336 4-5. Using the driving support systems
RX350/RX350L_U The system will operate in situations such as the following if a stationary object is
detected in the traveling direction of the vehicle.
◆ When traveling at a low speed and the brake pedal is not depressed, or is
depressed late
 : If equippedIntelligent Clearance Sonar (ICS) If a collision with a wall or other stationary object may occur due to the vehicle
suddenly moving forward due to an ac cidental accelerator pedal operation,
the vehicle moving the unintended dire ction due to the wrong shift position
being selected, or while parking or trav eling at low speeds, the sensors detect
stationary objects, such as a wall, in th e traveling direction of the vehicle, and
the system operates to lessen an impact with a stationary object and reduce
the resulting collision damage.

338 4-5. Using the driving support systems
RX350/RX350L_U If a rear radar sensor detects a vehicle ap proaching from the right or left at the
rear of the vehicle and the system determ ines that the possibility of a collision is
high, this function will perform brake control to reduce the likelihood of an
impact with the approaching vehicle. ■
Examples of system operation
This function will operate in situations such as the following if a vehicle is
detected in the traveling direction of the vehicle.
◆ When reversing, a vehicle is approaching and the brake pedal is not
depressed, or is depressed lateRear Cross Traffic Auto Brake function (if equipped)

To re-enable the system when it was disabl ed, select on the multi-information dis-
play, select “ICS” and then “On”. If disabled using this method, the system will not be
re-enabled by turning the engine switch off and then to IGNITION ON mode.Types of sensors 

RX350/RX350L_U If the engine output restriction contro l 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 co ntrol will operate to either
limit acceleration or restrict output as much as possible.

Driving
RX350/RX350L_U If the Intelligent Clearance Sonar function detects that a collision with a wall or
other stationary object is possible, the en gine output will be restricted to restrain
any increase in the vehicle speed. (Eng ine output restriction control: See A
below.)
Additionally, if the accelerator pedal continues to be depressed, the brakes will
be applied automatically to reduce the vehicle speed. (Brake control: See B
below.)Intelligent Clearance Sonar function

The Intelligent Clearance Sonar function will operate when
The function will operate when the ICS O FF indicator is not illuminated or flashing
(  P. 339, 347) and all of the following conditions are met: ●
Engine output restriction control
• The Intelligent Clearance Sonar system is enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• There is a stationary object in the traveling direction of the vehicle and 6 to 13 ft. (2
to 4 m) away.
• The system determines that a stronger-t han-normal brake operation is necessary to
avoid a collision. ●
Brake control
• Engine output restriction control is operating.
• The system determines that an emergenc y brake operation is necessary to avoid a
collision.■
The Intelligent Clearance Sonar fu nction 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 Son ar system is disabled.
• The collision becomes avoidable with normal brake operation.
• The stationary object is no lo nger 6 to 13 ft. (2 to 4 m) away in the traveling direction
of the vehicle. ●
Brake control
• The Intelligent Clearance Son ar 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 stationary object is no lo nger 6 to 13 ft. (2 to 4 m) away in the traveling direction
of the vehicle.■
Detection range of the Intellig ent Clearance Sonar function
The detection range of the Intelligent Cleara nce Sonar function differs from the detec-
tion range of the intu itive parking assist. (  P. 331)
Therefore, even if the intuit ive parking assist detects an object and provides a warning,
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 di sabled and the ICS OFF indicator will illumi-
nate.
