and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑4.
See If a Tire Goes Flat on
page 10‑58 for other important
safety warnings.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑68.
2. Unwrap the air only hose (G) and the power plug (H).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the tire valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem by turning it
clockwise until it is tight. 6. Plug the power plug (H) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑9.
If the vehicle has an accessory
power outlet, do not use the

inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10‑44.
The pressure gauge (C) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading.
The compressor may be turned
on/off until the correct pressure
is reached.
If you inflate the tire higher
than the recommended
pressure you can adjust the
excess pressure by pressing
the pressure deflation
button (D), if equipped, until the
proper pressure reading is
reached. This option is only
functional when using the air
only hose (G).

See “Storing the Spare Tire”
and “Storing the Flat Tire” later
in this section.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. See If a Tire Goes
Flat on page 10‑58 for 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.
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
wrench. For wheels with a wheel
lock key, use the wheel lock key
between the lock nut and
wrench. The key is supplied in
the front passenger door pocket.

Vehicle Care 10-71
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 30.5 cm (12 in)
from the front tire or (B) about
27 cm (10.5 in) 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. Attach the wrench to the jack,
and turn the wrench clockwise to
raise the jack head 7.6 cm (3 in).
6. Do not raise the vehicle yet. Put the compact spare tire near you.
{WARNING
Getting under a vehicle when it is
lifted on a jack 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.

10-72 Vehicle Care
{WARNING
Raising the 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.
7. Raise the vehicle by turning the 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 the
Spare Tire” 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, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
{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.
