The vehicle constantly monitors the roadway in front of the vehicle and identifies and tracks pedestrians on an interior display. If the system determines a likely impact, it will automatically take preventative steps to avoid hitting the pedestrian. The vehicle is equipped with a camera that displays an image of the area behind the vehicle on an interior display. A head-up display projects gauge (speed, RPM, etc.) information onto the inside of the windshield just below the driver's line of sight. The vehicle is equipped with sensors which compare vehicle speed to available distance to the vehicle ahead. If the speed exceeds the required distance to stop before colliding with the vehicle ahead, the brakes are automatically readied for maximum braking force once the driver applies the brakes.Technology and Telematics Mobile devices can wirelessly connect to the internet through the vehicle's private mobile network.
