Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, including the spare tireand wheel assembly. The TPMSsensors monitor the air pressure in
the tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. SeeVehicle LoadLimits0226.
AmessagetocheckthepressureinaspecifictiremaydisplayintheDriver Information Center (DIC). Thelow tire pressure warning light andthe DIC warning message,if equipped, come on at eachignition cycle until the tires areinflated to the correct inflationpressure. Using the DIC, it may bepossible to view the tire pressure
levels. For additional informationand details about the DIC operationand displays, seeDriver InformationCenter (DIC)0108.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that theair pressure is getting low andneeds to be inflated to the properpressure.
ATire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. SeeVehicle LoadLimits0226,foranexampleoftheTire and Loading Information labeland its location. Also seeTirePressure0309.
The TPMS can warn about a lowtire pressure condition, but it doesnot replace normal tiremaintenance. SeeTire Inspection0315,Tire Rotation0315,andTires0303.

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.
Factory-installed Tire Inflator Kitsuse a GM approved liquid tiresealant. Using non-approved tiresealants could damage the TPMSsensors. SeeTire Sealant andCompressor Kit0323forinformation regarding the inflator kitmaterials and instructions.
TPMS Malfunction Light and
Message
The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire pressure warning light,
defined above, flashes for aboutone minute and then stays on forthe remainder of the ignition cycle.ADICwarningmessagemayalsodisplay. The malfunction light andDIC warning message, if equipped,come on at each ignition cycle untilthe problem is corrected. Some ofthe conditions that can cause theseto come on are:
.One of the road tires has beenreplaced with the spare tire. Thespare tire does not have aTPMS sensor. The malfunctionlight and the DIC message,if equipped, should go off afterthe road tire is replaced and thesensor matching process isperformed successfully. See"TPMS Sensor MatchingProcess" later in this section.
.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires or exchanging aroad tire with the spare tire. Themalfunction light and the DICmessage, if equipped, should gooff after successfully completing
the sensor matching process.See "TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage, if equipped, should gooff when the TPMS sensors areinstalled and the sensormatching process is performedsuccessfully. See your dealer forservice.
.Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0317.
.Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.
If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealer

TPMS Sensor Matching
Process
Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’stiresorreplacingoneormore of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacingasparetirewitharoadtirecontaining the TPMS sensor. Themalfunction light and the DICmessage, if equipped, should go offat the next ignition cycle. Thesensors are matched to the tire/wheel positions, using a TPMSrelearn tool, in the following order:left front tire, right front tire, rightrear tire, and left rear tire. See yourdealer for service or to purchase arelearn tool. A TPMS relearn toolcan also be purchased. See TirePressure Monitor Sensor ActivationTo o l a t
www.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).
There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.
The TPMS sensor matchingprocess is:
1. Set the parking brake.
2. Place the vehicle power modein ON/RUN/START. SeeIgnition Positions0229.
3. Press MENU to select theVehicle Information Menu inthe Driver InformationCenter (DIC).
4. Use the thumbwheel to scroll tothe Tire Pressure Menu Itemscreen.
5. Press and hold SET/CLR tobegin the sensor matchingprocess.

11 . P r o c e e d t o t h e l e f t r e a r t i r e ,and repeat the procedure inStep 8. The horn sounds twotimes to indicate the sensoridentification code has beenmatched to the left rear tire,and the TPMS sensor matchingprocess is no longer active.The TIRE LEARN or TIRELEARNING ACTIVE messageon the infotainment displaygoes off.
12. Turn the vehicle off.
13. Set all four tires to therecommended air pressurelevel as indicated on the Tireand 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.
.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.
Tire Rotation
The tires should be rotated
every 12 000 km/7,500 mi. See
Maintenance Schedule0349.
Tires are rotated to achieve
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. SeeWhen It Is Time
for New Tires0316andWheel
Replacement0320.
Different tire sizes should not be
rotated front to rear.

Vehicle Care 321
Some aluminum wheels can berepaired. See your dealer if any ofthese conditions exist.
Yo u r d e a l e r w i l l k n o w t h e k i n d o fwheel that is needed.
Each new wheel should have thesame load-carrying capacity,diameter, width, offset, and bemounted the same way as the one itreplaces.
Replace wheels, wheel bolts, wheelnuts, or Tire Pressure MonitorSystem (TPMS) sensors with newGM original equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
acrash.Alwaysusethecorrect
wheel, wheel bolts, and wheel
nuts for replacement.
Caution
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.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.

17. Tighten the wheel nuts firmlywith the wheel wrench.
Storing a Flat or Spare Tire
and Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
Replace the jack, tools, containerand flat tire in the trunk by reversingthe steps used to remove them.
Full-Size Spare Tire
If this vehicle came with a full-sizespare tire, it was fully inflated whennew, however, it can lose air overtime. Check the inflation pressureregularly. SeeTire Pressure0309andVehicle Load Limits0226forinformation regarding proper tireinflation and loading the vehicle. Forinstructions on how to remove,install, or store a spare tire, seeTireChanging0329.
After installing the spare tire on thevehicle, stop as soon as possibleand check that the spare is correctlyinflated. The spare tire is made toperform well at speeds up to11 2 k m / h ( 7 0 m p h ) a t t h erecommended inflation pressure, soyou can finish your trip.
The full-size spare includes a TPMSsensor. The TPMS will not monitoror display the spare tire air pressureuntil the tire/wheel is installed at oneof the four tire/wheel positions onthe vehicle and matched to the newposition. SeeTire Pressure MonitorOperation0312for informationabout matching the spare tire tothe TPMS.
Have the damaged or flat road tirerepaired or replaced and installedback onto the vehicle as soon aspossible so the spare tire will beavailable in case it is needed again.Do not mix tires and wheels ofdifferent sizes, because they will notfit. Keep the spare tire and its wheeltogether.
