國外官網說 ES的LSS+: PRE-COLLISION SYSTEM* WITH PEDESTRIAN DETECTION* This system is engineered to detect vehicles or pedestrians in the path of your Lexus under certain conditions. Should the system detect a pedestrian or determine a frontal collision is imminent, it’s designed to activate an audible and visual alert while automatically preparing Brake Assist* for increased braking response. If the driver does not brake in time, the system is designed to automatically begin braking before impact and, in some cases, can even brake the vehicle to a stop.
