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.

F Start the engine of the vehicle with the good battery and leave it running for a few
minutes.
F

O
perate the starter on the broken down
vehicle and let the engine run.
If the engine does not start straight away,
switch off the ignition and wait a
few moments
before trying again.
F

W
ait until the engine returns to idle then
disconnect the jump lead cables in the
reverse order.
F

R
efit the plastic cover to the (+) terminal, if
your vehicle has one.
F

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.
F

L

ift the plastic cover on the (+) terminal, if
your vehicle has one.
F

C

onnect the red cable to the (+) terminal of
flat battery A (at the metal elbow) then to
the (+) terminal of backup battery B or the
b o o s t e r.
F

C

onnect one end of the green or black
cable to the (-) terminal of backup battery
B or the booster (or an earth point on the
other vehicle).
F
C
onnect the other end of the green or black
cable to earth point C on the broken down
vehicle. In some circumstances it may be necessary to
charge the battery:
-

i
f you only use your vehicle for short
journeys,
-
i
f the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a breakdown

233
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.
Quick-release terminal clamp
F Switch off the ignition.
F S witch off all electrical consumers (audio
system, lighting, wipers, etc.).
F

S
witch off charger B before connecting the
cables to the battery, so as to avoid any
dangerous sparks.
F

E

condition.
F

R

one, on the (+) terminal.
F

C
onnect charger B cables as follows:
-

t
he (+) red cable to the (+) terminal of
battery A ,
-

t
he (-) black cable to earth point C on the
vehicle. Never try to charge a
frozen battery – risk
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.
F

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.).
F
s
witch off the ignition and wait for four
minutes.
At the battery, detach the (+) terminal only.

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).
