Automatic operating conditions of the
high beams
When all of the following conditions are
●
met, the high beams will illuminate auto-
matically:
• The vehicle speed is approximately 21
mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with lights
on.
• There are few streetlights or other lights
on the road ahead.
●
If any of the following conditions are met,
the headlights will change to the low
beams:
• Vehicle speed drops below approxi-
mately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• There is a vehicle ahead with lights on.
• There are many streetlights or other
lights on the road ahead.
Front camera detection
■
In the following situations, the high beams
●
may not be automatically changed to the
low beams:
• When a vehicle cuts in front of your vehi-
cle
• When another vehicle crosses in front of
the vehicle
• When vehicles ahead are repeatedly
detected and then hidden due to
repeated curves, road dividers or road-
side trees
• When a vehicle ahead approaches from
a far lane
• When a vehicle ahead is far away
• When a vehicle ahead has no lights
• When the lights of a vehicle ahead are
dim
• When a vehicle ahead is reflecting strong
light, such as own headlights
• Situations in which the sensors may not
operate properly: P.273
●
The headlights may change to the low
beams if a vehicle ahead that is using fog
lights without its headlights turned on is
detected.
●
House lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beams to change to the
low beams, or the low beams to remain
on.
The following may change the timing at
●
which the headlights change to the low
beams:
• The brightness of lights of vehicles ahead
• The movement and direction of vehicles
ahead
• The distance between the vehicle and a
vehicle ahead
• When a vehicle ahead only has lights illu-
minated on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient,
curve, condition of the road surface, etc.)
• The number of passengers and amount of
luggage
●
The headlights may change between the
high beams and low beams unexpectedly.
Bicycles and other small vehicles may not
●
be detected.
●
In the following situations, the system may
not be able to correctly detect the bright-
ness of the surroundings. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually change between the
high beams and low beams.
• When there are lights similar to head-
lights or tail lights in the surrounding area
