Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. See Tire Inspection and
Rotation on page 409 and Tires on page 392.
Notice: Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
Resetting the TPMS Identification
Codes
Each TPMS sensor has a unique identification
code. Any time you replace one or more of the
TPMS sensors or rotate the tires, the identification
codes will need to be matched to the new tire and
wheel position. The sensors are matched to the tire
and 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 and wheel position by increasing or decreasing
the tire’s air pressure. When increasing tire
pressure do not exceed the maximum inflation
pressure indicated on the tire’s sidewall.
You will have two minutes to match the first tire
and wheel position, and five minutes overall
to match all four tire and 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 will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Using the Remote Keyless Entry (RKE)
transmitter, lock and unlock the vehicle’s
doors.
4. Press the lock and unlock buttons, at the same
time, on the RKE transmitter. A single horn
chirp will sound, indicating that the TPMS
system is ready, and the sensor matching
process can begin.
5. Start with the driver’s side front tire.
