2003 BUICK PARK AVENUE service interval reset

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
®ve seconds. After ®ve seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear on the
display after about ®ve seconds, see your dealer for
service. After you release the DIC RESET button,
TIRE PRESSURE NORMAL will appear on 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
(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
When It Is Time
for New Tires on page 5-63andWheel Replacement
on page 5-66for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See ªPart A: Scheduled
Maintenance Services,º in Section 6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the Tire-Loading
Information label.

Footnotes
²The 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.
*If your vehicle has the GM Oil Life System, a computer
system lets you know when to change the engine oil
and ®lter. This is based on engine revolutions and
engine temperature, and not on mileage. Basedon driving conditions, the mileage at which an oil
change will be indicated can vary considerably. For the
oil life system to work properly, you must reset the
system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL SOON message
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
®lter must be changed at least once a year and at
this time the system must be reset. It is also important
to check your oil regularly and keep it at the proper
level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil on
page 5-14
for information on resetting the system.
Whenever the tires are rotated, the Check Tire Pressure
System (if equipped) must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-24.
