The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to Acc.
3. Using the keyless access transmitter, lock and
unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the keyless access transmitter. A single
horn chirp will sound, indicating that the TPMS
is ready, and the sensor matching process
can begin.
5. Start with the driver side front tire.
6. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds to sound,
con rms that the sensor identi cation code has
been matched to this tire position.
7. Proceed to the passenger side front tire, and repeat
the procedure in Step 6.
8. Proceed to the passenger side rear tire, and repeat
the procedure in Step 6.
9. Proceed to the driver side rear tire, and repeat the
procedure in Step 6.10. After hearing the con rming single horn chirp for the
driver side rear tire, a double horn chirp will sound to
signal the tire matching mode is no longer active.
Press the push-button ignition switch to Acc.
11. Set all four tires to the recommended air pressure
level as indicated on the tire and loading information
label.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs of
wear or damage. SeeWhen It Is Time for New
Tires on page 5-75for more information.
Tire rotation is not recommended if your vehicle
has the following performance tire combinations:
P235/50R17 size tires on the front wheels
and P255/45R17 size tires on the rear wheels.
P235/50ZR18 size tires on the front wheels
and P255/45ZR18 size tires on the rear
wheels.
P255/45R18 size tires on the front wheels and
P275/40R19 size tires on the rear wheels.

Your vehicle’s original equipment tires are listed on the
Tire and Loading Information label. SeeLoading
Your Vehicle on page 4-26, for more information about
the Tire and Loading Information label and its location
on your vehicle.
Vehicles that have performance tires P235/50R17 95V
(front axle) and P255/45R17 98V (rear axle) are mounted
on wheels with different rim widths. The front axle tires
are mounted on rims 7.5 inches (19.05 cm) wide and
the rear axle tires require wheels with a minimum rim
width of 8 inches (20.32 cm). The original equipment
wheels designed for P255/45R17 98V size tires are
etched with the words REAR ONLY. When replacing
P255/45R17 98V size tires have them mounted on
wheels with a minimum width of 8 inches (20.32 cm) and
marked REAR ONLY. SeeWheel Replacement on
page 5-80.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability,
and resistance to rollover. Additionally, if your vehicle
has electronic systems such as, anti-lock brakes,
traction control, and electronic stability control,
the performance of these systems can be affected.
{CAUTION:
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
speci c wheel and tire systems developed for
your vehicle, and have them properly installed
by a GM certi ed technician.
SeeBuying New Tires on page 5-76andAccessories
and Modifications on page 5-3for additional information.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle or the
vehicle may fall and cause your or others injury.
If you ever use a jack to lift your vehicle, follow the
instructions that came with the jack, and be sure to use
the correct lifting points to avoid damaging your vehicle.Notice:Lifting your vehicle improperly can damage
your vehicle and result in costly repairs not
covered by your warranty. To lift your vehicle
properly, follow the advice in this part.
To help prevent vehicle damage:
Be sure the jack you are using meets the weight
standards for your vehicle and is in good
working order.
Be sure to place a block or pad between the
jack and the vehicle.
Make sure the jack you are using only contacts
the jacking location lift points and is not leaning
on any other vehicle components such as the
rocker panels, the oor pan, or the stone guard
moldings.
Lift only in the areas shown in the following
pictures.

tabs of the quick
release buckle.
4. Remove the sealant and compressor kit from its
foam container.
Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal small punctures in the
tread area of the tire. The sealant cannot seal sidewall
damage, large punctures, or a tire that has unseated
from the wheel. SeeRoadside Service on page 7-6if
you need assistance.The sealant can only be used to seal one tire. After
usage, the sealant canister and sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in
this section.
Check the tire sealant expiration date on the sealant
canister, if it has expired, see your dealer/retailer for a
replacement.
Using the Tire Sealant and
Compressor Kit
Follow these directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem cap or tire pressure
monitoring sensor from the at tire by turning
it counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.

accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 3-46for more
information.
Do not slam door or close window on the
compressor accessory plug cord.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-38.
