Tire Pressure Monitor Operation - Cadillac 2008 XLR 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 on your vehicle. 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 appear at each ignition
cycle until the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can

light, located in the

be viewed by the driver. For additional information and
details about the DIC operation and displays see
DIC Operation and Displays on page 3-60 and DIC
Warnings and Messages on page 3-63.
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 5-22, for an example of the
Tire and Loading Information label and its location on
your vehicle. Also see Inflation - Tire Pressure on
page 6-60 for additional information.
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 6-65, When It Is Time for New Tires on page 6-66,
and Tires on page 6-52.
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.
