ENGINE OIL
Check that the oil level is between the
MIN and MAX references on the
dipstick A.
If the oil level is near or under the MIN
reference, add oil through the filler B
until it reaches the MAX reference.
140)32)
Take out the engine oil dipstick A, clean
it with a lint-free cloth and reinsert it.
Extract it again and check that the level
is between the MIN and MAX marks
on the dipstick.Engine oil consumption
33)3)
The maximum engine oil consumption
is usually 400 grams every 1,000 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 5,000 - 6,000
km.

ENGINE COOLANT
If the level is too low, unscrew reservoir
cap C and add the fluid described in
the "Technical Specifications" section.
34)141)
WINDSCREEN/REAR
WINDOW WASHER FLUID
If the level is too low, lift reservoir cap D
and add the fluid described in the
chapter "Technical Specifications".
142) 143)
IMPORTANT The headlight washer
system will not operate when the fluid
level is low, even though the
windscreen/rear window washer
continues to operate. For versions/
markets, where provided, there is
a reference notch E on the dipstick (see
previous pages): ONLY the
windscreen/rear window wiper
operates with the level below this
reference.
BRAKE FLUID
Check that the fluid is at the max. level.
If the fluid level in the reservoir is too
low, undo reservoir cap E and add the
fluid described in the chapter "Technical
Specifications".

ALFA TCT ACTIVATION
SYSTEM OIL
(for versions/markets, where provided)
The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
4)
IMPORTANT
31) 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
car.
32) The oil level should never exceed
the MAX mark.
33) Do not add oil with specifications
other than those of the oil already
in the engine.34) PARAFLU
UPanti-freeze fluid is
used in the engine cooling
system; use the same fluid type as
that already in the cooling system
when topping up. PARAFLU
UP
may not be mixed with other types
of anti-freeze fluids. In the event
of topping up with an unsuitable
product, under no circumstances
start the engine and contact an
Alfa Romeo Dealership.
35) Avoid allowing brake fluid, which
is extremely corrosive, to come
into contact with painted areas.
Should it happen, wash
immediately with water.
WARNING
138) Never smoke when performing
operations in the engine
compartment. Flammable gases
and fumes may be present and
risk igniting.
139) Be very careful when working in
the engine compartment when
the engine is hot: you may get
burned.
209

140) If the engine oil is being topped
up, wait for the engine to cool
down before loosening the filler
plug, particularly for cars with
aluminium plug (for versions/
markets, where provided).
WARNING: risk of burns!
141) 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
burns.
142) Do not travel with the
windscreen washer 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.
143) Certain commercial additives
for windscreen washer fluids are
inflammable. The engine
compartment contains hot
components which may set it on
fire.144) 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.
145) The symbol
on the container
indicates a synthetic brake fluid,
which is different from a mineral
fluid. Using a mineral-type fluid
will damage the special rubber
seals of the braking system
beyond repair.
IMPORTANT
3) Used engine oil and oil filters
contain substances which are
harmful to the environment. You
are advised to contact an Alfa
Romeo Dealership to have the oil
and filters changed.
4) Used transmission fluid contains
substances that are harmful to
the environment. You are advised
to contact an Alfa Romeo
Dealership for oil changes.

BATTERY
Battery F (see previous pages) does not
require the electrolyte to be topped up
with distilled water. A periodic check
carried out at an Alfa Romeo Dealership
is, however, necessary to check
efficiency.
REPLACING THE
BATTERY
146) 147) 148) 149)
36)
5)
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. 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 negative battery cable.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. Thewarning light
switches on to indicate this. To carry
out this procedure, simply turn the
steering wheel all the way from one end
to the other or drive in a straight line
for about a hundred metres.
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 paragraph "Car
inactivity" in "Starting and driving"
chapter if the car 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
146) Battery liquid is poisonous and
corrosive. Avoid contact with the
skin and eyes. Keep naked flames
and sources of sparks away from
the battery: risk of explosion and
fire.
147) Using the battery with
insufficient fluid irreparably
damages the battery and may
cause an explosion.
148) If the car 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.
211

IMPORTANT
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 ketenes (e.g.
acetone) for cleaning the plastic lenses
of the front 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
6) Detergents cause water pollution.
Only wash your car in areas
equipped to collect and treat
wastewater from this type
of activity.
IMPORTANT
38) In order to preserve the aesthetic
appearance of the paint abrasive
products and/or polishes should
not be used for cleaning the car.
