To continue changing the flat tire,
see “Removing the Flat Tire and
Installing the Spare Tire” later in this

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

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.

Vehicle Care 10-69
If the vehicle has aluminum
wheels, remove the wheel nut
caps using the wheel wrench.
3. Loosen the wheel nuts—but do
not remove them —using the
lug wrench. For wheels with a
wheel lock key, use the wheel
lock key between the lock nut
and lug wrench. The key is
supplied in the front passenger
door pocket.
Notice: If this vehicle has wheel
locks and an impact wrench is
used to remove the wheel nuts,
the lock nut or wheel lock key could be damaged. Do not use an
impact wrench to remove the
wheel nuts if this vehicle has
wheel locks.
4. To identify the appropriate
jacking location, find the
triangle (A) about 12 inches
(30.5 cm) from the front tire
or (B) about 10.5 inches (27 cm)
from the rear tire.
The triangle is located near each
wheel on the vehicle's exterior.
Notice: If a jack is used to raise
the vehicle without positioning it
correctly, the vehicle could be
damaged. When raising the
vehicle on a jack, avoid contact
with the rear axle control arms.
5. Do not raise the vehicle yet. Put the compact spare tire near you.
{WARNING
Getting under a vehicle when it is
jacked up is dangerous. If the
vehicle slips off the jack, you
could be badly injured or killed.
Never get under a vehicle when it
is supported only by a jack.
{WARNING
Raising your vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
6. Attach the lug wrench to the jack, and turn the wrench
clockwise to raise the jack head
3 inches (7.6 cm).

10-70 Vehicle Care
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.
