Alfa Romeo 159 オーナーマニュアル

To avoid draining your battery and
lengthen its life, observe the following
indications:
❒ when you park the car, ensure the

doors, tailgate and bonnet are closed
properly;

❒ the ceiling lights must be off. The car

is however provided with an auto-
matic system for switching off inter-
nal lights;

❒ do not keep accessories (e.g.: sound

system, hazard lights, etc.) switched
on for a long time when the engine
is not running;

❒ before performing any operation on

the electrical system, disconnect the
battery negative terminal cable;

❒ battery terminals shall always be per-

fectly tightened.

IMPORTANT A battery which is kept
at a charge of less than 50% for any
length of time will be damaged by sul-
phation leading to a reduction in crank-
ing power.
Moreover, this might lead to a higher
risk of the battery electrolyte freezing
(this may even occur at –10°C). If the
car is inactive for a long period of time,
refer to “Car inactivity”, in section “Cor-
rect use of the car”. 

If after buying the car, you want to in-
stall electric accessories which require
permanent electric supply (alarm, etc.)
contact Alfa Romeo Authorized Services
whose qualified personnel, in addition
to suggesting the most suitable devices
available at Lineaccessori Alfa Romeo,
will evaluate the overall electric ab-
sorption, checking whether the car’s
electric system is capable of withstand-
ing the load required, or whether it
should be integrated with a more pow-
erful battery.

In fact, since these devices continue ab-
sorbing energy even when the ignition
key is off, they gradually run down the
battery.
The total intake of these systems (fac-
tory and after-market) must be less than
0.6 mA x Ah (of the battery) as shown
in the following table:

60 Ah

70 Ah

90 Ah

36 mA

42 mA

54 mA
