Romeo Dealership.
Engine oil consumption
57)
4)
The maximum engine oil consumption is
usually 0.55 pounds (250 grams) every
620 mi (1,000 km). When the vehicle is
new, the engine needs to be run in;
therefore the engine oil consumption can
only be considered stabilised after the
first 3,100 - 3,730 mi (5,000 -
6,000 km).
ENGINE COOLANT FLUID
145)
58)
If the level is too low, unscrew the cap of
reservoir 2 and add the fluid described in
the "Technical Specifications" chapter.
WASHER FLUID FOR WINDSCREEN/
HEADLIGHTS
146) 147)
The windscreen and headlights washer
fluid reservoir (where available) is
equipped with a telescopic filler.
If the level is too low, remove reservoir
cap 4 and lift the filler then add the fluid
described in the "Technical
Specifications" chapter.
IMPORTANT The headlight washing
system will not work if the liquid level is
low (situation indicated by the symbol on
the instrument panel display). The
windscreen washer will keep working. On
vehicles equipped with headlight
washers, Where provided, there is a
reference notch on the dipstick: ONLY
the windscreen/rear window washer
operates with the level below this
reference.
BRAKE FLUID
Check that the fluid is at the max. level. If
the liquid level in the tank is insufficient,
contact an Alfa Romeo Dealership to
have the system checked.

The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
USEFUL ADVICE FOR EXTENDING THE
LIFE OF YOUR BATTERY
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.
If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
147

influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to indicate
this. To carry out this procedure, simply
turn the steering wheel all the way from
one end to the other and then put it back
to the central position.
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 is also more prone to the risk of
freezing (at temperatures as high as 14
°F (-10°C)).BATTERY
148) 149) 150) 151)

6)
The battery 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.
Follow the battery manufacturer's
instructions for maintenance.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to indicate
this. To carry out this procedure, simply
turn the steering wheel all the way from

central position.
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 is also more prone to the risk of
freezing (at temperatures as high as 14
°F (-10°C)).
WARNING
142)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
143)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.
144)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!
145)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.
146)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.
147)Some commercial additives for
windscreen washer fluid are flammable. The
engine compartment contains hot
components which may start a fire.
148)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.

SERVICING AND CARE

149)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
150)If the vehicle 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.
151)When performing any operation on the
battery or near it, always protect your eyes
with special goggles.
IMPORTANT
55)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.
56)The oil level must never exceed the MAX
reference.
57)Do not add oil with specifications other
than those of the oil already in the engine.
58)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.
59)When you need to disconnect or remove
the battery, do not close the boot. In order to
avoid possible accidental closure, it is
recommended to place an obstacle (e.g. a
cloth) on the lock that would physically avoid
closure.
IMPORTANT
4)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.
5)Used transmission fluid contains
substances that are harmful to the
environment. You are advised to contact an
Alfa Romeo Dealership for oil changes.
6)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an Alfa Romeo
Dealership.
BATTERY RECHARGING
IMPORTANT NOTES
152) 153)
IMPORTANT Before using the charging
device, always make sure that it is
appropriate for the installed battery,
with constant voltage (below 14.8 V) and
low amperage (maximum 15 A).
IMPORTANT Recharge the battery in a
well ventilated environment.
IMPORTANT Never charge or recharge a
frozen battery: it may explode because
of the nitrogen trapped inside the ice
crystals.
IMPORTANT At all times while charging
or recharging the battery, make sure that
any sparks or open flames are kept
sufficiently far away from the battery.
IMPORTANT Before using any devices to
charge or to maintain the charge of the
battery, carefully follow the instructions
provided with the device in order to

AIR CONDITIONINGSYSTEM
MAINTENANCE
68) 69)
To ensure the best possible performance,
the air conditioning system must be
checked and undergo maintenance at an
Alfa Romeo Dealership at the beginning
of the summer.
WINDSCREEN WIPER
Raising the windscreen wiper blades
("Service position" function)
The "Service position" function allows the
driver to replace the windscreen wiper
blades more easily. It is also
recommended to activate this function
when it is snowing and to make it easier
to remove any dirt deposits in the area
where the blades are normally
positioned, when washing.
Activation of the function
To activate this function disable the
windscreen wiper (ring nut fig. 151 in
positionO) before setting the ignition
device to STOP.This function can only be activated within
2 minutes of setting the ignition device
to STOP.
To activate this function, move the lever
upwards (unstable position) for at least
three seconds.
If, after using the function, the ignition
device is set back to ON with the blades
in a position other than rest position (at
the base of the windscreen), they will only
return to rest position following a
command given using the stalk (stalk
upwards, into unstable position) or when
a speed of 3 mph (5 km/h) is exceeded.
Replacing the windscreen wiper blades
Proceed as follows:
raise the wiper arm, press tab
fig. 152 of the attachment spring and
remove the blade from the arm;
fit the new blade, inserting the tab in
the dedicated housing in the arm and
checking that it is locked;
lower the wiper arm onto the
windscreen.
IMPORTANT Do not operate the
windscreen wiper with the blades lifted
from the windscreen.
Windscreen washer
The window washer nozzles are fixed. If
there is no jet of fluid, firstly check that
there is fluid in the reservoir (see
paragraph “Engine compartment” in this
chapter).
Then check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.

WARNING
154)The air intake system (air cleaner,
rubber hoses, etc.) can be a protection in the
case of blowbacks from the engine. DO NOT
REMOVE this system unless you need to
carry out repair or servicing operations.
Before starting the engine, ensure that the
system has not been removed: failure to
observe this precaution may result in serious
injury.
155)Exhaust emissions are very dangerous,
and may be lethal. They contain carbon
monoxide, a colourless, odourless gas which
can cause fainting and poisoning if inhaled.
156)The exhaust system may reach high
temperatures and may cause a fire if the
vehicle is parked on flammable material. Dry
grass or leaves can also catch fire if they
come into contact with the exhaust system.
Do not park or use the vehicle in a place in
which the exhaust system might come into
contact with flammable material.
IMPORTANT
61)Incorrect servicing of the vehicle or
failure to carry out operations or repairs
(when necessary) may lead to more
expensive repairs, damage to other
components or have a negative impact on
the vehicle performance. Have any
malfunction inspected immediately by an
Alfa Romeo Dealership.62)The vehicle is equipped with fluids which
are optimised or protecting its performance
and life and extending service intervals. Do
not use chemicals for washing these
components since they may damage the
engine, the gearbox or the climate control
system. This damage is not covered by the
vehicle’s warranty. If any component needs
to be washed due to malfunctioning, use only
the specific liquid for that procedure.
63)An excessive or insufficient amount of
oil inside the base is extremely damaging to
the engine. Make sure it is always at an
adequate level.
64)Vehicles equipped with catalytic
converter must be fuelled only with unleaded
petrol. Leaded petrol would permanently
damage the catalytic converter and
eliminate its ability to reduce polluting
emissions, seriously compromising the
engine performance, which would be
irreparably damaged. If the engine does not
work correctly, especially if it starts
irregularly or if there is a reduction of its
performance, immediately go to an Alfa
Romeo Dealership. Prolonged and faulty
operation of the engine may cause
overheating of the converter and, as a
consequence, possible damage to the
converter and the vehicle.
65)Using a gearbox fluid different from that
approved may compromise gearshifting
quality and/or cause vibration of the
gearbox itself.66)It is recommended to have the vehicle
serviced by an Alfa Romeo Dealership. When
carrying out normal periodic operations and
small servicing interventions personally on
the vehicle, it is recommended to use
suitable equipment, genuine spare parts and
the necessary fluids. Do not carry out any
interventions if you don't have the necessary
experience.
67)When you need to disconnect or remove
the battery, do not close the boot. In order to
avoid possible accidental closure, it is
recommended to place an obstacle (e.g. a
cloth) on the lock that would physically avoid
closure.
68)Always require the use of only
compressor coolants and lubricants
approved and suitable for the specific air
conditioning system fitted on the vehicle.
Some non-approved coolants are flammable
and may explode, with the risk of injuries. The
use of non-approved coolants or lubricants
may adversely affect system efficiency,
leading to expensive repairs.
69)The air conditioner system contains
coolant under high pressure: to avoid injuries
to people or damage to the system, any
coolant addition or repair that requires to
disconnect the cables must be carried out by
an Alfa Romeo Dealership.
152
SERVICING AND CARE

transmissions, automatic activation of P
(Park mode) must be disabled. You have
to switch off the engine in the following
conditions: car stopped, gear in N
(Neutral), press the starter button. The
car will remain in N (Neutral) for
15 minutes, after which P (Park) mode
will be activated.
IMPORTANT
71)In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle.
72)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.
IMPORTANT
7)Detergents pollute the environment. Only
wash your vehicle in areas equipped to
collect and treat wastewater from this type
of activity.
