Your vehicle's TPMS can warn you about a low tirepressure condition but it does not replace normal tiremaintenance. SeeTire Inspection and Rotationonpage 7!71andTires on page 7!58.
Notice:Liquid tire sealants could damage the TirePressure Monitor System (TPMS) sensors. Sensordamage caused by using a tire sealant is notcovered by your warranty. Do not use liquid tiresealants.
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more ofthe TPMS sensors are missing or inoperable. When thesystem detects a malfunction, the low tire warning lightflashes for about one minute and then stays on for theremainder of the ignition cycle. A DIC warning messageis also displayed. The low tire warning light and DICwarning message come on at each ignition cycle untilthe problem is corrected. Some of the conditions thatcan cause the malfunction light and DIC message tocome on are:
.One of the road tires has been replaced with thespare tire. The spare tire does not have a TPMSsensor. The TPMS malfunction light and DICmessage should go off once you re!install theroad tire containing the TPMS sensor.
.The TPMS sensor matching process was startedbut not completed or not completed successfullyafter rotating the vehicle's tires. The DIC messageand TPMS malfunction light should go off once theTPMS sensor matching process is performedsuccessfully. See“TPMS Sensor MatchingProcess”later in this section.
.One or more TPMS sensors are missing ordamaged. The DIC message and the TPMSmalfunction light should go off when the TPMSsensors are installed and the sensor matchingprocess is performed successfully. See yourdealer/retailer for service.
.Replacement tires or wheels do not match yourvehicle's original equipment tires or wheels. Tiresand wheels other than those recommended foryour vehicle could prevent the TPMS fromfunctioning properly. SeeBuying New Tiresonpage 7!73.
.Operating electronic devices or being near facilitiesusing radio wave frequencies similar to the TPMScould cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signala low tire condition. See your dealer/retailer for serviceif the TPMS malfunction light and DIC message comeson and stays on.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.Any time you rotate your vehicle's tires or replace oneor more of the TPMS sensors, the identification codeswill need to be matched to the new tire/wheel position.The sensors are matched to the tire/wheel positionsin the following order: driver side front tire, passengerside front tire, passenger side rear tire, and driverside rear tire using a TPMS diagnostic tool. See yourdealer/retailer for service.
The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's airpressure. If increasing the tire's air pressure, do notexceed the maximum inflation pressure indicated on thetire's sidewall.
To decrease air-pressure out of a tire you can use thepointed end of the valve cap, a pencil-style air pressuregage, or a key.
You have two minutes to match the first tire/wheelposition, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, tomatch the first tire and wheel, or more than five minutesto match all four tire and wheel positions the matchingprocess 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 theengine off.
3. PressQandKon the Remote Keyless Entry
(RKE) transmitter at the same time forapproximately five seconds. The horn sounds twiceto signal the receiver is in relearn mode and TIRELEARNING ACTIVE message displays on the DICscreen.
4. Start with the driver side front tire.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use spare
tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction–AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire's ability to stop on wet pavement as measured
under controlled conditions on specified
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.

Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. SeeEngine Oilonpage 7!17.An Emission Control Service.
When the Change Engine Oil Soon message displays,service is required for the vehicle as soon as possible,within the next 1 000 km/600 miles. If driving under thebest conditions, the engine oil life system might notindicate the need for vehicle service for more than ayear. The engine oil and filter must be changed at leastonce a year and the oil life system must be reset. Yourdealer/retailer has trained service technicians who willperform this work and reset the system. If the engine oillife system is reset accidentally, service the vehiclewithin 5 000 km/3,000 miles since the last service. Resetthe oil life system whenever the oil is changed. SeeEngine Oil Life System on page 7!20.
When the Change Engine Oil Soon message displays,certain services, checks, and inspections are required.
