When Driving
Adaptive LED Headlights (ALH)
The ALH are a system which uses the Forward Sensing Camera (FSC) to determine
the situation of a vehicle ahead or a vehicle approaching in the opposite direction
while driving at night to automatically switch the illumination range of the
headlights, the illuminated area, or the illumination brightness.
This feature dims only the high-beam light shone on the vehicle ahead.
Glare-free high beam
Wide-range low beam
The high beams will dim while driving at a speed of about 40 km/h (25 mph) or
faster. When the vehicle speed is less than about 30 km/h (19 mph), the beams
switch to the low beams.
This feature extends the illumination range of the light cast by the low beams
while driving at a speed less than about 40 km/h (25 mph).
Highway mode
This feature shifts the illumination angle of the light cast by the headlights
upward while driving on highways.
The ALH operates to control Glare-Free High Beam, Wide-Range Low Beam and
Highway Mode automatically after the ignition is switched ON and the headlight switch
is in the and low beam position.
The ALH determines that it is dark based on the brightness of the surrounding area. At
the same time, the ALH indicator light (green) in the instrument cluster illuminates.
