To avoid damaging the
vehicle’s electrical sys-
tem follow the manu-
facturer’s system instructions ac-
companying the jump leads. The
jump leads must be of a suffi-
cient cross-section and long
enough to ensure that the two
vehicles do not touch.
Never use a quick bat-
tery charger to start
the engine in an emer-
gency as this could damage the
electronic systems of your vehi-
cle, particularly the control units
which manage the starting and
supply functions.
The battery terminal
connecting and discon-
necting operations gen-
erate current that may cause
problems to the car’s electronic
systems. Therefore, this opera-
tion should be carried out by
skilled personnel.
At the end of the operation refit the bat-
tery cover.
IMPORTANT If the battery was com-
pletely drained, it may be necessary to
carry out the Alfa Romeo I.C.S. “self-
teaching” operation as follows:
– Let the engine idle to allow the bat-
tery to recharge and make sure it will
start next time.
– Switch the engine off.
– Turn the ignition key to MARand
leave it in this position for 30 seconds to
1 minute, then turn it to STOPfor about
5 to 10 seconds, after which the engine
can be started.
This starting procedure
must be carried out by
qualified personnel as incorrect op-
erations may provoke electrical
discharge of great intensity. The
liquid contained in the battery is
toxic and corrosive. Avoid contact
with skin and eyes.
Keep naked flame, and lighted cig-
arettes away from the battery. Do
not cause sparks.
WARNING

a soft cloth, insert the screwdriver on the
upper part of the cap and press gently to
prise the catch from its housing.
– Firmly screw the ring (B-fig. 99) in
