully inflated
when the vehicle was new, however,
it can lose air after a time. Check
the inflation 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 inflated. 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
finish 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 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 the compact spare on
other vehicles. And do not mix the compact spare
tire or wheel with other wheels or
tires. They will not fit. 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 fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.
