Camera sensor detection information
■
●
High beam may not be automatically
turned off in the following situations:
• When oncoming vehicles suddenly
appear from a curve
• When the vehicle is cut in front of by
LEXUS NX300/NX200 Owners Manual̲General̲M78540̲en
another
• When oncoming or preceding vehicles
are hidden from sight due to repeated
curves, road dividers or roadside trees
●
High beam may be turned off if an
oncoming vehicle that is using fog lights
without using the headlights is detected.
House lights, street lights, red traffic sig-
●
nals, and illuminated billboards or signs
may cause the high beam to turn off.
●
The following factors may affect the
amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights,
and tail lights of oncoming and preceding
vehicles
• The movement and direction of oncom-
ing and preceding vehicles
• When a oncoming or preceding vehicle
only has operational lights on one side
• When a oncoming or preceding vehicle
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
●
High beam may be turned on or off when
unexpected by the driver.
In the situations below, you should con-
●
sider turning the high beams on or off
manually rather than relying on the Auto-
matic High Beam system.
• The system is not able to correctly detect
the surrounding brightness levels, and
flashes or exposes nearby pedestrians to
the high beam.
• In bad weather (rain, snow, fog, sand-
storms, etc.)
• The windshield is obscured by fog, mist,
ice, dirt, etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is
extremely high.
• Surrounding brightness levels are equal
to those of headlights, tail lights or fog
lights.
• Vehicles ahead have headlights or tail
lights that are either switched off, dirty,
are changing color, or are not aimed
properly.
