Electrochromic Automatic Dimming
Rearview Mirror (If Equipped)
Your vehicle may have an electrochromic dayhight
rearview mirror. Push the button in the center of the
mirror to turn this feature on. The mirror will darken
gradually to reduce glare from headlamps behind you.
This may take a few moments.
The mirror's two outer buttons operate the lights on the
bottom sides of the mirror.
One photocell on the front of the mirror senses when it
is becoming dark outside. Another photocell, facing
rearward, senses headlamps behind you. To turn the
electrochromic feature off, press the button in the center
of the mirror again.
To keep the photocells operating well, occasionally
clean them with a cotton swab and glass cleaner.
Power Outside Foldaway Mirrors
. ,... ..
ii
The power mirror control
switches are located near
the driver's side window, on
the armrest. To choose
either the left or right
outside mirror, move the top
switch from left through
neutral to right. Press any of
the four buttons located
below the top switch to
move the mirrors in the
desired direction.
Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle.
These mirrors can also be folded rearward manually.
This feature is particularly useful in automatic car
washes and when maneuvering your vehicle in
narrow spaces.
