206 ANNUAL INSPECTION
PLAN
An annual inspection plan has
been established for cars that cov-
er less than 20,000 km a year
(e.g. 10,000 km). It consists of
the following:
– Checking the condition/wear of tyres,
and adjusting pressure (including the com-
pact spare wheel, where applicable).
– Checking the lighting system (head-
lights, turn indicators, hazard warning
lights, boot light, passenger compart-
ment, warning lights of instrument panel,
etc.).
– Checking the working order of the
windscreen wiper-washer and adjusting
the nozzles.
– Checking the positioning/wear of the
windscreen wipers.
– Checking the condition and wear of
the front brake pad.– Sight inspect the conditions of: en-
gine, gearbox, transmission, pipes and
hoses (exhaust - fuel - brakes), rubber
parts (boots, sleeves, bushes, etc.).
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication.
– Check battery charge and fluid level
(electrolyte).
– Visually checking the condition of the
belts and various controls.
– Checking and topping up, if neces-
sary, the level of liquids (coolant, brake
fluid, windscreen washer fluid, battery
etc.).
– Change engine oil and oil filter, if re-
quired.
– Check and replace pollen filter, if re-
quired.
– Check and replace air cleaner, if re-
quired.
ADDITIONAL OPERATIONS
Every 1000 kmor before long jour-
neys check and if necessary top up:
– the engine coolant fluid level
– brake fluid/hydraulic clutch control
fluid level
– power steering fluid level
– windscreen washer and headlamp
washer fluid level
– tyre pressure and conditions.
– check light system operation (head-
lights, direction indicators, hazard lights,
etc.).
– check windscreen wiper/washer op-
eration and windscreen/rear window
blade position/wear.
Every 3000 kmcheck the level of
the engine oil and top up if necessary.
Every 5000 km(only for fuel oil en-
gines): drain the condensation water
from the filter. You are recommended to
use products of the FL Selenia, de-
signed and developed expressly for Alfa
Romeo cars (see the table “Fluids and lu-
bricants” in the Technical specifications”
chapter).

When the cap (B) is
screwed off the reser-
voir ensure that the
electrical connections are not dis-
connected. Make sure that the
highly corrosive brake fluid
does not drip onto the paint-
work. If it does, wash it off
immediately with water.
IMPORTANT Contact Alfa Romeo Au-
thorized Services for maintenance and re-
pair operations.Oil consumption is very
low; if topping up again
is needed shortly after-
wards, have the system checked
for possible leaks by Alfa Romeo
Authorized services.
CHECKING AND TOPPING UP
THE BRAKE AND CLUTCH
FLUID
(fig. 11)
Check that the fluid level in the reservoir
is at maximum. Top up with the brake flu-
id specified in the table “Fluids and lubri-
cants” (see section “Technical Specifica-
tions ").
NOTEClean accurately the tank cap A
and the surrounding surface. When open-
ing the cap take the utmost care to pre-
vent impurities entering the tank. When
topping up, always use a funnel with
built-in filter with mesh equal to or lower
than 0.12 mm. On JTD 20V Multijet versions insert the
tube on the cap and refit the cover fasten-
ing with the three screws.
Do not allow power
steering fluid to touch hot
engine parts: it is inflammable.
WARNING

IMPORTANTFor this operation it is
however recommended to contact Alfa
Romeo Authorised Services.
From time to time check the instrument
panel warning light by pressing cover (B)
of the reservoir (A) (with the ignition
key at MAR) the instrument warning
panel light
xshould come on.

222
– Before doing any work on the electric
system, disconnect the battery negative
terminal.
If after purchasing the car, you wish to
install electrical accessories which need a
permanent electrical supply (alarm,
hands-free phone, radio-navigator with
satellite anti-theft function, etc.) contact
Authorised Alfa Romeo Services whose
qualified personnel, in addition to sug-
gesting the most suitable devices from
Lineaccessori will be able to evaluate the
total electrical absorption, checking
whether the car’s electric system is able
to support the load required or whether a
battery with higher capacity is necessary.
In fact, these devices continue to absorb
current with the ignition key off (car
parked, engine off) and may gradually
drain the battery. IMPORTANT A battery kept at below
50% of its capacity is damaged by sul-
phation, the capacity is reduced and start-
ing is difficult, there is also more possibili-
ty of freezing (this can occur at –10°C).
In the event of a prolonged stop, refer to
“Vehicle inactivity”.
USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERY
To avoid quickly draining the battery
and to preserve its operating conditions
over the course of time, carefully follow
the instructions below.
– The terminals must always be tight-
ened.
– As far as possible avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard warning lights,
parking lights, etc.).
– When leaving the vehicle parked in a
garage, make sure that the doors, bon-
net, boot and interior lids are properly
shut to prevent lights from staying on.
The fluid contained in the
battery is poisonous and
corrosive. Avoid contact with the
skin or eyes. The battery should be
charged in a ventilated place away
from naked flames or possible
sources of sparks: danger of ex-
plosion and fire.
WARNING
Never attempt to charge
a frozen battery before
thawing it, the danger of explosion
exists. If it has frozen, always
check that the inside elements are
not broken (risk of short circuit)
and that the body is not cracked,
with the risk of acid coming out
which is poisonous and corrosive.
WARNING

225
– Application of enamels with greater
resistance to atmospheric pollutants.
– Adoption of “open” boxed parts to
prevent condensation from triggering cor-
rosion from the inside.
The underbody is treated with the appli-
cation of a special protective material.
If this protective layer requires restora-
tion the exhaust system, lambda probe
and catalytic converter must be left free
of any wax, oil, plastic and/or inflamma-
ble product.
This should therefore be carried out by
Alfa Romeo Authorized Services.SPRAY JETS
Make sure that the windscreen and
headlight washer jets deliver a jet of fluid
which is adequate and correctly directed.
If the spray devices are not working
check that the supply circuit is not
blocked. If necessary unclog the nozzles
using a needle.
BODYWORK
PROTECTION FROM
ATMOSPHERIC AGENTS
Alfa Romeo employs manufacturing
technologies which are designed to pro-
tect the bodywork against chemical corro-
sion caused by various factors, for exam-
ple:
– atmospheric pollution.
– Salty air and humidity (coastal areas,
hot-humid climates).
– Road surfaces covered with salt and
de-icing products during the winter.
To further increase resistance against
corrosion the following procedures have
been adopted:
– painting system and paint products
which render the vehicle particularly resis-
tant to corrosion and abrasion.
– Wide use of sheet metal which is ex-
tremely resistant to corrosion.
– Spraying of the underbody, engine
bay, wheel arches and boxed parts with
suitable products which adhere strongly
to the metal parts and have a high pro-
tection capability.

LIGHTS SWITCH (fig. 3)
The device and services controlled by
the levers on the steering wheel can only
be activated when the ignition key is in
theMARposition (except the parking
lights which can always be switched on).Lights switched off
When the pointer on the knurled ring
(A) is opposite the symbol O, the exter-
nal lights are switched off.
Sidelights
The sidelights are switched on by turn-
ing the knurled ring (A) from Oto
6.
The
3warning light on the instru-
ment panel will come on at the same
time.
Dipped-beam headlights
These are switched on by turning the
knurled ring (A) from
6to2.
Parking lights
When the pointer of the switch (A) cor-
responds with the
Fsymbol, the side
lights stay on regardless of the position of
the ignition key.
