The mirror includes an eight-point compass display in
the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle is
driven. Outside temperature is also shown in the display.
Automatic Dimming
Your vehicle has an inside automatic dimming rearview
mirror. The automatic dimming feature is activated
whenever the vehicle is turned on and dims only during
nighttime driving.
Compass Operation
AUTO 3: Press and hold the “auto highbeam” button
for about three seconds to turn the
compass/temperature display on or off.
When the ignition and the display features are on, the
display will show two character boxes for about two
seconds. After two seconds, the mirror will display the
compass heading and temperature.
Compass Calibration
If after two seconds the display does not show the
correct direction, (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 can be placed in calibration mode
manually by pressing and holding the “auto highbeam”
button for about nine seconds until CAL is shown in
the compass display.
The mirror can then be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads the correct direction.
