Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn
the driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire and
wheel assembly on the vehicle,
excluding the spare tire. The TPMS
sensors monitor the air pressure
in the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster.At the same time, a Driver
Information Center (DIC) message
is displayed on the DIC display
screen. The low tire pressure
warning light and the DIC warning
message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 3-34andDIC
Warnings and Messages on
page 3-37.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
ination pressure for the vehicle’s
tires when they are cold. See
Loading the Vehicle on page 4-35,
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 5-51.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal
tire maintenance. SeeTire
Inspection and Rotation on
page 5-57andTires on page 5-44.
Notice:Liquid tire sealants
could damage the Tire Pressure
Monitor System (TPMS) sensors.
Sensor damage caused by using
a tire sealant is not covered
by your warranty. Do not use
liquid tire sealants.
5-54 Service and Appearance Care

TPMS Malfunction Light
and Message
The TPMS will not function properly
if one or more of the TPMS
sensors are missing or inoperable.
When the system detects a
malfunction, the low tire warning
light ashes for about one minute
and then stays on for the remainder
of the ignition cycle. A DIC warning
message is also displayed. The low
tire warning light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause the malfunction light and
DIC message to come on are:
One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The TPMS
malfunction light and DIC
message should go off once you
re-install the road tire containing
the TPMS sensor.
The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle’s tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process is
performed successfully.
See “TPMS Sensor Matching
Process” later in this section.
One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your
dealer/retailer for service.
Replacement tires or wheels do
not match the vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for the vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 5-59.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low
tire condition. See your
dealer/retailer for service if the
TPMS malfunction light and
DIC message comes on and
stays on.

8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5.
9. After hearing the conrming horn
chirp for the driver side rear tire,
check to see if the TPMS low tire
warning light and the DIC LOW
TIRE messages have turned off.
If yes, the TPMS sensors have
been relearned. Turn the ignition
switch to LOCK/OFF.
If the low tire warning light and
the SERV TPM message on the
DIC are on after completing
Step 5 for the driver side rear tire,
the sensor relearn process has
not been successful. Turn the
ignition switch to LOCK/OFF and
repeat the matching process
beginning with Step 2.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire,
for signs of wear or damage.
SeeWhen It Is Time for
New Tires on page 5-58for
more information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km).
SeeScheduled Maintenance
on page 6-4.
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.Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
SeeWhen It Is Time for
New Tires on page 5-58and
Wheel Replacement on
page 5-64.
Make sure the spare tire is
stored securely. Push, pull and
then try to rotate or turn the
tire. If it moves, use the wheel
wrench/hoist shaft to tighten
the cable. SeeChanging a
Flat Tire on page 5-66.
Service and Appearance Care 5-57

When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here. Do not
include the spare tire in the tire
rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 5-51andLoading the
Vehicle on page 4-35.Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 5-54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on page 5-96.
{CAUTION
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 you
change a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, you
can 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. SeeChanging
a Flat Tire on page 5-66.
When It Is Time for
New Tires
Various factors, such as
maintenance, temperatures,
driving speeds, vehicle loading,
and road conditions inuence
when you need new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear when
the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
5-58 Service and Appearance Care

CAUTION (Continued)
3. If you have a
four-wheel-drive vehicle,
be sure the transfer case
is in a drive gear – not in
N (Neutral).
4. Turn off the engine and do
not restart while the vehicle
is raised.
5. Do not allow passengers to
remain in the vehicle.
To be even more certain the
vehicle will not move, put blocks
at the front and rear of the tire
farthest away from the one being
changed. That would be the tire
on the other side, at the opposite
end of the vehicle.When the vehicle has a at tire,
the wheel blocks need to be set up
before changing it. The wheel
blocks are located in the tool bag in
the swing-gate for H3 models or
below the rear seat for H3T models.
