Start/stop function
With the start/stop function, the engine switches
Eco
off temporarily when the car has stopped e.g. at
drive mode in
traffic lights or in a traffic queue, and then starts
again automatically when the journey is resumed.
The start/stop function reduces fuel consump-
tion, which in turn contributes to reduced exhaust
emissions.
The system makes it possible to adopt an envi-
ronmentally-conscious driving style by allowing
the car to engine auto-stop when possible.
