■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the foll
owing distance of the obstacle, the
buzzer sounds continuously. • Front corner sensors: Approximately 1.0 ft. (30 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. If on e or both come within the above dis-
tances, the beep will repeat a long tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.6 ft. (50 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.

■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is
in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h). (At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system, Lexus parking assist
monitor or Multi-terrain Monitor is in use, the warning indicator will appear in the upper
corner of the screen even if the display setting has been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surround ing 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 the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning co nsiderably 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.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• 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 (lowered 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 a sensor to be closer than they are.

CAUTION
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driv
en safely and possibly
cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction times are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi-
cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by your Lexus dealer.
●A buzzer does not sound when you turn the intuitive parking assist on.
●The intuitive parking assist operation disp lay flashes, and a buzzer sounds when no
obstacles are detected.
●If the area around a sensor collides with so mething, or is subjected to strong impact.
●If the bumper collides with something.
●If the display shows continuously without a beep.
●If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, sn ow or mud on the sensor, it is likely that the
sensor is malfunctioning.
■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.
