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
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal, If your vehicle is fi tted with
the system, a time counter
calculates the sum of the
periods in STOP mode dur-
ing a journey. It resets itself to zero ev-
ery time the ignition is switched on with
the key.

- with the 6-speed electronic gear-
box system
, at a speed below
5 mph (8 km/h), when you press the
brake pedal or put the gear lever
into position N
. With the electronic gearbox sys-
tem, for your comfort during park-
ing 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.
Special cases: STOP mode
unavailable
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fas-
tened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start
using the key,

- the electric parking brake is applied
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"
warning
lamp fl ashes for a few seconds,
then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

This operation is perfectly normal.

Going into engine START mode
At any time, press the "ECO OFF"

switch to deactivate the system.
This is confi rmed by the switch warning
lamp coming on accompanied by the
display of a message.
Special cases: START invoked
automatically
If the system has been deacti-
vated in STOP mode, the engine
restarts immediately. The "ECO"
warning lamp goes
off and the engine starts auto-
matically:


- with a manual gearbox
, when you
fully
depress the clutch pedal,

- with the 6-speed electronic gear-
box system
:


●
gear lever in position A
or M
, when
you release the brake pedal,

●
or gear lever in position N
and the
brake pedal released, when you
move the gear lever to position A

or M
,

●
or when you engage reverse gear.

For safety reasons or to ensure smooth
operation, START mode is invoked au-
tomatically when:


- you open the driver's door,

- you unfasten the driver's seat belt,

- the speed of the vehicle exceeds
15 mph (25 km/h) with a manual
gearbox or 7 mph (11 km/h) with the
6-speed electronic gearbox system,

- the electric parking brake is being
applied,

- 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"
warning
lamp fl ashes for few seconds,
then goes off.
With a manual gearbox in STOP
mode, if a gear is engaged with-
out fully depressing the clutch
pedal, a warning lamp comes
on or an alert message is dis-
played asking you to depress
the clutch pedal to restart the
engine.



Reactivation

Press the "ECO OFF"
switch again.
The system is active again; this is con-
fi rmed by the switch warning lamp going

Maintenance

In the event of a malfunction with the
system, the "ECO OFF"
switch warn-
ing lamp fl ashes, then comes on con-
tinuously.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.


Operating fault

Before doing anything under the
bonnet, deactivate the Stop &
Start system to avoid any risk of
injury resulting from automatic
operation of START mode.
This system requires a specifi c battery
with a special specifi cation and techno-
logy (reference numbers available from
a CITROËN dealer or a qualifi ed work-
shop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the
system.
The Stop & Start system makes
use of advanced technology. All
work on this type of battery must
be done only by a CITROËN
dealer or a qualifi ed workshop.
In the event of a fault in STOP
mode, the vehicle may stall. All
of the instrument panel warning
lamps come on.
Depending on version, an alert
message may also be displayed
asking you to put the gear lever
into position N
and put your foot
on the brake pedal.
It is then necessary to switch off
the ignition, then restart the en-
gine using the key.
