Starting using another
battery
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 all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to moving parts of the engine (fan,
belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
After every reconnection of the battery, switch
on the ignition and wait 1

minute before
starting to allow the electronic systems to be
initialised. If slight difficulties are experienced
after this, please contact a

CITROËN dealer or
a


qualified workshop. The positive battery terminal A is accessible
via an access cover located at the side of the
fusebox.
Make connections only to the points indicated
and illustrated above. If you fail to follow this
instruction there is the danger of a
short-circuit!
F Connect the red cable to the battery terminal A then to the positive (+) terminal of
the backup battery B .

C. Earth on your vehicle
It is advisable to disconnect the negative
(-) terminal of the battery if the vehicle is
not to be used for a

period of more than
one month.
The description of the battery charging
procedure is given as an indication only.
If the battery has been disconnected for some
time, it may be necessary to reinitialise the
following functions:
-

t

he display parameters (date, time,
language, units of distance and
temperature),
-
r

adio stations,
-

c

entral locking.
Some settings are cleared and must be
reprogrammed; consult a


CITROËN dealer.
If your vehicle is fitted with a

tachograph or an
alarm, disconnection of the negative (-) terminal
of the battery (located under the floor on the
left-hand side, in the cab) is recommended
if the vehicle is not to be used for a

period of
more than 5

days.

To w i n g
General recommendations
Obser ve the legislation in force in your
c o u nt r y.
Ensure that the weight of the towing
vehicle is higher than that of the towed
vehicle.
The driver must remain at the wheel of
the towed vehicle and must have a valid
driving licence.
When towing a
vehicle with all four wheels
on the ground, always use an approved
towbar; rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine
off, there is no longer braking and steering
assistance.
In the following cases, you must always
call on a
professional recovery ser vice:
-

v
ehicle broken down on a motor way or
main road,
-
f

our-wheel drive vehicle,
-

w
hen it is not possible to put the
gearbox into neutral, unlock the
steering, or release the parking brake,
-

t
owing with only two wheels on the
ground,
-

w
here there is no approved towbar
available.
The charging operation must be carried
out in a

ventilated area away from naked
flames or any possible sources of sparks
to eliminate the risk of explosion and fire.
Do not try to charge a

frozen battery: it
must first be thawed out to avoid the risk
of explosion. If the battery has frozen,
before charging it have it checked by
a

specialist who will verify that the internal
components have not been damaged and
that the case is not cracked, which could
mean that there is a

risk of a

leak of toxic
and corrosive acid.
Proceed with a

slow charge at low current
for a

maximum of about 24

hours to avoid
damaging the battery.
Charging the battery using
a battery charger
F Go to the battery located in the front left
f l o o r.
F

D
isconnect the battery.
F

F
ollow the instructions for use provided by
the manufacturer of the charger.
F

R
econnect starting with the negative (-)
terminal.
F

C
heck the condition of the terminals and
clamps. If they are covered with sulphate
(whitish or greenish deposits), disconnect
them and clean them all.
After refitting of the battery by a
CITROËN
dealer or a
qualified workshop, the Stop
& Start system will only be active after
a


continuous 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


h o u r s).
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 specification;
the involvement of a
CITROËN dealer or
a
qualified workshop is essential when
replacing or disconnecting the battery.
