Window demisting
In the event of considerable external
moisture and/or rain and/or large differ-
ences in temperature inside and outside
the passenger compartment, perform the
following preventive window demisting
procedure:
❒turn knob A to red section;
❒turn air internal recirculation off by
pressing button D so the button LED
goes out;
❒turn knob C to -or to ®if the win-
dows do not demist;
❒turn knob B to 2ndspeed.
IMPORTANT The climate control system
is very useful to prevent the windows
misting up in the presence of high humid-
ity since it dries the air introduced into the
passenger compartment. HEATED REAR WINDSCREEN

LOOKING AFTER THE SYSTEM
Run the climate control system for at least
10 minutes every month during the win-
ter. Have the system inspected at a Fiat
Dealership before the summer.
The system uses R134a re-
frigerant fluid which does not
harm the environment in the
event of accidental leakage.
Never use R12 fluid, which is not com-
patible with the system components.IMPORTANT The air internal recircula-
tion system makes it possible to reach the
required heating or cooling conditions
faster.
Do not use the air internal recirculation
function on rainy/cold days as it would
considerably increase the possibility of the
windows misting up.
INTERNAL AIR INTERNAL
RECIRCULATION ACTIVATION
Press
•so that the button LED is on.
It is advisable to switch the internal air in-
ternal recirculation on while standing in
queues or in tunnels to prevent the in-
troduction of polluted air. Do not use the
function for a long time, particularly if
there are many passengers on board, to
prevent the windows from misting up.

FAILURE INDICATIONS
Any failure of the electric power steering
system is indicated by instrument panel
warning light
gcoming on together with
a message on the multifunction display (for
versions/markets, where provided) (see
section “Warning lights and messages”).
In the event of electric power steering sys-
tem failure, the car can be driven with me-
chanical steering.
IMPORTANT In some circumstances, fac-
tors independent of the electric power
steering could cause the
gwarning light
in the instrument panel to come on.
In this case, stop the car immediately,
switch off the engine for about 20 seconds
and then restart the car. If the warning
light
gis still on, along with the message
on the multifunction display (for ver-
sions/markets, where provided), contact
a Fiat Dealership. IMPORTANT The steering may become
stiffer during parking manoeuvres that re-
quire a lot of turns of the wheel. This is
normal and is caused by the electric con-
trol motor overheating protection system.
No repairs are needed. The power steer-
ing system will start working properly
again the next time the car is used.
It is absolutely forbidden to
carry out any after-market
operation involving steering system or
steering column modifications (e.g. in-
stallation of anti-theft device) that
could badly affect performance and
safety, invalidate the warranty and
also result in the car failing to com-
ply with regulations.
WARNING
Before servicing the car,
switch off the engine and re-
move the key from the ignition to ac-
tivate the steering lock. This is espe-
cially important 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 en-
gine must be running), remove the
main fuse that protects the electric
power steering.
WARNING

PRETENSIONERS
To increase the efficiency of the seat belts,
the car is fitted with front pretensioners.
These devices, in the event of a violent
crash, rewind the seat belts by a few cen-
timetres. In this way, they ensure that the
seat belt adheres perfectly to the wearer
before the restraining action begins.
The seat belt reel locks to indicate that the
pretensioners have intervened; the seat
belt cannot be drawn back up even when
guiding it manually.
IMPORTANT To obtain the highest de-
gree of protection from the action of the
pretensioning device, wear the seat belt
tight to the chest and pelvis.
A slight amount of smoke may be detect-
ed during operation of the pretensioners.
This smoke is not harmful and does not
indicate a fire.
The pretensioner does not require any
maintenance or lubrication.
Anything that modifies its original condi-
tions invalidates its efficiency.
If, due to unusual natural events (floods,
sea storms, etc.), the device has been
affected by water and mud, it must be
replaced.LOAD LIMITERS
To increase passenger safety, the front
seat belt reels contain a load limiter which
controls the force acting on the chest and
shoulders during the belt restraining ac-
tion in the event of a head-on collision.

The pretensioner can be
used only once. Go to a Fiat
Dealership to have it replaced after
it has been deployed.
WARNING
Operations which lead to
knocks, vibrations or lo-
calised heating (over 100 °C
for a maximum of 6 hours) in
the area around the pretensioners may
cause damage or trigger them. Contact
a Fiat Dealership for any assistance.

tem and irregular engine op-
eration. If warning light
ccomes on
(with a message on the display on some
versions), go to a Fiat Dealership as
soon as possible to have the system
bled. Water may have entered the tank
if this appears immediately after refu-
elling: if this happens, switch the engine
off immediately and contact a Fiat
Dealership.

IMPORTANT INFORMATION:
The sealing fluid of the quick tyre repair
kit is effective with external temperatures
of between −20 °C and +50 °C.
The sealant fluid has an expiry date.
Do not operate the com-
pressor for longer than
20 minutes at a time. Risk of over-
heating. The quick repair kit is not
suitable for definitive repairs, so
the tyres repaired may be used only
temporarily.
WARNING
In the event of a puncture
caused by foreign bodies, it is
possible to repair tyres show-
ing holes on the track or
shoulder of up to 4 mm in diameter.
It is not possible to repair
damage to the tyre sidewall.
Do not use the quick repair kit if the
tyre is damaged as a result of driving
with it deflated.
WARNING
A repair is not possible if
the wheel rim is damaged
(groove is deformed, causing air to es-
cape). Do not remove foreign bodies
(screws or nails) from the tyre.

BLADES
Regularly clean the rubber part using ap-
propriate products; TUTELA PRO-
FESSIONAL SC35 is recommended.
Replace the blades if the rubber edge is
misshapen or worn. In any event, it is ad-
visable to replace them approximately
once a year.
A few simple precautions can reduce the
possibility of damage to the blades:
❒make sure that the rubber part is not
frozen to the windscreen in sub-zero
temperatures. Use an antifreeze prod-
uct to release it if required;
❒remove any snow from the glass: in ad-
dition to protecting the blades, this pre-
vents the electric motor from over-
heating;
❒do not operate the windscreen wipers
on dry glass.
Driving with worn wiper
blades is a serious hazard,
because visibility is reduced in bad
weather.
WARNING
RUBBER TUBES
As far as the brake system and fuel rubber
hoses are concerned, stick closely to the
“Scheduled Servicing Plan” in this section.
Ozone, high temperatures and a pro-
longed lack of fluid in the system may
cause hardening and cracking of the tubes,
which could result in leaks. Careful in-
spections are therefore necessary.If the pressure is too low, the
tyre will overheat and could
be seriously damaged.
WARNING
Avoid switching the tyres
from the right side of the ve-
hicle to the left side and vice versa.
WARNING
Do not re-spray alloy wheel
rims at temperatures higher
than 150 °C. The mechanical char-
acteristics of the wheels may be
compromised.
