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
sensors may not be able to detect
obstacles that are extremely close
to the vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

■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

■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.

Indication on the multi-information display
While the LDA system is on, a lane line display is shown on the multi-
information display to inform the driver that the LDA system is on.
●When thin lines are shown:
Lane markers are not recog-
nized by the system, or the LDA
system is temporarily canceled.
● When solid lane lines are
shown: The LDA system is
active.

■The LDA system can be operated when
●The “LDA” switch is on.
●Vehicle speed is between 30 mph and 125 mph (48 km/h and 200 km/h).
■Temporary cancellation of the LDA system
If any of the following occurs, the LDA system will be temporarily canceled. The
functions will resume after the necessary operating conditions have returned.
●The turn signal lever is operated.
●The brake pedal is depressed.
●The vehicle speed deviates from the operating range of the LDA system.
●The lane lines cannot be recognized while driving.
●The wiper operates continuously.
●When the lane departure warning function is activated.
Once the lane departure warning function is activated, it will be temporarily
canceled and resume a few seconds later.

■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.

CAUTION
■Turn the LDA off while driving in any of the following situations
Do not use LDA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with snow tires, tire chains, a spare tire, or similar equipment.
●When driving with non-standard parts or aftermarket equipment installed
(including modified tires and suspensions, etc.).
●When towing a trailer.
●When there are objects or structures along the roadside that might be misinter-
preted as lane markers (such as guardrails, curbs, reflector posts, etc.).
●When there is snow in the wheel tracks of the road.
●When there are shadows on the road running parallel with lane markers, or if a
shadow is covering the lane markers.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road.
●When driving in a lane other than the driving or passing lanes on a freeway or
highway.
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane.
