using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS matching process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN withthe engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and
unlock buttons at the same time
for approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and Tire Learning Active
message displays on the DIC
screen. 4. Start with the driver side
front tire.
5. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in
Step 5. After hearing the
confirming horn chirp, for the
driver side rear tire, the horn
sounds two more times to signal
the tire learning mode is no
longer active.
9. Turn the ignition to LOCK/OFF. 10. Set all four tires to the
recommended air pressure
level as indicated on the tire
and loading information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.

Vehicle Care 10-77
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
If the vehicle has non-directional
tires, they should be rotated
every 12 000 km/7,500 mi. See
Maintenance Schedule on
page 11‑3.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as soon
as possible and check the wheel
alignment. Also check for
damaged tires or wheels. See
When It Is Time for New Tires
on page 10‑78andWheel
Replacement on page 10‑82. Directional tires should not be
rotated. Each tire and wheel
should be used only in the
position it is in. Directional tires
will have an arrow on the tire
indicating the proper direction of
rotation or will have
“left”or
“right” molded on the sidewall.
Use this rotation pattern if the
vehicle has different size tires
on the front and rear and they
are non-directional. Different tire sizes should not be
rotated front to rear.
Use this rotation pattern when
rotating tires of the same size
installed on all four wheel
positions.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after

the tires have been rotated. See
Tire Pressure on page 10‑70
andVehicle Load Limits on
page 9‑11.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑73.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
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
(Continued)
WARNING (Continued)
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.
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.
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 10‑76 andTire
Rotation on page 10‑77 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

{WARNING
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
(Continued)
WARNING (Continued)
4. Do not allow passengers toremain in the vehicle.
5. Place wheel blocks on both sides of the tire at the
opposite corner of the tire
being changed.
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. To use the jacking
equipment to change a spare tire
safely, follow the instructions below.
Then see Tire Changing on
page 10‑95. To use the tire sealant
and compressor kit, see Tire
Sealant and Compressor Kit on
page 10‑86. When the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).

The following information explains
how to repair or change a tire.
Tire Sealant and
Compressor Kit
{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust on page 9‑26.
{WARNING
Overinflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inflate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{WARNING
Storing the tire sealant and
compressor kit 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 the tire
sealant and compressor kit in its
original location. If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be
used to inflate an under inflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire
sealant and compressor kit to be
effective. See
Roadside Service
(U.S. and Canada) on page 13‑7 or
Roadside Service (Mexico) on
page 13‑9.
Read and follow all of the tire
sealant and compressor kit
instructions.
