■The Lexus parking assist-sensor 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 10 km/h (6 mph). (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 10 km/h (6 mph).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode. • The shift lever is in R.
■Lexus parking assist-sensor display
●Vehicles with a Lexus Display Audio system : When an obstacle is detected while the Lexus parking assist monitor is in use, the warning indicator will appear in the upperpart of the screen even if the display setting has been set to off.
●Vehicles with a navigation system: If the Lexu s parking assist-sensor display 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 detection 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 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 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.
• 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, airbrakes 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.
• Towing eyelets are installed. • 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 (low ered 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.

If the engine output restriction control or brake control operates, a buzzer will
sound and a message will be displayed on the multi-information display to alert
the driver.
Depending on the situation, engine output restriction control will operate to either limit acceleration or restrict output as much as possible.

If the Intelligent Clearance Sonar function detects that a collision with an object
is possible, the engine output will be re stricted to restrain any increase in the
vehicle speed. (Engine output restriction control: See A below.)
Additionally, if the accelerator pedal cont inues to be depressed, the brakes will
be applied automatically to reduce the vehicle speed. (Brake control: See B
below.)

■The Intelligent Clearance Sonar function will operate when
The function will operate when the ICS OFF indicator is not illuminated or flashing ( P. 383, 391) and all of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar system is enabled. • The vehicle speed is 15 km/h (10 mph) or less.• There is an object in the traveling directio n of the vehicle and 2 to 4 m (6 to 13 ft.)
away. • The system determines that a stronger-than-normal brake operation is necessary toavoid a collision.
●Brake control
• Engine output restriction control is operating.
• The system determines that an emergency brake operation is necessary to avoid a collision.
■The Intelligent Clearance Sonar function will stop operating when
The function will stop operating if an y of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar system is disabled.
• The collision becomes avoidable with normal brake operation. • The object is no longer 2 to 4 m (6 to 13 ft.) away in the traveling direction of thevehicle.
●Brake control
• The Intelligent Clearance Sonar system is disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake control. • The brake pedal is depressed after the vehicle is stopped by brake control.• The object is no longer 2 to 4 m (6 to 13 ft.) away in the traveling direction of the
vehicle.
■Detection range of the Intelligent Clearance Sonar function
The detection range of the Intelligent Clearance Sonar function differs from the detec-
tion range of the Lexus parking assist-sensor ( P. 375).
Therefore, even if the Lexus parking assist-s ensor detects an object and provides a warn- ing, the Intelligent Clearance Sonar function may not start operating.
■If the Intelligent Clearance Sonar function has operated
If the vehicle is stopped due to operation of the Intelligent Clearance Sonar function, the Intelligent Clearance Sonar system will be disa bled and the ICS OFF indicator will illumi-
nate.

■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. 383),
or turn the engine switch off and then 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 chan ges (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 traveling 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
■Lexus parking assist-sensor buzzer
Regardless of whether the Lexus parking as sist-sensor system is enabled or not (P. 375), if the Intelligent Clearance Sonar system is enabled ( P. 383), the front or rear sensors detect an object and brake control is performed, the Lexus parking assist-sensor
buzzer will sound to notify the driver of the approximate distance to the object.
