Tire Pressure Monitor Operation - GMC Sierra 2010 Owner's Manual

When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
See Tire Pressure Monitor Operation on page 6 76 for
additional information.

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
6-76
monitor the air pressure in the vehicle's tires and
transmits the tire pressure readings to a receiver
located in the vehicle.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message come on at each ignition
cycle until the tires are inflated to the correct inflation
pressure. If your vehicle has DIC buttons, tire pressure
levels can be viewed by the driver. For additional
information and details about the DIC operation and
displays see DIC Operation and Displays (With DIC
Buttons) on page 4 51 or DIC Operation and Displays
(Without DIC Buttons) on page 4 58 and DIC Warnings
and Messages on page 4 65.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
symbol located on the
instrument panel cluster.
