Pontiac 2004 Bonneville - Manual (Page 346)

To reset (calibrate) the system with a systems monitor:
1. Turn the ignition switch to ON.
2. Press and hold the TIRE PRESS RESET button for
about five seconds.
3. The TIRE PRESS light on the systems monitor
should begin to flash. If the TIRE PRESS light
does not begin to flash after about five seconds, see
your dealer for service.
4. Release the TIRE PRESS RESET button and the
system should reset. The TIRE PRESS light will
go out.
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 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 5-72 and Wheel Replacement
on page 5-75 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 Part A: Scheduled
Maintenance Services on page 6-4, for scheduled
rotation intervals.
