FUSES AND RELAYS IN THE
CONTROL UNIT
The fuses for the main devices are
housed in a control unit under the dash-
board, to the left of the steering column.
Access to it is gained slackening the
knob (A-fig. 84) and lowering the pan-
el (B).
The graphic symbols which distinguish
the main electric component correspond-
ing to each fuse are given on a label on
the inner wall of the panel.In the upper part of the control unit
there is a pincer (C-fig. 85) for remov-
ing fuses.
At the sides of the control unit there are
some spare fuses (C-fig. 86); after re-
placing a fuse you are advised to replen-
ish the stock of fuses when they are
used.
The systems and devices protected by
fuses are in listed in the tables on next
pages.The circuits operated by relays are the
following (fig. 86):
A- Switch discharge relay
B- Headlight washer timer.

198IN THE EVENT
OF AN ACCIDENT
– It is important to keep calm.
– If you are not directly involved, stop
at a distance of at least ten metres from
the accident.
– On the motorway stop without ob-
structing the emergency lane.
– Turn off the engine and switch on the
hazard warning lights.
– At night, light the place of the acci-
dent with your headlights.
– Take care not to put yourself in dan-
ger of being run over.
– Signal the accident placing the reflect-
ing triangle plainly in view at the regula-
tion distance.
– Call the rescue organisation giving in-
formation as exact as possible. On motor-
ways use the special call boxes.
– In motorway pileups, especially with
poor visibility, the risk exists of being in-
volved in other crashes. Leave the vehi-
cle immediately and go over the guard
rail. The car is to be lifted
positioning the jack or
the workshop lift arm
plate only in the points shown
(1-2 fig. 100).
Between the lift plate and the
body interpose a rubber pad
with a maximum size of 60x60
mm and maximum thickness of
30 mm. The pad should insert in
the special recess on the under
door panel, without interfering
with it.
USING AN ARM LIFT OR
WORKSHOP LIFT
The vehicle must only be lifted laterally
positioning the ends of the arms or the
workshop lift in the areas (1-2) illustrat-
ed, approx. 30 cm from the profile of the
wheelhouse (fig. 100).

IMPORTANT - Engine oil
Change the engine oil more frequently
than stated in the Scheduled Mainte-
nance Programme if the car is used pre-
vailingly in one of the following particular-
ly harsh conditions:
– trailer or caravan towing
– dusty roads
– short, repeated journeys (less than 7-
8 km) with an outside temperature of be-
low freezing point.
– engine idling frequently or driving
long distances at low speed (e.g. taxi or
door-to-door deliveries) or in the case of
prolonged inactivity.
IMPORTANT - Air cleaner
Using the car on dusty roads, change
the air cleaner more frequently than stat-
ed in the Scheduled Maintenance Pro-
gramme.
For any doubts about the intervals be-
tween engine oil and air cleaner changes
in relation to how the car is used, contact
Authorised Alfa Romeo Services.IMPORTANT - Fuel oil filter
The variety of the degree of purity of
the fuel oil in commerce may make it
necessary to change the fuel oil filter
more frequently than stated in the Sched-
uled Maintenance Programme. If the en-
gine is “sobbing” it is a sign that the fil-
ter needs changing.
IMPORTANT - Pollen filter
If the car is used frequently in dusty or
heavily polluted environments, you are
recommended to change the activated
carbon filtering element more frequently;
in particular, it should be changed if a
lower flow of air admitted to the passen-
ger compartment is noted.IMPORTANT - Batteries
You are recommended to have the bat-
tery charge conditions checked, prefer-
ably at the onset of winter, to avoid the
possibility of freezing the electrolyte.
This check should be carried out more
frequently if the car is used prevailingly
for short journeys, or if it is fitted with
services that absorb high amounts of cur-
rent permanently with the ignition key
off, especially if installed in the after mar-
ket.
In the case of use of the car in hot cli-
mates or particularly harsh conditions, it
is wise to check the level of the battery
fluid (electrolyte) at more frequent inter-
vals than stated in the Scheduled Mainte-
nance Programme.
IMPORTANT - Remote control
If when pressing the remote control but-
ton of the key, the operating led on the
key flashes briefly only once, the battery
need replacing with other of the same
type.

211
PROTECTIVE SHIELD UNDER
ENGINE
The car is fitted with a protective shield
under the engine.
IMPORTANTWhen changing the en-
gine oil and filter, checking and changing
the gearbox and differential oil, this pro-
tection should be removed. This operation
should be carried out by Alfa Romeo Au-
thorized Services.
CHECKING ENGINE OIL LEVEL
Fig. 3:3.2 V6 24V version
Fig. 4:JTD 20V Multijet version
The engine oil level should be checked
when the vehicle is standing on a level
surface a few minutes (about 5) after the
engine has been switched off.
Remove the dipstick (A), clean it, then
re-insert it completely, remove it once again
and check that the level is between the
MIN and MAX marks on the dipstick.The interval between the MIN and MAX
marks corresponds to approximately 1
litre of oil.
Max. engine oil consumption is usually
400 grams every 1000 km.
When the car is new, the engine needs
to run in, therefore the engine oil con-
sumption can only be considered sta-
bilised after the first 5000-6000 km.

CHECKING POWER STEERING
OIL LEVEL
Fig. 8:JTD 20V Multijet version
Fig. 9:JTD 20V Multijet version
Fig. 10:3.2 V6 24V version
Check that the oil in the reservoir is at
the maximum level.
This operation must be carried out with
the car on level ground and when the en-
gine is stationary and cold.
fig. 8 - JTD 20V Multijet versionfig. 9 - JTD 20V Multijet versionfig. 10 - 3.2 V6 24V version On JTD 20V Multijet versions access to
the reservoir is gained by removing the cov-
er (A-fig. 8) after turning the fastening
pins withdraw the tube (B-fig. 9).
Slacken the cap (C-fig. 9-10) and
check that the level corresponds to the
reference notch of the maximum level on
the dipstick which is an integral part of
the cap.
TOPPING UP THE POWER
STEERING OIL
If the level of the oil in the power steer-
ing reservoir falls below the specified lev-
el, top up only with one of the products
listed in he table of “Fluids and lubri-
cants” in the “Technical specifications”
chapter as follows.
– Start the engine and allow the oil in
the reservoir to settle.
– When the engine is running turn the
steering wheel lock to lock a few times.
– Top up the MAX level notch and then
replace the cover.
