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 Ignition ON/Vehicle in
Service Mode, 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 automatic ally darken
with the inside rearview mirror to reduce glare from
headlamps behind the vehicle.
Inside Rearview Camera Full Display
Mirror System Operation
The inside rearview camera full display mirror is
connected to the outside rearview camera via a
shielded coaxial cable. When the tab under the inside
rearview mirror is pulled rearward, a view of the area
behind the vehicle displays on the mirror. Adjust the
rearview mirror for a clear view of the area behind the
vehicle before turning on full display mirror. Use the
button on the back of the mirror to adjust the brightness
of the display. Make sure the light sensor is not covered
when adjusting the brightness.
The inside rearview camera full display mirror may not
work properly or display a clear image if:.
• It is dark.
• The sun or the beam of headlamps are shining
directly into the camera lens.
• Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
When the mirror detects that the camera is not sending
a valid video signal, it “blue screens” with a “no video”
decal for 3 seconds, then reverts back to the mirror.
Meanwhile, if a blue screen keeps on displaying
instead of the camera view, take the vehicle to your
dealer for service.
