When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. The day-night adjustment allows you to
adjust the mirror to avoid glare from the headlamps
behind you.
The integral reading lamps are turned on or off by
pressing the toggle switch at the bottom of the mirror.
These lamps are also part of the courtesy lamps
described earlier in this section.
Electrochromic Day/Night Rearview Mirror
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror.
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. To turn off automatic dimming, press OFF.
The green indicator light will be illuminated when this
feature is active.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
