Operating instructions

1874-3. Operating the lights and wipers
LS500h_OM_OM50F42U_(U) 4
Driving Pull the lever toward you to the center
position to turn the high beams off.
2 Pull the lever toward you and
release it to flash the high beams
once.You can flash the high beams with the
headlights on or off.
AFS (Adaptive Front-lighting System)
secures excellent visibility at intersec-
tions and on curves by automatically
adjusting the direction of the light axis
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.
■
Customization
Some functions can be customized.
( → P.481)
 When the steering wheel or turn
signal lever is operated while the
headlights are on (low beam), a cor-
nering light will turn on and light up
the direction of movement of the
vehicle. The cornering lights are
designed to ensure excellent visibil-
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 the headlights are on (low beam),
both cornering lights will turn on.
This is designed to enhance visibility
when parking. ■
Cornering lights
When the cornering lights are on for more
than 30 minutes, they will turn off automati-
cally.

1894-3. Operating the lights and wipers
LS500h_OM_OM50F42U_(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 ■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the power switch on while the fol-
lowing conditions are met.
●
The headlight switch is in or . ●
The headlight switch lever is in high beam
position. ●
Automatic High Beam switch is on.
2 Turn the power switch to ON mode.
3 Within 30 seconds after step 2 , repeat
pulling the headlight switch lever to the
original position then pushing it to the
high beam position quickly 10 times,
then leave the lever in high beam posi-
tion.
4 If the sensitivity is changed, the AHB
indicator is turn on and off 3 times.
Automatic High Beam (headlights) may
turn on even when the vehicle is stopped.

2314-5. Using the driving support systems
LS500h_OM_OM50F42U_(U) 4
Driving overtaking vehicle in the adjacent lane
is high, the lane departure alert will
operate even if the turn signals are
operating.
■
Steering assist function
When the system determines that the
vehicle might depart from its lane or
course *
, the system provides assis-
tance as necessary by operating the
steering wheel in small amounts for a
short period of time to keep the vehicle
in its lane. *
: Boundary between asphalt and the side
of the road, such as grass, soil, or a curb
If the system detects that the steering
wheel has not been operated for a cer-
tain amount of time or the steering
wheel is not being firmly gripped, the
steering assist function may be can-
celed temporarily, a warning message
may be displayed on the multi-informa-
tion display and a warning buzzer may sound. If the steering assist function is
canceled, release the steering wheel
and then grip it again to enable the
function.
When the system determines that the
vehicle might depart from its lane and
that the possibility of a collision with an
overtaking vehicle in the adjacent lane
is high, the steering assist function will
operate even if the turn signals are
operating.
■
Vehicle sway warning function
When the vehicle is swaying within a
lane, the warning buzzer will sound and
a message will be displayed on the
multi-information display to alert the
driver.

236 4-5. Using the driving support systems
LS500h_OM_OM50F42U_(U) The curve display on the head-up display
changes according to the direction and
curvature of the curve. ■
