iTPMS System
(indirect Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
48)
RESET PROCEDURE
The iTPMS needs an initial “self-
learning” phase (with length depending
on the driving style and road
conditions: optimal conditions being
driving on a straight road at 80 km/h
for at least 20 minutes) which starts
when the Reset procedure is carried
out.
The Reset procedure must be carried
out:
❒ each time tyre pressure is
modified;
❒ when even only one tyre is
changed;
❒ when tyres are rotated/inverted;
❒ when the space-saver wheel is
fitted.
In a few situations such as sporty
driving, particular conditions of the
road surface (e.g. icy, snowy,
unsurfaced roads...) the signalling may
be delayed or partial in detecting the
contemporary deflation of more than
one tyre.
Under special conditions (e.g. vehicle
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, use of
the “Fix&Go” quick tyre repair kit,
fitting snow chains, fitting different
tyres on the axles) the system may
give false indications or be temporarily
deactivated.
If the system is temporarily
deactivated, the warning light
nflashes for about 75 seconds and then
is continuously on; at the same time,
the display shows a dedicated
message.
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored. Before carrying out the “Reset”
procedure, inflate the tyres to the
rated pressure values specified in the
inflation pressure table (see “Wheels”
paragraph in the “Technical
specifications” chapter).
If the Reset procedure is not carried
out, in all above cases, the
nwarning light may give false indications
on one or more tyres.
To carry out the Reset procedure, with
the vehicle stopped and the ignition
key at MAR, use the setup menu (see
the description of the “Display”
paragraph). At the end of the Reset
procedure the display will show the
“Reset saved” message, indicating
that the self-learning has been started.
If the iTPMS self-learning is not
correctly executed, the message is not
displayed.
OPERATING
CONDITIONS
The system is active for speeds above
15 km/h.

IMPORTANT INFORMATION AND RECOMMENDATIONS

PERSONAL SAFETY
(CONTINUED)
7) DAYTIME RUNNING LIGHTS (DRL)
•The daytime running lights are an alternative to the dipped
beam headlights for driving during the daytime in countries
where it is compulsory to have lights on during the day, and
they are also permitted in those countries where this is not
obligatory.
•Daytime running lights cannot replace dipped beam
headlights when driving at night or through tunnels.
•The use of daytime running lights is governed by the highway
code of the country in which you are driving. Comply with legal
requirements.
8) FUEL CUT-OFF SYSTEM
If, after an impact, you smell fuel or notice leaks from the fuel
system, do not reactivate the system to avoid the risk of fire.
9) INTERIOR FITTINGS
•The cigar lighter gets extremely hot. Handle it with caution and
do not allow it to be used by children to avoid the risk of fire or
burns. Always check that the cigar lighter has switched off.
•Only accessories with a maximum power of 180 W (maximum
absorption 15 A) can be connected to the socket.
•Never travel with the glove compartment open: it could injure
the passenger in the event of a crash.
•On both sides of the passenger side sun visor there is a label
remembering that it is compulsory to deactivate the airbags if a
rearward facing child restraint system is fitted.
Always comply with the instructions on the label.10) SUNROOF – ELECTRIC SOFT TOP
ELECTRIC WINDOWS
When leaving the car, always remove the key from the ignition
device to avoid the risk of injury to the vehicle occupants due to
accidental operation of these devices: improper use can be
dangerous. Before and during operation, always check that
nobody is exposed to the risk of being injured either directly by
the moving window or through objects getting
caught or hit by it.
11) SOFT TOP
•Keep hands away from the soft top mechanism while opening
and closing the soft top or if the soft top stops in a position before
the cycle is completed to prevent damage and injury.
•Keep children away from the area in which the top is folding
during opening or closing operations.
12) DOORS
Before opening a door, ensure that you can do it in conditions of
safety. Open the doors only when the vehicle is stationary.
13) LUGGAGE COMPARTMENT
•Never exceed the maximum allowed load in the luggage
compartment, see chapter “Technical specifications”. Also make
sure that the objects you place in the luggage compartment have
been properly secured, to avoid them from being thrown forward
consequent to sudden braking and injuring your passengers.
•Do not drive with the tailgate open as exhaust fumes may enter
the vehicle.
•If you are travelling in areas with few filling stations and you
want to transport fuel in a spare tank, comply with the law by
using only an approved, suitably secured tank. In the event of a
collision the fire risk is increased all the same.

189(CONTINUES)
PERSONAL SAFETY
(CONTINUED)
•When opening the tailgate, take care not to hit possible
objects on the roof rack.
•Make sure the backrests are properly secured at both sides
to prevent them from moving forward, in the event of sharp
braking, with possible impact with of the passengers.
14) ROOF RACK/SKI RACK
•Fully comply with the regulations in force concerning
maximum clearance.
•Never exceed the maximum permitted loads; see chapter
“Technical specifications”.
•Evenly distribute the load and take into account, when
driving, the increased responsiveness of the vehicle to side
wind. After travelling for a few kilometres, check to ensure that
the fixing screws for the attachments are well tightened.
•Before driving, make sure that the transversal bars have been
fitted properly.
15) ABS SYSTEM – ESC SYSTEM
•The ABS gets the most from the available grip, but it cannot
improve it; you should therefore take every care when driving on
slippery surfaces and not take unnecessary risks.
•When the ABS cuts in and you feel the brake pedal pulsating,
do not remove your foot, but keep the pedal pushed down; in
doing so you, will stop in the shortest distance possible under
the road conditions at the time.
•If the ABS system intervenes, this indicates that the traction of
the tyres on the road is nearing its limit. You must slow down to
a speed compatible with the available traction.
• To obtain the maximum efficiency of the braking system, a
bedding-in period of about 500 km is needed: during this period
it is better to avoid sharp, repeated and prolonged braking. • The ABS, ESC and ASR systems cannot overrule the natural
laws of physics, and cannot increase the grip available according
to the condition of the road.
• The ABS, ESC, ASR and HBA systems cannot prevent
accidents, including those due to excessive speed on corners,
driving on low-grip surfaces or aquaplaning.
• The capability of the ABS, ESC, ASR and HBA systems must
never be tested irresponsibly and dangerously, in such a way as
to compromise personal safety and the safety of others.
•When the Mechanical Brake Assist intervenes, noises may be
heard from the system.
This is normal. In any case, while braking keep the brake pedal
firmly depressed.
•If only the
xwarning light on the instrument panel lights up
(together with a message in the multifunction display, for
versions/markets, where provided) stop the vehicle immediately
and contact the nearest Fiat Dealership. Fluid leaking from the
hydraulic system will compromise the operation of the braking
system, whether it is of the conventional type or with ABS.
•Do not take unnecessary risks, even if your vehicle is fitted with
the ESC and ASR systems.
Your driving style must always be suited to the road conditions,
visibility and traffic. The driver is always responsible for road
safety.
•If the space-saver wheel (where provided) is used, the ABS,
ASR and ESC systems keep operating.
Always remember that the space-saver wheel, being smaller than
the original wheel provides less grip.
•For correct operation of the ABS, ESC and ASR systems, the
tyres must absolutely be of the same brand and type on all
wheels, in perfect conditions and, above all, of type, brand and
size specified.

IMPORTANT INFORMATION AND RECOMMENDATIONS
190(CONTINUES)
PERSONAL SAFETY
(CONTINUED)
•The HH system is not a parking brake, therefore do not leave
the vehicle without activating the handbrake, switching off the
engine, and engaging first gear, with the vehicle parked in safe
conditions.
•There may be situations on small gradients
(less than 8%), with car laden or a trailer attached to it (where
provided), in which the HH system may not activate, causing a
slight reversing motion and increasing the risk of collision with
another vehicle or object.
The driver is, in any case, responsible for safe driving.
•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.
•The HBA system is an aid for the driver, who must always pay
full attention while driving.
The responsibility always rests with the driver.
16) ENGINE BONNET
•Before opening the bonnet, check that windscreen wiper
arm is not lifted from the windscreen.
•The bonnet may drop suddenly if the supporting rod is not
positioned correctly.
Only perform these operations when the car is stationary.
•Be careful working inside engine compartment when the
engine is hot to avoid burning yourself. Do not place your
hands near the engine fan as it may be activated even when
the key is removed. Wait until the engine has cooled.
•Be very careful not to allow scarves, neck ties and other
loose articles of clothing from touching, even accidentally, any
moving parts. This may cause the clothing to be pulled into the
part, resulting in serious injury to the wearer. •For safety reasons, the bonnet must always be properly closed
while the car is travelling. Make sure that the bonnet is properly
closed and that the lock is engaged. If you notice when driving
that the bonnet has not been properly locked, stop immediately
and close the bonnet correctly.
•Use both hands to lift the bonnet. Before lifting, check that the
windscreen wiper arms are not raised from the windscreen, that
the vehicle is stationary and that the handbrake is engaged.
17) CONTROLS
•It is absolutely forbidden to carry out any after-market operation
involving steering system or steering column modifications
(e.g. installation of anti-theft device) that could adversely affect
performance and safety, invalidate the warranty and also result in
non-compliance of the vehicle with type-approval requirements.
•Before performing any maintenance operations, always stop
the engine and remove the key from the ignition to lock the
steering column (especially when the car wheels are not touching
the ground). If this is not possible (for example if the key needs to
be turned to MAR or the engine must be running), remove the
main fuse that protects the electric power steering.
18) PARKING SENSORS
Parking manoeuvres, however, are always the driver’s
responsibility. While carrying out these manoeuvres, always make
sure that no people (especially children) or animals are in the area
concerned.
The parking sensors are used to assist the driver, who must
never allow his attention to lapse during potentially dangerous
manoeuvres, even those executed at low speeds.

IMPORTANT INFORMATION AND RECOMMENDATIONS
192
24) ISOFIX CHILD RESTRAINT SYSTEM FITTING
•Fit the child restraint system according to the instructions, which
must be included.
•Child restraint systems with ISOFIX attachments are available for
safely anchoring to the seat without using the car seat belts. For
this type of seats see paragraph “Installation of an Isofix child
restraint system” in the “Safety” chapter.
•If a Universal ISOFIX child restraint system is not fixed to all three
anchorages, it will not be able to protect the child correctly. In a
crash, the child could be seriously or fatally injured.
•Fit the child restraint system when the car is stationary. The child
restraint system is correctly fixed to the brackets when you hear the
click. Always follow the instructions for assembly, disassembly and
positioning that the manufacturer of the car seat is required
to provide with it.
•Should it be necessary to carry a child on the passenger side front
seat in a rear facing child restraint system, the passenger side front
airbag and side bag must be deactivated through the display main
menu, verifying deactivation by checking that the warning light has
switched on in the
“central part of the dashboard. Move the
passenger’s seat as far back as possible to avoid contact between
the child seat and the dashboard.
•Incorrect fitting of the child restraint system may result in an
inefficient protection system. In the event of an accident the child
restraint system may become loose and the child may be injured,
even fatally. When fitting a restraint system for newborns or children,
strictly comply with the instructions provided by the Manufacturer.
•When the child restraint system is not used, secure it with the seat
belt or with the ISOFIX anchorages, or remove it from the vehicle.
Do not leave it unsecured inside the passenger compartment. In this
way, in the case of sudden braking or an accident, it will not cause
injuries to the occupants.
(CONTINUES)
PERSONAL SAFETY
(CONTINUED)
•If the belt has been sharply pulled, for example as the result
of an accident, the seat belt, together with the anchoring
devices, the anchoring device fixing screws and the
pretensioner must be completely replaced. Even if the belt
does not present any exterior signs of wear or damage, it may
have lost its restraining properties.
23) CARRYING CHILDREN SAFELY
SERIOUS DANGER: When an active passenger airbag is fitted,
DO NOT install rear facing child restraint systems on
the front seat.
Deployment of the airbag in an accident could cause fatal
injuries to the child regardless of the severity of the impact.
It is advisable to always carry children in a child restraint
system on one of the rear seats, which is the most protected
position in the event of a collision.
•If a child must be carried on the front seat in a rearward
facing child restraint system, it is compulsory to deactivate the
passenger side front airbag, making sure that it is deactivated by
checking the dedicated warning light on the instrument panel (see
“Passenger front airbag” in the “Front airbags” section). Move the
passenger’s seat as far back as possible to avoid contact
between the child seat and the dashboard.
•On both sides of the sun visor there is a label advising that it is
compulsory to deactivate the airbag if a rearward facing child
restraint system is fitted.
Always comply with the instructions on the passenger’s side sun
visor (see the “Front airbag” paragraph).
•Do not move the front or rear seat if a child is seated on it or on
the dedicated child restraint system.

193
•After installing a child restraint system, do not move the seat:
always remove the child restraint system before making any
adjustment.
•Always make sure that the chest section of the seat belt does
not pass under the arms or behind the back of the child. In the
event of an accident the seat belt will not be able to secure the
child, with the risk of injury, including fatal injury. Therefore the
child must always wear the seat belt correctly.
•Do not use the same lower anchorage to install more than one
child restraint system.
25) AIR BAG
•Do not apply stickers or other objects on the steering wheel,
on the dashboard in the passenger side airbag area, on the
side upholstery on the roof and on the seats. Never put
objects (e.g. mobile phones) on the passenger’s
side of the dashboard since they could interfere with proper
airbag inflation and also cause serious injury to the
passengers.
• SERIOUS DANGER: When there is an active passenger
airbag, DO NOT install rearward facing child restraint systems
on the front seat.
Deployment of the airbag in an accident could cause fatal
injuries to the child regardless of the severity of the impact. It is
advisable to always carry children in a child restraint system on
the rear seat, which is the most protected position in the event
of a collision.
•When an active passenger airbag is fitted, DO NOT install
rear facing child restraint systems on the front seat.
Deployment of the airbag in an accident could cause fatal
injuries to the child regardless of the severity of the impact. •Do not rest your head, arms or elbows on the door, windows
or the area in which the window bag is located to avoid possible
injury during airbag inflation. Never lean your head,
arms or elbows out of the window.
•If when turning the key to MAR the warning light
¬does not
turn on or if it stays on when travelling, there could be a failure in
the safety systems; in this event airbags or pretensioners may not
be deployed in the event of impact or, in a lower number of
cases, they deploy accidentally.
Contact a Fiat Dealership immediately to have the system
checked.
•Do not cover the front seat backrests with extra covers if they
are equipped with side bags.
•Do not travel carrying objects in your lap, in front of your chest
or between your lips (pipe, pencils, etc.):
they could cause severe injury if the airbag is deployed.
•Always drive keeping your hands on the steering wheel rim so
the airbag can inflate freely if necessary. Do not drive with your
body bent forward. Keep your back straight against the backrest.
•If the car has been stolen or in the case of attempt to steal it, if
it has been subjected to vandalism or floods, have the airbag
system checked by a Fiat Dealership.
•The airbags may also be deployed when the car is not moving,
if the key is in the ignition and turned to MAR or when the engine
is off, if the car is hit by another moving vehicle. Therefore, even if
the vehicle is stationary, when an active front passenger airbag is
fitted, DO NOT install rearward facing child restraint systems on
the front passenger seat.
Deployment of the airbag following an impact could cause fatal
injuries to the child.

IMPORTANT INFORMATION AND RECOMMENDATIONS
198
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.

IMPORTANT INFORMATION AND RECOMMENDATIONS
202
1) KEYS AND CODE CARD
•The electronic components inside the key may be damaged if
the key is subjected to strong shocks. In order to ensure
complete efficiency of the electronic devices inside the keys,
they should never be exposed to direct sunlight.
•All the keys and the CODE card must be handed over to the
new owner when selling the car.
2) SEATS
•The fabric upholstery of the seats has been designed to
withstand long-term wear deriving from normal use of the car.
Some precautions are however required. Avoid prolonged and/or
excessive rubbing against clothing accessories such as metal
buckles and Velcro strips which, by applying a high pressure on
the fabric in a small area, could cause it to break, thereby
damaging the upholstery.
•Before tilting the backrest, remove any objects on the seat
cushion.
3) CLIMATE CONTROL SYSTEM
Never use R12 coolant, which is not compatible with climate
control system components.
4) WINDSCREEN AND REAR WINDOW WIPER
•Do not use the windscreen or rear window wiper to remove
layers of snow or ice from the windscreen. In such conditions,
the windscreen and rear window wiper may be subjected to
excessive stress and the motor cut-out switch, which prevents
operation for a few seconds, may intervene. If operation is not restored, contact a Fiat Dealership.
•Do not operate the windscreen wiper with the blades lifted from
the windscreen:
• Do not activate the rain sensor or the rearscreen wiper when
washing the car in an automatic car wash.
• Make sure that the device is turned off if there is ice on the
windscreen.
5) SUNROOF
•Use the sunroof only at “spoiler” position if a transverse roof
rack is fitted.
•Do not open the sunroof if there is snow or ice on it: you may
damage it.
•Be careful not to hit objects on the storage shelf when you
open the tailgate.
6) SOFT TOP
•Never open the top in presence of snow or ice to prevent
damage.
•Do not place objects on the rear window shelf to prevent
damage while the top is closing.
•Loads may not be secured on the roof.
•Bird droppings must be washed off immediately and thoroughly
as the acid they contain is particularly aggressive.
•Never use high-pressure washing systems.
•When using steam washers or high-pressure water washers,
maintain a suitable distance and do not exceed a maximum
temperature of 60°C.
Damage, alterations and water infiltrations may occur if the
distance is too small.
•If a water jet is used, direct away from the edges of the fabric
and the rear window frame to prevent water infiltrations.
