SUPPLEMENTARY HEATER
INDEPENDENT
(for markets/versions, 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.
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.
The heater burns fuel in the same way
as the engine, though to a lesser extent.
To prevent poisoning and asphyxiation, the
supplementary heater must never be turned on,
even for short periods, in closed environments
such as a garage or workshops without
extraction fans for the exhaust gases.
WARNING
PROGRAMMABLE VERSION
The additional heater operates completely
independently of engine operation and allows the
following:
❒heating the vehicle passenger compartment with the
engine off;
❒defrosting the windows;
❒heating the engine coolant and consequently the
engine itself prior to starting.
The system consists of:
❒a diesel burner to heat the water with an exhaust
silencer for the combustion gases;
❒a metering pump connected to the vehicle tank
pipes, to supply 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 control and operation
of the burner in the heater;
❒a digital timer A-fig. 61 for turning the heater on
manually or programming the time it comes on.

MSR system
(engine braking torque control)
This is an integral part of the ASR system that, in the
event of a sudden gear down shift, cuts in and provides
torque to the engine thus preventing excessive drive
wheel drive which, especially in poor grip conditions,
can lead to a loss of stability. ASR SYSTEM (Antislip Regulator)
This is a traction control system that cuts in
automatically every time one or both drive wheels slip.
Depending on the slipping conditions, two different
control systems are activated:
❒if the slipping involves both drive wheels, the ASR
function intervenes by reducing the power
transmitted by the engine;
❒if the slipping only involves only one driving wheel,
the ASR system cuts in by automatically braking the
wheel that is slipping.
The action of the
ASRis particularly helpful in the
following circumstances:
❒slipping of the inner wheel when cornering due to
the effect of dynamic load changes or excessive
acceleration;
❒too much power transmitted to the wheels also in
relation to the conditions of the road surface;
❒acceleration on slippery, snowy or icy surfaces;
❒loss of grip on a wet surface (aquaplaning).
For the correct operation of the ESP and
ASR systems, the tyres must absolutely be
the same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.
