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 program-
ming, 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 manu-
ally 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 approxi-
mately 10 seconds) until the current variance zone num-
ber 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.
