12 V battery
Procedure for starting the engine using another
battery or charging a discharged 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. If your vehicle has an automatic gearbox,
do not try to start the engine by pushing
the vehicle.
Access to the battery
The battery is located under the bonnet.
For access to the (+) terminal:
F

r
elease the bonnet using the interior lever,
then the exterior lever,
F

r
aise the bonnet and secure it with its stay,
F

l
ift the plastic cover for access to the (+)
terminal.
Starting using another battery
When your vehicle's battery is discharged, the
engine can be started using a slave battery
(external or on 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.
First check that the slave 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 Lift the plastic cover on the (+) terminal, if your vehicle has one.
F

C
onnect the red cable to the positive
terminal (+) of the flat battery A (at the metal
elbow) then to the positive terminal (+) of the
backup battery B or the booster.
F

C
onnect one end of the green or black
cable to the negative terminal (-) of the slave
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 (+) 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 the dealer network 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 Switch 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 (+) 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 . Never try to charge a frozen battery – Risk
of explosion!
If the battery has frozen, have it checked
in the dealer network 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.
Disconnecting the battery
F switch off all electrical consumers (audio
system, wipers, lighting, etc.).
F

S
witch off the ignition and wait for four
minutes.
After having accessed the battery, disconnect
the positive (+) terminal only.
Quick-release terminal clamp
Disconnecting the (+) terminal
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.
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, boot, windows), F

Ra
ise the lever A fully to release the
clamp B .
F

R
emove the clamp B by lifting it off.

Characteristics of the
engines and towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact the dealer
network 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 given on the
manufacturer's plate or label.
For more information, contact the dealer
network or a qualified workshop.
The GTW and towed load values indicated are
valid up to a maximum altitude of 1,000 metres.
The towed load value must be reduced by 10%
for each additional 1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball (which can be dismantled with or
without a tool).
GT W: Gross train weight. High exterior temperatures may result
in a reduction in the per formance of
the vehicle to protect the engine. If the
exterior temperature is above 37°C, limit
the towed load.
Towing with a towing vehicle which is only
slightly laden may negatively affect its
handling.
Towing a trailer increases the braking
distance.
When towing, never exceed the speed
of 62 mph (100 km/h) (obser ve the local
legislation in force).
