NOTICE
■When using Intuitive parking assist
In the following situations, the system may not function correctly due t\
o a
sensor malfunction etc. Have the vehicle checked by your Toyota dealer.
●Intuitive parking assist operation display flashes, and a beep sounds when
no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows up and remains on without a beep.
● If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow 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.

Intelligent Clearance Sonar
The system operates in the following situations when an obstacle is
detected in the traveling direction of the vehicle.
◆The vehicle is driven at low speeds and the brake pedal is not
depressed, or is depressed too late
◆The accelerator pedal is depressed too far
: If equipped
When a collision may occur with an obstacle while parking or
traveling at low speeds, when the vehicle suddenly moves for-
ward due to mistaken accelerator pedal operation, or when the
vehicle moves due to the wrong shift position being selected,
the sensors detect obstacles to the front or rear in the traveling
direction of the vehicle, and the system operates to lessen
impact with obstacles such as walls, and reduce resulting dam-
age.

The Intelligent Clearance Sonar can be enabled/disabled on
screen ( P. 139) of the multi-information display.
When the Intelligent Clearance
Sonar function is OFF, the ICS
OFF indicator illuminates.
When the Intelligent Clearance Sonar function is switched OFF, system
operation does not resume until the function is switched back ON through
the settings screen on the multi-information display. (System operation
does not resume by operating the power switch.)

When the Intelligent Clearance Sonar function detects an obstacle
with a probability of collision, hybr id system output is restricted to
restrain an increase in vehicle spe ed. (Hybrid system output restric-
tion control: A)
Furthermore, when the accelerato r pedal continues to be depressed,
the brakes are applied to reduce t he vehicle speed. (Brake control: B)

■Operation starting conditions
When the ICS OFF indi cator is not illuminated or flashing ( P. 356,
665) and all of the fo llowing conditions are met, the system operates.
Hybrid system output restriction control
● The Intelligent Clearance Sonar is on.
● The vehicle speed is 10 mph (15 km/h) or less.
● There is an obstacle in the traveling direction of the vehicle (6
to 13 ft. [2 to 4 m ahead]).
● The system determined that a stronger-than-normal brake
operation was necessar y to avoid a collision.
Brake control
●Hybrid system output restrict ion control is being performed.
● The system determined that an emergency brake operation
was necessary to avoid a collision.
■Operation ending conditions
In any of the following situations, the system stops operating.
Hybrid system output restriction control
● The Intelligent Clearance Sonar function has been turned off
(stopped).
● The collision became avoidable with normal brake operation.
● The obstacle is no longer in the traveling direction of the vehi-
cle (6 to 13 ft. [2 to 4 m ahead]).
Brake control
●The Intelligent Clearance Sonar function has been turned off
(stopped).
● Approximately 2 seconds elapsed after the vehicle was
stopped by brake control.
● The brake pedal was depressed after the vehicle was stopped
by brake control.
● The obstacle is no longer in the traveling direction of the vehi-
cle (6 to 13 ft. [2 to 4 m ahead]).

When the hybrid system output restriction control or brake control
operates, the buzzer sounds and a message is displayed on the multi-
information display to alert the driver.
Depending on the situation, output restriction control operates to either
limit acceleration or restrict output as much as possible.
