Electrochromic Day/Night Rearview Mirror
with Compass, Temperature Display, and
OnStar
(Option)
Your vehicle may have an automatic-dimming rearview
mirror with a compass and temperature display and the
OnStar system.
When turned on, this mirror functions exactly
like the electrochromic mirror described previously.
See “Mirrors, Electrochromic Rearview” in the
Index for more information.
The mirror also has an eight
-point compass and
temperature display in the upper right corner on the
mirror face and a three-button OnStar system.
Automatic Dimming Feature
The automatic dimming feature is turned on and off by
pressing the far left button, located on the lower part of
the mirror face, for up to three seconds. A light on the
mirror will be lit when the feature is turned on. It will go
out when the feature is turned off.
Temperature Display
The on/off button located on far left on the bottom
of the mirror face changes the temperature display.
You can select F, C, or turn the display off.
Compass Operation
There is a compass display in the window in the upper
right corner of the mirror face. The compass displays a
maximum of two characters. For example, “NE” is
displayed for north
-east.
The compass may need to be calibrated. See “Compass
Calibration” in the Index for more information.
There are three buttons for the OnStar system. See your
dealer for more information on the system and how to
subscribe to OnStar. See “OnStar System” in the
Index for more information about the services
OnStar provides.
