10-50 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 10‑52, Tire
Rotation on page 10‑53 and Tires
on page 10‑39.
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.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑64 for
information regarding the inflator kit
materials and instructions.
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 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 low tire warning
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, if your vehicle has one.
The spare tire does not have
a TPMS sensor. The TPMS
malfunction light and DIC
message should go off once
you re‐install the road tire
containing the TPMS sensor.
.
The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle's tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process
is performed successfully.
See “TPMS Sensor Matching
Process” later in this section.
.
One or more TPMS sensors
are missing or damaged. The
DIC message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer
for service.
