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.
BATTERY RECHARGING
IMPORTANT The battery recharging
procedure is given as information only. To
carry out this operation contact an Alfa
Romeo Dealership.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver's side door, wait at least one
minute before disconnecting and then
reconnecting the electrical supply to the
battery.
Charging should be slow at a low ampere
rating for approximately 24 hours.
Charging for a longer time may damage
the battery.
IMPORTANT The cables of the electrical
system must be correctly reconnected to
the battery, i.e. the positive cable (+) to
the positive terminal and the negative
cable (–) to the negative terminal. The
battery terminals are marked with the
positive (+) and negative (–) symbols, and
are shown on the battery cover. The
battery terminals must also be
corrosion-free and firmly secured to the
terminals. If a "quick-type" battery
charger is used with the battery fitted on
the vehicle, before connecting it
disconnect both cables of the battery
itself. Do not use a "quick-type" battery
charger to provide the starting voltage.
The cables of the electrical system must

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.
