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. Press the Remote Keyless Entry (RKE) transmitter’slock and unlock buttons at the same time forapproximately five seconds. The horn sounds twiceto signal the receiver is in relearn mode andTIRE LEARNING ACTIVE message displays on theDIC screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem.Activate the TPMS sensor by increasing ordecreasing the tire’s air pressure for five seconds,or until a horn chirp sounds. The horn chirp,which may take up to 30 seconds to sound,confirms that the sensor identification code hasbeen matched to this tire and wheel position.
6. Proceed to the passenger side front tire, and repeatthe procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeatthe procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat theprocedure in Step 5. The horn sounds two times toindicate the sensor identification code has beenmatched to the driver side rear tire, and theTPMS sensor matching process is no longer active.The TIRE LEARNING ACTIVE message on theDIC display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressurelevel as indicated on the Tire and LoadingInformation label.
11. Put the valve caps back on the valve stems.

{WARNING:
If you use bias-ply tires on the vehicle, thewheel rim flanges could develop cracks aftermany miles of driving. A tire and/or wheelcould fail suddenly, causing a crash. Useonly radial-ply tires with the wheels onthe vehicle.
If you must replace your vehicle’s tires with those thatdo not have a TPC Spec number, make sure theyare the same size, load range, speed rating, andconstruction type (radial and bias-belted tires) as yourvehicle’s original tires.
Vehicles that have a tire pressure monitoring systemcould give an inaccurate low-pressure warning ifnon-TPC Spec rated tires are installed on your vehicle.Non-TPC Spec rated tires may give a low-pressurewarning that is higher or lower than the proper warninglevel you would get with TPC Spec rated tires. SeeTire Pressure Monitor System on page 6-57.
Your vehicle’s original equipment tires are listed on theTire and Loading Information Label. SeeLoadingthe Vehicle on page 5-18, for more information aboutthe Tire and Loading Information Label and its locationon your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size thanyour original equipment wheels and tires, this mayaffect the way your vehicle performs, including itsbraking, ride and handling characteristics, stability, andresistance to rollover. Additionally, if your vehiclehas electronic systems such as, antilock brakes, tractioncontrol, and electronic stability control, the performanceof these systems can be affected.
{WARNING:
If you add different sized wheels, your vehicle may
not provide an acceptable level of performance
and safety if tires not recommended for those
wheels are selected. You may increase the
chance that you will crash and suffer serious
injury. Only use GM specific wheel and tire
systems developed for your vehicle, and have
them properly installed by a GM certified
technician.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit duringcold temperatures, warm the kit in a heated environmentfor 5 minutes. This will help to inflate the tire faster.
Always do a safety check first. SeeIf a Tire Goes Flaton page 6-70. Do not remove any objects that havepenetrated the tire.
1. Remove the tire sealant and compressor kit from itsstorage location. SeeTire Sealant and CompressorKit Storage on page 6-79.
2. Unwrap the sealant/air hose (F) and the powerplug (G).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close tothe ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire byturning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valvestem. Turn it clockwise until it is tight.
6. Plug the power plug (G) into the accessory poweroutlet in the vehicle. Unplug all items from otheraccessory power outlets. SeeAccessory PowerOutlet(s) on page 4-34.
If the vehicle has an accessory power outlet, do notuse the cigarette lighter.
If the vehicle only has a cigarette lighter, use thecigarette lighter.
Do not pinch the power plug cord in the door orwindow.

7. Start the vehicle. The vehicle must be running whileusing the air compressor.
8. Turn the selector switch (B) clockwise to theSealant + Air position.
9. Press the on/off (A) button to turn the tire sealantand compressor kit on.
The compressor will inject sealant and air intothe tire.
The pressure gage (D) will initially show a highpressure while the compressor pushes the sealantinto the tire. Once the sealant is completelydispersed into the tire, the pressure will quicklydrop and start to rise again as the tire inflates withair only.
10. Inflate the tire to the recommended inflationpressure using the pressure gage (D). Therecommended inflation pressure can be foundon the Tire and Loading Information label.SeeInflation - Tire Pressure on page 6-54.
The pressure gage (D) may read higher than theactual tire pressure while the compressor is on.Turn the compressor off to get an accurate pressurereading. The compressor may be turned on/offuntil the correct pressure is reached.
Notice:If the recommended pressure cannot bereached after approximately 25 minutes, the vehicleshould not be driven farther. The tire is tooseverely damaged and the tire sealant andcompressor kit cannot inflate the tire. Remove thepower plug from the accessory power outletand unscrew the inflating hose from the tire valve.SeeRoadside Service on page 8-7.
11. Press the on/off button (A) to turn the tire sealantand compressor kit off.
The tire is not sealed and will continue to leak airuntil the vehicle is driven and the sealant isdistributed in the tire, therefore, Steps 12 through18 must be done immediately after Step 11.
Be careful while handling the tire sealant andcompressor kit as it could be warm after usage.
12. Unplug the power plug (G) from the accessorypower outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise toremove it from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the powerplug (G) back in their original location.

Using the Tire Sealant and Compressor
Kit without Sealant to Inflate a Tire
(Not Punctured)
To use the air compressor to inflate a tire with air onlyand not sealant:
Always do a safety check first. SeeIf a Tire Goes Flaton page 6-70.
1. Remove the tire sealant and compressor kit from itsstorage location. SeeTire Sealant and CompressorKit Storage on page 6-79.
2. Unwrap the air only hose (E) and the power plug (G).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close tothe ground so the hose will reach it.
4. Remove the tire valve stem cap from the flat tire byturning it counterclockwise.
5. Attach the air only hose (E) onto the tire valve stemby turning it clockwise until it is tight.
6. Plug the power plug (G) into the accessory poweroutlet in the vehicle. Unplug all items from otheraccessory power outlets. SeeAccessory PowerOutlet(s) on page 4-34.
If the vehicle has an accessory power outlet, do notuse the cigarette lighter.
If the vehicle only has a cigarette lighter, use thecigarette lighter.
Do not pinch the power plug cord in the door orwindow.
7. Start the vehicle. The vehicle must be running whileusing the air compressor.
8. Turn the selector switch (B) counterclockwise to theAir Only position.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damageby driving slowly to a level place. Turn on the hazardwarning flashers. SeeHazard Warning Flasherson page 4-3.
{WARNING:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you or
other people. You and they could be badly injured
or even killed.
WARNING: (Continued)
WARNING: (Continued)
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Turn off the engine and do not restart while
the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not move,
you should put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire, on the other side, at the
opposite end of the vehicle.
When the vehicle has a flat tire (B), use the followingexample as a guide to assist you in the placementof wheel blocks (A).
