decreases outside this temperature
range. The battery is equipped with
conditioning systems that ensure that it
operates under optimal temperature
conditions appropriate to its operation.
The components of the hybrid system
in the vehicle (DC/DC, inverter, 48V
auxiliary lithium ion battery, control
module of the electrified dual clutch
automatic transmission) are cooled by an
auxiliary circuit located inside the engine
compartment (for more information
refer to the "Checking levels" paragraph
in the "Servicing and maintenance"
section).
WARNING When replacing the 48 Volt
battery, always contact an Alfa Romeo
Dealership.
WARNING The battery has a limited
service life. Its ability to conserve
the charge decreases with time and
use. The extent to which the battery
capacity decreases will vary depending
on external conditions (e.g. ambient
temperature, etc.) and usage conditions
such as driving style. This is a natural
characteristic of lithium ion batteries
and is not a sign of malfunction. In
addition, although the distance that can
be travelled in electrical mode decreases
as the capacity of the lithium ion battery
decreases, the performance of the car is
not affected.
GENERAL SAFETY INFORMATION
Improper use, or inappropriate work
performed on the components of
the system with incorrectly isolated
equipment, could cause short circuits
and cause accidents due to the
passage of high currents and/or the
high resulting temperatures. For any
repair/maintenance work on the system,
contact exclusively an Alfa Romeo
Dealership.
If the battery system is used in
an inappropriate manner, if it is
damaged/overheats/tampered with or
exposed to adverse environmental
conditions (e.g. very high or very low
temperatures), the battery could
be damaged and release flammable
electrolyte emissions. In these cases,
have the 48 Volt battery replaced:
contact exclusively an Alfa Romeo
Dealership.
The hybrid system does not allow the
48V battery to be recharged using
external devices, so it is recommended
that the vehicle is not left unused for
too long (no more than 3 months) to
prevent the 48V battery from being
discharged beyond the minimum limit, as
it may become unusable as it cannot be
recharged from an external supply.
WARNING
6) The electrolyte inside the battery is
a polluting and flammable material. If
the auxiliary battery is not disposed of
properly, it may cause fire and pollute the
environment.
IMPORTANT
1) If, as a result of a violent impact or
accident, the car has hit the bottom
(underbody), have the battery checked by
qualified technicians.
IMPORTANT
1) Live parts of the vehicle are marked with
safety warning labels. The high-voltage
battery bears a label indicating this danger.
2) Do not dispose of the auxiliary battery
yourself. For more information contact an
Alfa Romeo Dealership.
