Compass Calibration

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 the Electronic Vehicle Information Center (EVIC) displays "CAL", perform the following calibration procedure. Also, any time EVIC service replacement components are installed, they must be calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

Calibrate the compass manually as follows:

1. Turn the ignition switch to the On position.
2. Depress and hold the C/T push button (3) for approximately two seconds.

3. Use the SCROLL buttons (3) until MANUAL COMPASS CALIBRATION is highlighted.
4. Press and release the FUNCTION SELECT button (1) to start the calibration. The message "CAL" will appear in the EVIC display.
5. Drive the vehicle on a level surface, away from large metal objects and power lines, through one or two complete  circles in not less than 16 seconds. The "CAL" message will disappear from the display to indicate that the compass is now calibrated.
