A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle’s
original equipment tires and
the correct inflation pressure for
your vehicle’s tires when they
are cold. See Loading the Vehicle
on page 4-16, for an example of the
Tire and Loading Information
label and its location on your
vehicle. Also see Inflation - Tire
Pressure on page 5-42.
Your vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
and Rotation on page 5-48 and Tires
on page 5-36.
Notice: Using non-approved tire
sealants 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 the GM approved tire
sealant available through your
dealer/retailer.
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 5-57 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.
