Compass Calibration
COMPASS CALIBRATION
The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass
calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle
may acquire during normal use. If the compass readings appear to be erratic or out of calibration, perform the following calibration procedure. Also, new
service replacement compass/temperature mirrors must have their compass calibrated using this procedure. Do not attempt to calibrate the compass near
large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.
FIRST TIME COMPASS CALIBRATION
The mirror is shipped in the first time calibration mode with the CAL symbol illuminated. After completing three 360° turns in an area free from large
metal objects, the CAL symbol should turn off and the compass will function normally.
MANUAL COMPASS CALIBRATION
1. Press and hold the Zone/Calibration (left reading lamp button) button for 10 to 15 seconds. This will toggle the CAL mode on/off, causing the
CAL symbol to illuminate/darken respectively.
2. Release the button once the CAL symbol illuminates/darkens. Manual compass calibration has been initiated at this point.
3. Drive the vehicle in circles in an area free from large metal objects until the CAL symbol is no longer displayed.
When the CAL symbol is no longer displayed, the compass is calibrated and should display correct headings. Verify proper calibration by checking
North (N), South (S), East (E), and West (W). If the compass does not appear accurate, repeat the calibration procedure in another area.
NOTE:
-
If the "CAL" message remains in the display, either there is excessive magnetism near the compass, or the unit is faulty. Repeat the calibration
procedure at least one more time.
-
If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat
the calibration procedure in another location.
