shown on the Tire and Loading
Information label. See Vehicle Load
Limits 0 181.
The low tire pressure warning light
comes on at each ignition cycle until
the tires are inflated to the correct
inflation pressure.
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 Vehicle Load
Limits 0 181, for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0 260.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Tire Inspection
0 265, Tire Rotation 0 265 and Tires
0 253.
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
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 ignition cycle. The malfunction
light comes on at each ignition cycle
until the problem is corrected. Some
of the conditions that can cause this
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 should go off after the road
tire is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.
.
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light should go off
after successfully completing the
sensor matching process. See
"TPMS Sensor Matching
Process" later in this section.
.
One or more TPMS sensors are
missing or damaged. The
malfunction light should go off
when the TPMS sensors are
installed and the sensor
