4-3. Operating the lights and wipers
■Door opening linked windshield wiper stop function
When AUTO is selected and the wind- shield wipers are operating, if a door is opened, the operation of the windshield
wipers will be stopped to prevent anyone near the vehicle from being sprayed by water from the wipers, provided the vehicle
is stopped. When the door is closed, wiper operation will resume.
■To protect the windshield wipers
If movement of the windshield wipers is largely restricted by a foreign object such as snow, the operation of the windshield wip-
ers may be stopped automatically to pro- tect the windshield wipers. In this case, turn the windshield wiper switch off and remove
the foreign object, and then use the wind- shield wipers.
■When stopping the engine <hybrid sys-
tem> in an emergency while driving
If the windshield wipe rs are operating when
the engine <hybrid system> is stopped, the windshield wipers will operate in high speed operation. After the vehicle is stopped,
operation will return to normal when the engine switch <power switch> is turned to IGNITION ON mode <ON mode>, or
operation will stop when the driver’s door is opened.
■Customization
The rain-sensing operation setting can be changed. (Customizable features: P.423)
When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-
tions or when replacing a windshield
wiper insert, change th e rest position of
the windshield wipers to the service
WARNING
■Caution regarding the use of wind- shield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the windshield is subject to vibration in
AU TO mod e . T ak e c are t ha t you r fin ge rs or anything else do not become caught in the windshield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm. The fluid may freeze on the windshield and cause low visibility. This may lead to
an accident, resulting in death or serious injury.
NOTICE
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward
you and held continually.
■When a nozzle becomes blocked
In this case, contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer. Do not try to clear it with a pin or other
object. The nozzle will be damaged.

4-5. Using the driving support systems
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 <hybrid system
operating> and the tires are allowed to rotate freely

object by the roadside at the entrance of a curve
• When driving on a narrow path sur- rounded by a structure, such as in a tun-nel or on an iron bridge
• When there is a metal object (manhole cover, steel plate, etc.), steps, or a protru-sion on the road surface or roadside
• When a crossing pedestrian approaches
very close to the vehicle*2
• When passing through a place with a low structure above the road (low ceiling,
traffic sign, etc.)
• When passing under an object (billboard,
etc.) at the top of an uphill road
• When rapidly closing on an electric toll gate barrier, parking area barrier, or other barrier that opens and closes
• When using an automatic car wash • When driving through or under objects that may contact the vehicle, such as thick
grass, tree branches, or a banner
• When the vehicle is hit by water, snow,
dust, etc. from a vehicle ahead • When driving through steam or smoke• When there are patterns or paint on the
road or a wall that may be mistaken for a
vehicle or pedestrian*2
• When driving near an object that reflects radio waves, such as a large truck or guardrail
• When driving near a TV tower, broad- casting station, electric power plant, or other location where strong radio waves
or electrical noise may be present*2: Depending on the region in which the
vehicle was sold, the pedestrian detec-
tion function may not be available.
■Situations in which the system may not operate properly
●In some situations such as the following, a vehicle may not be detected by the radar
sensor and camera sensor, preventing the system from operating properly:• If an oncoming vehicle is approaching
your vehicle • If a vehicle ahead is a motorcycle or bicy-

WARNING
●Assisting the driver to measure follow- ing distance
The dynamic radar cruise control with
full-speed range is on ly intended to help
the driver in determ ining the following
distance between the driver’s own vehi-
cle and a designated vehicle traveling
ahead. It is not a mechanism that allows
careless or inattentive driving, and it is
not a system that can assist the driver in
low-visibility conditions. It is still neces-
sary for driver to pay close attention to
the vehicle’s surroundings.
●Assisting the driver to judge proper following distance
The dynamic radar cruise control with
full-speed range determines whether the
following distance between the driver’s
own vehicle and a designated vehicle
traveling ahead is within a set range. It is
not capable of making any other type of
judgement. Therefore, it is absolutely
necessary for the driver to remain vigi-
lant and to determine whether or not
there is a possibility of danger in any
given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range has limited capability to
prevent or avoid a collision with a vehicle
traveling ahead. Therefore, if there is
ever any danger, the driver must take
immediate and direct control of the vehi-
cle and act appropriately in order to
ensure the safety of all involved.
■To avoid inadvertent dynamic radar cruise control with full-speed range
activation
Switch the dynamic radar cruise control
with full-speed range off using the cruise control main switch when not in use.
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control
with full-speed range in any of the follow- ing situations.
Doing so may result in inappropriate speed control and could cause an acci-dent resulting in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those cov- ered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sen-sors from detecting correctly (fog,
snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or camera sensor
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●During emergency towing

• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch <power switch>
is turned off once and turned to IGNI- TION ON mode <ON mode> again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding environment may affect the ability of the sensor to correctly detect
obstacles. Particular instances where this may occur are listed below.• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, or on grass. • The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor in the vicinity.• The sensor is splashed with water or
heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rap-idly from behind into a blind spot. Do not
overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to
an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
