Tire Pressure Monitor Operation - Chevrolet 2008 Avalanche 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 and details about the
DIC operation and displays see DIC Operation and
Displays (With DIC Buttons) on page 3-51 or DIC
Operation and Displays (Without DIC Buttons) on
page 3-56 and DIC Warnings and Messages on
page 3-59.
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 4-36, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 5-64.
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 5-70 and Tires on page 5-56.
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.
