AHB is a safety system designed to help drivers see more of what’s ahead at
nighttime and reduce glare for oncoming drivers. When enabled, AHB uses an
in-vehicle camera to help detect the headlights of oncoming vehicles and tail lights
of preceding vehicles, then automatically switches between high and low beams
as appropriate to provide the most light possible and enhance forward visibility.
By using high beams more frequently, the system may allow earlier detection of
pedestrians and obstacles.
Refer to the Toyota Owner’s Manual for additional information on AHB operation,
settings adjustments, limitations, and precautions before attempting to use it.
