Precautions
The Automatic-Dimming 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.
Automatic-Dimming Function
To protect your vision during nighttime driving, your mirror will automatically dim upon
detecting glare from the vehicles traveling behind you. The auto-dimming function is
active when the Ignition is “ON” and cannot be disabled.
