IGNITION
The key can be turned to 3 different po-
sitions fig. 9:
❒STOP: engine off, key can be extract-
ed, steering locked. Some electrical de-
vices (e.g. sound system, central door
locking system, etc.) can function.
❒MAR: driving position. All electricaldevices can function.
❒AVV: engine starting (temporary posi- tion).
The ignition device is fitted with an elec-
tronic safety system that, in the event the
engine fails to start, turns back the ignition
key to STOP before repeating the start-
ing operation. STEERING LOCK
Engagement
When the key is in position
STOP, re-
move it and turn the steering wheel until
it locks.
Disengagement
Rock the steering wheel slightly as you
turn the key to MAR.
If the ignition device has
been tampered with (e.g. an
attempted theft), have it checked
over by a Fiat Dealership as soon as
possible.
WARNING
Always remove the key when
you leave your car to pre-
vent someone from accidentally op-
erating the controls. Remember to
engage the handbrake. Engage first
gear if the car is parked uphill or re-
verse if the car is parked downhill.
Never leave children unattended in
the car.
WARNING
fig. 9F0M0608m
Never extract the key while
the vehicle is moving. The
steering wheel would lock automati-
cally as soon as it is turned. This also
applies to when the car is towed.
WARNING
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 not complying
with regulations.

ESP SYSTEM (Electronic
Stability Program)
(for versions/markets, where provided)
This is an electronic system that controls
car stability in the event of tyre grip loss,
helping to maintain directional control.
The ESP system is therefore particularly
useful when road surface grip changes.
In addition to the ESP system, ASR system
and Hill Holder, the MSR system (adjusting
the engine braking torque) and the HBA
system (improving the braking force dur-
ing emergency braking) are also provided
(for versions/markets, where provided).
SYSTEM INTERVENTION
This is signalled by the flashing of warn-
ing light
áon the instrument panel, to in-
form the driver that the car is in critical
stability and grip conditions.
When the ABS cuts in and
you feel the brake pedal pul-
sating, do not remove your foot, but
keep the pedal pushed down; in do-
ing so you, will stop in the shortest
distance possible under the road con-
ditions at the time.
WARNINGEBD failure
This is indicated by the
>and xwarn-
ing lights on the instrument panel togeth-
er with the dedicated message on the mul-
tifunction display (for versions/markets,
where provided) coming on (see “Warn-
ing lights and messages” section).
In this case, the rear wheels may sudden-
ly lock and the vehicle may swerve when
braking sharply. Drive carefully to the
nearest Fiat Dealership to have the system
checked.
If only the xwarning light
on the instrument panel
lights up (together with a message in
the multifunction display, for ver-
sions/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.

CONTROLS
AND DEVICES
Do not take unnecessary
risks, even if your vehicle is
fitted with this system. Your driving
style must always be suited to the
road conditions, visibility and traffic.
The driver is always responsible for
road safety.
WARNING
For correct operation of the ASR system,
the tyres must be of the same brand and
type on all wheels, in perfect conditions
and, above all, of the type, brand and size
recommended.
FAILURE INDICATIONS
In the event of a failure, the ASR system
will be automatically switched off and
warning light
áwill appear permanently
on the instrument panel along with a mes-
sage on the multifunction display (for ver-
sions/markets, where provided) (see
“Warning lights and messages”). In this
case, contact a Fiat Dealership as soon as
possible.
EOBD SYSTEM
The EOBD (European On Board Diagno-
sis) system allows continuous diagnostics
of the emission-related components of the
car.
It also alerts the driver, by turning on the
Uwarning light on the instrument panel
(together with a relevant message in the
multifunction display, for versions/mar-
kets, where provided) (see “Warning
lights and messages” section), when these
components are no longer in peak con-
dition.
The goal of the system is to:
❒keep the system efficiency under con- trol;
❒warn when a fault causes emissions lev- els to increase;
❒warn of the need to replace non-per-forming components.
The system also has a connector that can
be interfaced with appropriate equipment,
which makes it possible to read the er-
ror codes stored in the control unit, to-
gether with a series of specific parameters
for engine operation and diagnosis. This
check can also be carried out by traffic
authorities. IMPORTANT After resolving the prob-
lem, to check the system completely, Fi-
at Dealerships are obliged to run a bench
test and, if necessary, road tests which
may call for a long journey.
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 permanently or
flashes (along with a message in the
multifunction display for versions/mar -
kets, where provided), contact a Fiat
Dealership as soon as possible. The
operation of the Uwarning light may
be checked by traffic police using ap-
propriate equipment. Follow the laws
in force in the country where you are
driving.

CAR INACTIVITY
If the car is to be left inactive for longer
than a month, the following precautions
should be observed:
❒park the car in covered, dry and, if pos- sible, well-ventilated premises;
❒engage a gear;
❒check that the handbrake is engaged;
❒disconnect the clip for the negative bat-tery terminal and check battery charge.
Repeat this check once every three
months during storage. Recharge the
battery if the indicator is dark and the
middle area is not green;
❒clean and protect the painted parts us-ing protective wax;
❒clean and protect the shiny metal partsusing special compounds readily avail-
able;
❒sprinkle talcum powder on the rubberwindscreen and rear window wiper
blades and lift them off the glass;
❒open the windows slightly;
❒cover the car with a fabric or perfo-rated plastic sheet. Do not use compact
plastic sheets which do not allow hu-
midity to evaporate from the surface of
the car;
❒inflate tyres to a pressure of +0.5 barabove the normal specified pressure
and check regularly;
❒if you don’t disconnect the battery fromthe electrical system, check its charge
every month and recharge it if the in-
dicator shows a dark colour without
the central green area;
❒do not drain the engine cooling system.
IMPORTANT Where relevant, switch off
the car alarm with the remote control.
Keep your speed down when snow chains are fitted – do
not exceed 50 km/h. Avoid
potholes, steps and pave-
ments and also avoid driving
for long distances on roads
not covered with snow to avoid dam-
aging the car and the road surface.

AIRBAG FAULT
(red)
When the ignition key is moved to MAR,
the warning light turns on but should go
off after a few seconds.
The warning light stays on constantly if
there is a failure in the airbag system.
A specific message is displayed on certain
versions.
¬If the warning light ¬does
not turn on when turning the
key to MAR or stays on during car
travel, there may be a failure in the
restraint systems. If this is the case,
the airbags or pretensioners may not
be deployed in an accident or, in a
minor number of cases, they may be
deployed incorrectly. Contact a Fiat
Dealership immediately to have the
system checked before driving off.
WARNING
A problem with the warning
light
¬(light off) is indicat-
ed by the warning light
“, which in-
dicates the front passenger airbag is
deactivated, flashing for more than
the usual four seconds.
WARNING
OVERHEATED ENGINE
COOLANT (red)
When the ignition key is moved to MAR,
the warning light turns on but should go
off after a few seconds.
The warning light turns on when the en-
gine is overheated.
If the warning light comes on, proceed as
follows:
❒ when driving normally: stop the car,
switch off the engine and check that the
coolant level in the reservoir is not be-
low the MIN mark. If it is, wait for the
engine to cool down then slowly and
carefully open the cap, top up with
coolant and check that the level is be-
tween the MIN and MAX marks on the
reservoir. Also check visually for any
fluid leaks. If, when restarting, the warn-
ing light comes on again, contact a Fiat
Dealership.

When the ignition key is turned to MAR
(ON), the warning light switches on and
should go out as soon as the engine is
started.
Low engine oil pressure
The warning light turns on and stays on
constantly (for versions/markets, where
provided) along with the message on the
display when the system detects that en-
gine oil pressure is low.
v
If the warning light vturns on when the vehicle is
travelling (on certain versions to-
gether with the message on the dis-
play) stop the engine immediately
and contact a Fiat Dealership.
WARNING
❒ if the vehicle is used under de-
manding conditions (e.g. towing
trailers uphill or fully loaded): slow
down and, if the light stays on, stop the
car. Stop for 2 or 3 minutes with the
engine running and slightly accelerated
to assist better coolant circulation.
Then switch the engine off. Check cor-
rect fluid level as described above.
IMPORTANT On particularly demanding
journeys, it is advisable to keep the engine
on and slightly accelerated for a few min-
utes before switching it off.
A specific message is displayed on certain
versions.
LOW BATTERY
CHARGE (red)
When the ignition key is moved to MAR,
the warning light turns on but should go
out as soon as the engine is started (with
the engine idling, a brief delay can be ex-
pected).
If the warning light comes on, either per-
manently or intermittently, contact a Fiat
Dealership immediately.
w
Exhausted engine oil
(only Multijet versions with DPF)
The warning light will flash and a specific
message will appear on the display (for
versions/markets, where provided). The
warning light may flash in the following
ways, depending on the version:
– for 1 minute every two hours;
– for 3 minute cycles with the warning
light off for intervals of 5 seconds until oil
is changed.
After the initial warning, each time the en-
gine is started up, the warning light will
continue to flash in the above mentioned
modes, until the oil is changed. A specific
message will appear on the display (for
versions/markets, where provided) in ad-
dition to the warning light.
If the warning light flashes, this does not
mean that the car is defective but simply
informs the driver that it is now necessary
to change the oil as a result of regular ve-
hicle use.
Note that engine oil is exhausted faster
under the following circumstances:
– use of the vehicle prevalently for city dri-
ving, requiring more frequent regenera-
tion of DPF
– use of the vehicle for short drives, in
which the engine does not have time to
reach its regular operating temperature
– repeated interruption of the regenera-
tion process, signalled by the DPF warn-
ing light coming on.

LOW ENGINE OIL
LEVEL (red)
(for versions/markets, where
provided)
When turning the ignition key to MAR,
the warning light turns on but it should go
off after a few seconds.
This warning light where provided comes
on when the engine oil level falls below the
minimum recommended value. Restore
the correct engine oil level (see “Check-
ing fluid levels” in the “Servicing and care”
section).
A specific message is displayed on certain
versions.
kExhausted engine oil should
be replaced as soon as pos-
sible after the warning light comes on,
never more than 500 km after the
warning light first comes on. Failure
to change the oil within the first 500
km may result in severe damage to
the engine and will result in forfeiture
of the warranty. Remember that
when the warning light flashes, it does
not mean that the level of engine oil
is low, so if the light flashes you must
not top up.
WARNING
For versions/markets, where
provided:
the
vwarning light turns on and flash-
es along with the message on the display
(if applied) when the system detects that
the engine oil is exhausted. The flashing of
the warning light should not be considered
as a fault, rather simply informs the driver
that oil needs to be changed after a stan-
dard period of car utilisation. If the oil is
not changed, when reaching a second de-
terioration threshold, also the warning
light
Uswitches on in the instrument
panel and the engine operation is limited
at 3000 rpm.
If the oil is still not changed, when reaching
a third deterioration threshold, the engine
is limited at 1500 rpm to avoid damage.
WARNING! To avoid dam-
aging the engine it is recom-
mended to change the en-
gine oil when the warning light
v
flashes. Contact a Fiat Dealership.
