Alfa Romeo 147 Manual Do Proprietário

– Do not check for current in the cables by

short-circuiting the ends. 

– If electric welding is to be carried out on

the body, remember to disconnect the elec-
tronic control units, or remove them if the
work involves high temperatures.

You are also reminded that services with

high current absorption switched on by the
user, such as for example: baby bottle warm-
ers, vacuum cleaner, mobile phone, mini
fridge, etc., 

ing process if they are turned on with the
engine off or running at idle speed.

IMPORTANT When installing addition-

al systems on the car, bear in mind that im-
proper branches on connections of the car
wiring are dangerous, particularly if safety
devices are involved.

With normal use of the car, no particular

precautions need to be taken. 

In the event of work on the electric system

or emergency starting, the instructions giv-
en below must absolutely be adhered to: 

– Always switch off the engine before dis-

connecting the battery from the electric sys-
tem.

– If it is necessary to charge the battery,

always disconnect it from the electric sys-
tem.

– When starting in an emergency, only

use an auxiliary battery and not a battery
charger. 

– Check that the bias is correct and that

the connections between the battery and
the electric system are in efficient conditions. 

– Before disconnecting or connecting the

terminals of electronic units, ensure that the
ignition key is not in the 

MAR position.
