This could be an early indicator that
the air pressure is getting low and
needs to be inflated to the proper
pressure.
The 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 9‑12, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑74.
The TPMS can warn about a
low tire pressure condition but it
does not replace normal tire
maintenance. See Tire Inspection
on page 10‑80, Tire Rotation on
page 10‑81 and Tires on
page 10‑66.
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 10‑91
for information regarding the inflator
kit materials and instructions.

remainder of the ignition cycle.
A DIC warning message also
displays. 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 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. The malfunction light
