STEERING WHEEL
LEVERSThe devices and services controlled by the
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)
When the pointer on the knurled ring is op-
posite the symbol O, the external lights are
switched off.
Sidelights (fig. 69)
The sidelights are switched on by turning
the knurled ring from Oto

warning light on the instrument
panel will come on at the same time.
Dipped-beam headlights (fig. 70)
These are switched on by turning the
knurled ring from
6
to 2
.Main-beam headlights (fig. 71)
When the knurled ring is in the
2
posi-
tion, the headlights can be changed from
dipped-beam to main-beam by pushing the
lever towards the dashboard (stable posi-
tion). The
1
warning light will come on
on the instrument panel.
To return from main-beam to dipped-beam,
once again pull the lever towards the steer-
ing wheel and then release.

Flashing (fig. 72)
The headlights are flashed by pulling the
lever towards the steering wheel (unstable
position) regardless of the position of the
knurled ring. The
1
warning light on the
instrument panel will come on at the same
time.
WARNINGOnly the main-beam lights
are flashed. To avoid penalties, follow lo-
cal regulations.Direction indicators (fig. 73)
Moving the lever to the stable position will:
up - engage the right-hand direction indi-
cators.
down - engage the left-hand direction in-
dicators.
One of the warning lights (
R
or
E) will
come on on the instrument panel at the
same time.
The lever is returned to its home position
automatically and the indicators are
switched off when the steering wheel is
straightened.WARNINGIf you wish to signal a rapid
change of direction involving only a mini-
mum movement of the steering wheel, the
lever can be moved up or down without
clicking (unstable position). When released
the lever will return to its home position.

RIGHT-HAND LEVERThe right-hand lever is used to operate the
windscreen wiper and windscreen washer.
The control used to activate the windscreen
washers also activates the headlights wash-
ers, if fitted.Windscreen wiper - windscreen
washer (fig. 74-75)
The lever can be moved to five different
positions corresponding to:
A- Stationary (off).
B- Intermittent.
With the lever in position (B), turning the
ring (F) four possible intermittent speeds
are obtained:
■
= intermittent slow.
■■
= intermittent medium.
■■■
= intermittent medium-fast.
■■■■
= intermittent fast.C- Continuous, slow.
D- Continuous, fast.
E- Fast, temporary (unstable position).
Operation in position (E) is limited to the
time the lever is held in this position. When
the lever is released, it returns to position
(A) automatically stopping the wiper.

HEADLIGHT CORRECTOR (fig. 121)
If the car is fitted with xenon headlights,
beam aiming is electronic and therefore con-
trol (A) on the mask near the steering col-
umn is not present.
The headlights should be aimed correctly
depending on the vehicle load.
The control (A) on the plate at the side of
the steering column can be moved to four
positions corresponding to the vehicle loads
given below:
position 0: 1 or 2 people occupying front
seats, full fuel tank, on-board equipment pre-
sent;
position 1: 5 people on-board;fig. 121

HAND BRAKE
(fig. 122)
The hand brake lever is located between
the two front seats.
To operate the brake when the vehicle is
“stationary”, pull the lever (A) upwards un-
til the required braking action is obtained.
When the ignition key is in the MARpo-
sition, the
x
warning light will come on on
the instrument panel.

BONNETThe lever used to open the bonnet is lo-
cated under the left end of the dashboard.
To open:
– Pull the lever (A-fig. 166) until the
bonnet clicks open.
CAUTIONS FOR CARRYING
LUGGAGETravelling at night with a load in the boot
it is necessary to adjust the height of the low
beam headlights (see next paragraph
“Headlights” in this chapter). For correct use
of the aiming device, also make sure that
the load does not exceed the values given
in the same paragraph.
fig. 166
A0B0049m
Do not load the luggage
compartment above the
permitted maximum (see “Tech-
nical specifications”). Also make
sure that the objects contained in
the boot are well secured to pre-
vent them from being thrown for-
ward causing harm to the passen-
gers in the event of sharp braking.
WARNING
A heavy load that has not
been secured may cause
serious harm to passengers in the
event of an accident.
WARNING
When wanting to carry a
spare can of petrol, this
must be done in compliance with
the law, only using a certified can,
appropriately fastened to the load
restraint eyelets. Even so, the risk
of fire is increased.
WARNING
Only with the car sta-
tionary.

HEADLIGHTSLIGHT BEAM AIMINGWARNINGThe adjustment of the head-
lights is vital to your safety and comfort and
to that of other road users. The adjustment
of the headlights is also governed by precise
regulations. To guarantee both to yourself
and to the other drivers the best visibility
conditions when travelling with the head-
lights on, the vehicle must have its head-
lights properly adjusted.
Contact Alfa Romeo Authorized Services to
have the headlights correctly adjusted.
IMPORTANTOn the inside surface of
the headlight there could appear a slight
coat of fogging; this does not show a defect,
since it is a natural occurrence due to low
temperature and to the degree of humidity
in the air; it will soon disappear as soon as
the lights are turned on. The presence of
drops inside the headlight shows water seep-
age: refer to the Alfa Romeo Dealership.
ROOF RACK
PROVISIONThe car is set for mounting special roof
racks.
Roof racks, especially designed for this car,
must be fastened to pins (A-fig. 168) set
under the packing, as shown in the figure.
Strictly comply with the
regulations in force con-
cerning the maximum over-
all dimensions.
fig. 168

After a few kilometres,
check that the fastening
screws are firmly tightened.
WARNING
Distribute the load evenly
and when driving, bear in
mind the increased sensitivity to
side wind.

COMPENSATION FOR TILT(fig. 169)
If the car is fitted with xenon headlights,
beam aiming is electronic and therefore con-
trol (A) on the mask near the steering col-
umn is not present.
When the vehicle is loaded, the beam from
the headlights is raised due to the back-
wards tilt of the vehicle.
In this case the headlights must be ad-
justed using control (A) located on the plate
at the side of the steering column.This control has four positions corre-
sponding to various vehicle loads given be-
low:
– position 0: 1 or 2 people occupying
front seats, full fuel tank, on-board equip-
ment present;
– position 1: 5 people on-board;
– position 2: 5 people on-board, luggage
compartment full (50 kg approximately);
– position 3: driver and 300 kg in lug-
gage compartment.fig. 169

Check the positioning of
the headlight beams every
time you change the load to be car-
ried.
WARNING
ADJUSTING THE FRONT
FOGLIGHTS (for versions/markets where
applicable)
To adjust the height of the beam of the
front foglights, act on adjusting screw (A-
fig. 170).fig. 170

Contact Alfa Romeo Au-
thorized Services to have
the headlights correctly ad-
justed.

The electromechanical system to auto-
matically keep constant trim makes the
headlight tilt compensating device unnec-
essary.
The xenon lamps have very long life which
makes possible fault very unlikely.
If necessary, have the sys-
tem checked and repairs (if
any) made only by Alfa Romeo Au-
thorized Services.
WARNING
GAS DISCHARGE HEADLIGHTS(optional for versions/markets
where applicable)
The gas (xenon) discharge headlights op-
erate with a voltaic arc, in an ambient sat-
urated with pressure xenon, instead of the
glow filament.
The resulting illumination is sensibly higher
to that of conventional lamps, both for light
quality (clearer light) and for the width and
positioning of the illuminated area.
The advantages of better illumination can
be perceived (due to less eyesight fatigue
and greater orientation capacity for the dri-
ver, which in turn means higher driving
safety) especially in case of bad weather,
fog and/or insufficient road signs, thanks
to the better illumination of the side parts
of the visual field, normally obscured.The large increase of the side part illumi-
nation increases driving safety since it allows
the driver to better see the other users on
the edge of the road (pedestrians, cyclists
and bikers).
The triggering of the voltaic arc requires a
very high voltage, while subsequent power
supply can take place at a low voltage.
The headlights achieve their top luminos-
ity approx. 15 seconds after they are
switched on.
The intense light produced by this type of
headlights requires the use of an automatic
system to keep headlight trim constant and
avoid dazzling the vehicles coming from the
opposite direction in case of braking, accel-
eration or when carrying loads.

DIPPED BEAM HEADLIGHT
AIMING FOR LEFT-HAND/
RIGHT-HAND DRIVING(only for versions with gas
discharge headlights)
As regards cars equipped with gas dis-
charge headlights (xenon lamps)(optional
for versions/markets where applicable) with
very great lighting power, when passing
from a country with right-hand driving to one
with left-hand driving, or vice versa, it is nec-
essary to modify the orientation of the
dipped beam headlights, to optimize the il-
lumination of the road edge and avoid daz-
zling the vehicles coming from the opposite
direction.
To have this operation
carried out, contact Alfa
Romeo Authorized Ser-
vices.
When you go back to your
country of origin, remem-
ber to have the dipped beam head-
light orientation modified again.
WARNING
In the event of a failure, though being un-
able to rely on the antilock effect, there is
absolutely no adverse effect on vehicle brak-
ing performance in terms of braking capac-
ity.
If you have never used a car with ABS be-
fore, you are advised to learn how to use
it with a few preliminary trials on a slippery
surface, naturally under safety conditions
and fully adhering to the Highway Code of
the country concerned. You are also advised
to carefully read the following information.
The advantage of the ABS compared with
the conventional system is that it makes it
possible to maintain maximum vehicle han-
dling performance also in the case of hard
braking under grip limit conditions, avoiding
wheel lock.
Do not however expect the braking dis-
tance always to be reduced with the ABS
system: for example, on soft surfaces such
as gravel or fresh snow on slippery surfaces,
the distance might increase.
ABSThe car is fitted with an ABS system which
prevents wheel lock when braking, better
exploits wheel grip and keeps the vehicle
controllable within the limits of the available
grip also during emergency braking.
The driver can feel that the ABS is opera-
tional by a light pulsing of the brake pedal,
accompanied by noise.
This should not interpreted as malfunc-
tioning of the brakes, but it is the signal to
the driver that the ABS system is working:
it is the warning that the car is travelling at
the limit of grip an that, therefore, it is nec-
essary to adapt the speed to the type of road
on which you are travelling.
The ABS system is an additional part of the
basic braking system; in the event of a fault
it is disabled, leaving the braking system
in the same conditions as a car without ABS.
