either driving at intersections or park-
ing at night.
The steering wheel is operated 
The turn signal lever is operated
 The shift position is in R (both left
and right side cornering lights)
QCornering light control
OThe lights illuminate when the vehicle
speed is approximately 19 mph (30
km/h) or less. However, the lights turn off
when the vehicle speed increases to
approximately 22 mph (35 km/h) or
more.
OAfter the lights remain illuminated for 30
minutes, they automatically turn off.

met, the high beam will be automatically
turned on (after approximately 1 second):
• Vehicle speed is above 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.
OIf any of the following conditions are met,
the high beam will be automatically
turned off:
• Vehicle speed drops below approxi- mately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.

ers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
OThe high beam may be turned off if a
vehicle ahead that is using fog lights with-
out using the headlights is detected.
AHB (Automatic High
Beam)
The Automatic High Beam uses an
in-vehicle front camera to assess
the brightness of streetlights, the
lights of vehicle ahead, etc., and
automatically turns the high beam
on or off as necessary.
WARNING
QLimitations of the Automatic High
Beam
Do not rely on the Automatic High
Beam. Always drive safely, taking care to
observe your surroundings and turning
the high beam on or off manually if nec-
essary.
QTo prevent incorrect operation of the
Automatic High Beam system
Do not overload the vehicle.

Driving
OHouse lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beam to switch to the low
beams, or the low beams to remain on.
OThe following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of 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 the road surface etc.)
• The number of passengers and amount of luggage
OThe high beam may be turned on or off
when the driver does not expect it.
OBicycles or similar objects may not be
detected.
OIn the situations shown below, the system
may not be able to accurately detect sur-
rounding brightness levels. This may
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• 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 front camera is deformed or dirty
• When the temperature of the front cam- era is extremely high
• Surrounding brightness levels are equal to those of headlights, 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
• There is a highly reflective object ahead
of the vehicle, such as a sign or a mirror
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty
• The vehicle is listing or tilting, due to a flat
tire, a trailer being towed etc.
• The high beam and low beam are repeat- edly being switched between in an
abnormal manner
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby
QTemporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the power switch off while the fol-
lowing conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in low beam position.
• Automatic High Beam switch is on.
2 Turn the power switch to ON mode.
3 Within 60 seconds after 2, repeat pull-
ing 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.

WARNING
QLexus Safety System + 2.5
The Lexus Safety System + 2.5 is
designed to operate under the assump-
tion that the driver will drive safely, and is
designed to help reduce the impact to
the occupants and the vehicle in the case
of a collision or assist the driver in normal
driving conditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surroundings and driving
safely.
