CAR MAINTENANCE

Do not travel with the
windscreen washer reser-
voir empty: the action of
the windscreen washer is funda-
mental for improving vision.
To avoid damaging the
pump motor, do not use the
windscreen/rearscreen
washers when the reservoir is
empty.
Some commercial addi-
tives for windscreen wash-
ers are inflammable. The
engine compartment contains hot
components which may set it on
fire.
IMPORTANTBrake and hydraulic clutch
fluid is hygroscopic (i.e. it absorbs moisture).
For this reason, if the car is mainly used in
areas with a high degree of atmospheric hu-
midity, the fluid should be replaced at more
frequent intervals than specified in the
Scheduled Maintenance Programme.
WINDSCREEN/REARSCREEN
HEADLIGHT WASHER FLUID
(fig. 13)
Open the cap (A) and check the level in
the reservoir.
If necessary top up using a mixture of wa-
ter and TUTELA PROFESSIONAL SC
35fluid as follows:
– 30% of TUTELA PROFESSIONAL
SC 35and 70% water in summer; Brake and clutch fluid is
poisonous and highly cor-
rosive. In the event of ac-
cidental contact, wash the parts
concerned immediately with neu-
tral soap and water, then rinse
thoroughly. See a doctor at once if
the fluid is swallowed.
Theπsymbol on the con-
tainer indicates synthetic
brake fluid, distinguishing
it from the mineral kind. Using min-
eral fluids irreversibly damages the
special braking system rubber
seals.

– 50% of TUTELA PROFESSIONAL
SC 35and 50% water in winter;
– in the case of temperatures below
–20°C use TUTELA PROFESSIONAL
SC 35fluid neat. Make sure that the high-
ly corrosive brake fluid
does not drip onto the
paintwork. If it does, wash it off
immediately with water.

CAR MAINTENANCE

Proceed as follows with doors closed:
1.open completely the driver’s window
keeping the button pressedfor at
least 3 seconds after full opening;
2.close completely the driver’s window
keeping the button pressedfor at
least 3 seconds after full closing;
3.proceed as described in points 1 and
2 also for the passenger’s side;
4.check for proper initialisation by oper-
ating the windows in automatic.
USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERY
To avoid rapidly draining the battery and
ensure that it continues to work correctly,
the following should be noted:
– The terminals must always be firmly
tightened.
– As far as possible, avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard lights, parking lights,
etc.). IMPORTANTIf the battery is kept with
a charge of below 50% it is damaged by sul-
phation, its starting capability is reduced and
it is also more subject to the possibility of
freezing (this may occur already at -10 °C).
In the event of a prolonged inactivity, refer
to the paragraph “car inactivity”, in the
chapter “Correct use of the car”.
CHANGING
THE BATTERY
When changing the battery it should be re-
placed with another original one with the
same characteristics. If it is replaced by a
battery with different characteristics, the
maintenance intervals given in the Sched-
uled Maintenance Programme in this chap-
ter are no longer valid and for maintenance
it will be necessary to follow the battery
Manufacturer’s instructions.
IMPORTANTLacking power to control
units (e.g. battery change/disconnection
and replacement of power window control
unit protection fuses), window automatism
must be reset.– 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 carrying out any work on the
electric system, disconnect the negative ca-
ble from the battery.
– If after buying the car, you wish to in-
stall electric accessories which require a per-
manent electric supply (alarm, voice feature,
radionavigator with satellite antitheft func-
tion etc.) or accessories that burden the elec-
tric system, contact Alfa Romeo Authorised
Services whose qualified personnel, in ad-
dition to suggesting the most suitable de-
vices belonging to Lineaccessori Alfa Romeo,
will evaluate the overall electric absorption,
checking whether the car’s electric system
is capable of withstanding the load required,
or whether it should be integrated with a
more powerful battery. In fact, as some of
these devices continue absorbing energy
even when the ignition key is off (car sta-
tionary, engine off), they gradually drain the
battery.

HEADLIGHT WASHERS
(fig. 19)
Regularly check that the spray jets are in-
tact and clean.
If it is necessary to direct the jet, contact
an Alfa Romeo Authorized Service.
BODYWORK
PROTECTION FROM
ATMOSPHERIC AGENTS
The main causes of corrosion are:
– atmospheric pollution
– salty air and humidity (coastal areas, or
hot humid climates)
– seasonal environment conditions.
Not to be underestimated is also the abra-
sive action of wind-borne atmospheric dust
and sand and mud and gravel raised by oth-
er cars.
On your car, Alfa Romeo has implement-
ed the best manufacturing technologies to
effectively protect the bodywork against cor-
rosion.
fig. 19
A0A0704b
These include:
– Painting products and systems which
give the car particular resistance to corrosion
and abrasion.
– Use of galvanised (or pretreated) steel
sheets, with high resistance to corrosion.
– Spraying of the underbody, engine com-
partment, wheel arches and other parts with
highly protective wax products.
– Spraying of plastic parts, with a protec-
tive function, in the more exposed points:
underdoor, inner wheel arch linings, etc.
– Use of “open” boxed sections to pre-
vent condensation and pockets of moisture
from triggering rust inside.
CAR EXTERIOR AND
UNDERBODY WARRANTY
Your car is covered by warranty against
perforation due to rust of any original ele-
ment of the structure or body. For the gen-
eral terms of this warranty, refer to Alfa
Romeo Warranty booklet.

CAR MAINTENANCE

Engine compartment
At the end of the winter the engine com-
partment should be carefully washed, with-
out directing the jet against electronic con-
trol units. Contact a specialised workshop to
have this done.
Detergents cause water
pollution. Therefore the en-
gine compartment should
be washed in areas equipped for
collecting and purifying the liquid
used in the washing process.
IMPORTANTThe car should be washed
with the engine cold and the ignition key at
STOP. After washing make sure that the
various protections (e.g. rubber caps and
various covers) have not been damaged or
removed. Windows
Use specific products to clean the windows.
Use clean cloths to avoid scratching or al-
tering the transparency of the glass.
IMPORTANTThe inside of the
rearscreen should be wiped gently with a
cloth in the direction of the filaments to
avoid damaging the heating device.
Front headlights
IMPORTANTDo not use aromatic sub-
stances (e.g. petroleum) or ketones (e.g.
acetone) to clean the front headlight plas-
tic transparents.
Never use inflammable
products like fuel oil ether
or rectified petrol for clean-
ing inside the car. The electrostat-
ic charges generated when rubbing
to clean may cause fire.
INTERIOR FITTINGS
Periodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause
oxidisation on the sheet metal.
CLEANING SEATS AND FABRIC
AND VELVET PARTS
– Use a soft brush or a vacuum cleaner to
remove dust. Velvet is cleaned better if the
brush is moistened.
– Rub the seat with a sponge moistened
with a solution of water and neutral deter-
gent.
