PERIODIC CHECKS
Every 1,000 km or before long
journeys, check and, if necessary, top
up the following:
❒engine coolant, brake fluid and
windscreen washer fluid level;
❒tyre inflation pressure and condition;
❒operation of lighting system
(headlamps, direction indicators,
hazard warning lights, etc.);

system and positioning/wear of
windscreen/rear window wiper
blades
Check and top up, if required, the
engine oil level every 3,000 km.
HEAVY-DUTY USE OF
THE CAR
If the car is used mainly under one of
the following conditions:
❒towing a trailer or caravan;
❒dusty roads;
❒short, repeated journeys (less than
7-8 km) at sub-zero outside
temperatures;
❒engine often idling or driving long
distances at low speeds or long
periods of idleness;
the following checks must be carried
out more often than indicated in the
Scheduled Servicing Plan:
❒check front disc brake pad
conditions and wear;
❒check cleanliness of bonnet and boot
locks, cleanliness and lubrication of
linkage;
❒visually inspect conditions of: engine,
gearbox, transmission, pipes and
hoses (exhaust - fuel system -
brakes) and rubber elements (boots -
sleeves - bushes - etc.);
❒check battery charge and battery
fluid level (electrolyte);
❒visually inspect condition of the
accessory drive belts;❒check and, if necessary, change
engine oil and replace oil filter;

SERVICING AND MAINTENANCE

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.

SERVICING AND MAINTENANCE

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".
35)144) 145)
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.

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.
