Dodge 2009 Caravan - Manual (Page 253)

NOTE: Magnetic and battery powered devices, (such as
cell phones, IPOD’s, radar detectors, PDA’s and laptops)
should be kept away from the top of the instrument
panel. This is where the compass module is located and
such devices may interfere and cause false compass
readings.
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 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.
