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 ® , see OnStar ® 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. See Automatic 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.
