of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input. AFS operates at speed s of approximately
6 mph (10 km/h) or higher.

ity when making a turn at an inter-
section. However, when vehicle speed is approxi-
mately 22 mph (35 km/h) or higher, the
cornering lights will not turn on.  When the shift position is in R while

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

Beam

1794-3. Operating the lights and wipers
LS500_OM_OM50F54U_(U) 4
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.)
• When the windshield is obscured by fog,
mist, ice, dirt, etc.
• When the windshield is cracked or dam-
aged
• When the camera sensor is deformed or
dirty
• When the temperature of the camera
sensor is extremely high
• When the surrounding brightness level is
equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles
ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle • When driving through an area of inter-
mittently changing brightness and dark-
ness
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking
curves or driving on a winding road
• When there is a highly reflective object
ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is
highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to
a flat tire, a trailer being towed, etc.
• When the headlights are changed
between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high
beams may be flashing or dazzling
pedestrians or other drivers ■
