Acura’s Automatic High-Beam system uses a small camera in the windshield to detect lights ahead of the vehicles. This system can have a powerful impact on nighttime driving by providing enhanced illumination when necessary. This video demonstrates how to activate this feature, but keep in mind that the Automatic High-Beam system will not work in certain conditions that affect the sensor.
When you are driving at night above 35 mph (56 km/h) and the headlight lever is in the low beam position with the switch rotated to AUTO, the system changes between low and high beams depending on the surrounding conditions.  If a vehicle is detected ahead of you, the headlights stay in low beams. If the
system does not detect any vehicles ahead of you, the headlights change to high beams.
Certain conditions, such as weather and brightness of other vehicles’ lights, can
affect system operation.
