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
A0B0142m
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
A0B0240m
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
A0B0239m
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.

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.
