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.

Access to the battery
The battery is located under the bonnet.
To access it:
F
o
pen the bonnet using the interior release
lever, then the exterior safety catch,
F

s
ecure the bonnet stay,
F

l
ift the plastic cover on the (+) terminal.The battery (-) terminal is not accessible.
A remote earth point is located on the
front left-hand wheel arch.
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 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

onnect the red cable to the positive
terminal (+) of flat battery A (at the metal
elbow) then to the positive terminal (+) of

cable to the negative terminal (-) of backup
battery B or the booster (or an earth point
on the other vehicle).

cable to earth point C on the broken down
vehicle.

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

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.

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.
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
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
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

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 . 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,
roof (for Cabrio versions)),
