In ation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-in ation or over-in ation is all right.
It is not. If your tires do not have enough air
(under-in ation), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-in ation),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA Tire and Loading Information label is attached to
the vehicle’s center pillar (B-pillar). This label
shows your vehicle’s original equipment tires and
the correct in ation pressures for your tires
when they are cold. The recommended cold tire
in ation pressure, shown on the label, is the
minimum amount of air pressure needed to
support your vehicle’s maximum load carrying
capacity.
For additional information regarding how much
weight your vehicle can carry, and an example
of the Tire and Loading Information label,
seeLoading Your Vehicle on page 315. How you
load your vehicle affects vehicle handling and
ride comfort. Never load your vehicle with more
weight than it was designed to carry.
When to Check
Check your tires once a month or more. Do not
forget to check the compact spare tire, it should be
at 60 psi (420 kPa). For additional information
regarding the compact spare tire, seeCompact
Spare Tire on page 416.

How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly in ated simply by looking at them. Radial
tires may look properly in ated even when they
are under-in ated. Check the tire’s in ation
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
in ation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
in ation pressure is low, add air until you reach the
recommended amount.
If you over ll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor
System (TPMS). This system uses radio and
sensor technology to check tire pressure levels.
TPMS sensors are mounted onto each tire
and wheel assembly, except for the spare tire.
The TPMS sensors monitor the air pressure
in your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
Each tire, including the spare (if provided), should
be checked monthly when cold and in ated to
the in ation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire
in ation pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire in ation pressure label,
you should determine the proper tire in ation
pressure for those tires.)
391

As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires
is signi cantly
under-in ated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and in ate them to the
proper pressure. Driving on a signi cantly
under-in ated tire causes the tire to overheat and
can lead to tire failure. Under-in ation also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even
if under-in ation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will ash for approximately
one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
392
Page 393 of 492
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a message to check
the pressure in a speci c tire will appear on the
Driver Information Center (DIC) display. The
low tire pressure warning symbol on the instrument
panel cluster and the check tire pressure
message will appear at each ignition cycle until
the tires are in ated to the correct in ation
pressure. Using the DIC, tire pressure levels can
be viewed by the driver. For additional information
and details about the DIC operation and displays
seeDIC Operation and Displays on page 193
andDIC Warnings and Messages on page 198.
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 may be
an early indicator that the air pressure in the
tire(s) are getting low and need to be in ated to
the proper pressure.
A Tire and Loading Information Label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct in ationpressure for your vehicle’s tires when they are cold.
SeeLoading Your Vehicle on page 315, for an
example of the Tire and Loading Information
Label and its location on your vehicle. Also see
In ation - Tire Pressure on page 390.
Your vehicle’s TPMS system can warn you about a
low tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 396andTires on page 382.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable. If
the system detects a missing or inoperable sensor,
an error message SERVICE TIRE MONITOR
SYSTEM will be shown on the DIC display. If you
have replaced a tire/wheel assembly without
transferring the TPMS sensors, the error message
will be displayed. Once you re-install the TPMS
sensors, the error message should go off. See your
dealer for service if all TPMS sensors are installed
and the error message comes on and stays on.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identi cation
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identi cation codes will need to be matched to
the new tire/wheel position. The sensors are
matched, to the tire/wheel positions, in the
following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum in ation
pressure indicated on the tire’s sidewall.
You will have two minutes to match each tire
and wheel position. If it takes longer than
two minutes to match any tire and wheel position,
the matching process stops and you will need
to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle
information button until the TIRE LOCATIONS
PRESS
VTO LEARN message displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate the receiver is ready, and
the TIRE LEARNING ACTIVE message
displays. The TPMS system is ready for the
sensor matching process to begin.
5. Start with the driver side front tire.
394
Page 395 of 492
6. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds. The
horn chirp, which may take up to 30 seconds to
sound, con rms that the sensor identi cation
code has been matched to the tire/wheel
position. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a
pencil-style air pressure gage, or a key.
7. Proceed to the passenger side front tire,
and repeat the procedure in Step 6.
8. Proceed to the passenger side rear tire,
and repeat the procedure in Step 6.
9. Proceed to the driver side rear tire, and
repeat the procedure in Step 6.
10. After hearing the con rming horn chirp for the
driver side rear tire, the tire learning process
ends. Turn the ignition switch to LOCK.
11. Set all four tires to the recommended air
pressure level as indicated on the tire and
loading information label.
12. Put the valve caps back on the valve stems.Federal Communications Commission

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
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 397
andWheel Replacement on page 402for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst
rotation is the most important. SeeScheduled
Maintenance on page 439for scheduled rotation
intervals.When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the
front and rear in ation pressures as shown on
the Tire and Loading Information label. See
In ation - Tire Pressure on page 390and
Loading Your Vehicle on page 315.

Reset the Tire Pressure Monitor System. See
“TPMS Sensor Matching Process” under
Tire Pressure Monitor System on page 391.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Speci cations on page 434.
{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 404.
When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see 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.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
