Vehicle Care
If the hazard warning flashers are on, the
tire fill alert visual feedback will not work
properly.
The TPMS will not activate the tire fill alert
properly under the following conditions:
.
There is interference from an external
device or transmitter.
.
The air pressure from the inflation device
is not sufficient to inflate the tire.
.
There is a malfunction in the TPMS.
.
There is a malfunction in the horn or turn
signal lamps.
.
The identification code of the TPMS
sensor is not registered to the system.
.
The battery of the TPMS sensor is low.
If the tire fill alert does not operate due to
TPMS interference, move the vehicle about
1 m (3 ft) back or forward and try again.
If the tire fill alert feature is not working,
use a tire pressure gauge.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification code
needs to be matched to a new tire/wheel
position after rotating the vehicle
’
s tires or
replacing one or more of the TPMS sensors.
The TPMS sensor matching process should
also be performed after replacing a spare
tire with a road tire containing the TPMS
sensor. The malfunction light and the DIC
message should go off at the next ignition
cycle. The sensors are matched to the tire/
wheel positions, using a TPMS relearn tool,
in the following order: driver side front tire,
passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for
service or to purchase a relearn tool.
A TPMS relearn tool can also be purchased.
See Tire Pressure Monitor Sensor Activation
Tool at www.gmtoolsandequipment.com or
call 1-800-GM TOOLS (1-800-468-6657).
There are two minutes to match the first
tire/wheel position, and five minutes overall
to match all four tire/wheel positions. If it
takes longer, the matching process stops
and must be restarted.
The TPMS sensor matching process is:
1. Set the parking brake.
2. Place the vehicle in Service Mode. See
.
3. Make sure the Tire Pressure info page
option is turned on. The info pages on
the DIC can be turned on and off
through the Options menu. See
Information Center (DIC) (Base Level)
or
Driver Information Center (DIC) (Uplevel)
.
4. Use the DIC controls on the right side of
the steering wheel to scroll to the Tire
Pressure screen under the DIC info page.
5. Press and hold
V
in the center of the
DIC controls.
The horn sounds twice to signal the
receiver is in relearn mode and the TIRE
LEARNING ACTIVE message displays on
the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire
sidewall, near the valve stem. Then press
the button to activate the TPMS sensor.
A horn chirp confirms that the sensor
identification code has been matched to
this tire and wheel position.
8. Proceed to the passenger side front tire,
and repeat the procedure in Step 7.
9. Proceed to the passenger side rear tire,
and repeat the procedure in Step 7.
10. Proceed to the driver side rear tire, and
repeat the procedure in Step 7. The horn
sounds two times to indicate the sensor
