21) VEHICLE REFUELLING
•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.
•During normal service the catalyst reaches high temperatures;
therefore do not park the car over inflammable materials (grass,
dry leaves, pine needles, etc.): fire hazard.
•Do not use a mobile phone near the refuelling pump: risk of fire.
22) SEAT BELTS - PRETENSIONERS
•Do not press the seat belt release button while the vehicle is
moving.
•Remember that in the event of an accident, the rear seat
passengers not wearing seat belts are exposed to a very serious
risk and also represent a serious danger for the front seat
occupants.
•The pretensioner may be used only once. Contact a Fiat
Dealership to have it replaced after it has been deployed.
•For maximum safety, keep the backrest upright, lean back into
it and make sure the seat belt fits closely across your chest and
pelvis. Always fasten the seat belts on both the front and the rear
seats.
•Travelling without wearing seat belts will increase the risk of
serious injury and even death in the event of an accident.
•Removing or tampering with seat belt and pretensioner
components is strictly prohibited. Any intervention on these
components must be performed by qualified and authorised
technicians. Always go to a Fiat Dealership.

19) START&STOP SYSTEM
•When replacing the battery, always go to a Fiat Dealership.
Replace the battery with one of the same type (HEAVY DUTY)
and with the same specifications.
•Before opening the bonnet, make sure that the vehicle is
switched off and the key is in the STOP position.
Please follow the instructions on the decal near the front
crossmember. It is advisable to extract the key when there are
other people in the car.
The car should always be left after the key has been removed
or turned to the STOP position. When refuelling, make sure
that the car is switched off with the key in the STOP position.
•For cars with Dualogic gearbox, if the engine is
automatically stopped on a slope, the engine should be
restarted by moving the gear lever
to + or – without –releasing the brake pedal.
For vehicles with Dualogic transmission, where the Hill Holder
function is present, in case of stop downhill the motor does
not cut off automatically, so as to make the Hill Holder
function - which is active only when the engine is running -
available.
•If climate comfort is to be favoured, the Start&Stop system
can be disabled, for a continuous operation of the climate
control system.
20) ACCESSORIES PURCHASED BY THE OWNER
Take care when fitting additional spoilers, alloy wheels or non-
standard wheel hubs: they could reduce the ventilation of the
brakes and affect efficiency under sharp, repeated braking or
on long descents. Make sure that nothing obstructs the pedal
stroke (mats, etc.).

195
•Remember that the servo-brake and power steering are not
operational until the engine has been started, therefore much
effort than usual is required on the brake pedal and steering
wheel.
•For vehicles featuring a Dualogic gearbox, if the engine is not
started with a gear engaged, a warning is sounded to notify
the driver of the potential danger due to the gear being
automatically put into neutral.
•This starting procedure must be performed by expert
personnel because incorrect actions could cause electrical
discharge of considerable intensity. Furthermore, battery fluid
is poisonous and corrosive: avoid contact with skin and eyes.
Keep naked flames and lighted cigarettes away from the
battery and do not cause sparks.
•Remove any metal objects (e.g. rings, watches, bracelets),
that might cause an accidental electrical contact and cause
serious injury.
•Do not attempt to charge a frozen battery: it must be thawed
first, otherwise it may explode.
If freezing has occurred, the battery should be checked by
skilled personnel to make sure that the internal elements are
not damaged and that the body is not cracked, with the risk of
leaking poisonous and corrosive acid.
27) HANDBRAKE
• The car should be braked after a few clicks of the lever, if it is
not, contact a Fiat Dealership to have it adjusted.
• Never leave children in the unattended car. Always remove
the ignition key when leaving the car and take it out with you. • In the case of parking manoeuvres on roads on a gradient, the
front wheels must be steered towards the pavement
(when parking downhill), or in the opposite direction if the vehicle
is parked uphill. Block the wheels with a wedge or a stone if the
car is parked on a steep slope.
28) USING THE MANUAL GEARBOX
Press the clutch pedal fully to change gears correctly. It is
therefore essential that there is nothing under the pedals: make
sure the mats are lying flat and do not get in the way of the pedals.
29) TOWING TRAILERS
•The ABS with which the car is equipped will not control the
braking system of the trailer. Particular caution is required on
slippery roads.
•Do not, under any circumstances, modify the vehicle braking
system to control the trailer breaking system.
The towing braking system must be completely independent of the
vehicle’s hydraulic system.
30) SNOW TYRES
The maximum speed for snow tyres marked
“Q” is 160 km/h, while it is 190 km/h for “T” tyres and 210 km/h for
“H” tyres.
The highway code speed limits must however always be complied
with.
31) WARNING LIGHTS AND MESSAGES
•If the warning light
xturns on when travelling (on certain
versions together with the message on the display) stop the car
immediately and contact a Fiat Dealership.

PERSONAL SAFETY
(CONTINUED)
Do not use the jack for loads higher than the one shown on its
label. Never start the engine with vehicle raised. If the vehicle is
raised more than necessary, everything can become more
unstable, with the risk of the vehicle dropping violently.
Thus, lift the vehicle only as needed in order to access the
spare tyre.
33) FIX&GO QUICK TYRE REPAIR KIT
•The information required by the applicable regulation is
indicated on the Fix&Go kit package label. Carefully read the
label on the cartridge before use, avoid improper use. The kit
should be used by adults and cannot be used by children.
IMPORTANT: Do not exceed 80 km/h. Avoid sudden
acceleration or braking. The kit provides a temporary repair,
therefore the tyre must be examined and repaired by a
specialist as soon as possible. Before using the kit, ensure that
the tyre is not excessively damaged and that the rim is in good
condition, otherwise do not use it and call roadside assistance.
Do not remove foreign bodies from the tyre. Do not let the
compressor turned on for more than 20 consecutive minutes -
overheating hazard.
34) CHANGING A BULB
•Modifications or repairs to the electric system that are not
carried out properly or do not take the system technical
specifications into account can cause malfunctions leading to
the risk of fire.
•Halogen bulbs contain pressurised gas, in the case of
breakage they may burst causing glass fragments to be
projected outwards.
•Due to the high power supply voltage, gas discharge bulbs
(Xenon) should only be replaced by specialised personnel:
danger of death! Contact a Fiat Dealership.35) REPLACING FUSES
•If the replaced fuse blows again, contact a Fiat Dealership.
•Never replace a fuse with metal wires or anything else.
•Never replace a fuse with another with a higher amp rating; RISK
OF FIRE.
•If a general fuse (MEGA-FUSE, MIDI-FUSE,
MAXI-FUSE) blows contact a Fiat Dealership.
•Before replacing a fuse, make sure that the ignition key has
been removed and that all the other services are switched off
and/or disengaged.
•Contact Fiat Dealership if a safety system (airbags, brakes),
engine system
(engine, gearbox) or steering system general protection fuse
blows.
36) BATTERY RECHARGING
•Battery fluid is poisonous and corrosive:
avoid contact with your skin and eyes. The battery should be
charged in a well ventilated place, away from naked flames or
possible sources of sparks: danger of explosion and fire.
•Do not attempt to charge a frozen battery: it must be thawed
first, otherwise it may explode.
If freezing has occurred, the battery should be checked by skilled
personnel to make sure that the internal elements are not
damaged and that the body is not cracked, with the risk of leaking
poisonous and corrosive acid.
37) TOWING THE CAR
•Before tightening the ring clean the threaded housing thoroughly.
Make sure that the ring is fully fastened in the housing before
towing the car.

PERSONAL SAFETY
(CONTINUED)
• The electronic Cruise Control can be dangerous if the system is
unable to maintain a constant speed. In specific conditions speed
may be excessive, resulting in the risk of losing control of the
vehicle and causing accidents. Do not use the device in heavy
traffic or on winding, icy, snowy or slippery roads.
39) SERVICING - CHECKING FLUID LEVELS
•Never smoke while working in the engine compartment: gas
and inflammable vapours may be present, with the risk of fire.
•Be very careful when working in the engine compartment when
the engine is hot: you may get burned. Remember that when the
engine is hot, the fan may operate: danger of injury. Scarves, ties
and other loose clothing might be pulled by moving parts.
•The cooling system is pressurised. If necessary, only replace
the plug with another original or the operation of the system may
be adversely affected. Do not remove the reservoir plug when the
engine is hot: you risk scalding yourself.
•Do not travel with the windscreen washer fluid reservoir empty:
the windscreen washer is essential for improving visibility.
•Some commercial windscreen washer additives are flammable.
The engine compartment contains hot components which may
set it on fire.
•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.
•Symbol
πon the contain indicates a synthetic brake fluid,
which is different from a mineral fluid.
Use of a mineral type fluid will damage the special rubber seals of
the braking system beyond repair.
•Battery fluid is poisonous and corrosive. Avoid contact with skin
and eyes. Keep naked flames and sources of sparks away from
the battery: risk of explosion and fire. •Before towing, turn the ignition key to MAR and then to STOP
without removing it. The steering column will automatically lock
when the key is removed and the wheels cannot be steered.
•When towing, remember that without the help of the brake
servo and electric power steering, a greater effort is required on
the pedal and steering wheel.
•Do not use flexible cables when towing and avoid jerky
movements.
•During towing, make sure that the trailer hitch does not
damage any components it is touching.
•When towing the vehicle, you must comply with all specific
traffic regulations, both in terms of the towing device and
behaviour on the road.
•Do not start the engine while towing the car.
•The (front/rear) tow hook must be used exclusively for
roadside assistance operations.
You are allowed to tow the vehicle for short distances using an
appropriate device in accordance with the highway code (a rigid
bar), to move the vehicle on the road in readiness for towing or
transport via a breakdown vehicle.
The tow hook MUST NOT be used to tow vehicles off the road
or where there are obstacles and/or for towing operations using
cables or other non-rigid devices. In compliance with the above
conditions, towing must take place with the two vehicles (one
towing, the other towed) aligned as much as possible along the
same centre line.
38) ELECTRONIC CRUISE CONTROL
•Never move the shift lever to neutral when driving with the
device active.
• In the event of device malfunction or failure, contact a Fiat
Dealership.

PERSONAL SAFETY
(CONTINUED)
42) INTERIORS
•Never use flammable products, such as petrol ether or rectified
petrol to clean the inside of the car. The electrostatic charges which
are generated by rubbing during the cleaning operation may cause
a fire.
•Do not keep aerosol cans in the vehicle: they might explode.
Aerosol cans must not be exposed to a temperature exceeding
50°C. When the vehicle is exposed to sunlight, the internal
temperature can greatly exceed this value.
43) TECHNICAL SPECIFICATIONS – FUEL SUPPLY
Modifications or repairs to the supply system that are not carried
out correctly or do not take the system technical specifications
into account can cause malfunctions leading to the risk of fire.
44) TECHNICAL SPECIFICATIONS – RIM PROTECTOR
TYRES
DO NOT fit wheel hub caps when using integral hub caps fixed
(with springs) to the steel rim and after sale tyres provided with
Rim Protector. Use of unsuitable tyres and wheel caps may cause
sudden decrease of tyre pressure.
45) LPG
•Note that in some countries (including Italy) there are legal
restrictions in force for parking/garaging motor vehicles fuelled by
gas that is denser than air; LPG comes under this category.
•Do not switch between the two operating modes (petrol/LPG)
whilst starting the engine.
•The LPG supply system is equipped with a “consumption”
function linked to the LED display of LPG level on the switch; this
function activates only after a consistent variation in fuel level has
been detected. •Running the battery with an excessively low liquid level will
damage the battery beyond repair and could even cause its
explosion.
•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.
•When performing any operation on the battery or near it,
always protect your eyes with special goggles.
40) TYRES AND WHEELS
•Remember that the road holding qualities of your car also
depend on correct tyre pressures.
•If tyre pressure is too low, the tyre may overheat and be
severely damaged as a result.
•Do not switch tyres from the right hand side of the vehicle to the
left hand side, and vice versa.
•Never submit alloy rims to repainting treatments requiring the
use of temperatures exceeding 150°C.
The mechanical properties of the wheels could be impaired.
41) WINDSCREEN AND –REAR WINDOW WIPER
•Driving with worn windscreen/rear window wiper blades is a
serious hazard, because visibility is reduced in bad weather.
•If the window needs to be cleaned, make sure the device is
deactivated or the key is on STOP.
IMPORTANT INFORMATION AND RECOMMENDATIONS
(CONTINUES)

203
•Never use alcohol, petrol, chemical products, detergents,
stain removers, wax, solvents and “wash and polish” products.
•Rinse immediate to remove soap to prevent stains. Repeat
the operation if needed.
•Rinse immediately, and repeat this operation if necessary.
If you choose to waterproof the soft top, strictly follow the
instructions on the package of the waterproofing product you
have selected in order to obtain optimal results.
•The rubber seals on the soft top must be cleaned exclusively
with water. If you notice that this trim is dry or is sticking, apply
talcum powder or products specifically for rubber trim (silicone
spray).
7) ROOF RACK/SKI RACK
The use of transversal bars on longitudinal ones prevents the
use of the sunroof, because the latter, while opening, interferes
with the bars. Therefore do not move the sunroof if transversal
bars have been fitted.
8) EOBD SYSTEM
If, when the ignition key is turned to the MAR position, the
Uwarning light either does not come on or, when driving, it
comes on constantly or flashing (along with a message in the
display, for versions/markets, where provided) contact a Fiat
Dealership as soon as possible. The operation of the
Uwarning light may be checked by traffic police using appropriate
equipment. Comply with the laws and regulations of the country
where you are driving.
9) DOORS
Make sure to take the key with you once a door or the tailgate
is locked, to prevent locking the same key inside the vehicle.
If the key has been locked in, it can only be recovered using
the second provided key.10) MULTIMEDIA
• Only clean the front panel and the display lens with a soft,
clean, dry, anti-static cloth.
Cleaning and polishing products may damage the surface. Never
use alcohol, petrols and derivatives.
• Do not use the display as a base for supports with suction pads
or adhesives for external navigators or smartphones or similar
devices
11) REFUELLING YOUR DIESEL ENGINE VEHICLE
Vehicles with a diesel engine must only be filled with diesel fuel for
motor vehicles, in compliance with European Standard 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.
12) SEAT BELTS - PRETENSIONERS
Operations which lead to impacts, vibrations or localised heating
(over 100°C for a maximum of six hours) in the area around the
pretensioner may damage or deploy it. Contact a Fiat Dealership
should intervention be necessary on these components.
13) STARTING AND STOPPING THE ENGINE
• It is advisable not to demand maximum performance from your
car (e.g. excessive accelerations, long distances at top rpm,
excessive intense braking, etc.) as soon as the engine is started.
• When the engine is switched off never leave the key turned to
MAR to prevent useless current absorption from draining the
battery.

1) KEYS - REMOTE CONTROL
Used batteries should be disposed of, as specified by law, in
the special containers, otherwise take them to a Fiat
Dealership, which will deal with their disposal.
2) CLIMATE CONTROL SYSTEM
The system uses R1234yf coolant, which is compatible with
the laws in force in the countries where the vehicle is sold.
When charging, only use the gas indicated on the 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 refrigerant gas type,
refer to the Fiat Dealership.
3) SERVICING - CHECKING FLUID LEVELS
• Used engine oil and oil filters contain substances which are
harmful to the environment. To change the oil and filters, we
advise you to contact a Fiat Dealership.
• Used transmission fluid contains substances that are harmful
to the environment. It is advisable to have the oil changed by a
Fiat Dealership where it will be disposed of respecting the
environment and according to legal requirements.
•Batteries contain substances which are very dangerous for the
environment. It is advisable to contact a Fiat Dealership for
battery replacement.
