Automatic dimming rear view mirror
The automatic dimming mirror is
equipped with an automatic
dimming feature. This feature will
change from the normal state to the
non-glare“active”state when bright
lights (glare) reach the mirror.
When the mirror detects bright light from behind, it will adjust
automatically to minimize glare.
The mirror will automatically return to the normal high reflective state
whenever the vehicle is placed in R (Reverse) (when the mirror is in the
ON position). This helps to ensure a bright clear view in the mirror when
backing up.
