Stop & Start - CITROËN C4 Picasso Owner's Handbook Manual

Driving
Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The
engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Perfect 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), when you place the gear
lever in neutral, and you release the clutch
pedal,
- with an electronic gearbox, at speeds
below 5 mph (8 km/h), when you press the
brake pedal or place the gear selector lever
in position N ,
- with an automatic gearbox, with the
vehicle stationary, when you press the
brake pedal or place the gear selector lever
in position N.
If your vehicle is fitted with the system, a time
counter calculates the sum of the periods in
STOP mode during a journey. It resets itself to
zero every time the ignition is switched on with
the START/STOP button.

For your comfort, during parking
manoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the START/STOP button.
Special cases: STOP mode not
available
STOP mode is not invoked when:
- the driver's door is open,
- the driver's seat belt is not fastened,
- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start using
the START/STOP button,
- the electric parking brake is applied or
being applied,
- the engine is needed to maintain a
comfortable temperature in the passenger
compartment,
- demisting is active,
- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
In this case, the "ECO" warning lamp
flashes for a few seconds then goes
off.
This operation is perfectly normal.
