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.
34)
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.PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:
heating 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. 63 for turning the
heater on manually or for programming
its turn-on time.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.

What it means What to do
“COMFORT-MATIC" GEARBOX FAILURE
The warning light comes on when the ignition key is
turned to MAR, but should go off after a few seconds.
The warning light in the panel comes on flashing
(together with a message in the reconfigurable
multifunction display and a buzzer) to indicate that the
gearbox is faulty.If the transmission is faulty, contact a Fiat Dealership
as soon as possible to have the system checked.
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light comes on when the ignition key is
turned to MAR, but should go 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.

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
corresponding button A fig. 83; the LED
on the button turns on and the display
shows a dedicated 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 On exceeding 25 km/h,
the HDC system is disabled and
remains ready to operate again (the
LED on the button remains on) when
the vehicle returns below 25 km/h.
If the vehicle speed exceeds 50 km/h,
the HDC system turns off completely
(the LED on the button turns off) and
any autonomous action on the brakes
is disabled. To reactivate it, press the
dedicated button again when the speed
is again below 25 km/h.
12)
WARNING
57)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.
58)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
59)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.
60)For the correct operation of the ESC
and ASR system it is vital that the tyres are
the same make and the same type on all
the wheels, in perfect condition and, above
all, the recommended type and size.
61)The performance of the ESC and ASR
systems must not encourage the driver
to take unnecessary risks. Driving style
must always be suitable for road
conditions, visibility and traffic. The driver
is, in any case, responsible for safe driving.
62)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.
63)The HBA system cannot prevent
accidents, including those due to excessive
speed on bends, travelling on low-grip
surfaces or aquaplaning.

SAFETY

64)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.
65)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.
WARNING
12)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 you can travel depends on the
brake temperature and thus on the slope,
the load and the vehicle speed.
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. 84 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.
66) 67)
Traction Plus operation
The system is deactivated when
starting. To activate the Traction Plus
system, press button A fig. 84: the LED
on the button switches on.The activation of the Traction Plus
system involves the following functions
being switched on:
inhibition of the ASR function, in
order to fully exploit the engine torque;
the differential locking effect on
the front axle, through the braking
system, to improve traction on irregular
grounds.
If the Traction Plus system is faulty, the
warning light on the instrument
panel switches on constantly.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the Traction Plus on and thus inhibiting
the ASR function: in fact, in these
conditions, slipping of the drive wheels
when moving off makes it possible to
obtain better traction.

WARNING
128)Do not approach naked flames or lit
cigarettes to the fuel tank filler: fire risk.
Keep your face away from the fuel filler to
prevent breathing in harmful vapours.
129)To avoid fuel spillage and the
exceeding of the maximum level, avoid
topping up after filling the tank.
130)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.
131)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.
132)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
34)Only refuel with automotive diesel
complying with the European specification
EN 590. The use of other products or
mixtures may damage the engine beyond
repair and consequently invalidate the
warranty, due to the damage caused. If
you accidentally introduce other types of
fuel into the tank, do not start the engine.
Empty the tank. If the engine has been run
for even an extremely limited amount of
time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
35)Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired. The check
valve prevents the methane from flowing
back to the fuel filler.
36)If the vehicle has been registered in a
country other than Italy, the certification
data, identification and inspection
procedures for the methane cylinders
should conform to the legislation in that
country. In any case, it should be
remembered that the life of the cylinders is
20 years from the production date as set
out in ECE Regulation no. 110.
ADDITIVE FOR
DIESEL EMISSIONS
ADBLUE (UREA)
The vehicle is equipped with a Selective
Catalytic Reduction system to meet
the strict Diesel emissions standards
required by the Agency for
Environmental Protection.
The purpose of the system of Selective
Catalytic Reduction is to reduce the
nitrogen oxides levels emitted by
engines; these elements are harmful to
our health and to the environment
even at minimum levels. A small
amount of additive for Diesel emissions
AdBlue (UREA) is injected upstream
of the catalyst exhaust outlet where,
when it turns into gas, converts
nitrogen oxides, that create smog, in
simple nitrogen and water vapour, two
natural components of air we breathe.
You can use your vehicle with the
peace of mind of knowing that you are
contributing to a cleaner and healthy
environment for future generations.
System description
The vehicle is equipped with an UREA
fuel injection system and a Selective
Catalytic Reduction catalyst to meet the
emission standards.
