MILEAGE RECORDER
Display with double meter (total and trip)
and headlamp position display.
The display shows:
– the mileage on the first line (6 figures)
– the trip meter on the second line (4 fig-
ures)
– the position relating to the headlamp
aiming device.
To reset the trip meter, keep the button
(A-fig. 68) on the plate at the side of the
steering column pressed for a few seconds.IMPORTANTIf the battery is discon-
nected the trip meter reading is not stored. A. Fuel level gauge with reserve warning

gauge with maximum temperature warning

recorder, trip meter and headlamp position

display - F. Rev counter
REV COUNTER
The rev. counter shows engine rpm. The nee-
dle pointed to the danger area (red) indicates
excessive high engine speed. Do not drive for
long periods with the needle in this area.
IMPORTANTThe electronic injection con-
trol system gradually shuts off the flow of fu-
el when the engine is “over-revving” resulting
in a gradual loss of engine power.
When the engine is idling, the rev counter
may indicate a gradual or sudden highering of
the speed, this is normal as it takes place dur-
ing normal operation, for example when en-
gaging the climatecontrol system or the fan.
In particular a slow change in the speed pre-
serves the battery charge.

DIMMER
With this function it is possible to adjust the lighting (dimming/brightening) of the instrument cluster, mileage recorder (total, trip meter),
headlamp aiming display, radio display, radio navigator display and two-zone climate control.
Partial lighting
Keeping the
ãbutton pressed (on the plate at the side of the steering column) for more than 4 seconds the instrument cluster lighting is
turned off with the exception of the speedometer.
Keeping the
âbutton pressed (on the plate at the side of the steering column) for more than 4 seconds the complete instrument cluster
lighting is turned on again.

WARNING
When the outer lights are switched on dimming of the brightness can
be perceived. In the event of any faults, lighting adjustment (rheostat)
is not possible and the display is shown at its maximum brightness.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
To start the system (fig. 76):
- turn the knob rings to set the required
temperatures (driver’s side - passenger’s
side).
- press the
AUTObutton.
IMPORTANTThe climate control sys-
tem makes it possible to personalise the
temperatures required on the two sides with
a maximum difference of 7°C between the
driver’s side and the passenger’s side.
IMPORTANTThe climate control com-
pressor only works with the engine running
and an outside temperature above 4°C.
For further details about the system and
how to make the best use of it, read the
instructions given in the pages that follow.

The coolant used for the
climate control system is
R134a which meets cur-
rent regulations and does not harm
the environment in the event of ac-
cidental spillage.
Absolutely avoid the use of oth-
er fluids which are incompatible
with the system components.
GENERAL
The car is fitted with a two-zone climate
control system, controlled by an electronic
control unit which makes it possible to sep-
arately adjust the air temperature on the dri-
ver’s side and on the passenger’s side. To
obtain optimum temperature control in the
two areas of the passenger compartment,
the system has an outside sensor, a pas-
senger compartment sensor and a two-zone
sun ray sensor.
With an outside tempera-
ture below 4°C the climate
control compressor is unable to
work. It is therefore unadvisable
to use the inside air re-circulation
feature
vwith a low outside
temperature as the windows might
mist over quickly.
WARNING

GETTING TO KNOW YOUR CAR
92
Air quality control is also entrusted to a
combined particle and activated carbon fil-
ter. The climate control system automatically
controls and adjusts the following parame-
ters and functions:
– temperature of the air admitted to the
passenger compartment (for the driver’s and
passenger’s side separately)
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
It is possible to change the setting of the
following functions manually:
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
The control of functions not changed man-
ually remains automatic and in any case the
temperature of the air admitted to the pas-
senger compartment is controlled automati-
cally according to the temperatures set on
the driver’s and passenger’s displays.
IMPORTANTManual selections prevail
over automatic ones and remain in storage
until the user decides to resume automatic
control. The settings selected manually are
stored when the engine is switched off and
resumed the next time it is started. To ensure correct opera-
tion of the incipient mist-
ing sensor, stickers must
not be applied (road licence holder,
time card etc.) in the “control”
area between the sensor and the
windscreen. Care should also be
given to cleaning the windscreen
and the actual sensor, avoiding the
accumulation of dust and other sub-
stances.IMPORTANTThe demisting procedure
is enabled each time the ignition key is
turned to MARor pressing the
AUTObut-
ton. When this procedure is working it can
be turned off pressing one of the following
buttons: compressor, air re-circulation, air
flow, air capacity. This operation inhibits the
incipient misting sensor signal until the
AU-
TObutton is pressed again or the next time
the ignition key is turned to MAR.
On certain versions, the system is inte-
grated by an antipollution sensor capable of
automatically switching on inside air re-cir-
culation to lessen the harmful effects of pol-
luted air in cities, queues, tunnels and op-
eration of the windscreen washer (with the
typical smell of spirits).
IMPORTANTThe function of the an-
tipollution sensor is subordinate to safety
conditions; therefore disabling the climate
control compressor or at an outside tem-
perature below 4°C the sensor is disabled.
The sensor can be re-enabled pressing the
re-circulation button
vuntil taking it to
the automatic mode. On some versions the system is integrat-
ed with an incipient misting sensor installed
behind the inside rear-view mirror, capable
of “controlling” a predefined area of the
windscreen inner surface which can auto-
matically act on the system to prevent or re-
duce misting through a series of operations
such as: opening air re-circulation, enabling
the compressor, air flow to the windscreen,
fan speed sufficient for demisting; in the
case of heavy misting, enabling the
MAX-
DEFfunction.
