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. 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 will illuminate
the low tire pressure warning
symbol 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 loading
information label. See Vehicle Load
Limits in the owner manual for
more information.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). 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.
For additional information and
details about the DIC operation and
displays see Driver Information
Center (DIC) on page 5 11.
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.

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 for an example of the Tire
and Loading Information label and
its location. Also see Tire Pressure
on page 10 18.
The TPMS can warn about a
low tire pressure condition but it
does not replace normal tire
maintenance. See Tire Inspection,
Tire Rotation and Tires in the
owner manual for more information.
Notice: 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.
