CITROËN C4 Owner's Handbook Manual page 166

STOP & START
The Stop & Start system puts the en-
gine temporarily into standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine 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 en-
gine goes into standby automatically:
- with a manual gearbox , at speeds
9
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal,
- with an electronic gearbox , at a
speed below 5 mph (8 km/h), when
you press the brake pedal or put the
gear lever into position N .

If your vehicle is fi tted with
the system, a time coun-
ter calculates the sum of
the periods in STOP mode
d uring a journey. It resets itself to zero
every time the ignition is switched on
with the key.
With an electronic gearbox, for
your comfort during
maoeuvres, 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 braking, power steering, for
example.
Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.
Special cases: STOP mode
unavailable
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 electric parking brake is applied
parking
or being applied,
- the engine is needed to maintain a
comfortable temperature in the pas-
senger compartment,
- demisting is active,
- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case, the "ECO" warn-
ing lamp fl ashes for a few sec-
onds, then goes off.
This operation is perfectly normal.
