Compass Calibration

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not use magnetic tools when servicing the overhead console.

The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or out of calibration, perform the following calibration procedure.

NOTE: Whenever the compass is calibrated manually, the variance number must also be reset.

NOTE: If the "CAL" message remains in the display, either there is excessive magnetism near the compass, or the unit is faulty. Repeat the calibration procedure one more time.

NOTE: If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat the calibration procedure in another location.

Turn the ignition switch to the ON position. If the compass/thermometer data is not currently being displayed, momentarily depress and release the C/T push button to reach the compass/thermometer display.
Depress the reset push button and hold the button down until "CAL" appears in the display. This takes about 10 seconds, and appears about 5 seconds after "VARIANCE = XX " is displayed.
Release the Reset push button.
Drive the vehicle on a level surface, away from large metal objects and power lines, through 3 or more complete circles at between 3-5 MPH (5-8 KM/H) in not less than 48 seconds. The "CAL" message will disappear from the display to indicate that the compass is now calibrated.
