Stop & Start - CITROËN DS3 Handbook

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:
- with a manual gearbox, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral, and you release the
clutch pedal.
- with a 5 or 6-speed electronic gearbox,
when stationary or at speeds below 5 mph
(8 km/h) (depending on version), when you
press the brake pedal or put the gear lever
in position N.
A time counter calculates the sum
of the periods in STOP mode
during a journey. It rests itself
to zero every time the ignition is
switched on with the key.
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 key.
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 key,
- 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.
The "EcO" warning lamp flashes for
a few seconds then goes off.
This operation is perfectly normal.
