Tire Inspection And Rotation - Cadillac DeVille 2005 Owner's Manual

The TPM system also allows the driver to check the air
pressure status of each road tire using the Driver
Information Center (DIC). Each tire's air pressure will be
listed individually, in the following order: LF (left front
or driver's side front tire), RF (right front or passenger's
side front tire), RR (right rear or passenger's side
rear tire) and LR (left rear or driver's side rear tire). See
Inflation - Tire Pressure on page 5-65 for information
regarding correct tire inflation. Also, see Driver
Information Center (DIC) on page 3-57 for information
on the DIC controls and displays.
If the DIC display does not show tire pressures or the
SERVICE TPM SYSTEM message appears, see
your dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires, the TPM system will need to be reset. A special
tool is needed to reset the sensor identification
codes. See your dealer for service.
Your vehicle was delivered from the factory with
aluminum valve stem caps. If you ever have to replace
the valve stem caps on your vehicle, you should
replace them with aluminum or plastic caps.
The TPM system can alert you about a low or high tire
pressure condition, but it does not replace normal
tire maintenance. See Tires on page 5-57.

Tire Inspection and Rotation

Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See When It Is Time
for New Tires on page 5-70 and Wheel Replacement
on page 5-73 for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See Scheduled Maintenance
on page 6-4.
When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the compact spare tire, if your vehicle
has one, in your tire rotation.
