Buttons for adjusting fan speed
(13, 14 fig. 121 – 7, 8 fig. 122)
Press respectively front control
buttons13or14(fig. 121) and back
control buttons 8or7(fig. 122) to
increase or decrease the fan speed so
to adjust the amount of air let into
the passenger compartment while
keeping the required temperature
constant.
The fan speed is indicated by the
bars which light up on the front dis-
play5(fig. 121) and rear display 3
(fig. 122), when the back control
panel is active. Repeatedly press
button or keep pressed 13(fig. 121)
or8(fig. 122) to switch the fan on
at top speed (all bars on).
Repeatedly press or keep pressed
button14(fig. 121) or 7(fig. 122)
to switch the fan on at minimum
speed (one bar on).When the fan minimum speed is
set up (one bar on), by keeping
pressed for at least two seconds but-
ton14(fig. 121) or 7(fig. 122), the
climate control system is deactivated
and all the fan bars on the display
turn off; OFFmessage is displayed.
The fan speed can be adjusted
manually through both the front
control panel and the rear control
panel, but it is the same one for the
whole passenger compartment.
IMPORTANTPress the AUTO
button to restore air distribution
control after a manual setting.AUTO buttons
(automatic operation)
(1, 9 fig. 121 - 5 fig. 122)
Press the AUTObutton on the dri-
ver side and/or front/back-seat pas-
senger side: the system will automat-
ically control the air amount and
distribution pattern in the related
passenger compartment areas and
will cancel all the previously made
settings. This condition is marked by
the message FULL AUTOon the
system front and rear display,
besides the leds on the air distribu-
tion buttons turning off.
If one of the functions automatical-
ly controlled by the system (air recir-
culation, air distribution, fan speed
or air conditioner compressor deacti-
vation) is manually adjusted, the
messageFULLon the display turns
off to indicate that the system is no
longer controlling the functions inde-
pendently (apart from temperature
control that is always automatic).

158
IMPORTANTAir at a temperature
lower than that of the outside air
cannot be let in to the passenger
compartment when the compressor
is off. Furthermore, in particular
environmental conditions, the win-
dows could mist up fast because the
air is no longer dehumidified.
The setting will be stored when the
engine is stopped. Either press √
button again or press the AUTObut-
ton to reset automatic control of the
compressor (in the latter case, the
manual settings will be cancelled).
The led on the √button will go out. IMPORTANTThe air recircula-
tion function will allow, according to
the system operation (i.e. heating or
cooling) to reach the required condi-
tions faster. We recommend not
turning on this function on rainy
and/or cold days as this will consid-
erably increase window misting,
especially if the climate control sys-
tem is off.
In particular climate
conditions (e.g. low out-
side temperature or high
humidity) and with the inside air
recirculation automatic control
on, windows could start misting
up. In this case, press the air
recirculation button and set it to
forced open position (both button
leds off), and increase air flow to
the windscreen, if required.Climate control system
compressor off button (7 fig. 121)
Press the √button, when the but-
ton led is on, to switch the air condi-
tioner compressor off. The led will
go off. By pressing again the button
when the led is off, the system auto-
matic control of the compressor acti-
vation is restored; this situation is
indicated by button led lighting up.
When the air conditioner compres-
sor is off, if the system is no longer
able to keep the requested tempera-
ture, the message FULL AUTOon
the display turns off and the system
deactivates air recirculation to pre-
vent window misting up. Instead, if
the system is still able to maintain
the requested temperature, the mes-
sageFULLon the display will stay
on.

159
The air let into the passenger com-
partment cannot be cooled when the
compressor is off. Consequently:
– if the outside temperature is
lower than the set temperature, the
system works normally and can
reach and maintain the set tempera-
ture also when the compressor is off;
– if the outside temperature is
higher than the set temperature, the
system cannot reach the required
temperature. This will be signalled
by flashing the external temperature
value on the display.
When the compressor is off, it is
possible to reset manually the fan
speed; on the contrary, when the
compressor is on and the engine is
running, manual ventilation cannot
be lower than the bar indicated on
the display. Button for fast windscreen
demisting/defrosting (15 fig. 121)
Press this button: the climate con-
trol system will automatically switch
on all the functions required for fast
windscreen and side window demist-
ing/defrosting, that is:
– climate control system compres-
sor on;
– air recirculation off (if on);
– maximum air temperature (HI)
on both displays;
– fan speed according to engine
coolant temperature in order to limit
letting cold air into the passenger
compartment for demisting the win-
dows;
– air flow directed to the wind-
screen and front side window vents;
– heated rear window, external
rearview mirror and windscreen noz-
zle resistances on.The fast windscreen demisting/
defrosting function stays on for
approx. 3 minutes after the engine
coolant temperature exceeds 50 °C
(petrol versions) or 35 °C (diesel
versions).
When the fast demisting/defrosting
function is on, the led on the related
button and that on the heated rear
window button are lighted, while
both leds on the air recirculation
button and that on button √turn
off. Message FULL AUTOon the
display will turn off.
Only the fan speed can be adjusted
and the heated rear window can be
switched off when the fast demist-
ing/defrosting function is on.
Press the fast demisting/defrosting
button again or air recirculation
button or compressor off button to
switch the fast demisting/defrosting
function off and reset the previous
system operation conditions as well
as the last set function.

FUEL CUT-OFF SWITCH AND
CIRCUIT BREAKER
The car is fitted with two safety
switches that come into operation in
the case of an accident to block fuel
supply and power, thereby stopping
the engine and the car electric utili-
ties. It also prevents fuel spilling if the
lines are broken in the accident or
sparks and flashover due to electric
component damages.
After the crash, remember to turn
the ignition key to STOPto prevent
the battery running down.

173
If, after an accident, you
can smell petrol or see
that the fuel feed system is
leaking, do not reset the switches
to avoid the risk of fire.Mechanical connections
of outside handles are
active only if the doors
are locked. In case the driver has
activated the central door locking
from the inside and, after an
accident, the inertial switch was
not able to activate the automatic
door unlocking as a result of bat-
tery loss or damage, it will not be
possible to reach the passenger
compartment from the outside.Anyway, door opening
from the outside depends
on their conditions after
the accident: if a door is distorted
it might be impossible to open it
even if it is unlocked. In this case
try to open the other car doors.
Before resetting the fuel
cut-off switch, carefully
check for any fuel leaks or
damages to the car electric devices
(e.g.: headlights).
fig. 129
L0A0273b
If, after an accident, you cannot see
any fuel leaks or damages to the car
electric devices (e.g.: headlights) and
the car is in a fit state to continue its
journey, reset the fuel cut-off switch
and the circuit breaker according to
the following instructions.
Door unlocking in case of
accident
In case of accident with activation of
the inertial switch as a consequence,
door locks are automatically unlocked
to let rescuers reach the passenger
compartment from the outside.Resetting the fuel cut-off switch

move cover B.
4) Press button A(fig. 132) to reset
the circuit breaker.Initialising the control units of
the door locks, air conditioner
and ESP system
After resetting the circuit breaker, to
restore correct door locking, air con-
ditioning and ESP system, perform
the following operations:
1) Close the doors and the tailgate,
fit the key into the lock of one of the
front doors and perform a door cen-
tralised opening/closing cycle.
2) Start the engine and turn on the
compressor of the conditioner, setting
a lower temperature value than that
of the environment and check
whether the led on the disconnection
push button of the conditioner com-
pressoròis lit.
3) Turn the steering wheel one
fourth turn at least (the car can be at
standstill but the engine shall be run-
ning) and start running the car for a
few metres in a straight line until the
ESP warning light
áis off.
