CAUTION:

It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake firmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake after you move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. See Shifting Into Park (P) on page 2-36.

Automatic Dimming Rearview Mirror
®
with OnStar
Your vehicle may have an automatic dimming rearview
®
mirror with OnStar system controls. For more
information about OnStar
page 2-46.
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.
