Re-calibrating the Compass.
There are some conditions that can
cause changes to the vehicle's magnetic
field. Items such as installing a ski rack or
a CB antenna or even some body repair
work on the vehicle can cause changes
to the vehicle's magnetic field. In these
situations, the compass will need to be
re-calibrated to quickly correct for these
changes. To re-calibrate the compass:
1. Press and hold the button (2) between
9 and 12 seconds. Release the button
when a "C" appears in the display,
which indicates the compass needs
calibration.
2. To re-calibrate the compass, drive the
vehicle is 2 complete circles at less
than 5 MPH.
