Automatic-Dimming Night Vision Safety

The NVS Mirror in your vehicle is the most advanced way to eliminate dangerous and
annoying glare in the rearview mirror during any driving situation. For more information
regarding NVS mirrors and other applications, please refer to the Gentex website –

Precautions

The NVS Mirror automatically reduces glare during driving conditions based upon light levels
monitored in front of the vehicle and from the rear of the vehicle. These light sensors are visible
through openings in the front and rear of the mirror case. Any object that would obstruct either
light sensor will degrade the automatic dimming control feature.

The NVS Mirror operates automatically whenever the vehicle ignition is ON. The status of the
automatic dimming feature is indicated by a green light on the face of the mirror.
