ENGINE OIL (fig. 5-6-7-8)
The engine oil should be checked with the
car on a level surface a few minutes (about
5) after the engine has been switched off.
Remove the dipstick (A), clean it, put it
back in completely, remove it and check that
the level is within the MINandMAX
marks on the dipstick. The interval between
theMINandMAXmarks correspond to
about one litre of oil.When the engine is hot,
take care when working
inside the engine compart-
ment to avoid burns. Remember
that when the engine is hot, the
fan may cut in: danger of injury.
Never add oil with char-
acteristics (classification,
viscosity) which are differ-
ent from those of the oil already in
the circuit.

If the oil level is near or even below the
MINmark, add oil through the filter neck
(B), until reaching the MAXmark.
IMPORTANTIf a routine check reveals
that the level is above the MAXmark, con-
tact Alfa Romeo Authorised Services to have
the correct level restored.
IMPORTANTAfter topping up the oil,
before checking the level again, run the en-
gine a few seconds and wait for a few min-
utes after stopping it.

Used engine oil and filter
contain harmful substances
for the environment. Con-
tact Alfa Romeo Authorised Ser-
vices to have the oil and the filter
changed, as they are equipped to
dispose of the waste oil and filters
respecting nature and the law.
SELESPEED TRANSMISSION
OIL
(fig. 9)
The Selespeed transmission oil should be
checked with the car on a level surface and
with the engine stopped and cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and re-
move the cap (A) checking that the level
corresponds with the MAXmark on the dip-
stick integrated with the cap;
– if the oil is below the MAXmark, top
up to reach the correct level;Do not add oil with spec-
ifications other than that
already in the gearbox.

A0A0197b
Used gearbox oil contains
dangerous substances for
the environment. For chang-
ing the oil we advise contacting Al-
fa Romeo Authorised Services who
are equipped for disposing of used
oil respecting nature and the law.
Be very careful working
inside the engine compart-
ment if the engine is hot:
danger of burns. Remember that
the fan may cut in if the engine is
very hot: danger of injury.
Engine oil consumption
Max engine oil consumption is usually 400
grams every 1000 km.
During the initial period of use the engine
settles, therefore engine oil consumption
may be considered stabilised only after the
first 5000 ÷ 6000 km.
IMPORTANTEngine oil consumption de-
pends on the way of driving and the condi-
tions of use of the car.– after refitting the cap, insert the
breather tube firmly on the housing on the
cap and turn the ignition key to STOP.

CAR MAINTENANCE

The cooling system is
pressurised. If necessary,
replace the cap only with
another genuine one, otherwise
system efficiency could be compro-
mised. Do not remove the reservoir
cap when the engine is hot: you
risk scalding yourself.
The cooling system uses
PARAFLU UP antifreeze.
Do not add fluid having dif-
ferent specifications from that al-
ready existing. PARAFLU UP can-
not be mixed with other types of
fluids. Should other fluids be
added, do not start the engine and
contact Alfa Romeo Authorized
Services as soon as possible.ENGINE COOLANT FLUID
(fig. 10)
Do not remove the cap
when the engine is hot:
danger of burns.
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 MINandMAX
marks on the tank.
fig. 10
A0A0240b
If the level is low, loosen the header tank
cap (A) and slowly pour a mixture of 50%
distilled water and 50% PARAFLU UP FL
Seleniathrough the filler neck until near-
ing the MAXmark.
The antifreeze mixture of 50% PARAFLU
UPand 50% distilled water guarantees pro-
tection down to –35 °C.

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-
rised Services.Do not allow the power
steering fluid to touch hot
parts of the engine: it is in-
flammable.

BRAKE AND HYDRAULIC
CLUTCH FLUID
(fig. 12)
Check that the fluid level in the reservoir
is at maximum. Top up with the brake fluid
specified in the table “Fluids and lubricants”
(see section “Technical specifications").
NOTEClean accurately the tank cap A
and the surrounding surface. When opening
the cap take the utmost care to prevent im-
purities entering the tank. When topping up,
always use a funnel with built-in filter with
mesh equal to or lower than 0.12 mm.
IMPORTANTFor this operation it is
however recommended to contact Alfa
Romeo Authorised Services.
POWER STEERING FLUID
(fig. 11)
Check that the level of the oil in the reser-
voir is at maximum.
This operation should be carried out with
the car on a level surface and the engine
switched off and cold.
Check that the level reaches the MAX
mark on the reservoir or coincides with the
upper notch (maximum level) on the dip-
stick (A) integral with the reservoir cap.If the oil level in the reservoir is below the
specified one, top up only with one of the
products listed in the “Fluids and lubricants”
table in the “Technical specifications” chap-
ter proceeding as follows:
– Start the engine and wait for the oil lev-
el in the reservoir to stabilise.
– With the engine running, turn the steer-
ing wheel lock to lock a few times.
– Top up to the MAXlevel notch, then
refit the cap.

CAR MAINTENANCE
228
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.

DIESEL FUEL FILTER
(diesel versions)
DRAINING CONDENSATION
WATER
The presence of water in
the supply circuit may
cause serious damage to
the entire injection system and
cause irregular running of the en-
gine. If the warning message +
symbol are shown on the recon-
figurable multifunction display con-
tact Alfa Romeo Authorized Ser-
vices as soon as possible to have
the system relieved. If warning in-
dications turn on after refuelling,
water has probably been poured
into the tank: turn the engine off
immediately and contact Alfa
Romeo Authorized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
to the control unit the electric signals need-
ed for correct operation of the injection and
ignition system.
It must therefore always be in perfect con-
ditions, to ensure correct operation of the
engine, low consumption and exhaust emis-
sion levels.
If the operations concern-
ing cleaner replacement de-
scribed below are not car-
ried out correctly and with the due
precautions, they may compromise
the travelling safety of the car. You
are recommended to have this op-
eration carried out by Alfa Romeo
Authorised Services.
If the car is habitually
used in dusty areas, the
cleaner should be replaced
at shorter intervals than those
specified in the Programmed Main-
tenance Schedule.
Any attempt to clean the
cleaner may damage it,
leading to serious engine
damage.

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.

CAR MAINTENANCE

Incorrect pressure causes abnormal tyre
wear:
(A): normal pressure: tread evenly worn.
(B): low pressure: tread particularly worn
at the edges.
(C): high pressure: tread particularly worn
in the centre.
Tyres should be changed when the tread
thickness is reduced to 1.6 mm.
In any case follow local regulations.
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., quicken the battery drain-
ing processif they are turned on with the
engine off or running at idle speed.
IMPORTANTWhen 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.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel, in-
cluding the spare, every two weeks and be-
fore a long journey. The pressure should be
checked with the tyre rested and cold.
It is normal for the pressure to increase
when the car is in use; for the correct tyre
inflation pressure, see “Wheels” in the
“Technical Specifications” chapter.

(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.

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.
