ADDITIONAL
OPERATIONS
Every 1000 kmor before long jour-
neys, check and if necessary top up:
– engine coolant fluid level
– brake/hydraulic clutch control fluid
level
– power steering fluid level
– windscreen and headlamp washer
fluid level
– tyre pressure and conditions.
Every 3000 kmcheck and if necessary
top up the engine oil level.
The use of FL Seleniaproducts is rec-
ommended which have been designed
and made expressly for Alfa Romeo cars
(see “Refuelling” in the “Technical
Specifications” chapter).
ANNUAL INSPECTION
PROGRAMME
For cars with an annual mileage
of below 20,000 km (for exam-
ple about 10,000 km) the follow-
ing yearly inspection programme
is advised:
– Check tyre conditions/wear and if
necessary adjust the pressure (including
spare wheel)
– Check operation of lighting system
(headlights, direction indicators, hazard
warning lights, boot, passenger compart-
ment, glovebox lights, warning lights,
etc.)
– Check operation of windscreen wiper
system, spray jet adjustment
– Check position/wear of windscreen
– Check front disk brake pad conditions
and wear– Sight check for conditions of: engine,
gearbox, transmission, pipes (exhaust -
fuel supply - brakes), rubber parts (boots
- sleeves - bushes etc..), brake and fuel
supply system hoses
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication
– Check battery charge
– Sight check for conditions of various
drive belts
– Check and if necessary top up fluid
levels (engine coolant, brakes, wind-
screen washer, battery etc. )
– Change engine oil and engine oil filter
– Change pollen filter.

Oil consumption is very
low; if topping up again is
needed shortly after-
wards, have the system checked
for possible leaks by Alfa Romeo
Authorised Services.

When loosening the
reservoir cap do not
allow the fluid to come
into contact with painted parts. If
it does, wash it off immediately
with water. Do not allow the power
steering fluid to touch hot
parts of the engine: it is
inflammable.

BRAKE AND HYDRAULIC
CLUTCH FLUID
(fig. 10)
Slacken the cap (A) and check that the
fluid contained in the reservoir reaches the
maximum mark.
POWER STEERING FLUID
(fig. 9)
Check that the level of the oil in the
reservoir is at maximum.
This operation should be carried out with
the vehicle 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 “Fluid and lubri-
cant Specification” table in the “Technical
Specifications” chapter proceeding as fol-
lows:– Start the engine and wait for the oil
level in the reservoir to stabilise.
– With the engine running, turn the
steering wheel lock to lock a few times.
– Top up to the MAXlevel notch, then
refit the cap.

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
warmers, vacuum cleaner, mobile phone,
mini fridge, etc., quicken the battery
draining processif they are turned on
with the engine off or running at idle
speed.
IMPORTANT When installing addi-
tional systems on the vehicle, bear in
mind that improper branches on connec-
tions of the vehicle wiring are dangerous,
particularly if safety devices are involved.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel,
including the spare, every two weeks and
before 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.

The maximum absorption of all the
accessories (standard and fitted after-
wards) should be 0,6 mA x Ah (of the bat-
tery), as shown in the following table:

Alloy rim painting
involving temperatures
exceeding 150 °C should
be avoided since wheel mechani-
cal characteristics could be
impaired.Do not cross switch the
tyres, moving them from
the right of the car to the
left and vice versa.Excessive low pressure
causes overheating of the
tyre with the possibility
of serious damage to it.Remember that vehicle
road holding also depends
on correct tyre inflation
pressure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully
follow the Scheduled Maintenance
Programme. Indeed, ozone, high temper-
atures and the prolonged lack of fluid in
the system may cause hardening and
cracking of the hoses, with possible leaks.
Careful control is therefore necessary. IMPORTANTS
– Where possible, avoid sudden brak-
ing, tyre squealing starts, violent bumps
against kerbs, potholes or obstacles of var-
ious kinds. Prolonged driving on rough
roads may damage the tyres;
– Routinely check the tyres for cuts on
the sides, swellings or uneven tread wear.
If necessary contact Alfa Romeo
Authorised Services;
– Avoid overloading the vehicle when
travelling: this may cause serious damage
to the wheels and tyres;
– If a tyre is punctured, stop immedi-
ately and change it to avoid damage to
the tyre itself, the rim, suspensions and
steering system;
– Tyres age even if they are not used
much. Cracks in the tread rubber are a
sign of aging. In any case, if the tyres
have been on the vehicle for over 6 years,
they should be checked by specialised per-
sonnel, to see if they can still be used.
Also remember to check the compact
spare wheel;
– In case of replacement, always fit new
tyres, avoiding those of dubious origin;

HEADLIGHT WASHERS
(fig.17)
Regularly check that the spray jets are
intact and clean.
If it is necessary to direct the jet, contact
an Alfa Romeo Authorised 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
abrasive action of wind-borne atmospheric
dust and sand and mud and gravel raised
by other vehicles.
On your car Alfa Romeo has implement-
ed the best manufacturing technologies to
effectively protect the bodywork against
corrosion.
fig. 17
A0A0704b
These include:
– Painting products and systems which
give the vehicle particular resistance to
corrosion and abrasion.
– Use of galvanised (or pretreated)
steel sheets, with high resistance to corro-
sion.
– Spraying of the underbody, engine
compartment, wheel arches and other
parts with highly protective wax products.
– Spraying of plastic parts, with a pro-
tective function, in the more exposed
points: underdoor, inner wheel arch lin-
ings, etc.
– Use of “open” boxed sections to pre-
vent condensation and pockets of mois-
ture from triggering rust inside.
VEHICLE EXTERIOR AND
UNDERBODY WARRANTY
Alfa GTis guaranteed against perfo-
ration due to rust of any original element
of the structure or body. For the general
terms of this warranty, refer to the
Warrantly Booklet.

Do not keep aerosol cans
in the car. They might
explode. Aerosol cans
must never be exposed to a tem-
perature above 50°C. The tem-
perature inside the car exposed
to the sun may go well beyond
that figure.
CLEANING LEATHER SEATS
– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid and grease stains with
a dry absorbent cloth without rubbing.
Then wipe with a soft cloth or chamois
leather with water and neutral soap. If the
stain persists, use specific products, care-
fully following the instructions for use.
IMPORTANTNever use alcohol. Make
sure that cleaning products do not contain
alcohol and alcohol derivatives even at
low strength.
STEERING WHEEL/GEAR LEVER
KNOB WITH GENUINE
LEATHER COVERING
These components shall only be cleaned
with water and neutral soap. Never use spir-
it or alcohol-based products.
Before using special products for cleaning
interiors, read carefully label instructions and
indications to make sure they are free from
spirit and/or alcohol-based substances.
If when cleaning the windscreen with spe-
cial glass products, some drops fall on the
leather covering of the steering wheel/gear
lever knob remove them immediately and
then clean with water and neutral soap.
IMPORTANTTake the utmost care
when engaging the steering lock to prevent
scratching the leather covering.
INTERIOR PLASTIC PARTS
Clean plastic parts with a cloth
mositened with water and non-abrasive
neutral detergent. To remove grease or
hard stains, use appropriate products
designed to preserve the appearance of
components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument panel or
other plastic parts.
Upholstery of your car has
been designed to withstand
wear deriving from com-
mon use of the car. You are how-
ever recommended to avoid strong
and/or continuous scratching with
clothing accessories such as metal-
lic buckles, studs, Velcro fastenings
and the like, since these items cause
circumscribed stress of the cover
fabric that could lead to yarn break-
ing, and damage the cover as a con-
sequence.
