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).

5.24
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.

ACCESSORIES
Electrical and electronic accessories
Before installing this type of accessory (particularly for transmitters\
/receivers: frequency bandwidth, power level, po-
sition of the aerial, etc.), make sure it is compatible with your vehic\
le. You can get advice from an authorised dealer.
Connect accessories with a maximum power of 120 Watts only. Fire hazard. When several accessory sockets are
used at the same time, the total power of the connected accessories must\
not exceed 180 watts.
No work may be carried out on the vehicle’s electrical or radio circuits, except by authorised dealers: an incorre\
ctly connecte d
system may result in damage being caused to the electrical equipment and\
/or the components connected to it.
If the vehicle is fitted with any aftermarket electrical equipment, make\
sure that the installation is correctly protected by a fuse.
Establish the rating and position of this fuse.
Using the diagnostic socket
The use of electronic accessories on the diagnostic socket may cause ser\
ious disturbance to the vehicle’s electronic systems.
For your safety we recommend that you use only electronic accessories ap\
proved by the manufacturer, consult an Approved
Dealer. Serious accident risk.
Use of transmitting/receiving devices (telephones, CB equipment etc.).\
Telephones and CB equipment with integrated aerials may cause interferenc\
e to the electronic systems originally fitted to the
vehicle: it is advisable only to use equipment with an external aerial. \
Furthermore, we remind you of the need to conform
to the legislation in force concerning the use of such equipment.
Fitting aftermarket accessories
If you wish to install accessories on the vehicle: please contact an aut\
horised dealer. Also, to ensure the correct operation o f
your vehicle, and to avoid any risk to your safety, we recommend that you use only accessories specifically designed for y\
our
vehicle, which are the only accessories for which the manufacturer will \
provide a warranty.
If you are using an anti-theft device, only attach it to the brake pedal\
.
Obstructions to the driver
On the driver’s side, only use mats suitable for the vehicle, attached with the pre-fi\
tted components, and check the fitting re gu-
larly. Do not lay one mat on top of another. There is a risk of wedging the pedals.
