Tire Pressure Monitor
This vehicle may have a TirePressure Monitor System (TPMS).
The low tire pressure warning lightalerts to a significant loss inpressure of one of the vehicle'stires. If the warning light comes on,stop as soon as possible and inflatethe tires to the recommendedpressure shown on the Tire andLoading Information label. SeeVehicle Load Limits0171.Thewarning light will remain on until thetire pressure is corrected.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thismay be an early indicator that thetire pressures are getting low andthe tires need to be inflated to theproper pressure.
The TPMS does not replace normalmonthly tire maintenance. Maintainthe correct tire pressures.

When the Light Flashes First andThen Is On Steady
If the light flashes for about a minuteand then stays on, there may be aproblem with the TPMS. If theproblem is not corrected, the lightwill come on at every ignition cycle.SeeTire Pressure MonitorOperation0262.
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
This light should come on briefly asthe engine is started. If it does notcome on, have the vehicle servicedby your dealer.
If the light comes on and stays on, itmeans that oil is not flowing throughthe engine properly. The vehiclecould be low on oil and might havesome other system problem. Seeyour dealer.

load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
Do not forget the spare tire,
if the vehicle has one. See
Full-Size Spare Tire0282for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.
Tire Pressure Monitor
System
The Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitor
the air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare(if provided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)
As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantlyunder-inflated.
Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and can

lead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.
Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.
Yo u r v e h i c l e h a s a l s o b e e nequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.
When the malfunction indicator isilluminated, the system may not beable to detect or signal low tire
pressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.

SeeRadio FrequencyStatement0322.
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, excluding 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 LoadLimits0171.
AmessagetocheckthepressureinaspecifictiredisplaysintheDriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tires areinflated to the correct inflationpressure. If the vehicle has DICbuttons, tire pressure levels can beviewed. For additional information

and details about the DIC operationand displays, seeDriver InformationCenter (DIC)0108andTireMessages011 8.
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 LoadLimits0171,foranexampleoftheTire and Loading Information labeland its location. Also seeTirePressure0260.
The TPMS can warn about a lowtire pressure condition but it doesnot replace normal tiremaintenance. SeeTire Inspection0265,Tire Rotation0265andTires0252.
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 properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire pressure warning lightflashes for about one minute andthen stays on for the remainder ofthe ignition cycle. A DIC warningmessage also displays. Themalfunction light and DIC warningmessage come on at each ignition
cycle until the problem is corrected.Some of the conditions that cancause these to 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 messageshould go off after the road tireis replaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.
.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed and
