air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9-9, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10-35.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Tire Inspection
on page 10-39, Tire Rotation on
page 10-39 and Tires on
page 10-26.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage

caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. The malfunction
light comes on at each ignition cycle
until the problem is corrected. Some
of the conditions that can cause
these to come on are:
One of the road tires has been
replaced with the spare tire. The
(Continued) spare tire does not have a
TPMS sensor. The malfunction
light should go off after the road
tire is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light should go off
after successfully completing the
sensor matching process. See
"TPMS Sensor Matching
Process" later in this section.
One or more TPMS sensors are
missing or damaged. The
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
