IMPORTANT The rapid demisting/
defrosting function for the windows
remains on for about 3 minutes from
when the engine coolant reaches the
appropriate temperature for a rapid
demisting of the windows.
When this function is active, the LED on
the corresponding button and the one
on the heated rear window button
switch on. The message FULL AUTO
goes off on the display.
You can only adjust the fan speed and
switch off the heated rear window
manually when this function is active.
To restore the previous operating
conditions, simply press button B, air
recirculation button G, compressor
button F or AUTO button A.
NoteTo guarantee rapid demisting/
defrosting, if an additional heater/air
conditioner is present (under the front
or rear seat on Panorama and Combi
versions), if activated, deactivate it
using button F (LED off) located
in control panel F fig. 55.Switching the system
OFF (E)
Press button E to switch the climate
control system off. The display will go
out.
The following climate control conditions
will be present when the system is off:
❒display off;
❒temperature setting not displayed;
❒air recirculation on, thereby insulating
the passenger compartment from the
outside (recirculation LED on);
❒climate control compressor off;
❒fan off.
Press the AUTO button to switch the
climate control system back on in
full automatic mode.
ADDITIONAL

KNOW YOUR VEHICLE
INDEPENDENT
ADDITIONAL
HEATER(for versions/markets, where provided)
The vehicle is available, on request,
with two different independent heaters:
one fully automatic, the other which
can be programmed.
AUTOMATIC VERSION
The additional heater is turned on in
automatic mode when the engine
is started and the required outside
temperature and coolant conditions are
present. Deactivation is always
automatic.
21)
IMPORTANT During periods with low
outdoor temperatures when the device
cuts in, check that the fuel level is
always higher than the reserve level.
Otherwise the device could lock and
require the assistance of a Fiat
Dealership.
PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:❒heating the passenger compartment
with the engine off
❒defrosting the windows;
❒heat the engine coolant and then the
engine itself prior to starting.
The system consists of:
❒a diesel burner for heating the water
with an exhaust silencer for the
combustion gases;
❒a metering pump connected to the
reservoir pipes for supplying the
burner;
❒a heat exchanger connected to the
engine cooling system pipes;
❒a control unit connected to the
passenger compartment
heating/ventilation system to allow
automatic operation;
❒an electronic control unit for
controlling and adjusting the built-in
burner;
❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.The additional heater (during winter)
heats, maintains the temperature of and
circulates engine coolant for a set time
period in order to ensure optimum
engine and passenger compartment
conditions at engine start-up.
The heater can operate automatically
when programmed with a digital timer
or manually by pressing the 'immediate
heating' button on the timer.
After heater activation, whether
programmed or manually, the electronic
control unit operates the coolant pump
and turns on the burner in accordance
with pre-set, controlled procedures.
The circulation pump output is also
controlled by the electronic control unit
in order to minimise the initial heating
time.
When the system operates, the control
unit turns on the passenger
compartment heater unit fan at the
second speed.
The thermal power of the boiler is
regulated automatically by the
electronic control unit depending on the
temperature of the engine coolant.
