The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. 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,
attached to your vehicle, shows the
size of the original equipment tires
and the correct inflation pressure for
the tires when they are cold. See

example of the Tire and Loading
Information label and its location.

Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS

caused by using an incorrect tire
sealant is not covered by the

the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light and

The TPMS will not function properly if

missing or inoperable. When the
system detects a malfunction, the low

ignition cycle until the problem is
corrected. Some of the conditions that
can cause these to come on are:

DIC message should go off after the
road tire is replaced and the sensor
matching process is performed

section.

The TPMS sensor matching process
was not done or not completed

successfully completing the sensor
matching process. See "TPMS
