LS500_OM_OM50F54U_(U) The sensor may not function properly if an
object is placed on th e sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion. ■

automatically (after approximately 1 sec-
ond):
• 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 head-
lights or tail lights turned on.
• There are few streetlights on the road
ahead. ●
If any of the following conditions are met,
the high beams will turn off automatically:
• The vehicle speed is below approxi-
mately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or

Camera sensor dete ction information●
The high beams may not be automatically
turned off in the following situations:
• When a vehicle suddenly appears from
around a curve
• When the vehicle is cut in front of by
another vehicle
• When vehicles ahead cannot be
detected due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear in a far-
away lane on a wide road
• When the lights of vehicles ahead are not
on
●
The high beams may be turned off if a AHB (Automatic High
Beam) The Automatic High Beam uses a
camera sensor located behind the
upper portion of the windshield to
assess the brightness of the lights of
vehicles ahead, streetlights, etc.,
and automatically turns the high
beams on or off as necessary. WARNING■
Limitations of the Automatic High
Beam

Driving vehicle ahead that is using fog lights with-
out its headlights turned on is detected.●
House lights, street lig hts, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.●
The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles
ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient,
curve, condition of th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle●
The high beams may turn on or off unex-
pectedly.●
Bicycles or similar vehicles may not be
detected.●
In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. 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 switch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms, etc.)
