DRIVING
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 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 consump-
tion and exhaust emissions as well
as the noise level when stationary.

Operation



- with the electronic gearbox
system
, at speeds below 4 mph
(6 km/h), press the brake pedal or
put the gear lever in position N
.
Going into engine STOP mode

The "ECO"
warning lamp comes
on in the instrument panel and
the engine goes into standby:
If your vehicle is fi tted
with the system, 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
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the func-
tionality of the vehicle, such as for ex-
ample, 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
In this case, the "ECO"

warning lamp fl ashes for a
few seconds then goes off.

This operation is perfectly normal.
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 ap-
plied 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.

the electronic gearbox
sys-
tem
:


Special cases: START invoked
automatically
In this case the "ECO"

warning lamp fl ashes for a
few seconds, then goes off.

This operation is perfectly normal.

START mode is invoked automati-
cally when:


- the driver's door is open,

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

- the speed of the vehicle exceeds
7 mph (11 km/h) with the elec-
tronic gearbox system,

- the electric parking brake is being
applied,

- some special conditions (battery
charge, engine temperature,
braking assistance, ambient tem-
perature...) where the engine is
needed for control of a system. At any time, press the "ECO
OFF"
switch to deactivate the sys-
tem.
This is confi rmed by the switch warn-
ing lamp coming on accompanied by
a message in the screen.
Deactivation


If the system has been deactivated
in STOP mode, the engine restarts
immediately.


The system is reactivated auto-
matically at every new start using
the key.



Reactivation

DRIVING
In the event of a fault with the sys-
tem, the "ECO OFF"
switch warning
lamp fl ashes then comes on con-
tinuously.
Have it checked by a CITROËN
dealer or a qualifi ed workshop.
In the event of a fault in STOP mode,
the vehicle may stall: all the instru-
ment panel warning lamps come on.
It is then necessary to switch off the
ignition and start the engine again
using the key.


Operating fault


The Stop & Start system
makes use of advanced tech-
nology. For any work on the sys-
tem go to a qualifi ed workshop with
the skills and equipment required,
which a CITROËN dealer is able to
provide.

Before doing anything under
the bonnet, deactivate the
Stop & Start system to avoid
any risk of injury resulting from au-
tomatic operation of START mode.


Maintenance

This system requires a 12 V battery
with a special specifi cation and tech-
nology (reference numbers available
from CITROËN dealers).
Fitting a battery not listed by
CITROËN introduces the risk of mal-
function of the system.
To charge the battery, use a 12 V
charger and observe the polarity.

BONNET

Opening


)
At the front of the bonnet, lift the
safety catch B
and raise the bonnet.


)
Unclip the stay C
from its housing
and pivot it to insert it in the notch D

indicated by a yellow arrow.

)
Fix the stay in the notch to hold
the bonnet open.


Closing



)
Take the stay out of the support
notch.

)
Clip the stay in its housing.

)
Lower the bonnet then slam it
fi rmly at the end of its travel.

)
Pull on the bonnet to check that
it is fully closed.
When the engine is hot, handle the
safety catch and bonnet stay with
care (risk of burns).
The location of the interior release
lever prevents opening of the bon-
net while the left hand front door is
closed.
This operation must only be carried
out when the vehicle is stationary.
Avoid opening the bonnet in strong
winds.


)
Open the left hand front door.

)
Pull the interior bonnet release

CHECKS






CHECKS












12 V battery

The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical information"
section for details of the precautions
to be taken before disconnecting the
battery and following its reconnection.










Particle filter system (Diesel)

Complementary to the catalytic con-
verter, this fi lter makes an active
contribution to the preservation of air
quality by trapping unburnt pollutant
particles. Black exhaust fumes are
thus no longer emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of blockage, a mes-
sage appears in the instrument
panel screen, accompanied by an
audible signal and illumination of
the service warning lamp.
This alert tells you that the par-
ticle fi lter is approaching satura-
tion (in conditions of urban driving
of exceptionally long duration: low
speeds, traffi c jams etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, contact a CITROËN
dealer or a qualifi ed workshop.







The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and specifi -
cation. The involvement of a CITROËN
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery.


Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualifi ed
workshop.




















Air filter and passenger compartment filter


Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), replace them twice as often if
necessary
.
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesirable
odours.

Replace the oil fi lter each
time the engine oil is
changed.













Oil filter

Refer to the servicing booklet for de-
tails of the replacement interval for
this component.

PRACTICAL INFORMATION
BATTERY
Procedure for charging your battery
when it is fl at or for starting the en-
gine using another battery.

Access to the battery

V6 HDi engine

The battery is located under the bonnet.

For access to it:


)
open the bonnet using the interi-
or release lever, then the exterior
safety catch,

)
secure the bonnet stay,

)
remove the plastic cover to gain
access to the two terminals,

)
unclip the fusebox to remove the
battery, if necessary. The battery is located in the boot
under the left-hand wing trim.
For access to it:


)
open the boot,

)
open the fl ap and remove the
battery.







The presence of this label, in
particular with the Stop & Start
system, indicates the use of a
12 V lead-acid battery with special
technology and specifi cation; the
involvement of a CITROËN dealer
or a qualifi ed workshop is essential
when replacing or disconnecting
the battery.
Failure to observe this recommen-
dation may cause premature wear
of the battery.

After refi tting the battery by a
CITROËN dealer or a qualifi ed
workshop, the Stop & Start system
will only be active after a continu-
ous period of immobilisation of the
vehicle, a period which depends
on the climatic conditions and the
state of charge of the battery (up to
about 8 hours).
