Toyota Camry Intelligent Clearance Sonar

    Toyota Camry Intelligent Clearance Sonar (ICS) is an innovative safety feature that makes navigating tight parking spaces simple and safe at low speeds. If a collision with an 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 detect objects, such as a wall, in the traveling direction of the vehicle, and the system operates to lessen an impact with an object and reduce the resulting damage.

    Examples of system operation

    The system will operate in situations such as the following if an 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

    When the accelerator pedal is depressed excessively

    When the vehicle moves in the unintended direction due to the wrong shift position being selected

    Rear Cross Traffic Auto Brake function

    If a radar sensor detects a vehicle approaching from the right or left at the rear of the vehicle and a collision may occur, this function will perform brake control to reduce the likelihood of an impact with the approaching vehicle.

    Examples of system operation

    The system will operate in situations such as the following if an object 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 late

    Types of sensors

    1. Front corner sensors
    2. Front center sensors
    3. Rear corner sensors

    Intelligent Clearance Sonar function

    If the Intelligent Clearance Sonar function detects that a collision with an object is possible, the engine output will be restricted to restrain any increase in the vehicle speed. (Engine 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.)

    1. Accelerator pedal
    2. Brake pedal
    3. Engine output
    4. Braking force
    5. Start of control
    6. High possibility of a collision
    7. Extremely high possibility of a collision

    The Intelligent Clearance Sonar function will operate when

    The function will operate when the ICS OFF indicator is not illuminated or flashing 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 an object in the traveling direction of the vehicle and 6 to 13 ft. (2 to 4 m) away.
      • The system determines that a stronger-than-normal brake operation is necessary to avoid 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 any 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 6 to 13 ft. (2 to 4 m) 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 detection range of the intuitive parking assist.

    Therefore, even if the intuitive 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 disabled and the ICS OFF indicator will illuminate.

    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. 335), 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 changes (such as changing from moving forward to backing up, or from backing up to moving forward), the system will be re-enabled automatically.

    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

    To initialize the system, drive the vehicle straight ahead for 5 seconds or more at a speed of approximately 22 mph (35 km/h) or more.

    If “ICS Unavailable” is displayed on the multi-information display and the ICS OFF indicator is flashing

    Initialization may not have been performed after a battery terminal was disconnected and reconnected. Initialize the system.

    If this message continues to be displayed even after initialization, have the vehicle inspected by your Toyota dealer.

    If “ICS Unavailable” and “Parking Assist Unavailable Clean Parking Assist Sensor” are displayed on the multi-information display and the ICS OFF indicator is flashing

    • A sensor may be covered with ice, snow, dirt, etc. In this case, remove the ice, snow, dirt, etc., from the sensor to return the system to normal. If this message is shown even after removing dirt from the sensor, or shown when the sensor was not dirty to begin with, have the vehicle inspected at your Toyota dealer.
    • A sensor may be frozen. Once the ice melts, the system will return to normal.
    • Water may be continuously flowing over the sensor surface, such as in a heavy rain. When the system determines that it is normal, the system will return to normal.

    WARNING

    Limitations of the Intelligent Clearance Sonar system

    Do not overly rely on the system, as doing so may lead to an accident.
