ALARM
(where provided)
WHEN THE ALARM
IS TRIGGERED
The alarm comes into action in the fol-
lowing cases:
❒unlawful opening of one of the doors,
bonnet or boot (perimetral protec-
tion);
❒attempt to start the engine with unau-
thorised key;
❒battery cable cutting;
❒presence of moving bodies in the pas-
senger’s compartment (volumetric
protection);
❒abnormal raising/sloping of the car.
Depending on the markets, the cutting in
of the alarm causes operation of the siren
and direction indicators (for about 26 sec-
onds). The ways of operating and the num-
ber of cycles may vary depending on the
markets.
A maximum number of sound/sight cycles
is however envisaged.

If the doors, bonnet and boot are shut
correctly and the warning “beep” is re-
peated, the system self-diagnostics has de-
tected a system operating fault. It is there-
fore necessary to contact a Fiat Dealer-
ship.
IMPORTANT Operating a door with the
metal insert of the key will not activate the
alarm.
IMPORTANT The alarm is built in com-
pliance with the law and regulations of the
different destination countries.

sitions fig. 17:
❒OFF: engine off, key can be removed,
steering column locked. Certain elec-
trical devices (e.g.: sound system, pow-
er windows…) can work.
❒ON: driving position. All electrical de-
vices are powered.
❒START: engine starting.
The ignition switch is fitted with an elec-
tronic safety system that, in the event the
engine is not started, turns back the igni-
tion key to OFFbefore repeating the
starting operation.

TO INCREASE THE MEMORISED
SPEED
The speed memorised can be increased in
two ways:
❒pressing the accelerator and then
memorising the new speed reached;
or
❒moving the stalk upwards (+).
Each operation of the stalk will corre-
spond to a slight increase in speed (about
1 km/h), while keeping the stalk upwards
will correspond to a continuous speed in-
crease.
TO REDUCE MEMORISED
SPEED
The speed memorised can be increased in
two ways:
❒disengaging the device and then mem-
orising the new speed;
or
❒moving the stalk downwards (–) until
reaching the new speed which will be
memorised automatically.
Each operation of the stalk will corre-
spond to a slight reduction in speed (about
1 km/h), while keeping the stalk down-
wards will correspond to a continuous
speed reduction.DEVICE DISENGAGEMENT
The device can be disengaged in the fol-
lowing ways:
❒turning the knurled ring Ato OFF;
❒turning the engine off;
❒pressing the brake pedal or engaging
the hand brake;
❒pressing the clutch pedal;
❒shifting gear with automatic transmis-
sion in sequential mode;
❒with car speed below the preset lim-
it;
❒pressing the accelerator pedal; in this
case the system is not really disen-
gaged but the request for acceleration
takes priority over the system. The
cruise control is however active and it
will not be necessary to press button
RES to resume previous conditions
after ending acceleration.The device is automatically deactivated in
one of the following cases:
❒ABS or ESP system cut-in;
❒system failure.
When travelling with the de-
vice on, never set the
gearshift lever to neutral.
WARNING
In the event of device mal-
function or failure, turn the
knurled ring A to OFF and contact a
Fiat Dealership after checking the
protection fuse integrity.

TO CLOSE THE BONNET fig. 114
Proceed as follows:
❒hold the bonnet up with one hand and
with the other remove rod Cfrom re-
cess Eand fit it back into its catch D;
❒lower the bonnet at approx. 20 cen-
timetres from the engine compart-
ment and then let it drop, ensuring
that it is fully closed and not just held
in position by the safety catch. If the
bonnet does not close properly, do
not push it down but open it again and
repeat the above procedure.
IMPORTANT Always check that the bon-
net is closed properly to avoid its opening
while the car is travelling.
fig. 112F0L0048m
fig. 113F0L0049m
fig. 114F0L0116m
For safety reasons the bon-
net must be closed properly
to avoid its opening while the car is
travelling. Therefore, always check it
is properly closed and the catch en-
gaged. Should you notice that the
catch is not perfectly engaged when
travelling, stop the car immediately
and close the bonnet.
WARNING
If the supporting rod is not
positioned correctly the bon-
net may fall violently.
WARNING
Carry out operations only
when the car is stationary.

AND CONTROLS
When travelling on snowy roads with
snow chains, it may be helpful to turn the
ASR off: in fact, in these conditions, slip-
ping of the driving wheels when moving off
makes it possible to obtain better drive.FAILURE INDICATIONS
In the event of malfunctioning, the ASR
system is automatically disconnected and
the warning light
áwill come on with
fixed light on the instrument together with
the message on the display (see section
“Warning lights and messages”). In this
case contact Fiat Dealership as soon as
possible.
EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the car correlated with
emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument pan-
el (together with the message on the dis-
play) (see section “Warning lights and
messages”), when these conditions are no
longer in peak conditions.
The objective is:
❒to keep the system efficiency under
control;
❒warn when a fault causes emissions
levels to increase;
❒warn of the need to replace deterio-
rated components.
The system also has a diagnostic connec-
tor that can be interfaced with appropri-
ate tools, which makes it possible to read
the error codes stored in the control unit,
together with a series of specific parame-
ters for engine operation and diagnosis.
This check can also be carried out by the
traffic police.
The performance of the sys-
tem, in terms of active safe-
ty should not induce the driver to take
pointless and unnecessary risks. The
style of driving must in any case al-
ways be adapted to the conditions of
the road surface, visibility an traffic.
Road safety is always the driver’s re-
sponsibility.
WARNING
For correct operation of the
ASR system, the tyres must
absolutely be of the same brand and
type on all wheels, in perfect condi-
tions and, above all, of type, brand
and size specified.

IMPORTANT NOTES ABOUT
THE T.P.M.S. SYSTEM
Failure indications will not be stored and
therefore will not be displayed when turn-
ing the engine off and on again. If failure
persists, the control unit will send warn-
ing indications to the instrument panel on-
ly after a few seconds when the car is
moving.
IMPORTANT T.P.M.S. system cannot in-
dicate sudden tyre pressure drops (e.g.:
tyre burst). In this event, brake the car
cautiously and avoid sudden steering.
IMPORTANT Replacing standard tyres
with winter tyres and vice versa involves
T.P.M.S. system set-up that shall be per-
formed at Fiat Dealerships only.
IMPORTANT The T.P.M.S. system re-
quires special equipment. Consult Fiat
Dealership to know what type of acces-
sories are compatible with the system
(wheels, wheel caps, etc.). Using other ac-
cessories could cause system malfunc-
tioning.IMPORTANT Tyre pressure could change
according to outside temperature. For this
reason the T.P.M.S. system could tem-
porarily indicate low tyre pressure. In this
event check pressure with cold tyres and
restore proper inflation values if required.
IMPORTANT If the car is fitted with
T.P.M.S. system, tyre and/or rim removal
and refitting operations involve special
precautions; to prevent damages or wrong
sensor refitting, contact Fiat Dealership to
have tyre and/or rim changed.
IMPORTANT If the car is fitted with
T.P.M.S. system, when changing a tyre,
change also the rubber seal of the valve.
Contact a Fiat Dealership.
IMPORTANT Strong radiofrequency
noise may inhibit regular TPMS system op-
eration; in this event, a dedicated message
will be displayed to warn the driver. This
message will disappear automatically as
soon as noise disappears.SOUND SYSTEM
(where provided)
For the operation of the radio with
CD/MP3 CD (where provided), read the
instructions for use given in the Supple-
ment attached to the Owner Handbook.
Sound system (where provided)
The system includes:
❒2 tweeters (power 40W max. each),
located on front doors;
❒2 mid-woofers, (diameter 165 mm,
power 40W max. each), located on
front doors;
❒2 rear full-range speakers, (diameter
165 mm, power 40W max. each), lo-
cated on rear doors.

GENERAL WARNINGS
❒When parking, take the utmost care
to obstacles that may be set above or
under the sensors.
❒Objects set close to the car, under
certain circumstances are not detect-
ed and could therefore cause damages
to the car or be damaged.
❒Indications sent by the sensors can be
altered by dirt, snow or ice deposit-
ed on the sensors or by ultrasound
systems (e.g.: truck pneumatic brakes
or pneumatic hammers) set nearby the
car.
AT THE FILLING
STATION
PETROL ENGINES
Use only unleaded petrol.
To prevent errors, the diameter of the fu-
el tank filler is too small to introduce a lead
petrol pump filler. Use petrol with a rat-
ed octane number (R.O.N.) not lower
than 95.
IMPORTANT An inefficient catalyst leads
to harmful exhaust emissions, thus con-
tributing to air pollution.
IMPORTANT Never use leaded petrol,
even in small amount or in an emergency,
as this would damage the catalyst beyond
repair. For proper operation, the
parking sensors shall always
be clean from mud, dirt, snow
or ice. When cleaning the sen-
sors, take the utmost care to prevent
their damaging; do not use therefore
dry or rough clothes. Sensors shall be
washed with clean water and car de-
tergent, if required.
Parking manoeuvres howev-
er are always under the dri-
ver’s responsibility that shall always
check the absence of people (spe-
cially children) or animals in the ma-
noeuvre space. This system is just a
help for the driver but she/he shall
never reduce attention during dan-
gerous manoeuvres even if performed
at low speed.

GENERAL WARNINGS
If when turning the ignition
key to ON, the warning light
ûdoes not turn on or if it stays on
when travelling (together with the
message on the display) there could
be a failure in safety systems; in this
event air bags or pretensioners could
not trigger in case of impact or, in a
minor number of cases, they could
trigger accidentally. Contact Fiat
Dealership immediately to have the
system checked.
WARNING
Do not cover the backrest of
front and rear seats with
trims or covers that are not suitable
to be used with side bags.
WARNING
Never travel with objects on
your lap, in front of your
chest or with a pipe, pencil, etc. be-
tween your lips; injury may result in
the event of the air bag being trig-
gered.
WARNING
Always keep your hands on
the steering wheel rim when
driving, so that if the air bag is trig-
gered, it can inflate without meeting
any obstacles which could cause seri-
ous harm to you. Do not drive with the
body bent forwards, keep the seat
back rest in the erect position and lean
your back well against it.
WARNING
If the car has been stolen or
an attempt to steal it has
been made, if it has been subjected to
vandals or floods, have the air bag
system checked by Fiat Dealership.
WARNING
Remember that with the key
fitted into the ignition device
even if the engine is not running, the
air bags may be triggered on a sta-
tionary car if it is bumped by anoth-
er moving car. Therefore, never seat
children on the front seat even when
the car is stationary. On the other
hand remember that if the key is not
fitted into the ignition device, no safe-
ty system (air bags or pretensioners)
is triggered in the event of an impact;
in this case, failure to come into ac-
tion cannot be considered as a sign
that the system is not working prop-
erly.
WARNING

Roof rack/ski rack
Remove the roof rack or the ski rack from
the roof as soon as they are no longer
used. These accessories lower air pene-
tration and adversely affect consumption
levels. When needing to carry particular-
ly voluminous objects, preferably use a
trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window, ad-
ditional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside
the car permits it, use the air vents where
possible.
Spoilers
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed: under
these conditions the engine warms up
much more slowly, increasing electrical
consumption and emissions. It is therefore
advisable to move off immediately, slow-
ly, avoiding high speeds. This way the en-
gine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traffic
lights or before switching off the engine.
This and also double declutching is ab-
solutely pointless on modern cars and al-
so increase consumption and pollution.
Gear selection
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance in-
creases consumption.
In the same way improper use of a high
gear increases consumption, emissions an
engine wear.CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of your
car down and lower the amount of toxic
emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service schedule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4 weeks:
if the pressure is too low, consumption
levels increase as resistance to rolling is
higher.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the car
(especially when driving in town) and its
trim greatly affects consumption and sta-
bility.
