with the door open or the remote keyless entry
transmitter. The security light should come on
and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.

Resetting the TPMS Sensor
Identication Codes
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors,
rotate the vehicle’s tires, or install a full-size spare
that has a TPMS sensor, the sensor’s identication
codes will need to be matched to the new tire/wheel
position. Each tire/wheel position is matched to
the TPMS sensor 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 air pressure,
do not exceed the maximum tire pressure indicated on
the tire’s sidewall.
You will have two minutes to match the rst tire/wheel
position, and ve minutes overall, to match all
four tire/wheel positions. If it takes longer than
two minutes, to match the rst tire and wheel, or
more than ve minutes to match all four tire and wheel
positions 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. Press the Driver Information Center (DIC) vehicle
information button until the RELEARN TIRE
POSITIONS displays.
4. Press the set/reset button to allow the system to
learn the tire positions. The horn will sound twice
to indicate that the TPMS is ready, and then
the message TIRE LEARNING ACTIVE will display.
The sensor matching process can begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the 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, conrms that the
sensor identication code has been matched to
this tire 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.
