Stop & Start

~4min read

Stop & Start temporarily puts the engine on standby - STOP mode - when the vehicle stops in traffic (red lights, congestion, etc.). The engine restarts automatically - START mode - as soon as you want to move off. Restarting is instant, quick and quiet.

Ideally suited to urban driving, Stop & Start reduces fuel consumption, pollutant emissions and noise levels when stationary.

and the engine switches to standby:

a timer records the total time spent in STOP mode during the journey. It resets each time the ignition is switched on with the key.

For your comfort, during parking manoeuvres, STOP mode is unavailable for a few seconds after reverse gear is disengaged. STOP mode does not affect vehicle functions such as braking, power steering... ! Never refuel when the engine is in STOP mode; always switch off the ignition with the key.
