During fully automatic operation (FULL AUTO), the word
FULL will disappear if the air distribution and/or flow rate
and/or activation of the compressor and/or recirculation
settings are changed. In this way, the functions will switch
from automatic to manual control until the AUTO button
is pressed again. With one or more functions turned on
manually, the adjustment of the intake air temperature con-
tinues to be managed automatically, except with the com-
pressor switched off: if this is the case, the temperature of
the air introduced into the passenger compartment can-
not be lower than that of the outside air.
CONTROLS
Air temperature adjustment knob (I)
Turn the knob either clockwise or anticlockwise to in-
crease or lower the temperature in the passenger com-
partment.
The temperature set is shown on the display.
Turn the knob either all to the right or all to the left to
the extreme HI or LO position to turn the maximum heat-
ing or maximum cooling functions on:
❒HI Function (maximum heating):
select by turning the temperature knob clockwise over the
maximum value (32 °C). USING THE CLIMATE CONTROL SYSTEM
The system can be started in different ways, but it is ad-
visable to start by pressing the AUTO button and then
turning the knob to set the temperature required on the
display. The system will start running automatically in this
way and the set temperature will be reached as quickly
as possible. The system will adjust the temperature, the
quantity and the distribution of the air introduced into the
passenger compartment and will manage the recirculation
function and the air conditioning compressor engagement.
During fully automatic operation the only manual inter-
vention required is the possible activation of the following
functions:
❒Òair recirculation, to keep it always on or off;
❒Zto speed up demisting/defrosting of the front door
window glasses, rear door window glasses and door
mirrors.
During fully automatic system operation, you can change
the set temperatures, air distribution and fan speed at any
time by using the relevant buttons or knobs: the system
will automatically change its settings to adjust to the new
requirements.

WARNING To restore automatic fan speed control af-
ter a manual adjustment, press the AUTO button.
WARNING At high vehicle speeds, the dynamic effect may
increase the air flow rate into the passenger compartment,
which in this case will not directly correspond to the fan
speed bar display.
AUTO button (A)
(automatic operation)
Press AUTO to make the system automatically adjust the
quantity and distribution of the air introduced into the pas-
senger compartment. All previous manual settings will be
cancelled.
The message FULL AUTO appears on the front display.
By manually adjusting at least one of the functions auto-
matically managed by the system (air recirculation, air dis-
tribution, fan speed or air conditioning compressor on/off),
the word FULL will disappear from the display, indicating
that the system is no longer automatically controlling all
the functions (the temperature will still be controlled au-
tomatically by the system).▲
˙Air flow distribution split between the windscreen
and front side windows defrosting/demisting diffusers
and the central and side dashboard vents. This dis-
tribution makes it possible to maintain good levels
of comfort and keep the passenger compartment suf-
ficiently cool (summer).

▼Air flow distribution split between the windscreen and
front side windows defrosting/demisting diffusers, the
central and side dashboard vents and the footwell dif-
fusers. This distribution allows good air diffusion and
maintains a good level of comfort both in summer and
winter.
The distribution set is shown by the corresponding LEDs
in the selected buttons coming on.
To restore automatic control of the air distribution after
a manual selection, press the AUTO button.
Fan speed adjustment buttons (H)
Press the outsides of button
Hto increase or decrease the
fan speed and therefore the amount of air admitted into
the passenger compartment, although maintaining the tar-
get temperature.
The fan speed is shown by the bars lit up on the display:
❒Max. fan speed = all bars lit
❒Min. fan speed = one bar lit.
The fan can only be disabled if the climate control com-
pressor has been switched off by pressing button
F-fig. 42.

FUEL CONSUMPTION
The fuel consumption and CO2emission values in the table be-
low are based on tests approved under European directive
2004/3/EC.
The procedures below are followed for measuring consumption
and emissions:
❒urban cycle: cold start and driving style that replicates
the speed and gear changes as per the European di-
rective. There are a series of accelerations, decelera-
tions, constant speeds and stops with engine idling. The
top speed reached during the cycle is 50 km/h and the
average speed is 19 km/h.
❒extra-urban cycle: done after the urban cycle as per
the European directive. The top speed reached dur-
ing the cycle is 120 km/h and the average speed is
63 km/h.
❒combined cycle: determined by an average of the ur-
ban cycle (37 per cent weighting) and extra-urban cy-
cle (63 per cent weighting) consumptions.IMPORTANT
In practice, fuel consumption may be higher than the val-
ues obtained during the approved tests. Here are some of
the major factors that can lead to a difference between
test and real consumption.
1) Vehicle condition: inadequate servicing, use of roof
racks, trailers, heavy loading, high usage of electrical de-
vices and the air conditioning.
2) Driving style: frequent cold starts for short journeys,
poor engine warming technique, gear selection, high
speeds, sudden acceleration and braking.
3) Traffic and road conditions: driving in traffic, steep hills
or winding roads, road surface conditions.
4) Atmospheric conditions: intemperate weather, wind,
rain, snow, high altitude.
5) Proportion of use in towns and cities, in the country
and on motorways.

9. Air conditioning leads to higher fuel consumption (on
average up to +30%). If the temperature outside is not
too extreme, try and use the air vents.
Driving style
1. After starting the engineyou should drive away im-
mediately and slowly, avoiding high revs. Do not warm
up the engine at low or high revs when the vehicle is
stationary; this causes the engine to warm up more
slowly, thereby increasing fuel consumption, emissions
and mechanical component wear.
2. Avoid pointless actions such as revving up when at
traffic lights or before stopping the engine. The latter
action, like double-declutching, is unnecessary and caus-
es increased fuel consumption and pollution.
3.Gear selection: select a high gear as soon as possible
(taking into account normal engine operation and traf-
fic conditions) without pushing the engine to high revs
during the intermediate gears. Using low gears at high
revs to get excellent acceleration increases fuel con-
sumption, harmful emissions and engine wear. PRACTICAL ADVICE FOR REDUCING FUEL
CONSUMPTION AND HARMFUL EMISSIONS
Vehicle condition
1. Have checks and servicingcarried out in accordance
with the “Scheduled servicing plan”.
2. Check tyre pressure regularly, at least once every four
weeks. Excessively low pressures will increase con-
sumption because rolling resistance will be higher. In
these conditions, the tyre will wear and performance
will decay faster.
3. Use snow tyresonly when the weather conditions
make them absolutely necessary. They increase con-
sumption and noise.
4. Do not travel with a heavy load: the weight of the
vehicle (especially when driving in town) and its trim
greatly affect fuel consumption and stability.
5. Remove roof racks or ski racksafter use. These ac-
cessories reduce the vehicle’s aerodynamic penetra-
tion and have a negative effect on fuel consumption.
6. It is better to use a trailer to transport particularly bulky
objects.
7. Use the vehicle’s air vents if possible: travelling with the
windows open impairs aerodynamics.
8. Use electrical devices only for the amount of time
needed. The heated rear window, auxiliary headlights,
windscreen wipers and fan heater use up a consider-
able amount of current, causing increased fuel con-
sumption (up to +25% in the urban cycle).
