(+) Positive terminal.
It has a quick-release clamp.
(-) Negative terminal.
As the battery's negative terminal is not
accessible, a remote earth point is placed near
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 using a
battery booster.
For access to the (+) terminal:
F

u
nlock the bonnet by activating the internal
release lever, then the external safety catch.
F
r
aise the bonnet.
Never 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 all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to the moving parts of the engine
(fan, belt, etc.).
Do not disconnect the (+) terminal while
the engine is running. 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 to an earth point on the
assisting vehicle).
F

30 minutes, by driving or with the vehicle
stationary, so that the battery reaches an
adequate state of charge.
If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.

217
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.
In some circumstances, it may be necessary to
charge the battery:
-

u
sing the vehicle mainly 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.
To charge the 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

S
witch off the ignition.
F
S
witch off all electrical consumers (audio
system, lighting, wipers, etc.). 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 verify that the internal
components have not been damaged
and that the case has not cracked, which
would mean a
risk of toxic and corrosive
acid leaking.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Disconnecting the battery
F Switch off charger B before connecting the cables to the battery, so as to avoid any
dangerous sparks.
F

E

condition.
F

I
f the vehicle has one, lift the plastic cover
on the (+) terminal.
F

C
onnect the cables of charger B as follows:
-

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

t
he negative (-) black cable to earth point
C on the vehicle.
F

A
t the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A . 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.
Before disconnecting the battery:
F

c
lose all openings (doors, tailgate, windows,

-

t
he electric windows,
-

t
he date and time,
-

t
he preset radio stations.
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).
