IGNITION DEVICE THE SWITCH
(fig. 12)
The key can be moved to one of four po-
sitions:
– STOP: engine switched off, key can be
removed, engine lock engaged, steering lock
engaged, all services excluded apart from
those powered directly (e.g. hazard warn-
ing lights).
– MAR: drive position. The engine lock
is deactivated and all electrical devices are
powered.
WARNINGNever leave the key in this
position when the engine is stationary.– AV V: unstable position for starting the
engine.
WARNINGIf the engine does not start,
return the ignition key to the STOPposi-
tion and repeat the sequence.
The ignition block is fitted with a safety de-
vice preventing it from being moved to the
AV Vposition when the engine is already
running.
– PARK: engine switched off, key can
be removed, engine lock engaged, steer-
ing lock engaged, sidelights automatically
switched on.
WARNINGTo turn the key to the
PARKposition, button (A) located on the
switch should be pressed first.If the ignition device is
tampered with (for exam-
ple during an attempted
break-in) have it checked over by
Alfa Romeo Authorized Services,
before travelling again.

PRE-TENSIONING DEVICESTo increase the efficiency of the front seat
belts, Alfa 156 is fitted with pre-tension-
ing devices.
These devices “feel” that the car is being
subject to a violent impact by way of a sen-
sor rewind the seat belts a few centimetres.
In this way they ensure that the seat belt
adheres to the wearer before the restraining
action begins.
The seat belt locks to indicate that the de-
vice has intervened; the seat belt cannot be
drawn back up even when guiding it man-
ually.
WARNINGThe pretensioner will give
maximum protection when the seat belt ad-
heres snugly to wearer’s chest and hips.
Front seat pretensioners activate only if
front seat belts are properly fitted into buck-
les. A small amount of smoke may be pro-
duced. This smoke is in no way toxic and
presents no fire hazard.
The emergency tensioning retractor needs
no maintenance or lubrication. Any modifi-
cation to its original features will nullify the
retractor’s effectiveness. If, due to unusual
natural events (floods, high waves, etc.),
the device has been affected by water and
mud, it must be replaced.Operations involving
banging, vibrations or
heating (above 100°C for
a maximum of 6 hours) in the area
of the pretensioners may damage
or trigger off the device. Vibrations
from rough road surfaces or acci-
dental jolting caused by mounting
pavements etc. do not have any ef-
fect on the pretensioner. If, how-
ever, you need assistance, go to
Alfa Romeo Authorized Services.
The pretensioner can only
be used once. After a col-
lision that has triggered it, have it
replaced at Alfa Romeo Authorized
Service. The validity of the device
is written on the plate located on
the front left door near the lock.
Contact Alfa Romeo Authorized
Services to have pretensioner re-
placed as this date approaches.
WARNING
After adjustment, always
check that the slider (B) is
anchored in one of the positions
provided. To do this, with the but-
ton (A-fig. 50) or (A-fig. 51) re-
leased, exert a further pressure to
allow the anchor device to catch if
release did not take place at one of
the preset positions.
WARNING
Make the height adjust-
ment when the car is sta-
tionary.

GENERAL INSTRUCTIONS FOR
THE USE OF THE SEAT BELTSAll the occupants of the car are obliged to
respect the local traffic laws regarding the
wearing of seat belts.
Always fasten the seat belts before starting.
fig. 52
A0B0004m
Never disassemble or
tamper with the preten-
sioner components. All interven-
tions must be carried out by qual-
ified and authorised personnel.
Always contact Alfa Romeo Au-
thorized Services.
WARNING
To ensure the highest de-
gree of protection, you are
recommended to keep the seat
backrest in the straightest position
possible, and the belt adhering well
to the chest and pelvis.
Seat belt should always be worn
in both the front and rear positions!
Travelling without seat belt in-
creases the risk of serious injury or
death in the case of accident.
WARNING
The seat belt must not be
twisted and should cling
tightly to the body. The upper part
must pass over the shoulder and di-
agonally across the chest. The
lower part must rest across the
pelvis and not across the stomach
to eliminate the risk of sliding for-
wards (fig. 52). Do not use devices
(clips, stoppers, etc.) which keep
the belts away from the body.
WARNING
Under no circumstances should
the components of the seat
belts and pretensioner be tampered
with or removed. Any operation should
be carried out by qualified and autho-
rised personnel. Always contact an
Alfa Romeo Authorized Service.
WARNING

GETTING TO KNOW YOUR CAR45
The bags inflate instantaneously, setting
themselves between the body of the front
passengers and the car door. The bags de-
flate immediately afterwards.
In the event of minor side crashes (for
which the restraining action of the seat belts
is sufficient), the air bags are not deployed.
Also in this case it is of vital importance to
wear the seat belts since in case of side
crash they guarantee proper positioning of
the occupant and prevent the occupant to
be pitched out of the car in case of violent
crashes.
Therefore the side air bags do not replace
but are complementary to the use of belts,
which you are recommended to always
wear, as specified by law in Europe and most
non-European countries.
Operation of the side air bags and window
bags is not disabled by the front air bag de-
activation switch, as described in the previ-
ous paragraphs.WARNINGThe front and/or side air
bags may be activated if the car is subjected
to heavy shocks or accidents that involve the
underbody area, such as for example violent
bumps against steps, pavements or fixed ob-
stacles on the ground, falling into big holes
or bumpy roads.WARNINGThe triggering of air bags re-
leases a small amount of powder. This pow-
der is not harmful and does not indicate a
start of fire; also the surfaces of the de-
ployed bag and the car interior may be cov-
ered with dusty residue: this may irritate the
skin and eyes. In the event of exposure,
wash with neutral soap and water. WARNINGIn the event of side crash,
you can obtain the best protection by the
system keeping a correct position on the
seat, thus allowing correct window bag un-
folding.
The airbag system has a validity of 14
years for the pyrotechnic charge and 10
years for the coil contact (see the plate lo-
cated on the front left door near the lock).
Contact Alfa Romeo Authorized Services
for replacement as these dates approach.
Never rest head, arms and
elbows on the door, on the
windows and in the window bag
area to prevent possible injuries
during the inflation phase.
WARNING
Never lean head, arms and
elbows out of the window.
WARNING

GETTING TO KNOW YOUR CAR46
WARNINGIf an accident has triggered
the air bag, Alfa Romeo Authorized Services
must be contacted to have the devices ac-
tivated replaced and to have the whole sys-
tem checked.
All operations involving checking, repair-
ing and replacing components concerning
the Air bag must be carried out by Alfa
Romeo Authorized Services.
If the car is to be demolished, Alfa Romeo
Authorized Services should be contacted be-
forehand to have the system deactivated.
If the car changes ownership, the new
owner must be informed of the instructions
for use and of the above warnings and be
given this “Owner’s Manual”.
WARNINGThe triggering of the pre-
tensioners, front air bags and side bags is
decided by the electronic control unit in a
differentiated manner depending on the type
of crash. The failure to trigger one or more
of them does not necessarily indicate a sys-
tem malfunction.
GENERAL CAUTIONS
If the
¬
warning light does
not turn on when turning the
ignition key to MAR or if it stays on
when travelling, this could indicate a
failure in safety retaining systems; un-
der this condition air bags or preten-
sioners could not trigger in the event
of collision or, in a restricted number
of cases, they could trigger acciden-
tally. Stop the car and contact Alfa
Romeo Authorized Services to have
the system checked immediately.WARNING
Do not cover the back rest
of front seats with trims or
covers there are not set for the use
of side bags.
WARNING
Never travel with objects
on your lap, in front of the
chest or with a pipe, pencil, etc. be-
tween your lips. Serious injury may
result in the case of the air bag be-
ing triggered.
WARNING
Always keep your hands
on the steering wheel rim
when driving, so that if the Air bag
is triggered, it can inflate without
meeting any obstacles. Do not
drive with the body bent forwards,
keep the seat back rest in the erect
position and lean your back well
against it.
WARNING
If the car has been stolen
or an attempt to steal it
has been made, if it has been sub-
jected to vandals or floods, have
the Air bag system checked by Alfa
Romeo Authorized Services.
WARNING
Please don’t apply stickers
or other objects to the
steering wheel, to the air-bag
cover on the passenger's side or on
the side roof lining to the uphol-
stery on the roof side. Don’t place
objects on the dashboard passen-
ger’s side (such as mobile phones)
because they could tamper with the
correct opening of the passenger’s
air-bag and than cause serious in-
juries to the vehicle occupants.

levers on the steering wheel can only be ac-
tivated when the ignition key is in the MAR
position.LEFT-HAND LEVERThe left-hand lever controls the external
lights except the foglamps and the rear fog-
light.
When the external lights are switched on
the various controls located on the dash-
board are illuminated.
The sidelights will come on if the ignition
key is in the PARKposition, regardless of
the position of the knurled ring.Lights switched off (fig. 68)

TO INCREASE THE MEMORISED
SPEEDThe speed memorised can be increased
in two ways:
1)pressing the accelerator and then mem-
orising the new speed reached (turning the
ring (B) for more than three seconds);
or
2)momentaneously turning the ring (B)
to (+): each pulse of the ring will correspond
to a slight increase in speed (about 1.5
km/h) while pressing continuously will cor-
respond to a continuous speed increase. Re-
leasing the ring (B) the new speed will be
memorised automatically.TO REDUCE THE MEMORISED
SPEEDThe speed memorised can be reduced in
two ways:
1)disengaging the device (for instance
pressing the brake pedal) and then memo-
rising the new speed (turning the ring (B)
to (+) for at least three seconds);
2)keeping the ring pressed (B) at (–)
until reaching the new speed which will be
memorised automatically.
RESETTING THE MEMORISED
SPEEDThe memorised speed is automatically re-
set turning off the engine or moving the ring
(A) to OFF.
When travelling with the
cruise control on, do not
move the gearshift lever to neutral.
WARNING
The cruise control may only
be engaged at speeds be-
tween 30 and 190 km/h.
WARNING
It is advisable to engage
the cruise control only
when the conditions of the traffic
or road so permit under completely
safe conditions: i.e.: straight and
dry roads, dual carriageways or
motorways, flowing traffic and
smooth road surface. Do not en-
gage the device in town or in
heavy traffic conditions.
WARNING
If the device is faulty or
not working, turn the ring
(A) to OFF and contact Alfa Romeo
Authorized Services after checking
that the protection fuse is intact.
WARNING

GETTING TO KNOW YOUR CAR62
REV COUNTERThe rev. counter shows engine rpm. The
needle pointed to the danger area (red) in-
dicates excessive high engine speed. Do not
drive for long periods with the needle in this
area.
WARNINGThe electronic injection con-
trol system gradually shuts off the flow of
fuel when the engine is “over-revving” re-
sulting in a gradual loss of engine power.
The rev counter may, when the engine is
idling, indicate gradual or sudden increase
of engine revs as the case may be; such be-
haviour is normal and must not be inter-
preted as a faulty condition as it occurs dur-
ing normal operation, for instance when
climate control or electric fan are switched
on. In particular, slow revs variation helps
keep the battery charged.
FUEL GAUGE AND RESERVE
WARNING LIGHTThis shows the amount of fuel left in the
fuel tank.
This warning light
ç
comes on to indicate
that approximately 7 litres of fuel are left in
the tank.
WARNINGUnder certain conditions
(heavy slopes, for instance), the reading on
the gauge may differ from the actual
amount of fuel in the tank and changes in
level may be indicated late.
This condition falls within the operation log-
ics of the electronic control circuit to avoid
highly unstable readings due to swaying of
the fuel when travelling.
WARNINGRefuelling shall always be
performed with engine off and ignition key
to STOP. If the engine is off but the key
is to MAR, a wrong fuel level could tem-
porarily be indicated. This is due to the in-
ternal system control logic and cannot be
considered as a system malfunctioning.
ENGINE COOLANT
TEMPERATURE GAUGE AND
MAXIMUM TEMPERATURE
WARNING LIGHTThis shows the temperature of the engine
coolant fluid and begins when the fluid tem-
perature exceeds approx. 50°C.
The pointer should normally be towards
the middle of the scale. If the pointer
reaches the higher temperature values of
the scale (red area), the request for vehi-
cle performance should be decreased.
The illumination of the warning light
ç
(together with the message shown by the
Infocenter display) indicates an excessive
temperature of the engine cooling fluid. In
this case, stop the car and contact Alfa
Romeo Authorized Services.
WARNINGThe temperature of the en-
gine coolant may rise towards the maximum
values (red) when the vehicle is driven at
low speeds, especially when the ambient air
temperature is high. In this case, the vehi-
cle should be stopped and the engine
switched off for a few minutes after which
the journey can be resumed, preferably at
a higher speed.
