- 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.). 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 recirculation, air
flow, air capacity. This operation inhibits the
incipient misting sensor signal until the
AUTObutton is pressed again or the next
time the ignition key is turned toMAR.
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 spirit).
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.
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: 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.

HOW TO USE THE AUTOMATIC
TWO-ZONE CLIMATE CONTROL
SYSTEM
(fig. 100)
IMPORTANTThe knob rings do not
have a mechanical stopper therefore, once
the maximum or minimum value has been
reached, they are free to turn in both direc-
tions.
The system can be started in different
ways, but it is advisable to set the temper-
atures required on the displays; then press
the (13)
AUTObutton.
This way the system will start working
completely automatically to reach the tem-
peratures set as quickly as possible and then
maintain them.
During completely automatic system op-
eration, the temperatures set can be
changed at any time; the system will auto-
matically change its settings to adjust to the
new requirements.IMPORTANTTo be able to be accept-
ed by the system, the difference in the tem-
perature between the driver’s and passen-
ger’s side must be within a range of 7°C.
It is possible to personalise the choices
made automatically by the system inter-
vening manually on the following controls:
- fan speed adjustment knob (4)
- air distribution selection buttons (10)
- inside air re-circulation on/off button (8)v
- climate control on enable button (14)
√.
Manually selecting one or more of these
functions turns off the right led on the but-
ton (13)
AUTO.With one or more functions engaged man-
ually, the adjustment of the temperature of
the air admitted to the passenger compart-
ment continues to be controlled automati-
cally by the system (left led on button 13
AUTOon) except with the climate control
compressor off.
In fact, in this condition the air admitted
to the passenger compartment cannot have
a lower temperature than the outside air;
this condition is indicated by the turning off
of the two leds on button (13)

AIR DISTRIBUTION SELECTION
BUTTONS
(fig. 107)
Pressing one or more buttons (10) it is
possible to manually choose one of the 5
possible air distributions to the passenger
compartment:
REFlow of air to the dashboard centre
and side outlets and rear outlet.E
R
ZESplitting of the air flow between the
vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets and the rear outlet (coolest
air). The air flow distribution is par-
ticularly useful in spring and autumn,
when the sun is shining.
ZAir flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural tenden-
cy of heat to spread upwards, this
type of distribution allows heating of
the passenger compartment in the
shortest time, also giving a prompt
feeling of warmth to the coldest parts
of the body.
A0A0208b
Q
ZSplitting of the air flow between the
windscreen and side window defrost-
ing/demisting vents and the lower
part the of the vehicle. This type of air
distribution allows satisfactory heat-
ing of the passenger compartment
while preventing misting of the win-
dows.
QAir flow to the windscreen and front
side window vents to demist or de-
frost them.IMPORTANTPressing one of these but-
tons turns on (led on button itself on)
or off (led on button off) the associ-
ated functions if the combination cho-
sen is among the 5 possible ones; if
not it only activates the main function
of the button pressed, without the
possibility of turning off with anoth-
er press (at least in one distribution
the air flow should be spread in the
passenger compartment).

The gearbox can work in two operating
modes:
– the first is semiautomatic(then called
MANUAL), in which the driver directly re-
quests gearshifting through the lever on the
centre console or pressing the buttons at the
steering wheel;
– the second is automatic, calledCITY
(mode selectable with the specific button
B-fig. 119, the CITYsign appears on the
displayfig. 121), in which the system de-
cides directly when to shift gear.SELESPEED
TRANSMISSION
(on request for versions/markets
where applicable)
IMPORTANTTo be able to use the Se-
lespeed correctly, this chapter should be read
in full to understand the correct, permissible
operations to be carried out right from the
start.
This device comprises a conventional me-
chanical gearbox to which an electronical-
ly-operated electro-hydraulic device has been
added which automatically controls the
clutch and gear engagement.
The clutch pedal has been eliminated and
the vehicle moves off using only the accel-
erator pedal.Gearshifting takes place through the con-
trol lever (A-fig. 119) which is of the
floating type with a “single central stable
position”. Using the lever it is possible to re-
quest an increase/decrease of the gear ra-
tio engaged and/or reverse gear engage-
ment (R) or neutral (N).
There are also two buttons on the steering
wheel spokes (fig. 120) through which,
only with the car on the move (with speed
above 0.5 km/h), it is possible to shift gear
up or down.

SEMIAUTOMATIC OPERATION
(MANUAL)
In the MANUAL operating mode, the dis-
play shows the gear engaged.
In this operating mode, the decision to
change gear is left to the driver who decides
the most appropriate moment.The requests to change gear may take
place through:
– the control lever on the centre console
(A-fig. 126);
– the buttons on the steering wheel
(fig. 127), which can be operated only
when the car speed exceeds 0.5 km/h.
TheMANUALoperating mode is set
when, with the CITYmode selected, the
CITYbutton(A-fig. 128) is pressed
again, excluding the previously selected
mode.When changing gear it is not necessary
to release the accelerator pedal because the
Selespeed system directly controls the en-
gine in such a way as to:
– reduce and then increase engine torque;
– adapt the engine speed to the latest
gear engaged.
When downshifting, the engine is accel-
erated automatically to bring it to the speed
necessary with the new gear ratio.
The neutral command (N) is accepted un-
til the vehicle speed exceeds 20 km/h.
The reverse gear engagement command
(R) is accepted only if the vehicle is sta-
tionary.
