TPMS Sensor Identi cation Codes
Each TPMS sensor has a unique identi cation code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle’s tires, the identi cation codes
will need to be matched to the new tire/wheel position.
The sensors are matched, to the tire/wheel positions,
in the following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool. See
your GM dealer for service.
The TPMS sensors may 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 in ation pressure indicated on
the tire’s sidewall.
You will 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 will need to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Using the DIC, press the vehicle information
button until the LEARN TIRE POSITIONS message
displays.
4. Press the set/reset button to allow the system to
learn the tire positions. The horn will sound twice
to indicate the receiver is ready, and the TIRE
LEARNING ACTIVE message will display. The
TPMS system is ready for the sensor matching
process to begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the tire’s 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 the tire/wheel position. To decrease the tire’s
air-pressure use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-67andWheel Replacement
on page 5-71for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4for scheduled rotation intervals.When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front and
rear in ation pressures as shown on the Tire and
Loading Information label. SeeIn ation - Tire Pressure
on page 5-60andLoading Your Vehicle on page 4-29.
Reset the Tire Pressure Monitor System. See “TPMS
Sensor Identi cation Codes” underTire Pressure
Monitor System on page 5-62.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Speci cations on page 5-100.
