Automatic Dimming Rearview Mirror
with Onstar@
Your vehicle may be equipped with an automatic
dimming rearview mirror with the Onstar@ System.
The automatic dimming feature is turned on or
off
by
pressing the far left button, located on the lower part of
the mirror, for up to three seconds. While turned on,
this mirror functions exactly like the automatic dimming
mirror described previously.
There are two lamps located on the bottom of the
mirror. Each lamp is turned on and
off
by pressing the
button next to the lamp.
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 OnStap System on page 2-37 for more
information about the service Onstar@ provides.
