IMPORTANT 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 side door is closed.
IMPORTANT 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 will also be more at risk
of freezing (this can happen as early as
-10°C). Refer to the "Car inactivity"
paragraph in "Starting and driving" if the
car is left parked for a long time.
If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply
(alarm, etc.) or accessories which
influence the electrical supply
requirements, contact a dedicated Alfa
Romeo Dealership, whose qualified
staff will evaluate the overall electrical
consumption.

away from the battery and do
not use objects that might create
sparks: risk of explosion and fire.
128) Using the battery with
insufficient fluid irreparably
damages the battery and may
cause an explosion.
129) If the car will be unused for an
extended period of time in
extremely cold weather

the battery.

27) Incorrect assembly of electrical
and electronic accessories may

etc.) after purchasing the car.
They can suggest the most
suitable devices and above all
advise you whether a higher
capacity battery needs to
be installed.
