INSTRUMENTS
SPEEDOMETER (fig. 103)
The speedometer shows the car
speed expressed in kilometres per
hour (km/h) and starts signalling
the speed when the car speed
exceeds approx. 4 km/h (see the
indications given in paragraph “At
the filling station").REV COUNTER (fig. 104)
If the needle is in the hazard sector
(the section with red lines) it shows
that the engine is over-revving. Do
not travel with the needle in this sec-
tor.
When the engine is idling, the rev
counter may show a gradual or sud-
den increase in engine speed,
according to the case. This is normal
and indicates the operation of the
climate control compressor or fans,
etc. In particular, a gradual varia-
tion in engine revolution speed safe-
guards battery charge.IMPORTANTThe hazard sectors
can present different widths and dif-
ferent full scale values according to
the various car versions.
IMPORTANTThe electronic injec-
tion control system will progressive-
ly cut off the flow of fuel when the
engine is over-revving and the
engine will consequently lose power.

HEADLIGHTS
GAS-DISCHARGE (BI-XENO)
MAIN BEAM / DIPPED BEAM
HEADLIGHTS AND DYNAMIC
BEAM ADJUSTMENT DEVICE
These headlights, called Bi-Xeno,
use a lamp with a xenon-filled bulb,
both for the dipped beam and the
main beam headlights.
The main characteristics of this
type of headlights are:
– higher brilliancy
– higher light beam width and
adjustability
– lower consumption under work-
ing conditions
– longer bulb life.Each headlight is equipped with an
electronic control unit used to con-
trol supply voltage. Due to high bril-
liancy, bi-Xeno headlights require
the adoption of a dynamic beam
adjustment control system.
This system is controlled by an
electronic control unit operating at
two levels:
– constant headlight beam realign-
ment as a function of the car load
– dynamic headlight beam align-
ment to compensate car pitching
when running.Operation
Light is projected onto the road by
means of a spherical glass lens with
a large surface (70 mm diameter).
A deflector lifts and lowers, so that
light distribution is different for
both the main beam and dipped
beam headlights. The deflector is
electrically operated and the
mechanical lifting/lowering opera-
tion is performed real-time when
lights are switched.
The xenon lamp consists of a bulb
containing low-pressure xenon and
two electrodes.
To obtain light emission, an elec-
tric arc must be triggered between
the two electrodes and maintained.
Each headlight is equipped with a
control unit which:
– checks the voltage/current value
under working operation
– triggers the arc to the electrodes
and cause salt evaporation at
switching on.

RIMS AND TYRES
Alloy rims or steel.
Tubeless tyres with radial carcass.
The homologated tyres are listed in
the log book.
IMPORTANTIn the event of dis-
crepancies between information
given in the Owner Handbook and
that shown in the Log Book, refer to
the latter one.
To ensure safety of the car in
movement, it must be fitted with
tyres of specified size and of the
same make and type on all wheels.
IMPORTANTDo not use inner
tubes with tubeless tyres. CORRECT TYRE READING
Below, please find the instructions
needed to understand the meaning
of the code stamped on the tyre, as
shown in fig. 6.
The code may be in one of the ways
given in the example.
