Automatic Dimming
Your vehicle is equipped with an 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 approximately three seconds to turn
the compass on or off.
When the ignition and the compass feature are
on, the compass will show two character boxes
for about two seconds. After two seconds,
the mirror will display the compass heading.
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 approximately nine seconds
untilaCisshown 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 a direction.
