overheating FIAT DUCATO 2015 Owner handbook (in English)

❒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 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.

HILL DESCENT
CONTROL (HDC)
SYSTEM
It is an integral part of the ESC and
is aimed at keeping the vehicle at
a constant speed during a descent,
operating autonomously on the
brakes in various ways at the same
time. In this way the vehicle stability
and completely safe driving are
guaranteed, above all in poor grip
conditions and/or steep descents.
To activate the system reach a
speed slower than 25 km/h and
press the dedicated key A fig. 126;
the LED on the button turns on
and the display gives a specific
message.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.

TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where
provided)
69) 70) 71) 72) 73) 74) 75) 76) 77)
DESCRIPTION
The tyre pressure monitoring
system (TPMS) warns the driver of
low tyre pressure on the basis of
the cold inflation pressure
prescribed for the vehicle.
Changes in outside temperature
may cause tyre pressure to vary.
This means that a decrease in the
outside temperature corresponds
to a decrease in the tyre pressure.
Tyre pressure must always be
adjusted according to the cold
inflation pressure. Cold tyre inflation
pressure is the tyre pressure after
letting the vehicle stand for at least
three hours or a travel shorter
than 1.6 km after an interval of
three hours.
The cold tyre inflation pressure
must not exceed the maximum
inflation pressure value printed on
the side of the tyre.The tyre pressure also increases
while driving the vehicle: this is
a normal condition and does not
require any adjustment of the
pressure.
The TPMS continues to advise the
driver of the low tyre pressure
condition until this is corrected; the
warning continues until the
pressure corresponds or exceeds
the pressure prescribed for the cold
tyres. When the tyre low pressure
control warning light
switches on
constantly, the inflation pressure
must be adjusted until it reaches
the pressure prescribed for cold
tyres. After the automatic update of
the system, the tyre pressure
control warning light switches off.
You may need to drive the vehicle
for about 20 minutes at a speed
higher than 20 km/h to allow the
TPMS to receive this information.NOTE
❒The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒Therefore, the TPMS should not be
used as pressure switch while
adjusting the tyre inflation pressure.
❒Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency
and tyre tread life and may also affect
handling and braking performance
of the vehicle.
❒The TPMS does not replace the
correct tyre maintenance. It is up to
the driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not
cause the tyre pressure control
warning light to switch on.
❒The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal
pressure loss of the tyre.
❒The seasonal temperature changes
affect tyre pressure.

WARNING
153) Give the instruction booklet to
the tyre repair workshop
personnel.
154) Punctures on the sides of the
tyre cannot be repaired. Do not
use the quick tyre repair kit if the
damage is due to running with flat
tyre.
155) If the wheel rim has been
damaged (bent so as to cause air
to leak), the wheel cannot be
repaired. Do not remove the
foreign body (screws or nails)
from the tyre.
156) Do not use the compressor for
more than 20 consecutive
minutes. Risk of overheating.
Tyres repaired with the quick tyre
repair kit must only be used
temporarily, as the kit is not
suitable for a definitive repair.157) The bottle contains ethylene
glycol. It contains latex that might
cause allergic reactions. It is
harmful if swallowed. It is irritant
for the eyes. It may cause
sensitisation if inhaled or on
contact. Avoid contact with eyes,
skin and clothes. In the event of
contact, wash immediately with
plenty of water. Do not induce
vomiting if swallowed. Rinse your
mouth and drink plenty of water.
Call a doctor immediately. Keep
out of the reach of children. The
product must not be used by
asthmatics. Do not breathe in the
vapours during insertion and
suction. Call a doctor immediately
if allergic reactions are noted.
Store the bottle in its proper
compartment, away from sources
of heat. The sealant has an expiry
date. Replace the bottle if the
sealant has expired.
158) Wear the protective gloves
provided together with the quick
tyre repair kit.
159) affix the adhesive label in an
easy-to-see position for the driver
as a reminder that the tyre has
been treated with the quick tyre
repair kit. Drive carefully,
particularly on bends. Do not
exceed 80 km/h. Do not
accelerate or brake suddenly.160) If the pressure falls below 3
bars, do not drive any further: the
Fix & Go automatic quick tyre
repair kit cannot guarantee proper
hold because the tyre is too much
damaged. Contact a Fiat
Dealership.
161) You must inform the dealership
that the tyre has been repaired
using the quick tyre repair kit.
Give the booklet to the personnel
who will be handling the tyre
treated with the repair kit.
162) If different tyres from the ones
supplied with the vehicle are
used, it may not be possible to
carry out the repair. If the tyres
are replaced, it is advisable to use
those approved by the
manufacturer. Consult a Fiat
Dealership.
IMPORTANT
44) Punctures caused by foreign
bodies can be repaired if the
damage does not exceed 4 mm on
the tread and on the shoulder of
the tyre.
207

WARNING
193) Remember that the road
holding qualities of your vehicle
also depend on the correct
inflation pressure of the tyres.
194) If the pressure is too low, the
tyre will overheat and could be
seriously damaged.
195) Avoid switching the tyres from
the right side of the vehicle to the
left side and vice versa.
196) Never submit alloy rims to
repainting treatments requiring
the use of temperatures
exceeding 150°C. The mechanical
properties of the wheels could
be impaired.
RUBBER HOSES
As far as the brake system and fuel
supply system rubber hoses are
concerned, follow the "Scheduled
Servicing Plan" in this chapter
carefully.
Ozone, high temperatures and
prolonged lack of fluid in the
system may cause hardening and
cracking of the hoses, with possible
leaks. Careful checking is therefore
necessary.
WINDSCREEN
WIPER
BLADES
Periodically clean the rubber part
using special products; TUTELA
PROFESSIONAL SC 35 is
recommended.
Replace the blades if the rubber
edge is deformed or worn. In any
case, it is advisable to replace them
approximately once a year.
A few simple precautions can
reduce the possibility of damage to
the blades:
❒if the temperature falls below zero,
make sure that ice has not frozen
the rubber against the glass. Use a
de-icing product to release it if
required;
❒remove any snow from the glass: in
addition to protecting the blades,
this prevents effort on the motor and
overheating;
❒do not operate the windscreen and
rear window wipers on dry glass.
