Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž
Your vehicle may have an automatic dimming rearview
mirror with OnStaržsystem controls. For more
information about OnStarž, seeOnStaržSystem on
page 2-45.
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):This is the on/off button, located on the
lower left side of the mirror face.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will be illuminated
when the automatic dimming feature is on.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Automatic Dimming Rearview Mirror
with OnStar
žand Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
žcontrols. For more information seeOnStaržSystem on page 2-45.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. See
Automatic Dimming Rearview Mirror
with OnStaržon page 2-40.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.

Your vehicle may be
equipped with the memory
package. The controls
for these features
are located on the driver's
door panel, and are
used to program and recall
memory settings for the
driver's seating positions.
Use the following steps to program each button:
1. Adjust the driver's seat including the seatback
recliner, lumbar and head restraint, both outside
mirrors and the steering wheel to a comfortable
position.
2. Press the SET button.
3. Within ®ve seconds, press button 1. After a brief
delay, a single beep will sound through the driver's
side front speaker to let you know that the
position has been stored.A second mirror, seating and steering wheel position
can be programmed by repeating the above steps and
pressing button 2 (for driver 2). Each time a memory
button is pressed, a single beep will sound. Each time
button 1 or 2 is pressed and released while the
vehicle is in PARK (P), the memory positions will be
recalled after a brief delay. If the vehicle is not in PARK
(P), the memory buttons must be pressed and held
to recall the stored positions.
If you use the remote keyless entry transmitter to enter
your vehicle, automatic seat and mirror movement
will occur. The numbers on the back of the transmitters,
1 and 2, correspond to the numbers on the buttons
on the door panel.
When the key is placed in the ignition in OFF and you
have entered the vehicle without using the remote
keyless entry transmitter, the seat and mirrors
will automatically adjust to the programmed position of
the last driver.
To stop recall movement of the memory feature at any
time, press one of the power seat controls or memory
buttons.
