Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a CITROËN
dealer or a
qualified workshop.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release terminals)
and that the connections are clean.
For more information and the precautions
to take before starting work on the 12 V
battery , refer to the corresponding
section.
Versions equipped with Stop & Start are
fitted with a
12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a
CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary .
Passenger compartment
filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary.
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is signalled by the temporary
illumination of this warning lamp
accompanied by a message warning
of the risk of the filter clogging up.
Traffic conditions permitting, regenerate
the filter by driving at a
speed of at least
37

mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a

low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
On a

new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.

12 V battery
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric 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 remote control batteries and
vehicle batteries to a
special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a
well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.
Access to the battery
The battery (-) terminal is not accessible.
A remote earth point is located on the upper
part of the bonnet (next to the battery).
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a
battery booster.
Never try to start the engine by connecting
a
battery charger.
Never use a
24 V or higher battery
b o o s t e r.
Check beforehand that the backup
battery has a
nominal voltage of 12 V and
a
capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, etc.).
Ensure that the jump lead cables do not
pass close to moving parts of the engine
(cooling fan, belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
The battery is located under the bonnet.
For access to the (+) terminal:
F

r

elease the bonnet using the interior lever,
then the exterior safety catch,
F

r

aise the bonnet and secure it with its stay,
F

l

ift the plastic cover for access to the (+)
terminal.

A
llow the engine to run for at least
30
minutes, by driving or with the vehicle
stationary, so that the battery reaches an
adequate state of charge.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Charging the battery using
a battery charger
For optimum ser vice life of the battery, it is
essential to maintain an adequate state of
charge. If you wish to charge your vehicle's battery
yourself, use only a
charger compatible
with lead-acid batteries with a nominal
voltage of 12 V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.

journeys,
-
i
f the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.

Disconnecting the battery
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of ser vice for a long
period.

of explosion!
If the battery has frozen, have it checked
by a
CITROËN dealer or by a qualified
workshop who will check that the internal
components have not been damaged and
that the container has not cracked, which
would mean a
risk of toxic and corrosive
acid leaking.

A
t the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A .
If this label is present, it is essential to
use only a 12 V charger to avoid causing
irreversible damage to the electrical
components related to the Stop & Start
system. Before disconnecting the battery:
F
c
lose all openings (doors, boot, windows,
roof),
F
s
witch off all electrical consumers (audio
system, wipers, lighting, etc.).

Reconnecting the (+) terminalDo not force the lever as locking will not
be possible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection of the
battery
Following reconnection of the battery, switch on
the ignition and wait 1 minute before starting to
permit initialisation of the electronic systems. If
minor problems nevertheless persist following
this operation, contact a
CITROËN dealer or
a


qualified workshop. Versions equipped with Stop & Start are
fitted with a
12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a

continuous
period of immobilisation of the vehicle,
a period which depends on the exterior
temperature and the state of charge of the
battery (up to about 8 hours).
