Interior Mirrors
Automatic Dimming
Rearview Mirror
An automatic dimming inside
rearview mirror will automatically
change to reduce glare from
headlamps behind you. A time
delay feature prevents rapid
changing from the day to night
positions while driving under lights
and through traffic.
If the vehicle has OnStar
®
, there are
additional control buttons located at
the bottom of the mirror. See OnStar
Overview on page 14‑1.
P (On/Off): The automatic
dimming feature is activated when
the vehicle is started. Press and
hold this button for up to
six seconds to turn this feature
on or off.
T (Indicator Light): This light turns
on when the automatic dimming
feature is active.
Map Lamps
If the mirror has map lamps, they
are located at the bottom of the
mirror. To manually turn the lamps
on or off, press the button next to
each lamp.
Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.
