tires are inflated to the correct
inflation pressure. Using the DIC,
tire pressure levels can be viewed.
For additional information and
details about the DIC operation and
displays see Driver Information
Center (DIC) 0 96.
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 must
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 Tire Pressure
0 314, for an example of the Tire
and Loading Information label and
its location. Also see Wheels and
Tires 0 268.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Wheels and Tires
0 268 and
Tire Rotation 0 274.
Caution
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.
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 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. The
spare tire does not have a
TPMS sensor. The malfunction
light and DIC message should
go off after the road tire is
replaced. See "TPMS Sensor
Calibration Process" later in this
section.
The TPMS sensor calibration
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor calibration process. See
"TPMS Sensor Calibration
Process" later in this section.
One or more TPMS sensors are
missing or damaged. The DIC
message and the malfunction
light should go off when the
TPMS sensors are installed and
