" 1 Near infrared floodlight (Night view projector)
2 Near infrared camera (Night view camera)
3 Head up display (Night view display)
4 Automatic light control sensor
The near infrared floodlight (night view projector which
irradiates near infrared light not seen by people) located
near the fog lights irradiates the area reaching from the tip
of the low beam to high beam. The near infrared camera
(night view camera) located on top of the windshield
converts irradiated light into an image. This image is
shown on the head up display (night view display)
located on the bottom of the windshield.
The automatic light control sensor is on top of the passenger
side instrument panel.
Do not place anything on the instrument panel and do not affix
anything on the windshield to block this sensor.
