the top of the right rear quarter window. This is where
the compass sensor is located.
To Set the Variance
Start the engine, and leave the transmission in the P
(Park) position. Press and hold (approximately ten sec-
onds) the odometer/trip odometer reset button until the
current variance zone number is displayed. To change the
zone, press and release the odometer/trip odometer reset
button to increment 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.
Compass Calibration
If the compass appears erratic, inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-
ing the compass make sure the proper zone is selected.
