4-3. Operating the lights and wipers
Driving
Pull the lever toward you and release it
again to turn off the lights.
When any of the following conditions is
met, while the headlights (low beam)
are on, the cornering lights will addi-
tionally turn on and light up the direc-
tion of movement for the vehicle. This is
to ensure excellent visibility when
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)
■Cornering light control
●The lights illuminate when the vehicle speed is approximately 30 km/h (19
mph) or less. However, the lights turn off when the vehicle speed increases to approximately 35 km/h (22 mph) or
more.
●After the lights remain illuminated for 30
minutes, they automatically turn off.
*:If equipped
1 Push the lever away from you with
the headlight switch in the or
position.
2 Press the Automatic High Beam
switch.
Cornering lights
Automatic High Beam*
The Automatic High Beam uses an
in-vehicle camera sensor to assess
the brightness of streetlights, the
lights of a vehicle ahead, etc., and
automatically turns the high beam
on or off as necessary.
WARNING
■Limitations 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.
■To prevent incorrect operation of the Automatic High Beam system
Do not overload the vehicle.

4-5. Using the driving support systems
*: If equipped
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the multi-
information display to urge the driver
to take evasive action.
■Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension sys-
tem ( P.262) will control the damping
force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.
■Steering control (if equipped)
When the system determines that the
possibility of a frontal collision is high
PCS (Pre-Collision System)*
The pre-collision system uses a
radar sensor and camera sensor to
detect vehicles and pedestrians*1 in
front of your vehicle. When the sys-
tem determines that the possibility
of a frontal collision with a vehicle
or pedestrian is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.212)
*1: Depending on the region in which
the vehicle was sold, the pedestrian
detection function may not be avail-
able. Contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer for details.

Driving
and the driver is operating the steering
wheel, the LDH system ( P.263) will
control the turning angle of the front
and rear wheels and effort necessary
to turn the steering wheel to help
enhance steering responsiveness.
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations under any circumstances. This system
will not prevent collisions or lessen col- lision damage or injury in every situa-tion. Do not overly rely on this system.
Failure to do so may lead to an acci- dent, resulting in death or serious injury.
●Although this system is designed to
help avoid a collision or help reduce the impact of the co llision, its effective- ness may change according to various
conditions, therefore the system may not always be able to achieve the same level of performance.
Read the following conditions care- fully. Do not overly rely on this system and always drive carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision: P.214
• Conditions under which the system
may not operate properly: P.215
●Do not attempt to test the operation of the pre-collision system yourself, as the system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of braking force will be applied.
●If the vehicle is stopped by the opera-tion of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after approximately 2seconds. Depress the
brake pedal as necessary.
●The pre-collision braking function may not operate if certain operations are performed by the driver. If the acceler-
ator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the
driver is taking evasive action and pos- sibly prevent the pre-collision braking function from operating.
●In some situations, while the pre-colli-
sion braking function is operating, operation of the function may be can-celed if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-mines that the driver is taking evasive
action.
●If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and pos- sibly delay the operation timing of the pre-collision braking function.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When transporting the vehicle via
truck, boat, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running operating> and the tires are allowed to rotate freely

4-5. Using the driving support systems
The system may not operate in the following situations:
●If a 12-volt battery terminal has been dis-connected and reconnected and then the vehicle has not been driven for a certain
amount of time
●If the shift position is in R
●If VSC is disabled (only the pre-collision warning function will be operational)
●If the PCS warning light is flashing or illu-minated
■Pedestrian detection function*2
The pre-collision system detects pedestri-
ans based on the size, profile, and motion of a detected object. However, a pedestrian may not be detected depending on the sur-
rounding brightness and the motion, pos- ture, and angle of the detected object, preventing the system from operating prop-
erly. ( P.215)
*2: Depending on the region in which the
vehicle was sold, the pedestrian detec-
tion function may not be available.
■Cancelation of the pre-collision braking
If either of the following occur while the pre-collision braking function is operating, it will be canceled:
●The accelerator pedal is depressed strongly.
●The steering wheel is turned sharply or abruptly.
■Conditions under which the system may
operate even if there is no possibility of a collision
●In some situations such as the following, the system may determine that there is a possibility of a frontal collision and oper-
ate.
• When passing a vehicle or pedestrian*2
• When changing lanes while overtaking a preceding vehicle• When overtaking a preceding vehicle
that is changing lanes • When overtaking a preceding vehicle that is making a left/right turn
• When passing a vehicle in an oncoming lane that is stopped to make a right/left
turn
• When driving on a road where relative
location to vehicle ahead in an adjacent lane may change, such as on a winding road
• When rapidly closing on a vehicle ahead • If the front of the vehicle is raised or low-
ered, such as when the road surface is uneven or undulating• When approaching objects on the road-
side, such as guardrails, utility poles, trees, or walls
• When there is a vehicle, pedestrian*2, or

■Lane departure alert function
When the system determines that the
vehicle might depart from its lane, a
warning is displayed on the multi-infor-
mation display, and either the warning
buzzer sounds to alert the driver.
When the warning buzzer sounds, check
the surrounding road situation and care-
fully operate the steering wheel to move
the vehicle back to the center of the lane.
■Steering assist function
When the system determines that the
vehicle might depart from its lane, the
system provides assistance as neces-
sary by operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
For Israel: If the system detects that the
steering wheel has not been operated for a
fixed amount of time or the steering wheel
is not being firmly gripped, a warning is dis-
played on the multi-information display
and the warning buzzer sounds.
Except for Israel: If the system detects that
the steering wheel has not been operated
for a fixed amount of time or the steering
wheel is not being firmly gripped, a warn-

LKA (Lane-Keeping Assist)*
When driving on highways and
freeways with white or yellow lines,
this function alerts the driver when
the vehicle might depart from its
lane and provides assistance by
operating the steering wheel to
keep the vehicle in its lane. Further-
more, the system also provides
steering assistance when dynamic
radar cruise control with full-speed
range is operating to keep the vehi-
cle in its lane.

WARNING
■Before using LKA system
Do not rely solely upon the LKA system. The LKA system does not automatically
drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must
always assume full responsibility for driv- ing safely by paying careful attention to the surrounding conditions and operat-
ing the steering wheel to correct the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time. Failure to perform appropriate driving operations and pay careful attention may
lead to an accident, resulting in death or serious injury.
■To avoid operating LKA system by mistake
When not using the LKA system, use the LKA switch to turn the system off.
