(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of 5 seconds until
the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on
as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is
now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the car for short drives, preventing the engine from
reaching operating temperature.
Contact a Fiat Dealership as soon as possible.

WARNING
31)If, when the ignition device is turned to MAR, thewarning light does not switch on or stays on whilst driving, a failure may have
occurred in the restraint systems. In this case the airbags or pretensioners may not be deployed in an impact or, in a lower number of cases,
they may be deployed accidentally. Before continuing, contact a Fiat Dealership immediately to have the system checked.
32) The fault of the
warning light is signalled by the switching on of theicon on the instrument panel. In this case, the warning light may
not indicate any faults with the restraint systems. Before continuing, contact a Fiat Dealership immediately to have the system checked.
33) If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
IMPORTANT
24)If, turning the ignition device to MAR, thewarning light does not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact a Fiat Dealership as soon as possible.
25) If the warning light (or the icon on the display) flashes whilst driving, contact a Fiat Dealership.
26) If the symbol switches on when driving, stop the engine immediately and contact a Fiat Dealership.
27) Driving the vehicle with this symbol on may severely damage the gearbox, with resulting breakage. The oil may also overheat: contact with
hot engine or with exhaust components at high temperature could cause fires.
28) The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact a Fiat Dealership as soon as possible to bleed the system. If the above indications come on immediately after
refuelling, water has probably been poured into the tank: switch the engine off immediately and contact a Fiat Dealership.
29) Vehicle travel speed should always be adapted to the traffic and weather conditions, and must always comply with traffic regulations. The
engine can be stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason it is always advisable to wait for the symbol to go off before turning off the engine,
following the instructions above. Do not complete the DPF regeneration process when the vehicle is stopped.
30) If the
warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from
the first switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty.
Remember that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you do not need to top up
the engine oil.
31) If the symbol flashes when driving, contact a Fiat Dealership.

USEFUL ADVICE FOR
EXTENDING THE LIFE OF
YOUR BATTERY
Useful advice for extending the life
of your battery
To avoid draining your battery and
make it last longer, observe the
following instructions:
when you park the vehicle, ensure
that the doors, tailgate and bonnet are
closed properly, to prevent any lights
from remaining on inside the passenger
compartment;
switch off all roof lights inside the
vehicle: the vehicle is however
equipped with a system which switches
all interior lights off automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before performing any operation on
the electrical system, disconnect the
negative battery cable.
If, after purchasing the vehicle, you wish
to install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
influence the electrical supply
requirements, contact a Fiat Dealership,
whose qualified staff will evaluate the
overall electrical consumption.
91)
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel (or symbol on the
display) switches on to indicate this. To
carry out this procedure, simply turn the
steering wheel all the way from one end
to the other or drive in a straight line for
about a hundred metres.
IMPORTANT If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing its
capacity and efficiency at start-up. The
battery is also more prone to the risk of
freezing (at temperatures of -10°C).
Refer to the "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.
WARNING
166) Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of
fire.
167) Be very careful when working in the
engine compartment when the engine is
hot: you may get burned.
168) If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler cap, particularly for
vehicles with aluminium cap (where
provided). WARNING: risk of burns!
195

169)The cooling system is pressurised. If
the cap needs replacing, do so with
another original or the effectiveness of the
system may be compromised. Do not
remove the reservoir plug when the engine
is hot: you risk scalding yourself.
170) Do not travel if the windscreen
washer reservoir is empty: using the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
171) Some commercial additives for
windscreen washer fluid are flammable.
The engine compartment contains hot
components which may start a fire.
172) Brake fluid is poisonous and highly
corrosive. In the event of accidental
contact, immediately wash the affected
parts with water and mild soap. Then rinse
thoroughly. Call a doctor immediately if
swallowed.
173) The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral-based. Use of mineral
type fluids will damage the special rubber
seals of the braking system beyond repair.
174) Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
175) Using the battery with insufficient fluid
irreparably damages the battery and may
cause an explosion.
176) When performing any operation on
the battery or near it, always protect your
eyes with special goggles.
IMPORTANT
85) Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping up
with an unsuitable fluid could severely
damage your vehicle.
86) The oil level must never exceed the
MAX. mark.
87) Always top up using engine oil of the
same specifications as that already in the
engine.
88) PARAFLU
UPanti-freeze is used in the
engine cooling system. Use fluid of the
same type as that contained in the cooling
system for any top-ups. PARAFLU
UP
cannot be mixed with any other type of
fluid. If this happens, do not start the
engine under any circumstances and
contact a Fiat Dealership.
89) Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen,
immediately wash with water.
90) If the vehicle must remain unused for a
long time at a very low temperature,
remove the battery and take it to a warm
place, to avoid freezing.
91) Incorrect installation of electric and
electronic devices may cause severe
damage to your car. After purchasing your
vehicle, if you wish to install any
accessories (e.g. anti-theft, radio phone,
etc.), go to a Fiat Dealership, which will
suggest the most suitable devices and
advise you whether a higher capacity
battery needs to be installed.
IMPORTANT
3) The used engine oil and the filter that has
been replaced contain substances that are
harmful to the environment. To change the
oil and filters, we advise you to contact a
Fiat Dealership.
4) Used transmission fluid contains
substances that are harmful to the
environment. It is advisable to contact a
Fiat Dealership to have the fluid changed.
5) Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact a Fiat
Dealership.

SERVICING AND MAINTENANCE

EXHAUST SYSTEM
178) 179)
98)
Adequate maintenance of the engine
exhaust system represents the best
protection against leaks of carbon
monoxide into the passenger
compartment.
AUTOMATIC
TRANSMISSION
99)
Use only a gearbox fluid with the same
characteristics as those indicated in the
"Fluids and lubricants" table (see
"Technical specifications" chapter).
WARNING
177)The air intake system (air cleaner,
rubber hoses, etc.) can be a protection in
the case of blowbacks from the engine. DO
NOT REMOVE this system unless you
need to carry out repair or servicing
operations. Before starting the engine,
ensure that the system has not been
removed: failure to observe this precaution
may result in serious injury. 178)
Exhaust emissions are very
dangerous, and may be lethal. They
contain carbon monoxide, a colourless,
odourless gas which can cause fainting
and poisoning if inhaled.
179) The exhaust system may reach high
temperatures and may cause a fire if the
vehicle is parked on flammable material.
Dry grass or leaves can also catch fire if
they come into contact with the exhaust
system. Do not park or use the vehicle in a
place in which the exhaust system might
come into contact with flammable material.
IMPORTANT
92) It is recommended to have the vehicle
serviced by a Fiat Dealership. When
carrying out normal periodic operations and
small servicing interventions personally on
the vehicle, it is recommended to use
suitable equipment, genuine spare parts
and the necessary fluids. Do not carry out
any interventions if you don't have the
necessary experience.
93) Incorrect servicing of the vehicle or
failure to carry out operations or repairs
(when necessary) may lead to more
expensive repairs, damage to other
components or have a negative impact on
the vehicle performance. Have any
malfunction inspected immediately by a Fiat
Dealership. 94)
The vehicle is equipped with fluids
which are optimised or protecting its
performance and life and extending service
intervals. Do not use chemicals for washing
these components since they may damage
the engine, the gearbox or the climate
control system. This damage is not covered
by the vehicle’s warranty. If any component
needs to be washed due to malfunctioning,
use only the specific liquid for that
procedure.
95) An excessive or insufficient amount of
oil inside the base is extremely damaging to
the engine. Make sure it is always at an
adequate level.
96) Always require the use of only
compressor coolants and lubricants
approved and suitable for the specific air
conditioning system fitted on the vehicle.
Some non-approved coolants are
flammable and may explode, with the risk
of injuries. The use of non-approved
coolants or lubricants may adversely affect
system efficiency, leading to expensive
repairs.
97) The air conditioner system contains
coolant under high pressure: to avoid
injuries to people or damage to the system,
any coolant addition or repair that requires
to disconnect the cables must be carried
out by a Fiat Dealership.
