Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles).
SeeScheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like
it did when the tires were new.
The first rotation is the most
important. See Scheduled
Maintenance on page 11‑2.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑53 andWheel
Replacement on page 10‑59.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in
the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See Tire Pressure on
page 10‑45 andVehicle Load
Limits on page 9‑12. Reset the Tire Pressure Monitor
System. See
Tire Pressure
Monitor Operation on
page 10‑48.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 12‑2.
{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 10‑61.

Vehicle Care 10-53
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Make sure the spare tire, if
the vehicle has one, is stored
securely. Push, pull, and then
try to rotate or turn the tire.
If it moves, tighten the cable.
SeeTire Changing on
page 10‑71.When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear when the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See
Tire
Inspection on page 10‑51 andTire
Rotation on page 10‑52 for more
information.
The rubber in tires ages over time.
This also applies for the spare tire,
if the vehicle has one, even if it is
never used. Multiple conditions
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. Tires will typically
need to be replaced due to wear
before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.

7. Start the vehicle. The vehiclemust be running while using the
air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off button (B) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (C) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only. 10. Inflate the tire to the
recommended inflation
pressure using the pressure
gauge (C). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑45.
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 pressure
reading. The compressor may
be turned on/off until the
correct pressure is reached.
Notice: If the recommended
pressure cannot be reached
after approximately 25 minutes,
the vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate the tire. Remove the power plug
from the accessory power
outlet and unscrew the inflating
hose from the tire valve. See
Roadside Assistance Program
(U.S. and Canada) on page 13‑8
or
Roadside Assistance Program
(Mexico) on page 13‑10.
11. Press the on/off button (B) to turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire;
therefore, Steps 12 through 18
must be done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor
kit as it could be warm after
usage.

12. Unplug the power plug (H) fromthe accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power
plug (H) back in their original
location.
16. If the flat tire was able toinflate to the recommended
inflation pressure, remove the
maximum speed label from the
sealant canister (E) and place
it in a highly visible location.
The label is a reminder not to
exceed 90 km/h (55 mph) until
the damaged tire is repaired or
replaced.
17. Return the equipment to its original storage location in the
vehicle.
18. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire. 19. Stop at a safe location and
check the tire pressure.
Refer to Steps 1 through 11
under “Using the Tire Sealant
and Compressor Kit without
Sealant to Inflate a Tire
(Not Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
below the recommended
inflation pressure, stop driving
the vehicle. The tire is too
severely damaged and the
tire sealant cannot seal the
tire. See Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside
Assistance Program (Mexico)
on page 13‑10.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tire to the recommended
inflation pressure.

6. Plug the power plug (H) into theaccessory 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
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (A) clockwise to the Air Only
position.
9. Press the on/off (B) button to turn the compressor on.
The compressor will inflate the
tire with air only. 10. Inflate the tire to the
recommended inflation
pressure using the pressure
gauge (C). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑45.
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). 11. Press the on/off button (B)
to turn the tire sealant and
compressor kit off.
Be careful while handling the
tire sealant and compressor
kit as it could be warm after
usage.
12. Unplug the power plug (H) from the accessory power outlet in
the vehicle.
13. Disconnect the air only hose (G) from the tire
valve stem by turning it
counterclockwise, and replace
the tire valve stem cap.
14. Replace the air only hose (G) and the power plug (H) and
cord back in their original
locations.

10-82 Vehicle Care
Have the hoist shaft assembly
inspected as soon as you can.
You will not be able to store a spare
tire using the hoist assembly until it
has been repaired or replaced.
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.
