Tire Inspection And Rotation - Buick 2003 LeSabre Owner's Manual

Don't reset the check tire pressure system without first
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.
To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display
will show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear in the display
after about five seconds retry the process. If it
does not work after two tries, see your dealer for
service. After you release the DIC RESET button,
TIRE PRESSURE NORMAL will appear in the
display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system has
been calibrated, the system will alert the driver that a tire
is low, up to a maximum speed of 65 mph (105 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(1 0 000 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 5-65 and Wheel Replacement on
page 5-68for 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 "Part A: Scheduled
Maintenance Services," in Section 6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
