STARTING AND DRIVING CAUTION D Do not rely solely on the pre-collision safety system to avoid accidents. Your safe and attentive driving practices are still the best way to avoid accidents and you are always responsible for the operation of the vehicle and the safety of your passengers. When driving, always pay attention to the surrounding conditions and the course you are driving. D The pre-collision sensor's collision detection performance is limited. The sensor is able to detect a forward object within 10 degrees on either left or right side. If it is out of the range, or if there is no or weak millimeter wave reflection, the sensor could not detect the object and the system does not work properly. D Even if the pre-collision safety is operative in an unavoidable collision, unless the seat belts are worn and the brake pedal is depressed, the pre-collision seat belts and pre-collision brake assist system will not work. NOTICE Even if there is no object with which your vehicle may collide, the pre-collision safety system may be activated as follows: D The pre-collision seat belts work to quickly draw back the front seat belts by the retractors (pre-collision seat belts). D The pre-collision brake assist system works to apply more powerful braking than normal braking. 374
