Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams,...).
The engine restarts automatically – START
mode – as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Operation
Going into engine STOP mode
The " ECO" warning lamp comes on in
the instrument panel and the engine
goes into standby automatically:
- with a manual gearbox , at speeds below
12 mph (20 km/h) or when the vehicle is
stationary with the PureTech 130 petrol and
BlueHDi 115 and 120 Diesel versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

W
ith an automatic gearbox , when the
vehicle is stationary and when you press
the brake pedal or put the gear selector in
position N . If your vehicle is fitted with this
system, a time counter calculates
the time spent in STOP mode
during a journey. It resets to
zero every time the ignition is
switched on with the key or the
"START/STOP" button.
STOP mode does not affect the operation
of vehicle systems such as braking, power
steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition with
