Tire Pressure Monitor Operation - Chevrolet 2009 Suburban Owner's Manual

Tire Pressure Monitor Operation

If your vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
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 vehicle's tires and transmit
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.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light
located on the instrument
panel cluster.
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 3-52 or DIC
Operation and Displays (Without DIC Buttons) on
page 3-58 and DIC Warnings and Messages on
page 3-64.
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 the
Vehicle on page 4-33, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also see Inflation - Tire Pressure on page 5-70.
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 5-76 and Tires on page 5-61.
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.
