ENGINE COOLANT LEVEL
Top up only with the same
fluid contained in the cool-
ing circuit. PARAFLU UP
(red) cannot be mixed with
PARAFLU 11 (blue) or with other
fluids. Should this take place, do
not start the engine and contact Al-
fa Romeo Authorized Service.
The level of the coolant in the header tank
(reservoir) should be checked with the en-
gine cold and the car on a level surface and
it should be between the MINand MAX
marks on the tank. If the level is low, loosen
the header tank cap (A) and slowly pour
a mixture of the fluid specified in the ”Flu-
ids and lubricants ” table in section “Tech-
nical Specifications”, through the filler neck
until nearing the MAXmark; have this op-
eration carried out at Alfa Romeo Authorised
Services.
The antifreeze mixture contained in the
cooling circuit guarantees protection down
to –35°C.fig. 16 - 2.5 V6 24V version

WARNINGContact Alfa Romeo Autho-
rized Services for maintenance and repair
operations. If the level of the oil in the reservoir falls
below the specified level, top up only with
one of the products listed in the table
“Fluids and lubricants” in the “Technical
specifications” chapter as follows:
– Start the engine and allow the oil in the
reservoir to settle.
– When the engine is running turn the
steering wheel lock to lock a few minutes.
– Top up to the MAXlevel notch and
then replace the cover.Oil consumption is very
low, if topping up again is
needed shortly afterwards,
have the system checked for pos-
sible leaks by Alfa Romeo Autho-
rized Services.fig. 19 fig. 18

DIESEL FILTERDRAINING CONDENSATION
WATER
Water in the supply circuit
can seriously damage the
whole injection system and
cause malfunctions to engine oper-
ation. Should the warning lamp
c
turn on, available for the provid-
ed versions/markets, contact as
soon as possible the Alfa Romeo
Authorised Service for drainage op-
erations.
When the car is habitual-
ly driven in dusty areas,
the cleaner should be
changed at shorter intervals than
those given in the Programmed
Maintenance Schedule.Any attempt to clean the
air cleaner may cause se-
rious engine damage.
AIR FILTERThe air cleaner is connected to the tem-
perature and air flow sensors which send the
electrical signals needed for correct opera-
tion of the injection and ignition system to
the control unit.
It must therefore always be in perfect con-
ditions to ensure correct operation of the en-
gine, low consumption and exhaust emis-
sion levels.
If they are not carried out
correctly and with the due
precautions, the operations
involving cleaner replacement de-
scribed herein may compromise the
safety of the car.
This operation should be carried
out by Alfa Romeo Authorized Ser-
vices.

BATTERYThe battery is of the “Limited Mainte-
nance” type and is fitted with an optical in-
dicator (A-fig. 23) for checking the elec-
trolyte level and charge.
Under normal conditions of use the elec-
trolyte does not need topping up with dis-
tilled water. To make sure that it is in effi-
cient conditions, at routine intervals check
the indicator on the battery cover which
should be dark in colour with a green cen-
tral area.
If the indicator is a bright light colour, or
dark without the green central area, contact
Alfa Romeo Authorized Services.Batteries contain sub-
stances that are very
harmful for the environ-
ment. You are advised to have the
battery changed at Alfa Romeo
Authorized Services, which are
properly equipped for disposing of
used batteries respecting nature
and the law.
POLLEN FILTER This has mechanical/electrostatic air fil-
tering actions, provided that the windows
and doors are shut.
Have the pollen filter checked once a year
by Alfa Romeo Authorized Services, prefer-
ably at the onset of summer.
If the car is mainly used in dusty or heav-
ily polluted areas, the filter should be
changed at more frequent intervals than
specified in the Scheduled Maintenance Pro-
gramme.
WARNINGThe failure to replace the fil-
ter can considerably reduce the effectiveness
of the climate control system.

The liquid in the battery is
poisonous and corrosive.
Avoid contact with eyes and skin.
Do not bring naked flames or pos-
sible sources of sparks near to the
battery: risk of fire and explosion.

WARNINGA battery kept at below
50% of its capacity is damaged by sulpha-
tion, the capacity is reduced and starting
is difficult, there is also more possibility of
freezing (this can occur at –10°C). In the
event of a prolonged stop, refer to “Vehi-
cle inactivity”, in the chapter “Getting the
best out of your car”. – Connect the charger cables to the bat-
tery terminals ensuring that the bias is cor-
rect.
– Turn on the charger.
– After charging turn off the charger be-
fore disconnecting it from the battery.
– Reconnect the battery negative termi-
nal (–).
WARNINGIf the car is fitted with an
alarm system, turn off the alarm with the
remote control and deactivate the system
turning the emergency key to “OFF” (see
“Electronic alarm” in “Getting to know your
car” chapter).

tery charging procedure is described only for
informative purposes. This operation should
be carried out by Alfa Romeo Authorized Ser-
vices.
Charging should be slow at a low amp rat-
ing for about 24 hours. Charging for a longer
time may damage the battery.
Charge the battery as follows:
– Disconnect the terminal from the bat-
tery negative (–) pole.
WARNINGWhen reconnecting the neg-
ative battery cable after having disconnect-
ed it, wait for 2 minutes before turning the
key to enable the climate control system
to reset actuator strokes properly.
Never attempt to charge a
frozen battery before
thawing it, the danger of explosion
exists. If it has frozen, always
check that the inside elements are
not broken and that the body is not
cracked, with the risk of acid com-
ing out which is poisonous and cor-
rosive.

USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERYTo avoid quickly draining the battery and
to preserve its operating conditions over the
course of time, carefully follow the instruc-
tions below:
– The terminals must always be tightened.
– As far as possible, avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard lights, parking lights,
etc.).
– When leaving the car parked in a
garage, make sure that the doors, bonnet,
boot and interior lids are properly shut to
prevent lights from staying on.
– Before doing any work on the electric
system, disconnect the battery negative ter-
minal.– If after purchasing the car, you wish to
install electrical accessories which need a
permanent electrical supply (alarm, hands-
free phone, radio-navigator with satellite an-
ti-theft function, etc.) contact Alfa Romeo
Authorized Services whose qualified per-
sonnel, in addition to suggesting the most
suitable devices from Lineaccessori Alfa
Romeo will be able to evaluate the total
electrical absorption, checking whether the
car’s electric system is able to support the
load required or whether a battery with high-
er capacity is necessary. In fact, these de-
vices continue to absorb current with the
ignition key off (car parked, engine off) and
may gradually drain the battery.
REPLACING THE BATTERYIf required, replace the battery with a gen-
uine spare part having the same specifica-
tions. If a battery with different specifica-
tions is fitted, the service intervals given in
the Programmed Maintenance Schedule in
this section will no longer be valid. Refer
to the instructions provided by the battery
manufacturer.
