Stop & Start

The Stop & Start function puts the engine on standby – STOP mode – during vehicle stopping phases (e.g. at red lights, in traffic jams).

The engine restarts automatically – START mode – as soon as the driver shows the intention to move off.

The function is designed to reduce fuel consumption, pollutant gas emissions and noise levels when stationary, mainly in urban driving.

The function does not change the vehicle's features, in particular braking.

Deactivation / Reactivation

The function is activated by default when the ignition is switched on.

To deactivate / reactivate the function:

► Press the button.

A message in the instrument panel confirms the change of status.

When the function is deactivated, the orange warning light is on; if the engine was on standby, it restarts immediately.
