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 TYRE READING(fig. 5)
Below are the instructions necessary to
know the meaning of the code stamped on
the tyre.
The code may be like one of the examples
given below.Load index (capacity)
60= 250 kg
61= 257 kg
62= 265 kg
63= 272 kg
64= 280 kg
65= 290 kg
66= 300 kg
67= 307 kg
68= 315 kg
69= 325 kg
70= 335 kg
71= 345 kg
72= 355 kg
73= 365 kg
74= 375 kg
75= 387 kg
76= 400 kg
77= 412 kg
78= 425 kg
79= 437 kg
80= 450 kg
81= 462 kg
82= 475 kg
83= 487 kg84= 500 kg
85= 515 kg
86= 530 kg
87= 545 kg
88= 560 kg
89= 580 kg

96= 710 kg
97= 730 kg
98= 750 kg
99= 775 kg
100= 800 kg
101= 825 kg
102= 850 kg
103= 875 kg
104= 900 kg
105= 925 kg
106= 950 kg
Example:
205/60 R 15 91V
or:
215/45 ZR 17
205= Nominal width (S, distance
in mm between the sides).
60= Percentage height/width (H/S)
ratio.
R= Radial tyre.
ZR= Radial tyre with speed above
240 kph.
15= Rim diameter in inches. (Ø).
91= Load index (capacity), e.g. 91 =
615 kg. Not present in ZR tyres.
V, Z= Maximum speed index. In ZR tyres
the speed index Z is before the R.

CORRECT RIM READINGBelow are the instructions necessary to
know the meaning of the code stamped on
the rim, as shown in fig. 5.
Example:
6.5 J x 16 H2 ET 436.5= rim width in inches (1)
J= rim drop centre outline (side
projection where the tyre bead
rests (2)
16= rim nominal diameter in inches
(corresponds to diameter of the
tyre to be mounted) (3= Ø)
H2= “hump” shape and number (re-
lief on the circumference hold-
ing the Tubeless tyre bead on
the rim)
ET 43= camber angle (distance be-
tween disk/rim line and wheel
rim centre line) Maximum speed index
Q= up to 160 km/h.
R= up to 170 km/h.
S= up to 180 km/h.
T= up to 190 km/h.
