PROCEDURE FOR PETROL
ENGINESWARNINGIt is important not to press
the accelerator until the engine has started.
1) Make sure the handbrake is engaged.
2)Move the gear lever to neutral.
3)Fully depress the clutch pedal so that
the starter motor is not forced to crank the
toothed wheels of the gearbox.
4)Ensure that the systems and electrical
devices, especially if they absorb high quan-
tities of energy (e.g. heated rear wind-
screen) are switched off.
5)Turn the ignition to the AV Vposition
and release it as soon as the engine starts.
6)If the engine does not start, return the
key to the STOPposition and repeat the
operation.
WARNINGIf it is difficult to start the en-
gine do not insist with extended attempts
which may damage the catalyzer but con-
tact Alfa Romeo Authorized Services. The ignition switch is fitted with a safety
device which obliges the driver to return the
ignition key to the STOPposition before re-
peating the starting operation if the engine
does not start immediately.
Similarly, when the engine is running, the
device prevents the key being moved from
the MARto the AV Vposition.
STARTING
THE ENGINEWARNINGThe car is fitted with an elec-
tronic engine lock device. If the engine fails
to start see “Alfa Romeo CODE system”.

In addition to the notes
and specifications given be-
low we recommend that,
during the initial period, you do not
drive to full vehicle performance
(for example excessive accelera-
tion, long journeys at top speed,
hard braking, etc.).
To avoid useless con-
sumption of power and
possible draining the bat-
tery, never leave the ignition key
in the MAR position when the en-
gine is not running.
Running the engine in con-
fined areas is extremely
dangerous. The engine consumes
oxygen and produces carbon
monoxide which is a highly toxic
and lethal gas.

WARNINGOn the 2.0 JTS version,
keep the brake pedal pressed when starting
the engine. As the brake pedal stiffens if it
is pressed repeatedly with the engine off. In
this situation, to allow the engine to be
started, it is necessary to increase the pres-
sure exerted on the pedal itself.PROCEDURE FOR JTD VERSIONS1)Make sure the handbrake is engaged.
2)Move the gearshift lever to neutral.
3)Turn the ignition key to the MARpo-
sition. The warning light
m
on the instru-
ment cluster will turn on.
4)Wait for the
m
warning light to go
off, which will depend on how warm the en-
gine is. With the engine very hot the warn-
ing light may stay on for such a short time
that it is not noticed.
5)Fully depress the clutch pedal.
6)Turn the ignition key to AV Vas soon
as the
m
warning light goes off. Waiting
too long would make the glow plug heating
work pointless.WARNINGThe electric devices that ab-
sorb much energy (air conditioner,
rearscreen heating, etc.) are disengaged au-
tomatically during engine starting.
If the engine does not start at the first at-
tempt, move the ignition key back to the
STOPposition before repeating starting.
If starting is difficult (with the Alfa Romeo
CODE system efficient), do not insist with
prolonged attempts.
Only use an auxiliary battery if it is noted
that the cause is due to low charge of the
car’s battery. Never use a battery charger to
start the engine (see “If the battery is flat”
in the chapter “In an emergency”).
WARMING THE ENGINE– Drive off slowly, at medium revs with-
out accelerating abruptly.
– Do not drive at full performance for the
initial kilometers of the journey, Wait until
the engine coolant temperature is between
50 and 60°C.SWITCHING OFF– Release the accelerator pedal and wait
until the engine reaches idle speed.
– Turn the ignition key to the STOPpo-
sition and switch off the engine.
WARNINGAfter a taxing drive it is bet-
ter to allow the engine to “catch its breath”
before turning it off by letting it idle to al-
low the temperature in the engine com-
partment to fall.

CORRECT USE OF THE CAR
191
EMERGENCY STARTINGIf the Alfa Romeo CODE system does not
recognise the code transmitted by the igni-
tion key (Alfa Romeo CODE
Y
warning
light on the instrument cluster on glowing
steadily) emergency starting may be carried
out using the code of the CODE card.
For the correct procedure see the chapter
“In an emergency”.
PARKINGWhen the vehicle is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is facing up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a half if the handbrake
slips. Starting by pushing, tow-
ing or running downhill
must absolutely be
avoided. These manoeuvres may
cause fuel to flow into the catalyst
and damage it irreparably.
To avoid useless con-
sumption of power and
possible draining the bat-
tery, never leave the ignition key
in the MAR position when the en-
gine is not running.
For vehicles equipped
with turbocharger in par-
ticular and for other vehi-
cles in general, revving the engine
before switching off should be
avoided.
Revving the engine serves no pur-
pose and consumes fuel for no rea-
son. It may also cause damage to
the bearings on the rotor of the
turbocharger.
WARNINGIf the engine turns off with
the car on the move, the next time it is
started, the Alfa Romeo CODE warning lightY
may turn on. In this case, check that
switching off and starting the engine again
with the car stationary, the warning light
stays off. If not, contact Alfa Romeo Au-
thorized Services.
Remember that the servo-
brake and power steering
are not activated until the engine
is started, therefore considerably
greater effort is required on the
brake pedal and steering wheel.
WARNING
Never leave children unat-
tended in the car. Always
remove the key from the ignition
when leaving the car and take it
with you.

SAFE DRIVINGIn designing your Alfa 156, Alfa
Romeo has worked thoroughly to achieve a
vehicle able to offer top levels of safety to
its passengers. However, the behaviour of
the driver is still a decisive factor for road
safety.
Below you will find a few simple rules for
travelling safely under different conditions.
You are certainly familiar with many of them
but it is still helpful to read them all care-
fully.BEFORE DRIVING OFF– Make sure the lights and headlights are
working properly.
– Adjust the seat, steering wheel and
rearview mirrors, in order to obtain a correct
position for driving.
– Adjust the seat back upright and keep
your head as close as possible to the head
restraint.– Carefully adjust the headrests so that
the head and not the neck rests on them.
Check that nothing (mats, etc.) can get un-
der the foot pedals.
– Make sure that any child restraint sys-
tem (seats, cradles, etc.) are correctly fas-
tened on the rear seat.
– Place any objects in the boot with care
to prevent abrupt braking from throwing
them forwards.
– Avoid heavy meals before a journey. A
light meal will help to keep reflexes ready.
Above all avoid alcohol.
Routinely remember to check:
– tyre pressure and conditions;
– engine oil level;
– engine coolant level and system condi-
tions;
– brake fluid level;
– power steering oil level;
– windscreen washer fluid level.
WHEN TRAVELLING– The first rule for safe driving is care.
– Care also means being able to predict
the actions of other road users.
– Strictly respect the traffic regulations in
all countries, especially the speed limits.
– Ensure that both yourself and your pas-
sengers are wearing their seat belts, that
children are carried with the appropriate
seats and that any animals are in appropri-
ate compartments.
– Long distances should be trackled in
good health.
Driving under the influence
of drugs and/or some
medicines is highly dangerous for
oneself and for others.
WARNING

CORRECT USE OF THE CAR
193
– Do not drive for long periods without a
break. During breaks get out of the vehicle
and move around a bit to shake off the
drowsiness.
– Make sure the air in the passenger com-
partment is changed constantly.
– Never coast the vehicle downhill with
the engine switched off as this eliminates
the engine braking and power steering ef-
fect thus requiring a greater effort on the
pedal and steering wheel.
NIGHT DRIVINGHere are some suggestions for night dri-
ving.
– Drive with particular care: night driving
involves a greater degree of concentration.
– Reduce speed, especially on unlit roads.
– At the first signs of drowsiness stop the
car: continuing the journey is dangerous for
yourself and others. Continue driving only
after sufficient rest.
– Maintain a greater distance from the ve-
hicle in front than in the day: it is more dif-
ficult to judge the speed of the vehicle when
only the lights can be seen.
– Ensure that the headlights are correctly
aligned: if they are too low, visibility is re-
duced and eyesight is tired. If they are too
high they may cause disturbance to other
road users.
– Use the main beams only outside built-
up areas and only when you are certain that
other drivers are not disturbed by their use.
– When meeting vehicles coming in the
opposite direction, switch off the main
beams and drive with the dipped-beam
headlights on.
– Keep headlights and lights clean.
– Outside built-up areas take care of ani-
mal crossings.
Always fasten the front
and rear seat belts includ-
ing those of any child’s seat. Trav-
elling without seat belts increases
the risks of serious injury or even
death in the event of an accident.
WARNING
Take care when fitting ad-
ditional spoilers, alloy
wheels and wheel caps: they might
reduce ventilation of the brakes,
thus their efficiency, during abrupt
and repeated braking, or long
downhill slopes.
WARNING
Never drive with objects
on the floor in front of the
driver’s seat: they might get stuck
under the pedals making it impos-
sible to accelerate or brake.
WARNING
Make sure any mats are
appropriate in size: even a
slight inconvenience to the braking
system may require a higher pedal
stroke than normal.
WARNING
Water, ice and salt on the
roads may deposit on the
brake discs, reducing the effec-
tiveness of the brakes the first
time they are used.
WARNING

CORRECT USE OF THE CAR
194
DRIVING IN THE RAINRain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– If it is raining particularly heavily, visi-
bility is also reduced. In these cases, switch
on the dipped headlights even if it is still day-
light so you can be seen more easily.
– Do not drive through puddles at speed
and hold on tightly to the wheel if you do: a
puddle taken at high speed might cause you
to lose control of the car (“aquaplaning”).
– Position the ventilation controls for
demisting (see chapter “Getting to know
your car”), to prevent visibility from wors-
ening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN THE FOG– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main beam headlights.
WARNINGOn stretches of road with
good visibility, switch off your rear foglights;
the brightness of these lights could annoy
the people travelling in the cars behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped beam headlights. Ry-
thmically sound the horn if you note another
car coming.
MOUNTAIN DRIVING– When driving downhill, use the engine
braking by engaging a low gear, to prevent
the brakes from overheating.
– Never coast downhill with the engine off
or in neutral and especially not with the ig-
nition key removed.
– Drive at moderate speed and avoid “cut-
ting” corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the
other vehicle to pass in safety.

CORRECT USE OF THE CAR
195
DRIVING ON SNOW AND ICEHere are few suggestions for driving in
these conditions:
– Keep your speed down.
– On a snowy road, fit winter tyres or
snow chains; see the related paragraphs in
this section.
– Use exhaust brake where possible and
avoid abrupt braking.
– Avoid abrupt acceleration and changes
of direction.
– During cold weather even apparently dry
roads may be covered with occasional
patches of ice. Pay great attention therefore
when driving on roads which are in the
shade, or where rocks or trees line the road
and on which ice may persist.
– Keep further back from the vehicle in
front.
DRIVING WITH ABSThe ABS is a part of the braking system
which essentially offers two advantages:
1)It prevents wheel lock-up and conse-
quent skidding in emergency stops, partic-
ularly when the road does not offer much
grip;
2)It makes it possible to brake and steer
at the same time so you can avoid unex-
pected obstacles and direct the car where
you want while braking. The extent to which
this can be done will depend on the physi-
cal limits of the tyre’s sideways grip.
To make the most of the ABS:
– In emergency braking or when grip is
low, a slight pulsing can be felt on the brake
pedal: this means that the ABS has come
into action. Do not release the pedal, but
continue pressing it to give continuity to the
braking action.
– The ABS prevents the wheels from lock-
ing but it does not increase the physical lim-
its of grip between the asphalt and the road.
Therefore, also with a car fitted with ABS,
keep within a safety distance from the ve-
hicle in front and limit speed when ap-
proaching bends.
The ABS serves to increase car controlla-
bilty not to go faster.
REDUCING RUNNING
COSTS AND
ENVIRONMENT
POLLUTIONSome suggestions which may help you to
keep the running costs of your vehicle down
and lower the amount of toxic emissions re-
leased into the atmosphere are given below.GENERAL CONSIDERATIONSVehicle maintenance
The overalll state of the vehicle is an im-
portant factor which has a marked influence
over fuel consumption and driving comfort
and on the life span of your vehicle. For this
reason care should be taken to maintain
your vehicle by carrying out the necessary
checks and regulations in accordance with
specifications given in the “Scheduled Main-
tenance Programme” (see sections... spark
plugs, air cleaner, timing).

CORRECT USE OF THE CAR
196
Tyres
Tyres should be checked at least every four
4 weeks: if the pressure is too low, fuel con-
sumption increases as the resistance to the
rolling movement of the tyre is higher. In
this state, tyre wear is increased
and vehicle handling suffers which will af-
fect safety.
Unnecessary loads
Do not travel with too much luggage stowed
in the boot. The weight of the vehicle (es-
pecially when driving in town) and its trim
greatly affects consumption and stability.
Luggage/ski rack
Remove luggage or ski racks from the roof
of the vehicle as soon as they are no longer
needed. These accessories reduce the aero-
dynamic penetration of the vehicle and will
increase consumption. When transporting
particularly large objects, use a trailer where
possible.Electrical devices
Use the electric devices for the necessary
time only. The heated rear window, supple-
mentary lights, windscreen wipers, heating
system blower require large amounts of en-
ergy and, increasing the request for power
also increases fuel consumption (up to
+25% when driving in built-up areas).
Air conditioner
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside the
vehicle permits it, use the air vents where
possible.
Spoilers
The use of aerodynamic optional extras
which are not certified for the specific use
on the vehicle, may reduce the aerodynamic
penetration of the vehicle and increase con-
sumption.
STYLE OF DRIVINGStarting
Do not warm the engine when the vehicle
is stationary or at high or low revs: in this
way the engine will warm up gradually in-
creasing consumption and emissions. You
should drive off slowly straight away avoid-
ing high revs so that the engine will warm
up more quickly.
Unnecessary actions
Avoid revving the engine when stopped at
traffic lights or before switching off the en-
gine and avoid doubling the clutch as these
actions have no purpose on modern vehicles
and serve only to increase consumption and
pollution.
Gear selection
As soon as the traffic and road conditions
allow it, shift to a higher gear. Using a lower
gear to liven up acceleration greatly in-
creases consumption. In the same way, im-
proper use of the higher gears will increase
consumption, emissions and wear and tear
on the engine.

CORRECT USE OF THE CAR
197
Top speeds
Fuel consumption increases considerably
as speed increases. For example, when ac-
celerating from 90 to 120 kph, fuel con-
sumption increases by about +30%. Your
speed should be kept as even as possible
and superfluous braking and acceleration
avoided as this increases both consumption
and emissions. A “soft” way of driving
should be adopted by attempting to antici-
pate manoeuvres to avoid imminent danger
and to keep a safe distance from the vehi-
cle in front in order to avoid braking sharply.
Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: acceleration should be gradual and
should not exceed the maximum torque.
CONDITIONS OF USECold starting
Short journeys and frequent cold starting
will not enable the engine to reach optimal
running temperature. It follows therefore
that consumption will be higher (from +15%
to +30% in built-up areas) as will the pro-
duction of toxic emissions.
Traffic and road conditions
Heavy traffic and higher consumption are
synonymous; for example, when driving
slowly with frequent use of lower gears or
in large towns where there are numerous
traffic lights.
Winding roads, mountain roads and
bumpy roads also have a negative effect on
consumption.
Enforced halts
During prolonged hold-ups (traffic lights,
level crossings) the engine should be
switched off.
ECONOMY AND
ENVIRONMENT-
FRIENDLY DRIVINGEnvironment protection is one of the prin-
ciples that guided the development of your
Alfa 156.
It is not merely by chance that its antipol-
lution devices obtain results far beyond those
specified by current regulations.
The environment, however, still needs the
utmost care from all of us.
By following few simple rules it is possible
to avoid damage to the environment and
very often at the same time to limit fuel con-
sumption. On this subject we are giving
some helpful suggestions to be added to
those marked with the
#, in various points
of this manual.
Kindly read them all carefully.

CORRECT USE OF THE CAR
198
PROTECTING EMISSION
REDUCING DEVICESCorrect operation of the antipollution de-
vices not only guarantees respect for the en-
vironment but also influences car perfor-
mance. Keeping these devices in good con-
dition is therefore the first rule for both en-
vironment-friendly and economy driving.
The first precaution is to closely follow the
“Scheduled Maintenance Programme ”. For
petrol engines only use unleaded petrol (95
RON) (specification EN228), for diesel en-
gines only use fuel oil for motor vehicles
(specification EN590).
If difficulty with starting is experienced do
not insist with extended attempts. Especially
avoid bump, tow or coast starts: these may
all damage the catalyst. Only use an auxil-
iary battery to start the car in an emergency.If the engine is “not running smoothly”
when the vehicle is travelling, reduce the re-
quest for performance to a minimum and
contact Alfa Romeo Authorized Services as
soon as possible.
When the fuel reserve warning light comes
on fill up as soon as possible. A low fuel level
may cause an irregular supply to the engine
with inevitable increase of the exhaust gas
temperature; this would result in serious
damage to the catalyst.
Never run the engine, even as a test, with
one or more spark plugs disconnected. Do
not warm the engine at idle speed before
moving off, unless the outside temperature
is very low and, in this case too, for no more
than 30 seconds.
Do not install other heat
guards and do not remove
the existing ones on the catalyst
and exhaust pipe.
WARNING
Do not spray anything on
the catalyst, lambda sen-
sor and exhaust pipe.
WARNING
The failure to follow these
rules may cause a fire
hazard.
WARNING
During normal service the
catalyst reaches high tem-
peratures. Do not therefore park
the car over inflammable materials
(grass, dry leaves, pine needles,
etc.): fire hazard.
WARNING
