Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. See Vehicle Load
Limits 0151.
(Continued)
Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a pothole.
Keep tires at the
recommended pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.

the 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 cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits 0151.
A message to check the pressure in
a specific tire may display in the
Driver Information Center (DIC). The
low tire pressure warning light and
the DIC warning message,
if equipped, come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, it may be
possible to view the tire pressure levels. For additional information
and details about the DIC operation
and displays, see
Driver Information
Center (DIC) 0113.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits 0151, for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0228.
The TPMS can warn about a low
tire pressure condition, but it does
not replace normal tire
maintenance. See Tire Inspection
0 233, Tire Rotation 0234, and
Tires 0221.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
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 pressure warning light,
defined above, flashes for about
one minute and then stays on for
the remainder of the ignition cycle.
A DIC warning message may also
display. The malfunction light and
DIC warning message, if equipped,
come on at each ignition cycle until

232 Vehicle Care
the problem is corrected. Some of
the conditions that can cause these
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 malfunction
light and the DIC message,
if equipped, should go off after
the road tire is replaced and the
sensor matching process is
performed successfully. See
"TPMS Sensor Matching
Process" later in this section.
. The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message, if equipped, should go
off after successfully completing
the sensor matching process.
See "TPMS Sensor Matching
Process" later in this section.
. One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message, if equipped, should go
off when the TPMS sensors are installed and the sensor
matching process is performed
successfully. See your dealer for
service.
. Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires 0235.
. 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
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message, if equipped,
come on and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light and the DIC
message, if equipped, should go off
at the next ignition cycle. The
sensors are matched to the tire/
wheel positions, 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. A TPMS
relearn tool can also be purchased.
See Tire Pressure Monitor
Sensor Activation Tool at
www.gmtoolsandequipment.com
or call 1-800-GM TOOLS
(1-800-468-6657).
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 sensor matching
process is:1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Use the MENU button to select the Vehicle Information Menu
(Menu 2) in the Driver
Information Center (DIC).
4. Use the thumbwheel (or up and down arrows) to scroll to the
Tire Pressure Menu Item
screen.
5. Press and hold the SET/CLR button to begin the sensor
matching process.
A message requesting
acceptance of the process may
display.
6. If requested, press the SET/ CLR button again to confirm
the selection.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE LEARN or TIRE LEARNING ACTIVE
message displays on the DIC
screen.
7. Start with the driver side front tire.
8. 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.
9. Proceed to the passenger side front tire, and repeat the
procedure in Step 8.
10. Proceed to the passenger side rear tire, and repeat the
procedure in Step 8.
11. Proceed to the driver side rear tire, and repeat the procedure
in Step 8. The horn sounds two
times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARN or TIRE LEARNING ACTIVE
message on the DIC display
screen goes off.
12. Turn the ignition to LOCK/OFF.
13. 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.
