START&STOP
Manual climate control system
If the Start&Stop function is activated (engine off
when the car speed is zero), the system keeps the air
flow selected by the user.
In these conditions, the passenger compartment
cooling and heating cannot be guaranteed, as the
compressor stops with the engine coolant pump.
The Start&Stop function can be deactivated, to
enhance the operation of the climate control system,
by pressing the dedicated button on the dashboard.
ADDITIONAL ELECTRIC HEATER
(for versions/markets, where provided)
The additional electric heater ensures more rapid
passenger compartment heating.
It activates in cold weather conditions, if the
following conditions are verified:
❒outside temperature low;
❒engine coolant temperature low;
❒engine on;
❒fan speed set at least to 1
stspeed;
❒knob A turned completely clockwise to red
section.The heater is switched off when at least one of the
conditions above is no longer verified.
NoteThe power of the electric heater is modulated
according to the battery voltage.
SYSTEM MAINTENANCE
In winter, the climate control system must be turned
on at least once a month for about 10 minutes.
Have the system inspected at a Fiat Dealership
before the summer.
The system uses R134a coolant which
does not pollute the environment in the
event of accidental leakage. Under no
circumstances use R12 fluid, which is
incompatible with the components of the system.

CLIMATE CONTROL SYSTEM
COMPRESSOR
Press button D to activate/deactivate the
compressor (activation is indicated by the LED on
the button switching on).
The system remembers that the compressor has
been switched off, even after the engine has stopped.
When the compressor is switched off the system
deactivates air recirculation to prevent the windows
from misting up. In this case, if the system is capable
of maintaining the required temperature, the AUTO
LED does not switch off.
The temperatures will instead flash for a few seconds
and the AUTO LED will switch off if the required
temperature cannot be maintained.
To restore automatic control of compressor
engagement, press button C again or press the
AUTO button.
With compressor off:
❒if the outside temperature is higher than the set
one, the climate control system will not be able
to satisfy the request. The temperature values will
then flash on the display for a few seconds to
indicate this;
❒the fan speed can be reset manually.
With the compressor on and the engine running,
manual ventilation cannot be lower than the
minimum speed (only one LED lit).IMPORTANT With the compressor off, air cannot
be introduced to the passenger compartment with a
temperature lower than the outside temperature.
Moreover, under certain environmental conditions,
windows could mist rapidly since the air is not
dehumidified.
RAPID WINDOW DEMISTING/
DEFROSTING (MAX-DEF function)
Press the
button to activate (LED on button on)
the windscreen and side window demisting/
defrosting function.
The climate control system carries out the following
operations:
❒switches on the air conditioning compressor when
environmental conditions are suitable;
❒switches air recirculation off;
❒sets maximum air temperature (HI) in both zones;
❒sets fan speed according to the engine coolant
temperature;
❒directs air flow to windscreen and front side
windows diffusers;
❒activates the heated rear window;
❒activates the heated windscreen (for versions/
markets, where provided);
❒displays the fan speed (LED G lit).
IMPORTANT The MAX-DEF function remains on for
about 3 minutes from when the engine coolant
reaches the appropriate temperature.

When the function is activated, the LED on the
AUTO button switches off. With the function
activated the only possible manual adjustments are
adjusting the fan speed and turning the heated rear
window off.
When the B, C, or AUTO buttons are pressed, the
climate control system will deactivate the MAX-DEF
function.
Selecting the footwell/windscreen or only windscreen
distribution activates the climate control system
compressor (LED on A/C button on) and the air
recirculation is set to "outside air" intake (LED on
button off ).
This logic guarantees optimum visibility at the
windows. It is, however, always possible to manage
air recirculation and the climate control system
compressor manually.
HEATED REAR WINDOW
DEMISTING/DEFROSTING
Press the

SWITCHING OFF THE CLIMATE
CONTROL SYSTEM
Press button
.
With climate control system off:
❒air recirculation is on, thus isolating the passenger
compartment from the outside;
❒the compressor is off;
❒the fan is off;
❒the heated rear window can be activated/
deactivated.IMPORTANT The climate control system control
unit stores the temperatures set before the system
was switched off and restores them when any button
of the system is pressed (except for button D).
To restart the climate control system in fully
automatic mode press the AUTO button.
START&STOP
Automatic dual zone climate control system
The automatic dual zone climate control system
manages the Start&Stop function (engine off when
car speed is zero) to ensure adequate comfort inside
the car.
The Start&Stop function is disabled until a suitable
comfort level in the passenger compartment is
ensured; thus the engine does not turn off during
these temporary stages, even if car speed is zero.
When the Start&Stop function is active (engine off at
zero car speed), the climate control system will
request the reactivation of the engine if the inside
temperature conditions rapidly deteriorate or if
maximum cooling ("LO") or quick demisting
(MAX-DEF) are requested.
With the Start&Stop function active (engine off at
zero car speed), air flow is reduced in order to
maintain comfort conditions inside the passenger
compartment as long as possible when the system is
in AUTO mode (LED on button on).

When a low air flow is selected, the climate control
system control unit always activates the Start&Stop
function.
The climate control system control unit attempts to
manage the "discomfort" caused by the engine
stopping (deactivation of compressor and engine
coolant pump) as best it can but the operation of the
climate control system can be enhanced through
the deactivation of the Start&Stop function by
pressing the
button on the dashboard control trim
(see contents of "Start&Stop system" paragraph in
this chapter).
NoteIn particularly severe climate conditions it is
recommended to limit the use of the Start&Stop
function to prevent the compressor from
continuously switching on and off, with consequent
rapid misting of the windows and accumulation of
humidity with unpleasant smells in the passenger
compartment.
NoteWhen the Start&Stop function is on (engine
off and vehicle speed zero), the automatic
recirculation management is turned off always taking
air in from outside, to reduce the probability of
window misting up (as the compressor is off ).ADDITIONAL HEATER
(for versions/markets, where provided)
This allows the passenger compartment to be heated
more quickly in cold weather conditions.
The heater switches off automatically when the
required comfort conditions are achieved.
The additional heater activates automatically
depending on the environmental conditions and with
engine started.
IMPORTANT The heater only operates if the outside
temperature and engine coolant temperature are
low. The heater will not activate if the battery
voltage is too low.

INCREASING THE STORED SPEED
This can be carried out in two ways:
❒by pressing the accelerator and storing the new
speed reached
or
❒by moving the stalk upwards (+) until the new
speed, which will be stored automatically, is
reached.
Each movement of the stalk corresponds to an
increase in speed of about 1 km/h, while keeping the
stalk held upwards will continuously increase the
speed.
REDUCING THE STORED SPEED
This can be carried out in two ways:
❒by deactivating the device and then storing the
new speed
or
❒by moving the lever downwards (–) until the new
speed, which will automatically remain stored, is
reached.
Each movement of the lever corresponds to a
reduction in speed of about 1 km/h, while keeping
the stalk held downwards will decrease the speed
continuously.DEACTIVATING THE DEVICE
The device can be deactivated by the driver in the
following ways:
❒turning ring nut A toO;
❒by stopping the engine
❒by pressing the brake pedal, the clutch or the
accelerator; in this last case the system is not
completely deactivated but gives priority to the
acceleration request. The device still remains
active, without the need to press the CANC RES
button to return to the previous condition once
acceleration is concluded.
