– Check the operation of the horn.
– Check the operation and degree of
wear of the windscreen wipers.
– Check the operation of the external
lights and if necessary, clean the light
units.
– Above all when driving at night,
check the alignment of headlight beams
before starting off.
– Check that no oil or other liquid is
leaking out under the car.
– Ensure that luggage is stowed away
correctly.
– Ensure that, in addition to yourself,
all passengers have fastened their seat
belts.
– Ensure that the handbrake is re-
leased and that the warning lights on the
instrument panel do not indicate a mal-
function. To avoid accidental movements
of the car, disengage the handbrake
keeping the brake pedal pressed.
The following should also be noted:
– Long distances should be tackled
when in good health and should where
possible be programmed, especially when
the roads are busy.– A light meal containing easily assimil-
able foods will help keep reflexes ready
and aid concentration for a safe journey.– Use the direction indicators when
changing direction.
– Switch on the external lights at sun-
set.
– Keep a safe distance from the vehicle
in front. A “safe” distance will vary ac-
cording to the speed of the vehicle,
weather conditions and road-traffic condi-
tions.
– Never drive with one hand resting on
the gear lever. The involuntary movement
of the gear lever which this causes, even
if slight, will cause avoidable wear to the
internal elements of the gearbox.
– Never drive with the gearbox in neu-
tral.
– Do not drive with your foot resting on
the clutch pedal as this habit leads to
rapid wearing of the clutch.
– Do not drive for long periods without
a break. During a break get out of the ve-
hicle and move around a bit to shake off
drowsiness.
– Ensure that the air in the vehicle is
changed constantly using the many possi-
bilities offered by the heating-ventilation
and climate control system.
WHEN TRAVELLING
– Driving with care also means being
able to predict the actions of other road
users, respecting the speed limits and oc-
cupying the near-side lane on motorways.
Driving under the influ-
ence of alcohol, drugs
and/or some medicines is highly
dangerous.
Never drive when drunk or under
the effect of drugs or medicines.
WARNING

139
DRIVING UNDER ADVERSE
WEATHER CONDITIONS
Rain and fog can be extremely danger-
ous if the style of driving is not adapted
to suit these conditions. Some sugges-
tions are given below:
– if the road is wet, the friction be-
tween wheel and asphalt is greatly re-
duced thus increasing the stopping dis-
tance and decreasing road holding when
cornering.
Reduce speed and keep further back
from the vehicle in front.
– Heavy rain and fog reduce visibility.
Headlights should be switched on as the
road traffic laws and common sense dic-
tate, above all to render yourself visible
to others.
– Do not drive over puddles or flooded
roads at high speed as the aquaplaning
phenomenon may cause you to loose
control over the vehicle.
– If visibility is already reduced prevent
it from worsening by ensuring that the
windows do not steam up. Use the heat-
ing-ventilation controls as indicated in the
chapter “Know your vehicle”.– Check the condition of the windscreen
wiper blades.
– If fog is very thick avoid travelling
where possible. If travelling cannot be
avoided drive with extreme care and
moderate your speed. Avoid overtaking.
– If the vehicle is forced to stop owing
to a malfunction or zero visibility condi-
tions, pull off the road, switch on the haz-
ard warning lights and if possible, the
dipped-beam headlights.
MOUNTAIN DRIVING
Mountain driving requires a greater de-
gree of concentration. Some practical
hints follow:
– Before driving off check the level of
fluids (engine oil, brakes, coolant) and
the state of the tyres.
– When travelling down hill use the en-
gine braking by engaging lower gears to
prevent the brakes from overheating.
– Never coast downhill with the engine
off or in neutral and especially not with
the ignition key removed.
– Drive at a moderate speed and avoid
cutting corners.– Remember that overtaking uphill is
slower and therefore requires a greater
length of clear road. If you are being
overtaken on a hill move over to enable
the other vehicle to pass in safety.
WINTER DRIVING
If the temperature falls below 0°C or in
the presence of snow or ice the following
recommendations should be followed:
– Before driving off check that the
windscreen wipers are not frozen to the
windscreen.
– Remove the snow from the air intake
(grille) at the base of the windscreen.
– Do not stop long on deep snow with
the engine running: the snow might di-
vert the exhaust gas carbon monoxide in-
to the passenger compartment.
– Ensure that brakes and tyres are in
perfect working order.
–Ensure that the detergent liquid locat-
ed in the windscreen/headlight washers
has been topped up with anti-freeze and
anti-scale additives.
– Use engine braking where possible
and avoid abrupt braking.

145
To ensure uniform wear between the
tyres on the front axle and those on the
rear axle, the tyres should be switched
around every 10,000 - 15,000 km keep-
ing the tyres on the same side of the ve-
hicle to avoid inverting the direction of ro-
tation (fig. 1).Note for one way tyres: There
are arrows on the side of one-way tyres
indicating the direction of rotation. When
a wheel is changed (for example after a
puncture, the direction of the arrow on
the spare wheel might not coincide with
the direction of rotation of the wheel to
be changed. Even in these conditions the
tyre is still safe but you are advised to
have the tyre repaired and refitted as
soon as possible, because top perfor-
mance is obtained when all the wheels
turn in the direction of the arrow.Tyre pressure and wear
The correct tyre pressure will not only
ensure that your tyres last longer but will
also make your vehicle safer as they have
a direct influence over road holding.
The pressure of each tyre, including that
of the spare tyre should be checked regu-
larly and always before a long journey.
The tyres should be checked when cold
using a pressure gauge and inflated to
the pressure given in the chapter “Techni-
cal specifications”.
Incorrect tyre pressure causes tyre wear
(fig. 2):
Do not cross the tyres
over.

148ECONOMY AND
ENVIRONMENT-
FRIENDLY DRIVING
How you use and how you drive your
vehicle directly influence fuel consump-
tion and environmental impact.
By following a few simple guidelines
and without incising on the “liveliness”
of the vehicle, it is possible to avoid dam-
aging the environment and often, at the
same time, to limit fuel consumption.
The following helpful suggestions will al-
low you to save in running costs and re-
duce harmful emissions.
GENERAL CONSIDERATIONS
Vehicle maintenance
The conditions of the vehicle are an im-
portant factor which affects fuel consump-
tion as well as driving tranquillity and the
life of the car itself. For this reason, care
should be given to maintenance, having
the checks and adjustments given in the
scheduled maintenance programme car-
ried out (see ... spark plugs, idle speed,
air/fuel oil filter, timing).
Tyres
Check the tyre pressure at least every 4
weeks: if the pressure is too low, consump-
tion increases as resistance to rolling is
higher. It should also be underlined that in
these conditions, tyre wear increases re-
sulting in poor handling and lower safety. Drive at a moderate
speed when snow chains
have been fitted to the
wheels. Avoid potholes, steps and
pavements, and do not drive for
long stretches on snow-free roads,
otherwise you risk damaging the
tyres, suspension and steering.
Snow chains can be fit-
ted only on wheels with
6.5J x 16” rims and
215/55 R16 tyres or 7.5J x 17”
rims and 225/45 R17 tyres.

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).

207
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.

218
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.
