10-56 Vehicle Care
Your vehicle's TPMS can warn you
about a low tire pressure condition,
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10 58, Tire Rotation on
page 10 59, and Tires on
page 10 44.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (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. A DIC warning
message is also displayed. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause the malfunction light and DIC
message to come on are:
One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off once you re-install
the road tire containing the
TPMS sensor 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 vehicle's tires. The
malfunction light and the DIC
message 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 and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See
your dealer for service.
