service interval reset BUICK CENTURY 2002 Owner's Manual

6-44
To reset (calibrate) the system:
1. Turn the ignition to RUN.
2. Locate the red RESET button inside of your
instrument panel fuse block.
The fuse block is located under the cover labeled
FUSES, which is at the end of the instrument panel on
the passenger's side of the vehicle. The RESET button
is the first button in the top row of the fuse block.
3. Press and hold the RESET button for about
five seconds.
The LOW TIRE light will come on and flash three
times. Then it will go off. If the light doesn't go off,
see your dealer for service.
The system completes the calibration process during driving.
The system normally takes 15 to 20 minutes of driving in
each of three speed ranges to ªlearnº tire pressures. The
speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to
65 mph (65 to 105 km/h) and above 65 mph (105 km/h).
When learning is complete, the system will alert you after
two to eight minutes if a tire is 12 psi (83 kPa) different
from the other three tires. Detection thresholds may be
higher and detection times may be longer on rough roads,
curves and at high speeds. The system is not capable of
detection at speeds greater than 70 mph (110 km/h).Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 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 ªWhen It's Time for New Tiresº and ªWheel
Replacementº later in this section 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 ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.

Scheduled Maintenance
7-5
The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown at 150,000 miles
(240 000 km) should be repeated at the same
interval after 150,000 miles (240 000 km) for the
life of this vehicle.
See ªOwner Checks and Servicesº and ªPeriodic
Maintenance Inspectionsº following.Footnotes

The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that
the failure to perform this maintenance item will not
nullify the emission warranty or limit recall liability
prior to the completion of the vehicle's useful life.
We, however, urge that all recommended maintenance
services be performed at the indicated intervals and
the maintenance be recorded.
@ Whenever the tires are rotated, the Tire Inflation
Monitor System must be reset.
+ A good time to check your brakes is during tire
rotation. See ªBrake System Inspectionº under
ªPeriodic Maintenance Inspectionsº in Part C of
this schedule.
