To turn the mirror on, push the ON/OFF
switch, located on the bottom of the mirror, to
latch it in the ON position. The switch will
illuminate and the mirror will be in the
automatic dimming mode. To turn the switch
illumination and automatic dimming feature off,
push the ON/OFF switch again.
The electronic mirror measures the brightness of
the light coming in from the rear of the vehicle.
It automatically makes a correction in the glare
state. The mirror may be turned off in either the
normal or non-glare position.
There are two light sensors (photocells) in this
mirror. The sensor that detects rear glare is
located inside a window in the center of the
mirror. The second light sensor which
determines outside light level is located on the
backside of the mirror case.
One important safety feature is that the mirror
automatically returns to the normal position
whenever the vehicle is placed in R (Reverse)
(when the mirror is in the ON position). This
feature ensures a bright clear view in the mirror
when backing up.
