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 up per part of the scre en even if the dis-
play setting has been set to off.●
Vehicles with a navigation system (12.3-inch display): If the intuit ive 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 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 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.

Additionally, if the object becomes no longer in the traveling directio n 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 Cleara nce 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.
