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
ļ¬ashes 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:
ā¢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 TPMS malfunction
light and DIC message should go off once you
re-install the road tire containing the TPMS sensor.
ā¢The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicleās tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See āTPMS Sensor Matching Processā later in this
section.
ā¢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.
ā¢Replacement tires or wheels do not match your
vehicleās 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 6-64 .
ā¢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 identiļ¬cation code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicleās tires, the identiļ¬cation 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/retailer for
service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tireās
air pressure. When increasing the tireās pressure, do
not exceed the maximum inļ¬ation pressure indicated on
the tireās sidewall. To decrease the tireās 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 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.
TPMS Matching Process for Vehicles
with Remote Keyless Entry (RKE)
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with theengine off.
3. Press and hold the Remote Keyless Entry (RKE) transmitterās lock and unlock buttons, at the same
time, for about ļ¬ve 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
cornerās sensor is ready to be learned.
5. Remove the valve cap from the tireās valve stem. Activate the TPMS sensor by increasing or
decreasing the tireās 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 ļ¬ash one time to conļ¬rm the sensor
identiļ¬cation 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.

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 speciļ¬ed
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 signiļ¬cantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction ā AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the tireās
ability to stop on wet pavement as measured
under controlled conditions on speciļ¬ed
government test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
