Electrochromic Day/Night Rearview Mirror
(If Equipped)

Your vehicle may have an automatic electrochromic
day/night rearview mirror. Your vehicle’s mirror may
also contain OnStar

R

 controls.

This is the on/off button for mirrors equipped with

OnStar controls.

When this 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 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

To turn on the automatic dimming feature, press AUTO
(or the on/off button for mirrors equipped with OnStar
controls). To turn off automatic dimming, press OFF 
(or the on/off button for mirrors equipped with OnStar
controls). The indicator light will be illuminated when
this feature is active.

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 (or the on/off button 
for mirrors equipped with OnStar controls) located at
the bottom of the mirror, 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.
