handling the battery.
•
The battery in this vehicle has a vent
hose that should not be disconnected
and should only be replaced with a
component of the same type (vented).
NOTE:
Remote battery terminals for start are
located in the engine compartment
for jump starting to be used with an
auxiliary battery or a battery from
another vehicle (see "Auxiliary Jump-
Start Procedure" chapter in section "In
an Emergency").
Battery State of Charge
To avoid problems with ignition and/or
the electrical system in general when
you are driving, the battery charge
status is constantly maintained and
guaranteed by the vehicle's recharge
circuit; the main component of which is
the alternator. This circuit is only able to
supply voltage to the battery when the
vehicle is travelling.
The warning light on the instrument
cluster, will indicate any malfunctions
in the recharge circuit or an insufficient
battery charge status (example in figure).
The vehicle contains advanced
electronic systems, such as, for example,
the alarm system and various electronic
control modules, which consume power
even when the ignition device is in STOP
position and the vehicle is not being
used.
Therefore, it is fundamental that the
battery is properly charged to ensure
that the engine starts properly and that
all the electrical/electronic systems in
the vehicle work efficiently.
To Disconnect the Battery
The battery is located on the inner
central side of the boot compartment.
To access the battery it is necessary to
lift the ground coverage of the boot
compartment (see chapter "Tool Kit" in
section "In an Emergency") and remove
the battery cover.
Maintenance and Care
CAUTION!
• Before disconnecting the battery,
open the boot lid. The boot lid must
remain open until the charged battery
is reconnected.
•
Never disconnect the battery from the
electrical system when the engine is
running.
• To temporarily disconnect the vehicle
electrical system from the battery,
simply remove the cable end with
quick coupling from the negative post (
–) of the battery.
• If the battery needs to be removed
from its compartment, you must first
detach the terminal clamp to the
negative post (–) and then the other
terminal clamp to the positive post (+),
after removing the protective cover.
Battery posts are marked positive (+)
