compass has been calibrated , the CAL sym bol will turn
off and the compass will function norm ally.
Com pass Variation Adjustm ent
Com pass Variance is the difference betw een magnetic
north and geograp hic north. In som e areas of the country,
the difference betw een magnetic and geograp hic north is
great enou gh to cause the compass to give false read ings.
If this occurs, the compass variance must be set accord ing
to the Com pass Variance Map .
Manual Calib ration
If the compass appears erratic and CAL does not appear,
you must manu ally put the compass into the calibration
mode. To ensu re prop er compass calibration, make sure
the compass variance is prop erly set before manu ally
calibrating the compass (refer to Com pass Variation
Adjustm ent).
NOTE: When the mirror is in the VAR mode, the letter
“Z” will be displayed along with the currently selected
zone nu mber.
To put the compass into calibration mode: Turn the
ignition to the ON position. Press and hold the center
button for more than 6 second s until CAL (calibration
mode) appears in the display. To change the display
betw een VAR (compass variance) and CAL (compass
calibration) modes. Release the button to invoke manu al
calibration mode. To recalibrate the compass, drive the
vehicle at less than 5 mph (8 km/ h) throu gh up to CAL
