Optimum Shift Indicator.
Optimal and perfectly-timed gear changes can help save fuel, particularly in urban traffic and over long distances.
Optimal gear changes, less fuel consumption – the engine’s electronics system identifies the most efficient gear, based on road conditions and engine speed. An arrow lights up in the Info Display to show you when it would be more efficient to shift into a higher or lower gear. The system also recognises when you are accelerating fast, and will delay its recommendation accordingly until the engine speed is back up. Comparative tests have shown that vehicles with the Optimum Shift Indicator use around four per cent less fuel.
