3. Keep pressing the COMP button until the desired
zone number appears in the display. Release the
button. After about four seconds of inactivity,
the new zone number will be locked in and the
comp/temp display will return.
4. Calibrate the compass as described below.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If after five seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
press the COMP button for approximately 12 seconds
or until CAL is displayed.
The compass can be calibrated in one of two ways:
Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or
drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.
Cleaning the Mirror
Use a paper towel or similar material dampened with
glass cleaner. Do not spray glass cleaner directly on the
mirror as that may cause the liquid cleaner to enter the
mirror housing.
