Factory-installed Tire Inflator Kits use a GM approved
liquid tire sealant. Using non-approved tire sealants
could damage the TPMS sensors. SeeTire Sealant and
Compressor Kit
on page 6‑70for information regarding
the inflator kit materials and instructions.
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until
the problem is corrected. Some of the conditions that
can cause the malfunction light and DIC message to
come on are:
.One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re‐install the road
tire containing the TPMS sensor.
.The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle's tires. The DIC message
and TPMS malfunction light should go off once the
TPMS sensor matching process is performed
successfully. See “TPMS Sensor Matching
Process” later in this section.
.One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your dealer
for service.
.Replacement tires or wheels do not match your
vehicle's original equipment tires or wheels. Tires
and wheels other than those recommended for
your vehicle could prevent the TPMS from
functioning properly. See Buying New Tires
on
page 6‑62.
.Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer for service if the
TPMS malfunction light and DIC message comes on
and stays on.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle's tires, the identification codes
need to be matched to the new tire/wheel location. The
sensors are matched, to the tire/wheel locations, in the
following order: driver side front tire, passenger side
front tire, passenger side rear tire, and driver side rear
tire using a TPMS diagnostic tool. See your dealer for
service.
The TPMS sensors can also be matched to each tire/
wheel position by increasing or decreasing the tire's air
pressure. When increasing the tire's pressure, do not
exceed the maximum inflation pressure indicated on the
tire's sidewall. To decrease the tire's air-pressure use
the pointed end of the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match each tire and wheel
position. If it takes longer than two minutes to match
any tire and wheel position, the matching process stops
and you need to start over.
The TPMS matching process is outlined below:1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off. 3. Press and hold the Remote Keyless Entry (RKE)
transmitter's LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the
TPMS learn mode. The horn sounds twice
indicating the TPMS receiver is ready and in
learn mode.
4. Start with the driver side front tire. The driver side front turn signal also comes on to indicate that
corner's sensor is ready to be learned.
5. Remove the valve cap from the tire's valve stem. Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to the
tire/wheel position.
6. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and repeat
the procedure in Step 5.
7. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and repeat
the procedure in Step 5.

GM's exclusive TPC Spec system considers over
a dozen critical specifications that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM's TPC Spec number is molded
onto the tire's sidewall near the tire size. If the
tires have an all‐season tread design, the TPC
Spec number will be followed by an MS for mud
and snow. SeeTire Sidewall Labeling
on
page 6‑48
for additional information.
GM recommends replacing tires in sets of four.
This is because uniform tread depth on all tires
will help keep your vehicle performing most like it
did when the tires were new. Replacing less than
a full set of tires can affect the braking and
handling performance of your vehicle. See Tire
Inspection and Rotation
on page 6‑60for
information on proper tire rotation.
{WARNING:
Tires could explode during improper service. You
or others could be injured or killed if you attempt
to mount or dismount a tire. Only your dealer or
an authorized tire service center should mount
and dismount the tires.
{WARNING:
Mixing tires could cause you to lose control
while driving. If you mix tires of different
sizes, brands, or types (radial and
bias-belted tires), the vehicle may not handle
properly, and you could have a crash. Using
tires of different sizes, brands, or types may
also cause damage to your vehicle. Be sure
to use the correct size, brand, and type of
tires on all wheels. It is all right to drive with
your compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire
on page 6‑91.

All Passenger Car Tires Must Conform to Federal
Safety Requirements In Addition To These
Grades.
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 (1½) 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. Warning: The traction grade
assigned to this tire is based on straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning, or peak
traction characteristics.
Temperature
–A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law. Warning: The
temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure.

A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blowout remove your foot from
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road, if possible.
{WARNING:
Driving on a flat tire will cause permanent damage
to the tire. Re-inflating a tire after it has been
driven on while severely under-inflated or flat may
cause a blowout and a serious crash. Never
attempt to re-inflate a tire that has been driven on
while severely under-inflated or flat. Have your
dealer or an authorized tire service center repair
or replace the flat tire as soon as possible.
{WARNING:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a
jack is provided with the vehicle, it is designed
only for changing a flat tire. If it is used for
anything else, you or others could be badly
injured or killed if the vehicle slips off the jack. If a
jack is provided with the vehicle, only use it for
changing a flat tire.
This vehicle may come with a jack and spare tire or a
tire sealant and compressor kit. To use the jack and
spare tire, see Changing a Flat Tire
on page 6‑78.
To use the tire sealant and compressor kit, see Tire
Sealant and Compressor Kit
on page 6‑70.
