Tire Pressure Monitor Operation - Hummer 2008 H2 Owner's Manual

Tire Pressure Monitor Operation

The Tire Pressure Monitor System (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 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. Using the DIC, tire pressure levels can be
viewed by the driver. For additional information

When a low tire pressure
condition is detected,
the TPMS illuminates
the low tire pressure
warning light located on
the instrument panel
cluster.
and details about the DIC operation and displays see
DIC Operation and Displays (Using DIC Buttons)
on page 3-49 or DIC Operation and Displays (Using Trip
Odometer Reset Stem) on page 3-54 and DIC
Warnings and Messages on page 3-56.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. See Loading
Your Vehicle on page 4-44, for an example of the Tire
and Loading Information label and its location on
your vehicle. Also see Inflation - Tire Pressure on
page 5-61.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. See Tire Inspection and Rotation on
page 5-67 and Tires on page 5-55.
Notice: Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
