Lexus RX Owners Manual (RX450h): Intelligent 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 accidental accelerator pedal operation, the vehicle moving the unintended direction due to the wrong shift position being selected, or while parking or traveling at low speeds, the sensors stationary detect objects, such as a wall, in the traveling direction of the vehicle, and the system operates to lessen an impact with a stationary object and reduce the resulting collision damage.

Examples of system operation

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
