Mirrors
Manual Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up
or down and side to side. The day/night adjustment
allows you to adjust the mirror to avoid glare from any
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. SeeOnStar®System on page 2-37for
more information.
At night, when the glare is too high, 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
AUTO:Press this button to turn on the automatic
dimming feature.
OFF:Press this button to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press this button to turn on the automatic
dimming feature. To turn off automatic dimming, press
this button again.
The indicator light will be illuminated when this feature
is active.
Automatic Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. Your vehicle’s mirror may
also contain OnStar
®controls. SeeOnStar®System on
page 2-37for more information.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face.
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.

Mirror Operation
MIRROR:Press this button to turn on the automatic
dimming feature. Press it again to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press and hold this button for several seconds
to turn on the automatic dimming feature. Press and
hold it again to turn the automatic dimming feature off.
The green indicator light will come on when this
feature is active. The automatic dimming feature will be
active each time the vehicle is started.
Compass Operation
COMPASS:Press this button once to turn the compass
on or off.
O(On/Off):For mirrors equipped with OnStar®controls,
press this button once to turn the compass on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass heading (N for North, for
example), there may be a strong magnetic eldinterfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item. If the letter
C should ever appear in the compass window, the
compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
Mirrors equipped with OnStar
®controls can be placed
in calibration mode by pressing and holding the
on/off button untilaCisshown in the compass display.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set in zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate for
compass variance if you live outside zone eight. Under
certain circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the following zone map.

2. Press and hold COMPASS (or the on/off button for
mirrors equipped with OnStar®controls) until a
zone number appears in the display.
3. Once a zone number appears in the display, press
the COMPASS button (or the on/off button for
mirrors equipped with OnStar
®controls) quickly until
the correct zone number appears in the display.
Stop pressing the button and the mirror will return to
normal operation. If C appears in the compass
window, the compass may need calibration. See
“Compass Calibration” explained previously.
Outside Power Mirrors
The controls for the
outside power mirrors are
located on the driver’s
door armrest.
Press the left or right side of the L/R selector switch
located beneath the control pad to choose the left
or right mirror.
To adjust the mirror, press one of the four arrows
located on the control pad to move the mirror in the
direction you want it to go. When nished adjusting the
mirrors, leave the L/R 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.
