necessary until the desired variance is achieved.
NOTE: The factory default zone is 8. During program-

Manual Compass Calibration
If the compass appears erratic, inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-

1. Start the engine and leave the transmission in the
PARK position.
2. Push and hold the RESET button (for approximately
10 seconds) until the current variance zone number is

3. Release the RESET button, then push and hold again
for approximately 10 seconds, until the direction is
displayed, with the CAL indicator on continuously in
the display.
4. To complete the compass calibration, drive the vehicle
in one or more complete 360–degree circles, under
5 mph (8 km/h) in an area free from power lines and
large metallic objects, until the CAL indicator turns
off. The compass will now function normally.
NOTE:
• A good calibration requires a level surface and an
environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.
• Magnetic materials should be kept away from the top
of the center of the instrument panel. This is where the
compass sensor is located.
