■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in other than P.
• The vehicle speed is less than about 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 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
●Vehicles with a Lexus Display Audio system/navigation system (8-inch display): When
an object is detected while the Lexus parking assist monito r or panoramic view monitor
is in use, the warning indicator will appear in the upper part of the screen even if the dis-
play setting has been set to off.
●Vehicles with a navigation system (12.3-inch display): If the intuitive parking assist dis-
play is set to on, detected objects will also be displayed on the panoramic view monitor.
For details, refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.
■Sensor detectio n information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an object. 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 the 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 considerably to one side.
• When a sensor or the area around a sensor is extremely hot or cold.
• 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 bumper or sensor re ceives a strong impact.
• If the vehicle is significantly tilted.
• 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 objects draw too close to the sensor.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there ar e instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

■Re-enabling the Intelligent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due to operation
of the Intelligent Clearance Sonar function, either enable the system again ( P. 339), or
turn the engine switch off and th en back to IGNITION ON mode.
Additionally, if the object becomes no longer in the traveling direction of the vehicle or if
the traveling direction of the vehicle change s (such as changing from moving forward to
backing up, or from backing up to moving fo rward), the system will be re-enabled auto-
matically.
■Objects that the Intelligent Clearance Sonar function may not detect
The sensors may not be able to detect certain objects, such as the following.
●Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic waves.
(People may also not be detected depending on the type of clothing they are wearing.)
●Objects which are not perpendicular to the ground, are not perpendicular to the travel-
ing direction of the vehicle, are uneven or are waving.
●Low objects
●Thin objects such as wires, fences, ropes and signposts
●Objects that are extremely close to the bumper
■Intuitive parking assist buzzer
Regardless of whether the in tuitive parking assist system is enabled or not ( P. 326), if
the Intelligent Clearance Sonar system is enabled ( P. 339), the front or rear sensors
detect an object and brake control is performed, the intuitive parking assist buzzer will
sound to notify the driver of the approximate distance to the object.

■Re-enabling the Rear Cross Traffic Auto Brake function
To re-enable the Rear Cross Traffic Auto Brake function when it is disabled during opera-
tion of the Rear Cross Traffic Auto Brake function, either enable the system again (P.
339), or turn the engine switch off and then back to IGNITION ON mode.
Additionally, if there is no longer a vehicle ap proaching from the right or left at the rear of
the vehicle, or if the traveling direction of the vehicle changes (such as changing from
moving forward to backing up or from backin g up to moving forward), the system will be
re-enabled automatically.
■Conditions under which the Rear Cross Traffic Auto Brake function will not detect a
vehicle
The Rear Cross Traffic Auto Brake function is not designed to detect the following types
of vehicles and/or objects:
●Vehicles approaching from directly behind
●Vehicles backing up in a parkin g space next to your vehicle
●Guardrails, walls, signs, parked vehi cles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking spaces next to your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or object may occur.
■RCTA function buzzer

Traffic Auto Brake function is enabled and brake control is performed, a buzzer will
sound to notify the driver.
●Vehicles that the sensors cannot detect due to
obstructions
●Vehicles which suddenly accelerate or decel-
erate near your vehicle
