Cadillac 2006 XLR Owner's Manual page 372

You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle's tire information placard.
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability.
Each tire, including the spare, should be checked monthly
when cold and set to the recommended inflation pressure
as specified in the vehicle placard and owner's manual.
The Tire and Loading Information Label (tire information
placard) is on the rear edge of the driver's door, below the
door latch. This label shows the size of your vehicle's
original tires and the correct inflation pressure for your
vehicle's tires when they are cold. See Loading Your
Vehicle on page 5-33.
Your vehicle's TPM system can alert you about a low or
high tire pressure condition but it does not replace
normal tire maintenance. See Tire Inspection and
Rotation on page 6-57

When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
Each TPM sensor has a unique identification code that
is matched to one of the four tire positions on your
vehicle. The tire and wheel assembly positions are,
left front (LF); right front (RF); right rear (RR) and left
rear (LR). Any time you rotate your vehicle's tires
or replace one or more TPM sensors, the identification
codes will need to be matched to the new tire and
wheel position. The TPM matching process is performed
in a specific sequence and time limit. A special tool is
also required. See your dealer for service.
The SVC TIRE MONITOR message is displayed when
the TPM system is malfunctioning. For example,
one or more TPM sensors may be inoperable or
missing. See your dealer for service.
