UNDERSTANDING YOUR INSTRUMENT PANEL 255 To Set the Variance Start the engine and leave the transmission gear selector lever in the PARK position. Press and hold the CMTC reset button (for approximately ten seconds) until the current variance zone number is displayed. To change the zone, press and release the CMTC reset button to increase the variance one step. Repeat as necessary until the desired variance is achieved. NOTE: The factory default zone is 8. During programming, the zone value will wrap around from zone 15 to zone 1. Manual Compass Calibration If the compass appears erratic or inaccurate, and the variance has been properly set, you may wish to manually recalibrate the compass. To manually calibrate the compass: 1. Start the engine and leave the transmission in the PARK position. 2. Press and hold the CMTC reset button (for approximately 10 seconds) until the current variance zone number is displayed. 3. Release the CMTC reset button, then press 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. 4
