Ination - Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.Notice:Do not let anyone tell
you that under-ination or
over-ination is all right. It is
not. If your tires do not have
enough air (under-ination),
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-ination), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazards
A vehicle specic Tire and
Loading Information label is
attached to your vehicle.
Service and Appearance Care 5-43
ProCarManuals.com

This label shows your vehicle’s
original equipment tires and
the correct ination pressures for
your tires when they are cold.
The recommended cold tire
ination 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
the Vehicle on page 4-18. 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.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inated simply by
looking at them. Radial tires may
look properly inated even when
they are under-inated. Check
the tire’s ination 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 ination pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the ination pressure is
low, add air until you reach the
recommended amount.
If you overll 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 inated to the
ination pressure recommended by
the vehicle manufacturer on the
vehicle placard or tire ination
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire ination pressure label, you
should determine the proper tire
ination 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 signicantly under-inated.Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inate them to
the proper pressure. Driving on a
signicantly under-inated tire
causes the tire to overheat and can
lead to tire failure. Under-ination
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-ination
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 thesystem 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.

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. 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 turns on the low
tire pressure warning light located on
the instrument panel cluster.
5-46 Service and Appearance Care

At the same time a message to
check the pressure in a specic 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
inated to the correct ination
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 3-36andDIC
Warnings and Messages on
page 3-42.
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
shows the size of your vehicle’s
original equipment tires and
the correct ination pressure for
your vehicle’s tires when they
are cold. SeeLoading the Vehicle
on page 4-18, for an example of the
Tire and Loading Information
label and its location on your
vehicle. Also seeInflation - Tire
Pressure on page 5-43.
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 5-50andTires on page 5-38.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, included a
factory-installed Tire Inator Kit.
This kit uses a GM approved liquid
tire sealant. Using non-approved
tire sealants could damage the
TPMS sensors. See Tire Sealant

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:
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 5-51.
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
identication code. Any time
you replace one or more of the
TPMS sensors or rotate the
vehicle’s tires, the identication
codes need to be matched to the
new tire/wheel location. The sensors
are matched, to the tire/wheel
locations, 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. When increasing
the tire’s pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall. To
decrease the tire’s air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
