Auto Start/Stop function

The Auto Start/Stop function of your vehicle automatically switches off the engine during a stop.

If the engine is switched off and then restarted rather than leaving the engine running constantly, fuel consumption and emissions are reduced.

Savings can begin within a few seconds of switching off the engine.

Using this system can cause certain components of the vehicle to become worn prematurely.

Iin addition, fuel consumption is also determined by other factors, such as driving style, road conditions, maintenance or environmental factors.
