Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)

Your vehicle may have an electrochromic inside
rearview mirror with a compass. Your vehicle’s mirror
may also contain OnStar

R

 controls.

  This is the on/off button for mirrors equipped with

OnStar controls.

Pressing the MIRROR button located at the bottom of
the mirror (or the on/off button for mirrors equipped
with OnStar controls), turns the automatic dimming
feature on or off.

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.

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

To turn on the automatic dimming feature, press 
the MIRROR button located at the bottom of the 
mirror (or press and hold the on/off button for about

three seconds for mirrors equipped with OnStar controls).
To turn off automatic dimming, press MIRROR (or press
and hold the on/off button for about three seconds for
mirrors equipped with OnStar controls) again. The green
indicator light will be illuminated when this feature is
active. The automatic dimming feature will be active each
time the vehicle is started.

Compass Operation

Press COMPASS (or the on/off button for mirrors
equipped with OnStar controls) 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
approximately two seconds. After two seconds, the
mirror will display the compass heading.

Compass Calibration

If, after two seconds, the display does not show a
compass heading (N for North, for example), there may
be a strong magnetic field interfering 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.
