Tire Pressure Monitor Operation - Cadillac CTS-V 2009 Owner's Manual

Tire Pressure Monitor Operation

This vehicle may have a Tire Pressure Monitor System
(TPMS). 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, if the vehicle has one.
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.
Using the Driver Information Center (DIC), the driver
can also check tire pressure levels using the DIC.
For additional information and details about the DIC
operation and displays see DIC Operation and Displays
on page 3-51 and DIC Warnings and Messages on
page 3-58.
A DIC warning message to check the pressure in a
specific tire is also shown on the DIC display screen.
The low tire pressure warning light and the DIC warning
message come 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.
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.
The 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 the
tires when they are cold. See Loading the Vehicle on
page 4-20, for an example of the Tire and Loading
Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 5-69.
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: 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.
Your vehicle, when new, included a factory-installed
Tire Inflator Kit. This kit uses a GM approved liquid
tire sealant. Using non-approved tire sealants could
damage the TPMS sensors. See Tire Sealant and
Compressor Kit on page 5-86 for information regarding
the inflator kit materials and instructions.
