engine overheat FIAT DUCATO 2015 3.G Owners Manual

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 heater is equipped
with a thermal limiter that cuts off
combustion in the case of overheating
due to insufficient coolant/coolant
leaks. In this case, after repairing the
fault in the cooling system and/or
topping up the fluid, press the program
selection button before turning the
heater back on.
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
heater back on. If it still does not work,
consult a Fiat Dealership.Activation of the heating
system
When an automatic climate control
system is present, the control unit sets
the air temperature and distribution
when the heater is turned on from the
park position. When a manual
heater/climate control is present, to
obtain maximum heater efficiency,
check that the passenger compartment
heating/ventilation temperature
adjustment knob is in the 'hot air'
position.
To prioritise passenger compartment
pre-heating, set the air distribution knob
to the
position.
To prioritise windscreen demisting, set
the air distribution knob to
position.
To obtain both functions, set the air
distribution knob to
position.

KNOW YOUR VEHICLE

After reaching the desired speed,
release the accelerator and brake
pedals completely (the LED on the
button flashes). If you want to
increase/decrease the speed, press the
accelerator/brake pedals again.
IMPORTANT Do not use the device
with the gearbox in neutral position.
IMPORTANT It is important to engage a
gear suitable for the set speed, to
prevent the engine from stalling.
When this function is active the brake
lights turn on automatically.
While the HDC system is operating it is
also possible to take control of the
vehicle again by pressing the brake and
accelerator pedals.
If the function is not made available
when the button is pressed, this could
be due to brake overheating. In this
case, wait a few minutes before using
the function again.
IMPORTANT The system is available for
speeds below 25 km/h.IMPORTANT Above 25 km/h the HDC
system deactivates but is still ready
to operate (the LED on the button
remains on) when the speed is again
below 25 km/h. If the speed exceeds
50 km/h, the HDC system deactivates
completely (the LED on the button
switches off) and the function does not
operate autonomously on the brakes
anymore. To reactivate it, press the
dedicated button again when the speed
is again below 25 km/h.

WARNING
58) The ESC system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
59) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.60) The capability of the ESC system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
61) The performance of the ESC and
ASR systems must not encourage
the driver to take unnecessary
risks. Driving style must always be
adapted to road conditions,
visibility and traffic. The driver is,
in any case, responsible for safe
driving.
62) For the ESC and ASR systems to
function correctly, all four tyres
must be the same brand and type,
must be in excellent condition
and, above all, must be of the
prescribed type and size.
63) The HBA system cannot increase
tyre grip on the road over the
limits imposed by laws of physics:
always drive carefully according
to the conditions of the road
surface.
64) The HBA system cannot prevent
accidents, including those due to
excessive speed on bends,
travelling on low-grip surfaces or
aquaplaning.
85

65) The HBA system is an aid for the
driver, who must always pay full
attention while driving. The
responsibility always rests with
the driver. The features of the
HBA system must never be tested
in imprudent or dangerous ways,
with the possibility of putting
the safety of the driver, occupants
or other road users at risk.
66) The performance of a vehicle
with ERM must never be tested
in imprudent or dangerous ways,
with the possibility of putting
the safety of the driver or other
people at risk.
IMPORTANT
8) Prolonged use of the system may
overheat the braking system. If
the brakes overheat, the HDC
system, when active, will be
gradually deactivated after
suitably informing the driver (the
LED on the button turns off): it
can be reactivated only when the
brakes have cooled sufficiently.
The distance that can be covered
depends on the temperature of
the brakes and therefore on the
gradient, load and speed of the
vehicle.
TRACTION PLUS
SYSTEM
(for versions/markets, where provided)
Traction Plus is a driving aid, useful
for setting off in poor grip conditions on
non-homogeneous road surfaces
(snow/asphalt, ice/asphalt, mud/
asphalt, etc.), which allows the drive
force to be distributed adequately
on the engine axle when one of the two
drive wheels slips.
Traction Plus acts by braking the wheel
with poor grip (or slipping more than
the others), thereby transferring the
drive force to that which has greater
grip on the ground.
This function can be activated manually
by pressing button A on the dashboard
fig. 127 and operates under 50 km/h.
When this speed is exceeded, it is
automatically deactivated (the LED on
the button is still on) and it is
reactivated again when the speed falls
below 30 km/h.

WARNING
92) Do not bring naked flames or lit
cigarettes near to the fuel tank
opening: fire risk. Keep your face
away from the fuel filler to prevent
breathing in harmful vapours.
93) To avoid fuel spillage and the
exceeding of the maximum level,
avoid topping up after filling the
tank.
94) Any fuel pumping in portable
containers located on a floor
can cause a fire. Danger of burns.
Always put the fuel container on
the ground during filling. Avoid
using contaminated fuel: a fuel
contaminated with water or earth
can cause serious damage to
the motor supply. Proper
maintenance of the fuel filter, of
the engine and the fuel tank is
essential.
95) Do not open the fuel system at
high pressure with the engine
running. The operation of the
engine creates a high fuel
pressure. A jet of high-pressure
fuel can cause serious injury or
death.
WARNING
96) If AdBlue overheats for a
prolonged period inside the tank
to over 50 ° C (for example due
to direct solar irradiation), AdBlue
can decompose ammonia
vapours. Ammonia vapours have a
pungent odour when the cap of
the AdBlue tank is unscrewed,
therefore be careful not to inhale
any ammonia vapours in the tank
outlet. In this concentration,
however, the ammonia vapors are
not harmful or dangerous to
health.
PROTECTING THE
ENVIRONMENT
The following devices are used for
reducing diesel fuel engine emissions:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(EGR);
❒particulate filter (DPF) (for versions/
markets, where provided).
97)
DIESEL PARTICULATE
FILTER (DPF)
The Diesel Particulate Filter is a
mechanical filter, integral to the exhaust
system, that physically traps carbon
particles present in the exhaust gases
of diesel engines.
The diesel particulate filter has been
adopted to eliminate almost all
particulates in compliance with current /
future legal regulations.
During normal use of the vehicle, the
Powertrain Control Module records
a set of data (travel time, type of route,
temperatures reached etc.) and
calculates how much particulate has
been trapped by the filter.

Warning lights on
displayWhat it means What to do
ENGINE COOLANT TEMPERATURE
TOO HIGH
When the key is turned to MAR-ON, the
warning light switches on but should switch
off after a few seconds. The warning light
turns on when the engine is overheated.
The display shows the dedicated message.When driving normally: stop the vehicle, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. If it is, wait for the engine to
cool down then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir. Also check
visually for any fluid leaks. If, when restarting, the
warning light switches on again, contact a Fiat
Dealership.
If the vehicle is used under demanding conditions (e.g.
in high-performance driving): slow down and, if the
warning light stays on, stop the vehicle. Wait for 2 or 3
minutes with the engine running and slightly
accelerated to further favour the coolant circulation,
then stop the engine. Check the correct coolant level as
described above.
IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
redLOW BATTERY CHARGE
The warning light comes on when the
ignition key is turned to MAR-ON, but it
should go out as soon as the engine has
started (with the engine running at idle
speed a brief delay before going out is
acceptable).If the warning light stays on, contact a Fiat Dealership
immediately.
