12 V battery
Procedure for starting the engine using another
battery or charging a discharged battery.
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 is located under the bonnet.
For access to the (+) terminal:
F

r
elease the bonnet by activating the internal
control, then the external control,
F

l
ift the bonnet, then hold it in place with its
st ay.
(+) Positive terminal.
It has a quick-release clamp.
(-) Negative terminal.
The battery (-) terminal is not accessible, use
the engine mounting.
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a back-up 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 back-up
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.
F
L
ift the plastic cover on the (+) terminal, if
your vehicle has one.
In the event of a breakdown

203
F Connect the red cable to the positive terminal (+) of the flat battery A (at the metal
elbow) then to the positive terminal (+) of the
back-up battery B or the booster.
F

C
onnect one end of the green or black
cable to the negative terminal (-) of the
back-up 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 the earth point C on the broken
down vehicle.
F

S
tart 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 turn.
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 positive
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.
In some circumstances it may be necessary to
charge the battery:
-

i
f you use your vehicle mostly 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.
If you plan to charge your vehicle's battery
yourself, use only a charger compatible
with lead-acid batteries of 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.).
F
S
witch off the charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
F

E
nsure that the charger cables are in good
condition.
F

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

C
onnect the charger B cables as follows:
-

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

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

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

In the event of a breakdown

204
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. 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.
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. Before disconnecting the battery:
F

c
lose all openings (doors, tailgate, windows,
sunroof),
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, it is only necessary to
disconnect the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal
F

Ra
ise the lever A fully to release the
clamp


B.
F

R
emove the clamp B by lifting it off. Reconnecting the (+) terminal
F

Ra
ise the lever A fully.
F R efit the open clamp B on the (+)
terminal.
F P ush the clamp B fully down.
F

L
ower the lever A to lock the clamp B.
Do 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
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting
the engine, in order to enable the electronic
systems to initialise.

Characteristics of engines
and towed loads
Engines
The engine specifications (capacity, max.
power, max. speed, energy, CO
2 emissions,
etc.) associated with your vehicle are given in
the registration document, as well as in sales
brochures.
These characteristics correspond to the
values type-approved on a test bed, under
conditions defined in European legislation
(Directive
1

999/99/EC).
For more information, contact a CITROËN
dealer or a qualified workshop.
Weights and towed loads
The maximum weights and towed loads for
your vehicle are given in the registration
document, as well as in sales brochures.
These values are also shown on the
manufacturer's nameplate or label.
For more information, contact a CITROËN
dealer or a qualified workshop. The GTW values and the towable loads
listed are valid for a maximum altitude of
1,000
metres. The towable load must be
reduced by steps of 10% for each additional
1,000

metres.
The maximum authorised nose weight
corresponds to the weight permitted on the
towbar.
GT W: Gross train weight.
High exterior temperatures may result
in a reduction in the per formance of the
vehicle to protect the engine. When the
exterior temperature is higher than 37°C,
limit the towed weight.
Towing using a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
When using a vehicle to tow, never exceed
a speed of 60 mph (100 km/h) (obser ve
the local legislation in force). If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2
minutes after the vehicle
comes to a stop, to facilitate its cooling.
