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;

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:

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.
133)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)134)
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.
135) 136)
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)137) 138)
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
131)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
132)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.
133)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!
135

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
6)Detergents pollute the environment. Only
wash your vehicle in areas equipped to
collect and treat wastewater from this type
of activity.
IMPORTANT
48)In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle.
49)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.
INTERIOR
144) 145) 146)
Periodically check the cleanliness of the
interior, beneath the mats, which could
cause oxidation of the sheet metal.
SEATS AND FABRIC PARTS
Remove dust with a soft brush or a
vacuum cleaner. It is advisable to use a
moist brush on velvet upholstery. Rub the
seats with a sponge moistened with a
solution of water and neutral detergent.
LEATHER SEATS
(for versions/markets, where provided)
Remove the dry dirt with a chamois or
slightly damp cloth, without exerting too
much pressure. Remove any liquid or
grease stains using an absorbent dry
cloth, without rubbing. Then clean with a
soft cloth or buckskin cloth dampened
with water and mild soap. If the stain
persists, use specific products and
observe the instructions carefully.
IMPORTANT Never use alcohol. Make
sure that the cleaning products used
contain no alcohol or alcohol derivatives,
even in small quantities.
