A vehicle system has at least one sensor configured to output a range signal and a range-rate signal. The range signal represents a distance from a host vehicle to the front vehicle and the range-rate signal represents range-rate information of the front vehicle relative to the host vehicle. Following a determination that the driver of the vehicle is distracted, a processing device is configured to output an alarm signal based on the range signal and the range-rate signal. Preferably the front vehicle is moving away from the host vehicle after a stopping. This may be used in a stop-start system when the engine is turned off. The movement of the front vehicle may be used to predict power demand of the host.
