When a low tire pressure condition is
detected, the TPMS illuminates the
low tire pressure warning light
located on the instrument panel
cluster.
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 3-45 or DIC Operation and
Displays (Without DIC Buttons) on
page 3-50 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 the Vehicle
on page 4-18, for an example of the
Tire and Loading Information
label and its location on your
vehicle. Also see Inflation - Tire
Pressure on page 5-45.
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 5-52 and Tires on page 5-39.
Notice: Using non-approved tire
sealants could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use the
GM approved tire sealant available
through your dealer/retailer.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 5-62 for
information regarding the inflator kit
materials and instructions.
