Page 318 of 420
When to Check
Check your tires once a month
or more. Do not forget to check
the compact spare tire, if the
vehicle has one. It should be at
60 psi (420 kPa). For additional
information regarding the
compact spare tire, seeCompact
Spare Tire on page 5-81.
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
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. 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.)
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.

Changes or modi cations to
this system by other than an
authorized service facility could void
authorization to use this equipment.
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, excluding the
spare tire and wheel assembly,
if the vehicle has one. The TPMS
sensors monitor the air pressure in
the vehicle’s tires and transmits
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 message to
check the pressure in a speci c tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on 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 (With DIC Buttons) on
page 3-46orDIC Operation and
Displays (Without DIC Buttons) on
page 3-51andDIC Warnings and
Messages on page 3-56.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 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 ation pressure for
your vehicle’s tires when they
are cold. SeeLoading the Vehicle
on page 4-16, for an example of
the Tire and Loading Information
label and its location on your
vehicle. Also seeInflation - Tire
Pressure on page 5-41.
Your 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 5-47andTires
on page 5-35.

Notice:Using non-approved tire
sealants could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use the
GM approved tire sealant available
through your dealer/retailer.
Your vehicle, when new, may have
included a factory-installed Tire
In ator Kit. This kit uses a GM
approved liquid tire sealant. Using
non-approved tire sealants could
damage the TPMS sensors.
See Tire Sealant and Compressor
Kit for information regarding the
in ator kit materials and instructions.
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 ignitioncycle. 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, if
your vehicle has one. 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 your vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 5-49.
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.

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identi cation code. Any time
you rotate your vehicle’s tires or
replace one or more of the TPMS
sensors, 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/
retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum in ation pressure
indicated on the tire’s sidewall.
To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gage, or a key.You have two minutes to match
the rst tire/wheel position, and
ve minutes overall to match
all four tire/wheel positions. If it
takes longer than two minutes, to
match the rst tire and wheel, or
more than ve minutes to match all
four tire and wheel positions the
matching process stops and you
need to start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press the Remote Keyless
Entry (RKE) transmitter’s LOCK
and UNLOCK buttons at the
same time for approximately
ve 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. Remove the valve cap from the
valve cap 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 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. The horn sounds two
times to indicate the sensor
identi cation code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.

Wheel Alignment and
Tire Balance
The tires and wheels on your vehicle
were aligned and balanced carefully
at the factory to give you the longest
tire life and best overall performance.
Adjustments to wheel alignment and
tire balancing will not be necessary
on a regular basis. However, if you
notice unusual tire wear or your
vehicle pulling to one side or the
other, the alignment might need to be
checked. If you notice your vehicle
vibrating when driving on a smooth
road, the tires and wheels might
need to be rebalanced. See your
dealer/retailer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the
one it replaces.
If you need to replace any of your
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure to
have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors for
your vehicle.{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which
you or others could be injured.
Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
