Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®
Your vehicle may have an automatic dimming rearview
mirror with OnStar®system controls. For more
information about OnStar®, seeOnStar®System on
page 2-42.
When the automatic dimming feature is turned on, the
mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the mirror senses
when it is becoming dark outside. Another photocell
built into the mirror face senses when headlamps
are behind you.
At night, when the glare is too bright, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear,
daytime state when the glare is reduced.
Mirror Operation
O
(On/Off):Press the on/off button, located on the
lower left side of the mirror face, to turn the automatic
dimming feature on or off. The indicator light will be
illuminated when the automatic dimming feature is on.
Cleaning the Mirror
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.

Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
®controls. For more information see
OnStar®System on page 2-42.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. SeeAutomatic Dimming Rearview Mirror
with OnStar
®on page 2-37.
The mirror also 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.
Mirror Operation
O
(On/Off):Press and hold the button, located on the
lower left side of the mirror face, for about three seconds
to turn the automatic dimming feature on or off.
The indicator light will illuminate when this feature is
active. The automatic dimming feature is active each time
the vehicle is started.
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 about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
If after two seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic eld 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.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button
untilaCisshown in the compass display.
