Automatic Dimming Rearview Mirror
with
Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. Your vehicle’s mirror may also
contain OnStaP controls. See
OnStaP
system
on
page
2-40
for more information.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face.
When 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.
Mirror Operation
MIRROR:
Press this button to turn on the automatic
dimming feature. Press it again to turn off the automatic
dimming feature.
(On/Off):
For mirrors equipped with OnStaP
controls, press and hold this button for several seconds
to turn on the automatic dimming feature. Press and
hold
it
again to turn the automatic dimming feature off.
The green indicator light will come on when this
feature
is
active. The automatic dimming feature will be
active each time the vehicle is started.
Compass Operation
COMPASS:
Press this button once to turn the compass
on
or
off.
(On/Off):
For mirrors equipped with OnStap
controls, press this 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
approximately two seconds. After two seconds,
the mirror will display the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven.
If,
after two 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.
If
the letter
C
should ever appear in
the compass window, the compass may need calibration.
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.
Mirrors equipped with OnStar@ controls can be placed
in calibration mode by pressing and holding the
on/off button until a
C
is shown in the compass display.
