After any replacement or the appearance of a "locked-up" condition, you must calibrate the compass. Follow these instructions in order to ensure correct compass calibration:
- Drive the vehicle to an area away from any large metal objects or overhead power lines.
- Ensure that the proper variance zone is selected. See "SETTING MAGNETIC ZONE VARIANCE ".
- With the engine running, depress and hold the STEP button for 10 - 15 seconds.
- ZONE will appear in display, then CAL.
- Release the STEP button within 2 seconds of CAL illuminating.
- CAL is displayed.
- Drive slowly, less than 5 MPH (8 KPH) in 3 complete 360 degree circles.
- CAL will stay illuminated to alert the driver that the Compass/Temperature Module is in the calibration mode.
- After calibration, the CAL will turn off.
