USEFUL ADVICE FOR
EXTENDING THE LIFE OF
YOUR BATTERY
To avoid draining your battery and
make it last longer, observe the
following instructions:
when you park the vehicle, ensure
that the doors, tailgate and bonnet
are closed properly, to prevent any
ceiling lights from remaining on inside
the passenger's compartment;
switch off all ceiling lights inside
the vehicle: the vehicle is however
equipped with a system which
switches all internal lights off
automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before carrying out any operation
on the electrical system, disconnect
the negative battery cable through the
suitable terminal:
For versions with Start&Stop
system: the procedure must be
performed by disconnecting the
connector (A) (pressing the button
(B)) from the sensor (C) monitoring
the battery conditions, on the
negative pole (D) of the battery
fig. 379.
324
For versions without Start&Stop
system: disconnect the negative
terminal from the battery terminal.
If the vehicle is equipped with a
battery disconnection function
(disconnector), see the description
of the disconnection procedure
in the "Battery disconnection
function (disconnector)" chapter.
completely tighten the battery
terminals.
WARNING After turning the ignition
key to STOP and having closed
the driver side door, wait at least
one minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to
the battery, make sure that the ignition
key is in the STOP position and the
driver's door is closed.
WARNING If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing its
capacity and efficiency at start-up.The
battery is also more prone to the risk of
freezing (at temperatures as high as -
10°C).Refer to the "Prolonged vehicle
inactivity" chapter in the "Starting and
driving" section if the car is left parked
for a long time.
If, after buying the vehicle, you want
to install electrical accessories which
require permanent electric supply
(alarm, etc.) or accessories that in any
case burden the electrical supply,
contact a Dealership, whose qualified
personnel, in addition to suggesting
the most suitable devices, will evaluate
the overall electrical consumption,
checking whether the vehicle electrical
system is capable of withstanding the
load required, or whether it should
be integrated with a more powerful
battery.
Since some of these devices continue
to consume electricity even when the
motor is off, they gradually run down
the battery.
WARNING If a tachograph is fitted, if
the vehicle is parked for a long period
of 5 days, it is advisable to disconnect
the negative battery terminal to
maintain its charge. If the vehicle is
equipped with a battery disconnection
function (disconnector), see the
description of the disconnection
procedure in the "Battery disconnection
function (disconnector)" chapter in the
"Starting and driving" section.
