ABS SYSTEM INTERVENTION
The driver can tell the ABS system has
come into action because the brake pedal
pulsates slightly and the system gets noisi-
er: it means that the vehicle speed should
be altered to fit the type of road surface.
If the ABS system cuts in, it
is a sign that the grip be-
tween tyre and the road surface has
reached the limit: you must slow
down to match the speed to the road
grip available.
WARNING
ABS SYSTEM
If you have never driven a vehicle with ABS
before, you should practice using the sys-
tem on slippery terrain, obviously with the
necessary safety precautions and keeping
to the Highway Code of the country you
are in. It is also a good idea to read the fol-
lowing information carefully.
The ABS system, integral with the braking
system, prevents the wheels from locking
when braking, makes the most of road grip
and gives the best control when emergency
braking under difficult road conditions.
System is completed by EBD (Electronic
Braking force Distribution), which dis-
tributes the braking action between front
and rear wheels.
IMPORTANT To have the maximum ef-
ficiency of the braking system, it is neces-
sary a setting period of about 500 km
(with new vehicle after replacing brake
pads/discs): during this period it is better
to avoid sharp, repeated and prolonged
brakes.The ABS exploits the tyre-
road grip at the best, but it
cannot improve it; you should there-
fore take every care when driving on
slippery surfaces without taking un-
necessary risks.
WARNINGFAILURE INDICATIONS
ABS failure
ABS failure is indicated by the turning on
of warning light
>on the instrument pan-
el together with the dedicated message on
the multifunction display (where provid-
ed), (see section “Warning lights and mes-
sages”).
In this case the braking system is still effi-
cient, though without the aid of the ABS
system. Drive carefully to the closest Fiat
Dealership to have the system checked.

BRAKE ASSIST
(emergency braking assistance
integral with ESP) (where provided)
The system, which cannot be cut out, rec-
ognizes emergency braking (on the ground
of the brake pedal operation speed) and
considerably increases the pressure in the
brake circuit.
Brake Assist is deactivated on the versions
equipped with ESP, in the event of ESP sys-
tem failure (indicated by warning light
áswitching on together with the message
on the multifunction display, where pro-
vided).
ESP SYSTEM
(Electronic Stability
Program)
(where provided)
The ESP system is an electronic system
controlling the vehicle stability in the event
of tyre grip loss.
The ESP system is therefore particularly
useful when grip conditions of the road sur-
faces changes.
In addition to the ESP system, ASR system
and Hill Holder, (where provided) also the
MSR system (adjusting the engine braking
torque) and the HBA system (improving
the braking force during emergency brak-
ing) are provided.
ESP SYSTEM INTERVENTION
It is signalled by the blinking of the warn-
ing light áon the instrument panel, to in-
form the driver that the vehicle is in crit-
ical stability and grip conditions.
When the ABS cuts in, and
you feel the brake pedal pul-
sating, do not remove your foot, but
keep it pressed; in doing so you will
stop in the shortest amount of space
possible under the current road con-
ditions.
WARNING
EBD failure
EBD failure is indicated by the turning on
of warning lights
>and xon the in-
strument panel together with the dedi-
cated message on the multifunction dis-
play (where provided), (see section
“Warning lights and messages”).
In this case with sharp braking the rear
wheels might lock too early, with the pos-
sibility of skidding. Drive extremely care-
fully to the nearest Fiat Dealership to have
the system checked.
If warning light xalone
comes on (together with the
message on the multifunction display,
where provided), stop the vehicle im-
mediately and contact the nearest Fi-
at Dealership. Fluid leaks from the hy-
draulic system, in fact, can compro-
mise the braking system, both tradi-
tional systems and systems with ABS.

ESP SYSTEM ACTIVATION
The ESP system is automatically activat-
ed when the vehicle is started and cannot
be de-activated.
FAILURE INDICATIONS
In the event of failure, the ESP system is
automatically disconnected, the warning
light
á, comes on with fixed light on the
instrument panel, together with the mes-
sage on the multifunction display (where
provided) (see section “Warning lights and
messages”) and with the button led ASR.
In this case contact a Fiat Dealership as
soon as possible.
Performance of the ESP 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 and traffic.
Road safety is always the driver’s re-
sponsibility.
WARNING
HILL HOLDER SYSTEM
This system is an integral part of the ESP
system and it is provided to facilitate start-
ing on slopes.
It will activate automatically with the fol-
lowing conditions:
❒uphill: vehicle at a standstill on a road
with a gradient higher than 5%, engine
running, clutch and brake pedal
pressed, gearbox to neutral or en-
gaged gear other than reverse.
❒downhill: vehicle at a standstill on a
road with a gradient higher than 5%,
engine running, clutch and brake ped-
al pressed and reverse gear engaged.
At pickup the ESP system control unit will
keep brake force on wheels until reaching
the torque suitable for starting, or in any
case for max. 2 seconds in order to pass
easily from the brake pedal to the accel-
erator pedal.
After two seconds without starting, the
system will deactivate automatically by re-
leasing gradually the brake force.
At releasing, the typical brake disengage-
ment noise indicating that the vehicle is
going to move will be heard.Failure indications
System failure is indicated by the turning
on of warning light
á(see section “Warn-
ing lights and messages”).
IMPORTANT The Hill Holder system is
not a parking brake therefore, never leave
the vehicle without having engaged the
handbrake, turned the engine off and en-
gaged the first speed.
For correct operation of the
ESP and ASR systems, the
tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.

MSR system
(engine braking torque control)
It is an integral part of the ASR system that
in case of sudden gear shifting, cuts in pro-
viding torque to the engine thus prevent-
ing excessive driving wheel drive that, spe-
cially in poor grip conditions, can lead to
loss of stability.
Switching the systemon/off fig. 106
The ASR system switches on automatically
each time the engine is started.
When travelling, the ASR can be switched
off and on again by pressing switch Alo-
cated on the dashboard fig. 106. When the ASR is switched off this is
shown by the lighting up of the led on the
switch and by relevant message on the
multifunction display, where provided.
Versions equipped with ASR system on-
ly, at deactivation (ASR OFF) the warn-
ing light Vwill always stay on.
If the ASR is switched off when travelling,
it will turn on again automatically the next
time the engine is started.
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.
For correct operation of the
ESP and ASR systems, the
tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.
WARNING
fig. 106F0M0077m
ASR SYSTEM (Antislip Regulator)
The ASR function controls vehicle drive
and cuts in automatically every time one
or both driving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒if slipping involves both driving wheels,
the ASR function intervenes reducing
the power transmitted by the engine;
❒if the slipping involves only one dri-
ving wheel, the ASR system cuts in au-
tomatically braking the wheel that is
slipping.
The action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒too much power transmitted to the
wheels also in relation to the condi-
tions of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet sur-
face (aquaplaning).

In this case contact a Fiat Dealership as
soon as possible.
EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the vehicle correlat-
ed with emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument panel
(together with relevant message on the
multifunction display, where provided)
(see section “Warning lights and mes-
sages”), 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.IMPORTANT After eliminating the in-
convenience, to check the system com-
pletely, Fiat Dealerships are obliged to run
a bench test and, if necessary, road tests
which may also call for a long journey.
If turning the ignition key to
MAR, the warning light
Udoes
not turn on or if, while travel-
ling it turns on glowing steadily
or flashing (together with the message on
the multifunction display, where provid-
ed), contact Fiat Dealership as soon as
possible. Warning light
Uoperation can
be checked by means of special equipment
by traffic agents. Always comply with the
traffic regulations in force in the country
where you are travelling.

PARKING SENSORS
(where provided)
Parking sensors are located in the rear
bumper fig. 107and their function is to
inform the driver, through an intermittent
buzzer, about the presence of obstacles
behind the vehicle.
ACTIVATION
The sensors are automatically activated
when the reverse gear is engaged.
As the distance from the obstacle behind
the vehicle decreases, the acoustic alarm
becomes more frequent. BUZZER WARNINGS
When the reverse gear is engaged an in-
termittent acoustic signal is automatically
activated.
The acoustic signal:
❒becomes louder as the reduction of
distance between the vehicle and the
obstacle decreases;
❒becomes continuous when the dis-
tance between the vehicle and the ob-
stacle is less than 30 cm and stops im-
mediately if the distance raises;
❒is constant if the distance is unvaried;
if this situation concerns the side sen-
sors, the buzzer will stop after about
3 seconds to avoid, for example,
warning indications in the event of
manoeuvres along walls.Detection distances
Central action radius 140 cm ±10 cm
Side action radius 60 cm ±20 cm
If several obstacles are detected, the con-
trol unit indicates the nearest one.
FAILURE INDICATIONS
Parking sensor failures, if any, will be in-
dicated when engaging reverse by the
turning on of the instrument panel warn-
ing light
ttogether with the message on
the multifunction display, where provided
(see section “Warning lights and mes-
sages”).

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 vehicle
detergent, 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.
WARNINGOPERATION WITH
TRAILER
Parking sensor operation is deactivated au-
tomatically when the trailer electric cable
plug is fitted into the vehicle tow hook
socket.
Sensors are reactivated when removing
the trailer cable plug.
In washing stations, clean sensors quickly
keeping the vapour jet/high pressure
washing nozzles at 10 cm at least from the
sensors.

GENERAL WARNINGS
❒When parking, take the utmost care
to obstacles that may be set above or
under the sensors.
❒Objects set close to the vehicle, un-
der certain circumstances are not de-
tected and could therefore cause
damages to the vehicle or be dam-
aged.
Below are listed some conditions that
could affect the parking system perfor-
mance:
❒Reduced sensor sensitivity or re-
duced parking system performance
could be due to the presence on the
sensor surface of: ice, snow, mud,
multiple painting.
❒The sensor detects a non-existent ob-
ject (“echo disturbances”) caused by
disturbances of mechanical nature,
e.g.: vehicle washing, rain (extreme
wind conditions), hail.
❒Indications sent by the sensors can al-
so be altered by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the vehi-
cle.
❒Parking system performance could al-
so be affected by sensor position. For
instance, when trimming is changed
(due to wear of shock absorbers, sus-
pensions) or when changing tyres,
loading excessively the vehicle, car-
rying out specific tuning for lowering
the vehicle.
❒Obstacle detection at the top of the
vehicle (specially for vans or chassis
cabs) could not be guaranteed since
the system detects obstacles that can
strike the bottom of the vehicle.
