headlamps behind you. Push the tab away from
you for daytime use; pull it toward you for night use.
Automatic Dimming Rearview Mirror
Your vehicle may have an automatic dimming rearview
mirror. Your vehicle’s mirror may also contain Onstar@
controls. See
OnStaP System on page 2-40 for

Press the left or right side of the UR selector switch
located beneath the control pad to choose the left
or right mirror.
To adjust the mirror, use one of the four arrows located
on the control pad to move the mirror in the direction
you want it to go. When finished adjusting the mirrors,
leave the UR selector switch in the center position,
to prevent unwanted mirror movement in case the
control pad is accidentally bumped while driving. Adjust
each outside mirror
so that you can see a little of
your vehicle and the area behind your vehicle.
If your vehicle is equipped with the memory function,
the mirrors and driver’s seat position can be stored into
memory. See
Memory Seat and Mirrors on page 2-48.
Qutside Curb View Assist Mirror
If you have the memory seat and mirrors feature, the
passenger’s outside power mirror also includes a
tilt-down feature that operates when the shift lever is in
REVERSE (R). When the vehicle is shifted out of
REVERSE
(R), the passenger’s mirror wtii return to ils
original position after a five-second delay. This delay
prevents movement of the mirror
if multiple gear
transitions (REVERSE
(R) to DRIVE (D) to
REVERSE (R)) occur during a parallel parking
maneuver. This feature can be programmed on or
off
through the DIC personalization programming menu.
See
DIC Vehicle Personalization on page 3-62 for
programming instructions.
Outside Convex Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from the
ver’s seat.
A convex mirror can make things (like other
vehicles)
look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
If vour vehicle has this feature, when you operate the
rear window defogger, the heated driver’s and
passenger’s outside power mirrors are warmed to help
clear them of ice and snow. See “Rear Window
Defogger’’ under
Climate Control System on page 3-25
or Automatic Climate Control System on page 3-28
for more information.
