WARNING: Once you have carried out the last intervention in the table, continue with the scheduled servicing, maintaining the
frequency indicated in the plan by marking each operation with a dot or dedicated note.
Warning: simply restarting the maintenance from the start of the plan may cause the allowed interval to be exceeded for some
operations!

(2) Check to be carried out every year for cars on the road in countries with particularly severe climates (cold countries).
(3) The actual interval for changing engine oil and replacing the engine oil filter depends on the vehicle usage conditions and is signalled by the warning light or message in
the instrument panel. In any case, it must never exceed 2 years. Where the car is used mostly in urban settings you need to replace the engine oil filter every year.

SERVICING AND MAINTENANCE

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
(headlights, direction indicators, hazard
warning lights, etc.);
operation of screen wash/wipe system
and positioning/wear of windscreen/
rearscreen wiper blades
Check and top up, if required, the engine
oil level every 3,000 km.
IMPORTANT To find out the correct oil
quantity, always check using the dipstick.
Carry out the check with the vehicle
parked on level ground.
DEMANDING USE OF THE CAR
If the vehicle 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 inactivity;
the following checks must be carried out
more often than indicated in the
Scheduled Servicing Plan:
check front disc brake pad condition
and wear;
check cleanliness of bonnet and
luggage compartment locks, cleanliness
and lubrication of linkage;
visually inspect condition 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 conditions of the
accessory drive belts;
check and, if necessary, change engine
oil and replace oil filter;
check and, if necessary, replace pollen
filter;
check and, if necessary, replace air
cleaner.

SERVICING AND MAINTENANCE

ENGINE OIL
Check that the oil level is between the
MIN and MAX references on the dipstick
3.
If the level of the oil is close to or below
the MIN mark, add oil via the filler fitting
2 until the MAX mark is reached.
131)42)
Take out the engine oil dipstick 3, 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
43)3)
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.
ENGINE COOLANT FLUID
If the level is too low, unscrew the cap
1 of reservoir and add the fluid described
in the "Technical Specifications" chapter.
44)132)
WINDSCREEN / REAR WINDOW
WASHING FLUID
If the level is too low, raise the reservoir
cap 6 and add the fluid described in the
"Technical Specifications" chapter.
133) 134)
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 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 the reservoir cap 4 and add the fluid
described in the "Technical
Specifications" chapter.
45)135) 136)
AUTOMATIC TRANSMISSION
ACTIVATIONSYSTEM OIL
(for versions/markets, where provided)
The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
4)
IMPORTANT
41)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.42)The oil level must never exceed the MAX
reference.
43)Do not add oil with specifications other
than those of the oil already in the engine.
44)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.
45)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen, immediately
wash with water.
WARNING
129)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
130)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.
131)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!
139

HEADLIGHT WASHERS
(for versions/markets, where provided)
These are located within the front
bumper.
They are activated when the dipped
beam and/or main beam headlights are
on and the windscreen washer is
activated.
Check the correct condition and
cleanliness of nozzles at regular
intervals.
WARNING
137)Driving with worn windscreen/rear
window wiper blades is a serious hazard,
because visibility is reduced in bad weather.
IMPORTANT
46)Do not operate the windscreen wiper
with the blades lifted from the windscreen.
BATTERY
The battery 5 (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.
INSPECTING THE CHARGE AND THE
ELECTROLYTE LEVEL
138) 139) 140) 141)
47)
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. 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 Every time the battery is
disconnected, the steering must be
initialised. This is indicated by the
appearance of the icon
. 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 "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.
