Brake fluid is poisonous
and highly corrosive. In
the event of accidental contact,
wash the parts involved im-
mediately with neutral soap
and water, then rinse thor-
oughly. Call the doctor imme-
diately if the fluid is swal-
lowed.
WARNING

BATTERY
The battery is of the “Limited mainte-
nance” type: under normal conditions
of use the electrolyte does not need top-
ping up with distilled water.
CHECKING THE CHARGE
The battery charge may be checked sat-
isfactorily through the indicatorA-fig.
14and acting according to the colour
the indicator shows.
Refer to the table below.

IMPORTANTThe charge in the bat-
tery should be checked at the start of
winter to limit the risk of electrolyte
freezing. This check should be carried
out more frequently if the car is used
mainly for short trips, or if it is fitted with
accessories that permanently absorb
electricity also with the ignition key re-
moved, especially in the case of after
market accessories.

REPLACING THE BATTERY
If required, replace the battery with a
genuine spare part having the same
specifications.
If a battery with different specifications
is fitted, the service intervals given in
the Service schedule in this section will
no longer be valid.
Refer therefore to the instructions pro-
vided by the battery manufacturer.
Incorrect fitting of elec-
trical and electronic ac-
cessories can seriously
damage the car. If after buying
the car, you want to install elec-
tric accessories which require per-
manent electric supply (alarm,
free-hand phone kit, etc.) contact
Alfa Romeo Authorized Services
whose qualified personnel, in ad-
dition to suggesting the most
suitable devices, will evaluate the
overall electric absorption, check-
ing whether the car’s electric sys-
tem is capable of withstanding
the load required, or whether it
should be integrated with a more
powerful battery.
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 is properly equipped for
disposing of used batteries re-
specting nature and the law.
The liquid in the bat-
tery is poisonous and
corrosive. Avoid contact with
eyes and skin. Do not bring
naked flames or possible
sources of sparks near to the
battery: risk of fire and ex-
plosion.
WARNING
Running the battery
with low fluid level can
damage the battery beyond
repair and could also cause its
explosion.
WARNING
After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in
order to allow the climate con-
trol system control unit to reset
the positions of the electric ac-
tuators that adjust air temper-
ature and distribution.

If the car is left inactive
for long periods at cold,
remove the battery and store
it in a warm place to prevent
freezing.
WARNING
When working on the
battery or near it, al-
ways wear the proper gog-
gles.
WARNING
USEFUL ADVICE FOR
LENGTHENING THE LIFE
OF YOUR BATTERY
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.
IMPORTANTA battery which is kept
at a charge of less than 50% (optical in-
dicator with dark colour without green
area in the middle) for any length of time
will be damaged by sulphation leading to
a reduction in cranking 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”. 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 (factory and after-market) must be less than 0.6 mA x Ah (of the battery) as shown in
the following table:
Battery Maximum admitted stand-by intake
60 Ah 36 mA
70 Ah 42 mA
90 Ah 54 mAIf 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.

Incorrect pressure causes abnormal tyre
wearfig. 15:
Anormal pressure: tread evenly worn.
Blow pressure: tread particularly worn
at the edges.
Chigh pressure: tread particularly worn
in the centre.
Tyres must be replaced when the tread
wears down to 1.6 mm. In any case,
comply with the laws in the country
where the car is being driven.
IMPORTANT NOTES
As far as possible, avoid sharp braking
and screech starts, etc. Be careful not to
hit the kerb, potholes or other obstacles
hard. Driving for long stretches over
bumpy roads can damage the tyres.
Periodically check that the tyres have no
cuts in the side wall, abnormal swelling
or irregular tyre wear. If any of these oc-
cur, have the car seen to at Alfa Romeo
Authorized Services.
Avoid overloading the car when travel-
ling: this may cause serious damage to
the wheels and tyres; if a tyre is punc-
tured, stop immediately and change it
to avoid damage to the tyre, the rim,
suspensions and steering system.
WHEELS AND TYRES
Check the pressure of each tyre, includ-
ing the space-saver spare wheel, every
four weeks and before long journeys:
pressure should be checked with the tyre
rested and cold.
For the correct tyre inflation pressure,
see “Wheels” in “Technical specifica-
tions” section.

Remember that road
holding depends also
on the correct tyre inflating
pressure.
WARNING
If the pressure is too
low the tyre overheats
and this can cause it serious
damage.
WARNING
Never submit alloy
rims to repainting
treatments requiring to use
temperatures exceeding
150°C since the mechanical
properties of the wheels could
be impaired.
WARNING
Do not cross switch the
tyres, moving them
from the right of the car to the
left and vice versa.
WARNINGTyres age even if they are not used
much. Cracks in the tread rubber are a
sign of ageing. In any case, if the tyres
have been on the car for over 6 years,
they should be checked by specialised
personnel, to see if they can still be
used. Also remember to check the space-
saver spare wheel.
In the case of replacement, always fit
new tyres, avoiding those of dubious ori-
gin.
If a tyre is changed, also change the in-
flation valve; to allow even wear be-
tween the front and rear tyres, it is ad-
visable to change them over every 10-
15 thousand kilometres, keeping them
on the same side of the car so as to not
reverse the direction of rotation.

WINDSCREEN/REAR
SCREEN WIPERS
BLADES
Periodically clean the rubber part using
special products TUTELA PROFES-
SIONAL SC 35is recommended.
If the rubber blades are bent or worn
they should be replaced. In any case
they should be changed once a year.
A few simple notions can reduce the pos-
sibility of damage to the blades:
❒ if the temperature fall below zero,
make sure that ice has not frozen the
rubber against glass. If necessary,
thaw using an antifreeze product;
❒ remove any snow from the glass: in
addition to protecting the blades, this
prevents effort on the motor and
overheating;
❒do not operate the windscreen wipers
on dry glass.
RUBBER HOSES
As far as the brake system and fuel rub-
ber hoses are concerned, carefully fol-
low the Service schedule in this section.
Indeed ozone, high temperatures and
prolonged lack of fluid in the system
may cause hardening and cracking of
the hoses, with possible leaks. Careful
control is therefore necessary.
Driving with worn
wiper blades is a seri-
ous hazard, because visibility
is reduced in bad weather.

Then check that the nozzle holes are not
clogged, if necessary use a needle.
Fluid jets shall be directed at about 1/3
height from the window upper edge.
HEADLIGHT WASHERS
Regularly check that the spray jets are
intact and clean.
The headlight washers are automatical-
ly switched on when the windscreen
washer is operated and the dipped
beams are on.
