BATTERY (1/2)
1
Battery 1 does not require any mainte-
nance. You should not open it or add
any fluid.
Handle the battery with care
as it contains sulphuric acid
which must not come into
contact with the eyes or
skin. If it does, wash the affected
area with plenty of cold water. If
necessary, consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
Please note when work-
ing close to the engine that
it may be hot. In addition,
the engine cooling fan may
start at any moment. The

warning light in the engine compart-
ment reminds you of this.
Risk of injury.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).
Depending on the vehicle, a system
continuously checks the battery charge
status. If this decreases, the message
“Battery low start engine” is displayed
on the instrument panel. In this case,
start the engine. The message will go
off.
The charge status of your battery can
decrease especially if you use your ve-
hicle:
– for short journeys;
– for driving in town;
– when the temperature drops;
– after extended use of energy-con- suming devices (radio, etc.) with the
engine switched off.

BATTERY: troubleshooting (1/2)
To avoid all risk of sparks:
– Ensure that any consumers (cour-tesy lights, etc.) are switched off
before disconnecting or reconnect-
ing the battery;
– when charging, stop the charger before connecting or disconnecting
the battery;
– to avoid creating a short circuit be- tween the terminals, do not place
metal objects on the battery;
– always wait at least one minute after the engine has been switched off
before disconnecting a battery;
– make sure that you reconnect the battery terminals after refitting.
Connecting a battery charger
The battery charger must be com-
patible with a battery with nominal
voltage of 12 volts.
Do not disconnect the battery when the
engine is running. Follow the instruc-
tions given by the manufacturer of
the battery charger you are using.
Special procedures may be
required to charge some
batteries. Contact your au-
thorised dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well venti-
lated area.
Risk of serious injury.
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water. If necessary,
consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion. There is a risk of
explosion.
The engine may be hot when car-
rying out operations in close prox-
imity. In addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Before performing any
action in the engine com-
partment, the ignition must
be switched off (please see
the information on “Starting, stop-
ping the engine” in Section 2).
Please note when work-
ing close to the engine that
it may be hot. The engine
cooling fan may also start
at any moment. The
 warning
light in the engine compartment re-
minds you of this.
Risk of injury.

5.31
Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al-
ready have jump leads, ensure that
they are in perfect condition.
The two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Ensure that there is no risk of contact
between the two vehicles (risk of short
circuiting when the positive terminals
are connected) and that the discharged
battery is properly connected. Switch
off your vehicle ignition.
Start the engine of the vehicle supply-
ing the current and run it at a moderate
speed.

Lift the red cover on box 1 located
behind the battery.
Connect the positive cable A to sup-
port 3 (+) located under the box
cover 1, then to terminal 5 (+) of the
battery supplying the current.
Connect the negative cable B to termi-
nal 4 ( – ) of the battery supplying the
current then to the metal cable 2 ( – )
of the discharged battery.

Check that there is no con-
tact between leads A and B
and that the positive lead A
is not touching any metal
parts on the vehicle supplying the
current.
Risk of injury and/or damage to the
vehicle.
Start the engine, and as soon as it starts
running, disconnect cables A and B in
reverse order (2 - 4 - 5 - 3).
