Automatic Day-Night Mirror
Description and Operation
Inside Rearview Mirror with the
Automatic Day-Night Feature System
Operation
The inside rearview mirror uses 2 photocell sensors.
One sensor is the headlight sensor, located on the face
side of the mirror. The headlight sensor is used to
determine light conditions present at the mirror face.
The other sensor is the ambient light sensor, located on
the rear of the mirror or windshield side. The ambient
light sensor is used to determine the exterior light
conditions. With a low exterior light condition detected,
and a high light condition from behind the car, at the
headlight sensor, the inside rearview mirror will
automatically darken the face of the mirror.
In the daytime, the mirror is in a normal state because
of the high exterior light condition that is indicated by
the ambient light sensor. With the gear selector lever in
the REVERSE position and the engine running, backup
lamp supply voltage is supplied as an input to the inside
rearview mirror. The mirror monitors this input to
disable the automatic day-night feature. This allows the
driver to see objects in the mirror clearly when backing
up, even during the night.
Driver Outside Rearview Mirror with
Automatic Day-Night System Operation
(If Equipped)
The automatic day-night feature of the driver outside
rearview mirror is controlled by the inside rearview
mirror. The inside rearview mirror supplies control and
low reference to the driver outside rearview mirror. At
night, with the automatic day-night feature enabled, the
driver outside rearview mirror will automatically darken
with the inside rearview mirror to reduce glare from
headlamps behind the vehicle.
