HEADLIGHT ADJUSTMENT
ABROAD
(fig. 135)
The dipped-beam headlights are adjusted
for circulation in the country in which the ve-
hicle is marketed. In countries with opposite
circulation, to avoid glaring oncoming vehi-
cles it is necessary to cover the areas of the
headlight as shown below; this is done us-
ing non-transparent sticker tape.
The illustration refers to passing from right-
hand drive to left-hand drive.
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 high-
er 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 safe-
ty) 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 luminosi-
ty approx. 15 seconds after they are switched
on.
The intense light produced by this type of
headlights requires the use of an automat-
ic system to keep headlight trim constant
and avoid dazzling the vehicles coming from
the opposite direction in case of braking, ac-
celeration or when carrying loads.
The electric mechanical system for auto-
matically keeping the trim constant, makes
unnecessary the device for compensating
the headlight dip and the visual indication
of the position on the display.
Xenon lights have a very long life, there-
fore breakdowns are unlikely.
If necessary, have the sys-
tem checked and repaired
only by Alfa Romeo Authorized
Services.
WARNING

REFUELLING
The antipollution devices
on the car oblige the use of
only four-star unleaded
petrol with an octane number
(R.O.N.) of 95 or over.
Never use leaded petrol,
as this would irreversibly
damage the exhaust gas
catalyst. If leaded fuel is added to
the fuel tank, no matter how small
the quantity, DO NOT START THE
ENGINE. Do not attempt to dilute
the fuel in the tank, completely
drain the fuel circuit and tank.
To prevent accidentally filling with leaded
petrol, the diameter of the fuel tank filler
is of such a size as not to accept the noz-
zle of this type of petrol.
An inefficient catalyst
leads to harmful emission
at the exhaust, thus envi-
ronment pollution.
FUEL CAP (fig. 145)
The fuel cap (A) is key-lockable and has a
catch to prevent misplacing it (B) that fas-
tens it to the flap (C); to gain access to it,
open the flap then use the ignition key to turn
counter-clockwise and remove the cap.
When refuelling, hook the cap to the de-
vice on the inner flap, as illustrated.
IMPORTANTThe sealing of the tank
may cause light pressurising. A little breath-
ing off, while slackening the cap is ab-
solutely normal.

After refuelling, turn the cap clockwise un-
til one or more clicks are heard; then turn
the key clockwise to lock. Close the flap.
IMPORTANTFor your safety, before
starting the engine, also make sure that the
fuel nozzle is correctly inserted in the fuel
distributor.
In the case of need, only
replace the fuel cap with
another genuine one, or the
efficiency of the fuel vapour re-
covery system could be adversely
affected.
Do not go near the fuel
filler with naked flames or
lit cigarettes: danger of fire. Avoid
going too near the fuel filler with
your face, to avoid inhaling harm-
ful vapours.

care not to confuse the var-

SPARK PLUGS
Clean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
maintenance programme. Only use
spark plugs of the specified type:
if the thermal capacity is inade-
quate or if the envisaged life is not
guaranteed inconveniences may en-
sue.
BRAKES
Service brakes: – front
– rear
Parking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.
