coolant temperature FIAT DUCATO 2018 Owner handbook (in English)

During fully automatic system
operation, you can change the set
temperature, air distribution and fan
speed at any time by using the relevant
buttons or knobs: the system will
automatically change its settings to
adjust to the new requirements. During
fully automatic operation (FULL AUTO),
the word FULL will disappear if the air
distribution and/or flow rate and/or
engagement of the compressor and/or
recirculation settings are changed. In
this way, the functions will switch from
automatic to manual control until the
AUTO button is pressed again.
WARNING
2)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 linked to the type of cooling gas,
please refer to a Fiat Dealership.
ADDITIONAL
HEATER
(for versions/markets, where provided)
On some versions, an additional heater
is also present beneath the driver's
seat. The fan for this heater is operated
by means of the button F located on
the control panel fig. 75.
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.

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.

KNOWING YOUR VEHICLE

manualpressing the “immediate
heating” button on the timer again
(flame button 6).
The heating warning light and the
display light are switched off. The fluid
circulation pump keeps working for
approximately two minutes: the heater
can be switched back on again during
this time.
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.
ADDITIONAL REAR
HEATING (Panorama and
Combinato)
(for versions/markets, where provided)
The Panorama and Combi versions
are equipped with a main heating
system plus an additional system
(available on request) with controls in
the roof panel trim above the second
row of seats fig. 77.For it to operate, it must be enabled
using the button F fig. 78 on the control
panel.
Turn the knob D to the maximum cold
position (knob at blue sector); air at
ambient temperature will come out of
the rear footwell vents (located under
the seats in the 2nd and 3rd row for
Panorama versions and the grille on the
left wheel arch side for Combi
versions);77F1A0062

What it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds. The warning light turns on when the engine
is overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off
the engine and check that the water level in the
reservoir is not below the MIN mark. In this case, 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 itself. 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 that the coolant level is
correct 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 switches on when the ignition key is
turned to MAR, but it should switch off as soon as the
engine has started (with the engine idling a brief delay
before switching off is acceptable).If the warning light stays on, contact a Fiat Dealership
immediately.
