KNOWING THE INSTRUMENT PANEL

STORING THE CAR
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal and check the battery
charge. Repeat this check once
every three months during storage;
❒if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glasses;
❒slightly open the windows;❒cover the car with a cloth or
perforated plastic sheet. Do not use
compact plastic sheets which do
not allow humidity to evaporate from
the surface of the car.
❒inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
❒do not drain the engine cooling
system;
❒Any time the car is left inactive for
two weeks or more, operate the
air conditioning system with engine
idling for at least 5 minutes, setting
external air and with fan at maximum
speed. This operation will ensure a
suitable lubrication to minimise
possibility of damage to the
compressor when the system is
operated again.
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.

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.
