An engine that is not running does not need any fuel. This truism helps the Mercedes-Benz Sprinter to save fuel and thereby reduce its environmental impact. If the vehicle is stationary with the engine idling and the transmission in neutral for more than three seconds, the engine is automatically switched off. As soon as the driver depresses the clutch pedal again, the engine re-starts.

On average, the amount saved will probably be somewhere between five and eight percent. The system performs to best advantage in urban use involving frequent stops in traffic queues or at traffic lights.

The only difference is that some front pads don’t have the wear indicator so you will need to tie the cable back out of the way if not required.
