STARTING AND DRIVING Precaution for pre−collision safety system It should be noted that the pre−collision sensor may detect the following as the objects with which your vehicle might collide, and the pre−collision safety may operate, even though there is no possibility of collision. D When traveling through a curve, there is an object on the edge of the road. D When traveling through a curve, another vehicle is passing from the opposite direction. D When traveling across a narrow iron bridge. D When there is a metallic object on the road. D When there is a steel plate on the road at a construction site. D When there is a bump on the road. D When waiting to turn to the left in an intersection, and another vehicle is passing from the opposite direction. D If your vehicle approaches another vehicle ahead very quickly. 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. 379
