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. It is then nec-
essary to switch off the ignition and
start the engine again using the
key.
Maintenance
Operating fault
Before doing anything un-
der the bonnet, deactivate
the Stop & Start system to
avoid any risk of injury resulting
from automatic operation of START
mode.
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
malfunction of the system.
To charge the battery, use a 12 V
charger and observe the polarity.
The Stop & Start system
makes use of advanced
technology. For any work
on the system go to a qualifi ed
workshop with the skills and equip-
ment required, which a CITROËN
dealer is able to provide.

12 V battery
The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly 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
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving
at very low speeds, you may oc-
casionally notice water vapour be-
ing emitted from the exhaust when
accelerating. This is of no conse-
quence to the running of the vehicle
or to the environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audible
signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally 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, consult a
CITROËN dealer or a qualifi ed
workshop.
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer or a qualifi ed workshop is
required when replacing or discon-
necting the battery. Failure to observe this recommen-
dation may shorten the life of 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
(refer to the "Engines"
section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.

PRACTICAL INFORMATION
12 V BATTERY
Procedure for starting the engine
using another battery or for charging
your fl at battery.
The Stop & Start battery does not
have to be disconnected for charging.
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 deal-
er or a qualifi ed workshop is essential
when replacing or disconnecting the
battery.
After refi tting the battery, the Stop &
Start system will only be active after
a continuous period of immobilisa-
tion of the vehicle, a period which
depends on the climatic conditions
and the state of charge of the bat-
tery (up to about 8 hours).

is switched off.
Check that the battery posts and
terminals are clean. If they are cov-
ered with sulphate (white or green
deposit), disconnect them and
clean them.
Batteries contain harmful
substances such as sul-
phuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in
any circumstances, be discarded
with household waste.
Take used cell batteries and vehi-
cle batteries to an authorised col-
lection point.

)
Once charging is complete, dis-
connect the charger cables in re-
verse order.
The charging operation
must be carried out in a
well ventilated area and
well away from naked fl ames and
sources of sparks, so as to avoid
any risk of explosion and fi re.
Do not try to charge a frozen bat-
tery; the battery must fi rst be
thawed out to avoid any risk of ex-
plosion. If the battery has frozen,
before charging, have it checked
by a CITROËN dealer or a quali-
fi ed workshop, who will ensure that
the internal components have not
been damaged and that the casing
is not cracked, which would intro-
duce the risk of a leak of toxic and
corrosive acid.
Charging the battery using
a battery charger
If the battery of your vehicle is fl at
or prior to taking the vehicle out of
service for an extended period, you
can charge the battery using a bat-
tery charger.
For information on the specifi cation
of battery chargers compatible with
your battery, refer to a CITROËN
dealer or a qualifi ed workshop.
It is recommended that the battery
be disconnected if the vehicle is not
be used for more than a month.
Reinitialisation after
reconnection
After any reconnection of the bat-
tery, switch on the ignition and wait
at least one minute before starting,
to allow time for the initialisation of
the electronic systems.
By referring to the corresponding
sections, you should set or initialise
the following systems yourself:
- the date and time,
- the anti-pinch on the driver's
electric window and the sunroof.
- the panoramic sunroof blind,
- the multifunction screen set-
tings,
- the audio system or navigation
system settings,
