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, if the
vehicle has one. The spare tire
does not have a TPMS sensor.
The DIC message should go off
once you re-install the road tire
containing the TPMS sensor.
•The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle’s tires.
The DIC message should go
off after successfully completing
the sensor matching process.
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/
retailer 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. SeeBuying
New Tires on page 9-63.
•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/retailer 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 your vehicle’s tires,
the identification codes need to be
matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions 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/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air 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
gage, or a key.You have two minutes to match
the first tire/wheel position, and
five minutes overall, to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the first tire and wheel, or more than
five minutes to match all four tire
and wheel positions, 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. Go to the TPM vehicle
information screen on the DIC.
SeeDriver Information Center
(DIC) on page 4-27. Press set to
relearn the sensors. The horn
sounds twice to signal the
receiver is in relearn mode and
Tire Learning Active message
displays on the DIC screen.
4. Start with the driver side
front tire.5. Remove the valve cap from
the valve stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for 10 seconds, or until a horn
chirp sounds. The horn chirp,
which can take up to 30 seconds
to sound, confirms that the TPMS
sensor identification code has
been matched to this tire position.
6. Proceed to the passenger
side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger
side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5.
9. After hearing the confirming horn
chirp, for the driver side rear tire,
the horn sounds two more times
to signal the tire learning mode is
no longer active. Turn the ignition
switch to LOCK/OFF.
9-60 Vehicle Care

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.
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.
