The available Advanced Pre-Collision System [1] in the LS 600h L features the world's first Driver Attention Monitor. Using an infrared camera that is designed to monitor the direction of the driver's face while the vehicle is in motion, the system can sound a series of warning beeps and, if necessary, briefly apply the brakes to alert the driver if an object is detected ahead while the driver is facing away from the road. Once a collision is determined to be unavoidable, the system then preps the Brake Assist [2] for increased braking effectiveness once the brakes are applied and retracts the front seatbelts to help reduce collision damage.
