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.
Glare-free high beam
This feature dims only the high-beam light shone on the vehicle ahead.
The high beams will dim while driving at a speed of about 30 km/h (19 mph) or
faster. When the vehicle speed is less than about 20 km/h (12 mph), the beams
switch to the low beams.
NOTE
The headlight high-beam indicator light turns on while the high beams are on.
Wide-range low beam
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.
