Stop Start Overview
The 2013 MY Fusion will incorporate Stop Start. Stop-Start will automatically turn off the engine when the vehicle is stopped, such as at traffic lights, to avoid fuel waste due to unnecessary engine idle. Upon brake pedal release, the engine will automatically restart offering normal vehicle response. The vehicle may not turn off the engine when stopped depending on customer comfort settings or vehicle conditions.
The benefits are improved fuel economy and reduced exhaust emissions. Stop Start affects many components and subsystems in the vehicle as shown in the diagram below.
