Automatic Dimming Rearview Mirror
with OnStar
® and Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass and OnStar
®
controls. For more information about OnStar ® ,
see OnStar ® System on page 148.
The automatic dimming feature turns on each time
the vehicle is started. To turn automatic dimming
off or on, press the left button below the mirror.
A green indicator light will be on when automatic
dimming is on.
There are also three OnStar ® buttons located at
the bottom of the mirror. See your dealer for more
information on the system and how to subscribe
to OnStar
® . See OnStar ® System on page 148 for
more information about the service OnStar ®
provides.
Compass Operation
Press the on/off button once to turn the compass
on or off.
When the ignition and the compass feature are
on, the compass will show two character boxes for
a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show a
compass 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, note pad holder, or
similar object. If the letter C appears in the compass
window, the compass may need to be reset or
calibrated.
The mirror can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the
display reads a direction.
