Tire Pressure Monitor Operation

This vehicle may have a Tire Pressure
Monitor System (TPMS). The TPMS is
designed to warn the driver when a low tire
pressure condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire and
wheel assembly. The TPMS sensors monitor
the air pressure in the tires and transmit the
tire pressure readings to a receiver located
in the vehicle.
When a low tire pressure condition is
detected, the TPMS illuminates the low tire
pressure warning light located on the
instrument cluster. If the warning light
comes on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the Tire and Loading
Information label. See Vehicle Load Limits
0 191.
A message to check the pressure in a
specific tire may display in the Driver
Information Center (DIC). The low tire
pressure warning light and the DIC warning
message, if equipped, come on at each
ignition cycle until the tires are inflated
to the correct inflation pressure. Using the
DIC, it may be possible to view the tire
pressure levels. For additional information
and details about the DIC operation and
displays, see Driver Information Center (DIC)
(Base Level) 0 108 or
Driver Information Center (DIC) (Uplevel)
0 110.
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.
Vehicle Care
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
0 191, for an example of the Tire and
Loading Information label and its location.
Also see Tire Pressure 0 291.
The TPMS can warn about a low tire
pressure condition, but it does not replace
normal tire maintenance. See Tire Inspection
0 296, Tire Rotation 0 296, and Tires 0 285.
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 pressure warning
light, defined above, flashes for about
one minute and then stays on for the
