C.
With the vehicle standing on a flat surface, the
battery fluid level (electrolyte) must be between
the MIN and MAX reference notches shown on
the battery.
If the level is lower than the MIN reference
notch, contact an Authorised Service Centre
of the Manufacturer’s Network to have it
checked.To recharge the battery, see the section “In an
emergency”.
CAUTION
The fluid contained in the
battery is poisonous and corrosive.
Avoid contact with the skin and eyes.
Do not approach the battery with open
flames or possible sources of sparks:
risk of explosion and fire!
Batteries contain substances that are very
harmful for the environment. We advise you
to have the battery replaced at an Authorised
Service Centre of the Manufacturer’s
Network, where all the necessary equipment
is available to dispose of the used parts in compliance with applicable legislation and in an
environment-friendly manner.
WARNING: Incorrect assembly of electrical and
electronic accessories can cause serious damage
to the vehicle.USEFUL HINTS FOR
EXTENDING THE LIFE OF
THE BATTERY
When parking the vehicle, make sure that the
doors, luggage and engine compartment lids
are properly closed. All interior lights should be
off. When the engine is off, do not keep the
connected devices switched on for a long time
(for example the radio, the hazard warning
lights, the fan, etc.).

MAINTENANCE
WARNING: If the battery charge remains
below 50% for a long period of time, it will be
damaged due to sulphating: this will reduce its
performance and starting power and the battery
will be more subject to freezing (this can happen
even at -10°C).We recommend that you have the battery charge
condition checked, preferably at the beginning of
the cold season, to prevent the electrolyte from
freezing.
This check should be performed more frequently
if the vehicle is used mainly for short trips or if it
is equipped with power absorbing devices that
remain permanently on even if when the ignition
key is removed. This applies above all if these
devices have been fitted “after market”.
If the vehicle is not used for long periods of time,
please refer to chapter “If the vehicle is laid up
for long periods”, in this section.WARNING: If additional systems have to be
fitted in the vehicle, there is the risk of creating
dangerous branches on the electric wiring, in
particular if the safety devices are involved.
ELECTRONIC
CONTROL UNITSNo special precautions are required for the
normal use of the vehicle.
In the event of repairs to the electrical system
or in an emergency starting, the following
instructions must be strictly followed:
- Never disconnect the battery from the
electrical system when the engine is
running.
- Disconnect the battery from the electrical
system when recharging it (see page 168
“If the battery is fl at”). WARNING: When the battery is disconnected,
you must first detach the negative pole terminal
(–) and then the positive pole one (+).
WARNING: The battery is secured inside the
vehicle by means of a metal box, therefore, be
extremely careful not to let the battery charger
clips come into contact with it.WARNING: When the battery is reconnected,
you must first attach the positive pole (+),
remembering to cover it with the cap provided,
and then the negative one (–).
- Never perform the emergency starting
procedure using a battery charger: always
use an auxiliary battery.
- Take special care when connecting the
battery to the electrical system, checking
both that polarity is correct and that the
connection is properly working.
- Do not connect or disconnect the terminals
of the ECUs when the ignition key is at
MAR.
- Do not check the electric polarities through
sparking.
- Disconnect the ECUs in the event of
electrical welding on the vehicle body.
Remove them if the temperature is
over 80°C (special interventions on the
bodywork, etc.).

- Store the vehicle in a covered, dry and, if
possible, ventilated area.
- Engage a gear.
- Disconnect the battery (see page 168).
- Check the battery charge condition. This
check should be carried out monthly while
the vehicle is idle. Recharge the battery if
the load-free voltage is below 12.5 V.
- Check that the electric parking brake is not
applied.
- Clean and protect the painted parts applying
protective waxes.
- Clean and protect polished metal parts with
specifi c products available on the market.
- Talc the windscreen wiper blades and raise

If you do not plan on using the vehicle for more
than a week, we advise you to connect the
battery conditioner in order to preserve full
battery efficiency.
Position the device outside the vehicle and be
careful not to “pinch” the connection cable
and/or damage the strips when closing the door.
Arrange the battery conditioner in a well visible
position, away from heat sources and children’s
reach.
Instructions for use: active and passive phase
First connect the battery conditioner to the
socket in the vehicle and then to the mains
socket, thus starting the “Active” phase; the
battery conditioner can stay connected to the
vehicle for months without any contraindications.
Position the device outside the vehicle and be
careful not to “pinch” the connection cable
and/or damage the strips when closing the door.
CAUTION
Arrange the battery conditioner
in a well visible position, away from
heat sources and children’s reach.
Battery conditioning can be interrupted at any
time by disconnecting the power cable from the
mains.

MAINTENANCE
Always first disconnect the power cable from
the mains and then disconnect the battery
conditioner from the vehicle socket. WARNING: The vehicle cannot be started as
long as the battery conditioner is connected to
the vehicle socket (even when it is disconnected
from the mains).When the warning light (1) is on permanently: it
means that there is an electric system fault in the
vehicle or the battery.
When the warning light (2) is on permanently:
it means that the battery conditioner is in the
“Active” phase. During this phase the battery
is recharged to the optimal charge level, from a
lower one.
When the warning light (3) is on permanently:
it means that the battery is fully charged and the
battery conditioner is in the “Passive” phase.
During this phase, the device maintains the
battery at an optimal charge level.
When the warning lights (2 and 3) are on and
flash alternately:
- if the warning lights fl ash a few times a
second, it means that the battery may be
sulphated. - if the warning lights fl ash alternately for
more than 60 minutes, it means that the
battery must be replaced.
- if the warning lights fl ash at intervals of a
few minutes, it means that the battery self-
discharge percentage is high and it might
have to be replaced.
When no warning light is on, the following may
have occurred:
- the battery conditioner cables may be
disconnected;
- the battery may not be properly connected
to the vehicle system;
- the battery may be defective;- the battery voltage may be low or there
may be a lack of power on the mains
socket.
