Buzzer operation and di stance to an obstacle
A beep sounds when the corner sensors and center sensors are operat-
ing.
● The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle,
the buzzer sounds continuously.
• Front corner sensors: Approximately 1.1 ft. (35 cm)
• Front center sensors: Approximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.3 ft. (40 cm)
● When 2 or more obstacles are detected simultaneously, the buzzer
system responds to the nearest obstacle.

Sensors that operate
■ Detection range of the sensors
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
Approximately 1.8 ft. (55 cm)
The diagram shows the detection
range of the sensors. Note that the

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
•A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, 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 sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shape, signs and other objects may be judged by a sensor to be closer than they
are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
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 projecting outwards in the direction of your vehicle

■When there is a malfunction
In the following cases, have the vehicle inspected by your Lexus dealer
●If the bumper is damaged.
●If the distance display remains on without a buzzer sound.
■If a message is displayed
→P. 7 0 0
■Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■Customization that can be configured at Lexus dealer
Settings (e.g. buzzer volume) can be changed. (Customizable features →P. 7 8 2 )
CAUTION
■Caution when using the Intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
●Do not use the sensor at speeds in excess of 8 mph (13 km/h).
●Do not attach any accessories within the sensor range.
NOTICE
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

LDA (Lane Departure Alert)∗
∗: If equipped
While driving on a freeway or motor highway that has lane markers, this
system recognizes the lanes using a camera as a sensor to alert the driver
when the vehicle deviates from its lane.
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping and indications on the multi-information
display.
■Turning the LDA system on
The system will be activated depending on the recognizability of
lane markers and on the vehicle speed.
Press the “LDA” switch to acti-
vate the system.
The “LDA” indicator will come
on.
Press the switch again to turn
the LDA system off.

■When the vehicle has been parked in the sun
The LDA system may not be available for a while after driving has started. In such
cases, turn the LDA system off and turn it on again after normal temperature
returns. When the temperature in the cabin decreases and the temperature around
the camera sensor becomes suitable for its operation, the functions will begin to
operate.
■Warning lights and messages for LDA
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 700)
CAUTION
■Before using the LDA system
This system provides information to the driver in accordance with the road geome-
try and the driving conditions. Be aware of your surroundings at all times, correct
the driving path while driving appropriately and be responsible for your own safety.
This system operates by using the camera to identify lane markers when the LDA
switch is on and the vehicle is being driven at the system operating speed.
Operation may be temporarily suspended if the camera cannot recognize the lane
markers or if the system cannot operate due to the road environment or driving
conditions. Also, since an alarm may sound unnecessarily if the lane markers cannot
be correctly identified, make sure to drive responsibly even while the system is
operating.
If a malfunction occurs in the system, the driver will be alerted by a buzzer and a dis-
play, and LDA operation will be temporarily suspended. However, this does not
present a problem to normal driving.
If the alert is displayed even after restarting the engine, have your vehicle inspected
by your Lexus dealer.

NOTICE
■Camera sensor
●Keep the windshield clean at all times.
LDA performance may deteriorate due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not subject the camera sensor to strong impact or force, and do not disas-
semble the camera sensor.
●Do not change the installation position of the camera sensor or remove it. The
direction of the camera sensor is precisely adjusted.
●When it is cold, using the heater with air blowing to the feet may cause the upper
part of the windshield to fog up. This will have a negative effect on the images. In
such a case, use the windshield defogger to provide warm, dry air to the wind-
shield.
●Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield as lane
markings by mistake.
●Do not scratch the camera lens, or let it get dirty.
●Do not attach stickers or other items to the windshield near the camera sensor.
●Adjust the inside rear view mirror correctly so that it does not interfere with the
camera sensor.
Observe the following to ensure that the
LDA system functions correctly.

PCS (Pre-Collision System)∗
∗: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact and injuries to occupants as well as
vehicle damage.
■ Pre-collision seat belts (front seat belts only)
If the system detects that a collision is unavoidable, the system will
retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. ( →P. 8 7 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
■ Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer. If
the system determines that a collision is unavoidable, the brakes are
automatically applied to reduce the collision speed. Pre-collision
braking can be disabled using the pre-collision braking off switch.

Radar sensorThe radar sensor detects vehicles
or other obstacles on or near the
road ahead and determines
whether a collision is imminent
based on the position, speed, and
heading of the obstacles.
Driver monitor sensor (if equipped)The driver monitor sensor detects
the direction the driver is facing.
The system determines whether
the driver is facing forward.
