SPEEDOMETER
(SPEED INDICATOR)
The gauge (A-fig. 72) indicates the car
speed.
ODOMETER
Odometer display (B-fig. 72) with dou-
ble meter (total and trip) and headlamp po-
sition display.
The display shows:
– the mileage on the first line (6 figures)
– the trip meter on the second line (4 fig-
ures)
– aside the position of the headlight aim-
ing device.To reset the trip meter, keep button (A-
fig. 73) 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.REV COUNTER (fig. 74)
The danger zone (red, or white on certain
versions) indicates excessive high engine
speed. Do not drive for long periods with the
pointer 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 climate control system or the fan.
In particular a slow change in the speed pre-
serves the battery charge.

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
Pressing button (4-fig. 93)vacti-
vates inside air re-circulation and the led
next to the button lights up.
In this case the climate control system
directly treats the air contained in the pas-
senger compartment, the fan is on.
To switch the air re-circulation feature off
and withdraw air from outside, press the
button again. The inside air recirculation
system makes it possible
to reach the required
“heating” or “cooling” conditions
faster. It is however inadvisable to
use it on rainy/cold days as it
would considerably increase the
possibility of the windows misting
inside, especially if the manual cli-
mate control system is off.
It is advisable to turn on
the inside air recirculation
system
vin queues or
tunnels to avoid admitting pollut-
ed air from outside. The prolonged
use of this function should howev-
er be avoided, especially with sev-
eral persons on board, to avoid the
possibility of the windows misting
inside.
REARSCREEN HEATING
ON/OFFBUTTON
Pressing button (5-fig. 93)(turns
on demisting/defrosting of the rearscreen,
and if present, the door mirrors heating
coils; simultaneously the led next to the but-
ton turns on. This function is timed and
switches off automatically after 20 minutes.
To turn off earlier, press the button again.
IMPORTANTThe system automatical-
ly turns on rearscreen heating if the tem-
perature is below 3°C.
IMPORTANTDo not apply stickers on
the inside of the rearscreen over the heat-
ing filaments to avoid damage which
might cause it to stop working properly.
When cleaning the inside
of the rearscreen, take
care not to damage the
heating filaments.

DEMISTING
AND/OR DEFROSTING THE
WINDSCREEN AND FRONT
SIDE WINDOWS, REARSCREEN
AND WING MIRRORS
(MAX-DEF FUNCTION)(fig. 94)
Proceed as follows:
- turn the ring of the air distribution knob
(3) to the
-symbol.
The climate control activates all the func-
tions necessary to quicken demisting/
defrosting of the windscreen and side win-
dows with timing (switching off automati-
cally after 3 minutes), as follows:
- switches off air re-circulation, if engaged;
- sets the maximum air temperature;
- operates the fan at a predefined speed;
- directs the flow of air towards the wind-
screen and front side window vents;
- turns on rearscreen heating and, if pre-
sent, the wing mirror coils. When the max demisting/defrosting func-
tion is on, the led next to the rearscreen
heating button (5)
-will turn on.
IMPORTANTIf the engine is not hot
enough, the function does not immediate-
ly engage the pre-established fan speed,
to restrict the inlet of air to the passenger
compartment that is not warm enough to
demist the windows.
After demisting/defrosting, simply use
the controls to maintain the optimum con-
ditions of vision and comfort.
IMPORTANTThe hotter the engine
the more effective defrosting will be. IMPORTANTIn cases of heavy damp
and/or rain and/or big differences in tem-
perature between inside the car and out-
side, it is advisable to proceed as follows
to demist the windows:
- air re-circulation off, led next to button
(4)
voff;
- pointer of knob (2) at fan second speed
at least;
- pointer of knob (3) on symbol
≤with
the possibility of passing to position
yif
more misting is noted;
To defrost/demist the rearscreen, press
button (5)
(, led next to button on.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
(for versions/markets where applicable)
To start the system (fig. 96):
- 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 side
with a maximum difference of 7°C
between the driver’s side and the passen-
ger’s side.
IMPORTANTThe climate control com-
pressor can only work with the engine run-
ning and external temperature not very
low. With low external tem-
perature the climate con-
trol compressor is unable
to work. It is therefore inadvisable
to use the inside air recirculation
function vwith low outside tem-
perature as windows may mist
over quickly.
For further details about the system and
how to make the best use of it, read the
instructions given in pages that follow.
A0A0203b

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.

IMPORTANTThe demisting procedire
is enabled each time the ignition key is
turned to MARor pressing the button
AUTO. When this procedure is working it
can be turned off pressing one of the fol-
lowing buttons : compressor, air recircula-
tion, air distribution, air flow. This opera-
tion inhibits the incipient misting sensor
signal until the button
AUTOis 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
recirculation to lessen the harmful effects
of polluted air in cities, queues, tunnels
and operation of the windscreen washer
(with the typical smell of spirits).
IMPORTANT The function of the
antipollution sensor is subordinate to safe-
ty conditions; therefore disabling the cli-
mate control compressor or with low exter-
nal temperature, the sensor is disabled. In
any case, the sensor can be re-enabled
pressing the recirculation button
vuntil
taking it to the automatic mode. To ensure correct opera-
tion of the incipient mist-
ing sensor, stickers must
not be applied (road licence holder,
time card etc.). Care should also be
given to cleaning the windscreen
and the actual sensor, avoiding the
accumulation of dust and other sub-
stances.
GENERAL
The car is fitted with a two-zone climate
control system, controlled by an electronic
control unit which makes it possible to
separately adjust the air temperature on
the driver’s side and on the passenger’s
side. To obtain optimum temperature con-
trol in the two areas of the passenger
compartment, the system has an outside
sensor, a passenger compartment sensor
and a two-zone sun ray sensor.
On some versions the system is integrat-
ed with an incipient misting sensor
installed behind the inside rear-view mir-
ror, capable of “controlling” a predefined
area of the windscreen inner surface
which can automatically act on the system
to prevent or reduce misting through a
series of operations such as: opening air
re-circulation, enabling the compressor, air
flow to the windscreen, fan speed suffi-
cient for demisting; in the case of heavy
misting, enabling the
MAXDEFfunction.
