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.

IMPORTANT The programmed
switching on time can be altered or
cancelled by following the instructions
given previously.
Operation duration
setting
Hold the button pressed. At the same
time press button 3 or 8.
The time and warning light 7 are
displayed.
Hold button 4 pressed again. At the
same time press button 3 or 8.
The preset activation duration is
displayed and warning light 9 or 2
flashes.
Set the activation duration with button
3or8.
The set activation duration is stored as
soon as the text in the display
disappears, or pressing button 4.
Switching the heating
system off
Deactivation of the system, depending
on the type of activation (automatic
or manual), may be:
❒automaticwhen the programmed
duration is over; when the set time
is over, the display switches off.❒manualpressing the “immediate
heating” button on the timer again
(flame button 6).
In both cases, the heating warning light,
the display lighting and the passenger
compartment heater fan go off and
burning stops.
The fluid circulation pump continues to
work for around two minutes to
dissipate as much heat as possible; the
heater can be turned back on during
this stage.
22)
IMPORTANT The parking heater goes
off when battery voltage is low to allow
the vehicle to be started.
IMPORTANT Before turning on the
device, ensure that the fuel level is
above the reserve. Otherwise the
device could lock and require
the assistance of a Fiat Dealership.
❒Always turn off the heater when
refuelling and near service stations to
avoid the risk of explosion or fire
hazards.
❒Do not park the vehicle on
inflammable material such as paper,
grass or dry leaves: fire hazard!❒The temperature near the heater
should not exceed 120°C (e.g. during
oven painting in a body shop). The
electronic control unit components
may be damaged at higher
temperatures.
❒Whilst the heater is operating with the
engine switched off, it absorbs
energy from the battery; the engine
should therefore be left running
for a while to make sure that the
battery is properly recharged.
❒To check the coolant level, follow the
instructions in the "Vehicle
maintenance" chapter, "Engine
coolant system fluid" paragraph. The
water in the heating circuit must
contain a minimum percentage of
10% antifreeze.
❒For maintenance and repairs, consult
only a Fiat Dealership and use only
original parts.
MAINTENANCE
Have the additional heater checked
regularly at a Fiat Dealership (and
always at the start of every winter). This
will guarantee safe and economic
operation of the heater as well as a long
duration.
