PRE-CRASH SAFETY SYSTEM


  1. OUTLINE


    1. Toyota Safety Sense


      1. Preventive safety package "Toyota Safety Sense" has been adopted to support the safety drive.

      2. System that are included in the "Toyota Safety Sense" are as follows:


        • PCS (Pre-crash Safety System)

        • Dynamic radar cruise control

        • LDA (Lane Departure Alert)

        • RSA (Rood Sing Assist)

        • AHB (Automatic High Beam)

        A01QFGGE01

    2. Pre-crash Safety System (PCS)


      1. Pre-crash safety system lessens the damage sustained in a collision by operating in unison with warning device and brake systems.

      2. The pre-crash Safety system detects the vehicle and pedestrian* in front of the vehicle based on both data from a forward recognition camera and millimeter wave radar sensor.

      3. If the pre-crash safety system determines that the possibility of a collision is high, pre-crash alarm control and pre-crash brake assist control is performed, and if a collision is unavoidable, pre-crash brake control will be performed in order to reduce the impact of the collision.


        • *: Except models for Russia

  2. PRECAUTION


    1. Toyota Safety Sense


      1. The "Toyota Safety sense", is designed to operate under the assumption that the driver will drive safely, and is designed to help reduce the impact to the occupants and the vehicle in the case of a collision.

      2. As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle's surroundings and driving safely.

    2. Limitations of the pre-crash safety system


      1. The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.

      2. Do not use the pre-crash safety system instead of normal braking operations under any circumstances. This system will not prevent collisions or lessen damage or injuries in every situation. Do not overly rely on this system. Failure to do so may lead to an accident, resulting in death or serious injury.

      3. Although this system is designed to help avoid and reduce the impact of a collision, its effectiveness may change according to various conditions, therefore the system may not always be able to achieve the same level of performance.

      4. Read the following conditions carefully. Do not overly rely on this system and always drive carefully.

    3. Pre-crash braking


      1. The pre-crash braking function may not operate if certain operations are performed by the driver. If the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the driver is taking evasive action and possibly prevent the pre-crash braking function from operating.

      2. In some situations, while the pre-crash braking function is operating, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steering wheel is turned and the system determines that the driver is taking evasive action.

      3. A large amount of braking force is applied while the pre-crash braking function is operating. Additionally, as the vehicle may creep after the pre-crash braking function has operated, the driver should depress the brake pedal as necessary.

      4. If the brake pedal is being depressed, the system may determine that the driver is taking evasive action and possibly delay the operation timing of the pre-crash braking function.

    4. Pedestrian detection* (Except model for Russia)


      1. The pre-crash safety system detects pedestrians based on the size, profile, and motion of a detected object. However, a pedestrian may not be detected depending on the surrounding brightness and the motion, posture, and angle of the detection object, preventing the system from operating properly.

        Tech Tips

        *: Depending on the region in which the vehicle was sold, the pedestrian detection function may not be available.

    5. When to disable the pre-crash safety system


      1. If the following situations, disable the system, as it may not operate properly, possibly leading to an accident:


        • When the vehicle is being towed

        • When your vehicle is towing another vehicle

        • When transporting the vehicle via truck, boat, train or similar means of transportation

        • When the vehicle is raised on a lift with the ignition switch on and the tires are allowed to rotate freely

        • When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tester, or when using an on vehicle wheel balancer

        • When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons

        • If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunction

        • When the vehicle is driven in a sporty manner or off road

        • When the tires are not properly inflated

        • When the tires are very worn
