1.4 Petrol / 1.4 Turbo Petrol/LPG /
1.4 Turbo Multi Air / 1.3 JTD
M-2versions: pull the engine oil dipstick 1,
clean it with a lint-free cloth and insert
it again. Extract it again and check that
the level is between the MIN and MAX
marks on the dipstick.
Turbo TwinAir versions: engine oil
dipstick 1 is integral with the cap 2.
Unscrew the cap, clean the dipstick with a
lint-free cloth, reinsert the dipstick and
screw the cap back on. Unscrew the plug
again and check that the engine oil level is
between the MIN and MAX marks on the
dipstick.
Engine oil consumption
The maximum engine oil consumption is
usually 400 grams every 1000 km. When
the car is new, the engine needs to be run
in; therefore the engine oil consumption
can only be considered stabilised after
the first 5000 - 6000 km.

The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
IMPORTANT
37)Be careful not to confuse the various
types of fluids while topping up: they are not
compatible with each other! Topping up with
an unsuitable fluid could severely damage
your vehicle.
38)The oil level must never exceed the MAX
reference.
39)Do not add oil with specifications other
than those of the oil already in the engine.
40)Use a fluid of the same type as that
already present in the reservoir for any
topping up of the engine cooling system. The
fluid cannot be mixed with other types of
antifreeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
an Alfa Romeo Dealership.
41)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen, immediately
wash with water.
WARNING
130)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
131)Be very careful when working in the
engine compartment when the engine is hot:
you may get burned. Do not get too close to
the radiator cooling fan: the electric fan may
start; danger of injury. Scarves, ties and
other loose clothing might be pulled by
moving parts.
142
SERVICING AND MAINTENANCE

132)If the engine oil is being topped up, wait
for the engine to cool down before loosening
the filler cap, particularly for vehicles with
aluminium cap (where provided). WARNING:
risk of burns!
133)The cooling system is pressurised. If
necessary, only replace the plug with
another original or the operation of the
system may be adversely affected. Do not
remove the reservoir plug when the engine is
hot: you risk scalding yourself.
134)Do not travel with the windscreen
washer fluid reservoir empty: the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
135)Some commercial additives for
windscreen washer fluid are flammable. The
engine compartment contains hot
components which may start a fire.
136)Brake fluid is poisonous and highly
corrosive. In the event of accidental contact,
immediately wash the affected parts with
water and mild soap. Then rinse thoroughly.
Call a doctor immediately if swallowed.
137)The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral-based. Use of mineral
type fluids will damage the special rubber
seals of the braking system beyond repair.
IMPORTANT
2)Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters, we
advise you to contact an Alfa Romeo
Dealership.
3)Used transmission fluid contains
substances that are harmful to the
environment. You are advised to contact an
Alfa Romeo Dealership for oil changes.

If necessary, replace the battery with
another original battery with the same
specifications. Follow the battery
manufacturer's instructions for
maintenance.
USEFUL ADVICE FOR EXTENDING THE
LIFE OF YOUR BATTERY
To avoid draining your battery and make
it last longer, observe the following
instructions:
when you park the car, ensure that the
doors, tailgate and bonnet are closed
properly, to prevent any lights from
remaining on inside the passenger's
compartment;
switch off all roof lights inside the car:
the car is however equipped with a
system which switches all internal lights
off automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before performing any operation on
the electrical system, disconnect the
negative battery cable.
IMPORTANT If the charge level remains
under 50% for a long time, the battery is
damaged by sulphation, reducing its
capacity and efficiency at start-up.
The battery will also be more at risk of
freezing (this can happen as early as
-10°C). Refer to the "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.
If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.
WARNING
139)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
140)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
141)If the vehicle must remain unused for a
long time at a very low temperature, remove
the battery and take it to a warm place, to
avoid freezing.
142)When performing any operation on the
battery or near it, always protect your eyes
with special goggles.
IMPORTANT
43)Incorrect installation of electric and
electronic devices may cause severe damage
to your car. After purchasing your vehicle, if
you wish to install any accessories (e.g.
anti-theft, radio phone, etc.), go to an Alfa
Romeo Dealership, which will suggest the
most suitable devices and advise you
whether a higher capacity battery needs to
be installed.

SERVICING AND MAINTENANCE

IMPORTANT
4)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an Alfa Romeo
Dealership.
LIFTING THE VEHICLE
If the car needs to be jacked up, go to an
Alfa Romeo Dealership which is equipped
with shop jacks and jack arms.
IMPORTANT Be careful when positioning
the arm of the lift for versions with side
skirts.
BODYWORK
PRESERVING THE BODYWORK
44)
5)
Paint
Touch up abrasions and scratches
immediately to prevent the formation of
rust. Maintenance of paintwork consists
of washing the car: the frequency
depends on the conditions and
environment where the car is used. For
example, it is advisable to wash the
vehicle more often in areas with high
levels of atmospheric pollution or salted
roads.
On some versions the car may be
equipped, on request, with an exclusive
opaque paint on the roof which, in order
to be maintained intact, requires special
care: see the instructions in the warning.
45)
To correctly wash the vehicle, follow
these instructions:
if the vehicle is washed remove the
aerial from the roof;
if high pressure jets or cleaners are
used to wash the car, keep a distance of
at least 40 cm from the bodywork to
avoid damage or alteration. Bear in mind
that a build up of water could cause
damage to the car in the long term;
147

wash the bodywork using a low
pressure jet of water;
wipe a sponge with a slightly soapy
solution over the bodywork, frequently
rinsing the sponge;
rinse well with water and dry with a jet
of air or a chamois leather.
Dry the less visible parts (e.g. door
frames, bonnet, headlight frames, etc.)
with special care, as water may stagnate
more easily in these areas. Do not wash
the car after it has been left in the sun or
with the bonnet hot: this may alter the
shine of the paintwork.
Exterior plastic parts must be cleaned in
the same way as the rest of the vehicle.
IMPORTANT NOTES
Avoid parking under trees; the resin
dropped by trees makes the paintwork
go opaque and increases the possibility
of corrosion.
Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.
Windows
Use specific detergents and clean cloths
to prevent scratching or altering the
transparency.
IMPORTANT Wipe the rear window inside
gently with a cloth following the direction
of the filaments to avoid damaging the
heating device.
Front headlights
Use a soft cloth soaked in water and
detergent for washing cars.
IMPORTANT Never use aromatic
substances (e.g. petrol) or ketones (e.g.
acetone) for cleaning the plastic lenses
of the headlights.
IMPORTANT When cleaning with a
pressure washer, keep the water jet at
least 20 cm away from the headlights.
Engine compartment
At the end of every winter, wash the
engine compartment thoroughly, taking
care not to aim the jet of water directly at
the electronic control units or at the
windscreen wiper motors. Have this
operation performed at a specialised
workshop.
IMPORTANT The washing should take
place with the engine cold and the
ignition key in the STOP position. After
the washing operation, make sure that
the various protections (e.g. rubber caps
and guards) have not been removed or
damaged.
IMPORTANT
5)Detergents pollute the environment. Only
wash your vehicle in areas equipped to
collect and treat wastewater from this type
of activity.
IMPORTANT
44)In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle.
45)Avoid washing with rollers and/or
brushes in washing stations. Wash the
vehicle only by hand using neutral pH
detergents; dry it with a wet chamois leather.
Abrasive products and/or polishes should
not be used for cleaning the car. Bird
droppings must be washed off immediately
and thoroughly as the acid they contain is
particularly aggressive. Avoid (if at all
possible) parking the vehicle under trees;
remove vegetable resins immediately as,
when dried, it may only be possible to remove
them with abrasive products and/or polishes,
which is highly inadvisable as they could alter
the typical opaqueness of the paint. Do not
use pure windscreen washer fluid for
cleaning the front windscreen and rear
window; dilute it min. 50% with water. Only
use pure screen washer fluid when strictly
necessary due to outside temperature
conditions.
