WARRANTY BOOKLET
The
Warranty Booklet is delivered together with every new vehicle and contains the regulations tied to the services
given by Alfa Romeo Services and to the warranty conditions.
Correctly carrying out the scheduled services specified by the manufacturer is the best way to maintain the per-
formance, safety characteristics and low running costs of your vehicle. It is also necessary to maintain warranty
cover.
“Service” guide
This contains the Alfa Romeo Authorized Services. The services can be recognized by the presence of the Alfa
Romeo badge and logo.
The Alfa Romeo organization in Italy can be found in the telephone book under the letter “A” Alfa Romeo.
Not all the models described in this booklet are available in all countries. Only some of the fittings described in this booklet are
fitted as standard to the vehicle. The list of available accessories should be requested from Alfa Romeo Dealers.

ACCESSORY ELECTRICAL DEVICES
If after purchasing the car you wish to install accessories that need an electrical supply (with the risk of gradually draining
the battery), contact Alfa Romeo Authorised Services who will assess the overall electrical absorption and check whether the
car system is able to withstand the load required.

CODE CARD
Keep it in a safe place, not in the car. It is advisable to always keep the electronic code on the CODE card with you in case
emergency starting is necessary.
SCHEDULED SERVICING

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.

Any attempt to clean
the air cleaner may
cause serious engine
damage.
If they are not carried
out correctly and with
the due precautions, the
operations involving cleaner re-
placement described herein may
compromise the safety of the
car. This operation should be car-
ried out by Alfa Romeo Autho-
rized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
the electrical signals needed for correct
operation of the injection and ignition sys-
tem to the control unit.
It must therefore always be in perfect
conditions to ensure correct operation of
the engine, low consumption and exhaust
emission levels.When the car is habitu-
ally driven in dusty ar-
eas, the cleaner should
be changed at shorter intervals
than those given in the Pro-
grammed Maintenance Schedule.
IMPORTANT When topping up use
the special detergents available in the
shops ensuring that they contain antis-
cale and antifreeze properties.
If in doubt contact Alfa Romeo Autho-
rized Services who will be able to recom-
mend the most suitable products.
Do not travel with the
windscreen washer
reservoir empty: the action of the
windscreen washer is fundamental
for improving vision.
WARNING

219
DUST/POLLEN FILTER
The filter mechanically/electrostatically
filters the air provided that the windows
are shut.
The dust/pollen filter should be checked
over once a year by Alfa Romeo Autho-
rized Service station preferably at the be-
ginning of the summer.
If the vehicle is habitually driven in
cities, motorways or on dusty roads the
system should be checked over more of-
ten than specified in the Programmed
Maintenance Schedule.
IMPORTANT If the filter is not re-
placed the efficiency of the climate con-
trol system may be seriously compro-
mised.

side of the boot, protected by a cover.
On versions without navigation system
and without CD player, access to the bat-
tery is gained by slackening the knob
(A-fig. 14) and removing the battery
cover.

Periodically clean the wiper blades and
ensure that they are not damaged. If the
rubber blades are bent of worn in parts
they should be replaced, as follows:
– Press the tab (B) of the blade catch
spring and push the blade towards the
base of the arm (A).
– When the catch spring has been freed
from the curved top of the arm, withdraw
the blade from the arm through the slot. The spark plugs must be
changed at intervals
given in the Pro-
grammed Maintenance Schedule.
Only use spark plugs of the spec-
ified type (see table of “Fuel
Supply and Ignition” in the
“Technical specifications” chap-

equate, or the foreseen life is
not guaranteed inconveniences
may result.
