LIMITATIONS
With the vehicle in "TURTLE" mode,
climate control limitations are
automatically introduced to preserve
the range.
WARNING
5) The air conditioning system uses R134a
or R1234yf refrigerant compatible with the
regulations in force in the countries where
the vehicle is sold. When charging, only
use the gas indicated on the dedicated
plate in the engine compartment . The
use of other coolants affects the efficiency
and condition of the system. The lubricant
used for the compressor is also strictly

PARKING HEATER

(for versions/markets, where provided)
PROGRAMMABLE
VERSION
The additional heater is located on the
roof or in the glove compartment of the
cab, where provided. It is completely
independent of the operation of the
engine for:
heat 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. 120 for turning the
heater on manually or for programming
the time 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.
The heater can turn off spontaneously
due to misfiring after start-up or
because the flame goes out during
operation. In this case, carry out the
turning off procedure and try to turn the
