Your vehicle’s TPMS system can warn you about a
low tire pressure condition but it does not replace
normal tire maintenance. See Tire Inspection and
Rotation on page 398 and Tires on page 385.
Notice: Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
If the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM will be shown on the DIC
display. If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message will be displayed. Once you re-install the
TPMS sensors, the error message should go
off. See your GM dealer for service if all TPMS
sensors are installed and the error message
comes on and stays on.
Resetting the TPMS Sensor
Identification Codes
Each TPMS sensor has a unique identification
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identification 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 inflation
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, or more than
five minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.
