10-58 Vehicle Care
This could be an early indicator that
the 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 14, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10 54.
The TPMS can warn about
a low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10 61, Tire Rotation on
page 10 61, and Tires on
page 10 48.
Notice: 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.
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 71 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 pressure warning light
flashes for about one minute and
then stays on for the remainder
of the vehicle on/off cycle. A DIC
warning message also displays.
The malfunction light and DIC
warning message come on at
each vehicle on/off 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, if the vehicle has one.
The spare tire does not
have a TPMS sensor.
