58)The system is an aid for the driver, who
must always pay full attention while driving.
The responsibility always rests with the
driver, who must take into account the
traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
59)If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).
60)The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
61)If the vehicle must be placed on a roller
bench for maintenance interventions or if
it is washed in an automatic roller washing
tunnel with an obstacle in the front part
(e.g. another vehicle, a wall or another
obstacle), the system may detect its
presence and activate. In this case the
system must be deactivated through the
settings of theUconnect™system.
62)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
63)iTPMS does not relieve the driver from
the obligation to check the tyre pressure
every month; it is not to be considered
a system to replace maintenance or a
safety system.64)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even if
it is higher than the prescribed value,
rather repeat the check when tyres are
cold.
65)The iTPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In
this case, stop the vehicle, braking with
caution and avoiding abrupt steering.
66)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
67)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
WARNING
22)The system may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow.
23)The section of the bumper before
the sensor must not be covered with
adhesives, auxiliary headlights or any other
object.
24)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
25)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front
geometry, tyre change, or a heavier load
than the standard load of the vehicle.26)Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may
alter the position of the radar sensor,
and adversely affect its operation. Go to a
Fiat Dealership for any operation of this
type.
27)Do not tamper with nor carry out any
intervention on the radar sensor or on
the camera on the windscreen. In the event
of a sensor failure, contact a Fiat
Dealership.
28)When towing a trailer (with modules
installed after purchasing the vehicle),
a vehicle or during loading manoeuvres on
a vehicle transporter (or in vehicle for
transport), the system must be deactivated
via theUconnect™system.
29)Do not wash with high-pressure jets in
the bumper lower area: in particular do
not operate on the system's electrical
connector.
30)Be careful in the case of repairs and
new paintings in the area around the
sensor (panel covering the sensor on the
left side of the bumper). In the event of
a frontal impact the sensor may
automatically deactivate and display a
warning to indicate that the sensor needs
to be repaired. Even without a malfunction
warning, deactivate the system operation
if you think that the position of the radar
sensor has changed (e.g. due to
low-speed frontal impact as during parking
manoeuvres). In these cases, go to a Fiat
Dealership to have the radar sensor
realigned or replaced.

Detection distancesIf several obstacles are detected by the
sensors, only the nearest one is
considered.Indication on displayThe indications regarding the Park
Assist system are shown on the
instrument panel display only if the
"Acoustic signal and display" item in the
"Settings" menu of theUconnect™
system is selected (for more
information, see the description in the
dedicated chapter).
The system indicates the presence of
an obstacle by displaying a single arc in
one of the possible areas, in
accordance with the distance of the
object and the position in relation to the
vehicle. If the obstacle is detected in
the rear central area, a single arc will be
displayed as the obstacle approaches,
first constant, then flashing, in addition
to an acoustic signal.OPERATION WITH
TRAILERThe operation of the sensors is
automatically deactivated when the
trailer's electrical connection is inserted
in the vehicle's tow hook socket.Sensors are reactivated on removing
the trailer's electrical connection.
Before using the Park Assist system, it
is recommended to remove the tow
hook ball assembly and the relevant
attachment from the vehicle Failure to
comply with this prescription may
cause personal injuries or damage to
vehicles or obstacles since, when
the continuous acoustic signal is
emitted, the tow hook ball is already in
a position that is much closer to the
obstacle than the rear bumper. In
addition, the sensors may provide a
false indication, interpreting the tow
hook ball assembly and the relevant
attachment as an obstacle in the area
behind the vehicle.
GENERAL WARNINGSSome conditions may influence the
performance of the parking system:
❒reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to
the presence of: ice, snow, mud, paint,
etc. on the surface of the sensor;
❒the sensor may detect a non-existent
obstacle ("echo interference") due to
mechanical interference, for example
when washing the vehicle, in rain
(strong wind), hail;❒the signals sent by the sensor can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic
drills) near the vehicle;
❒Parking assistance system
performance can also be influenced by
the position of the sensors, for example
due to a change in the ride setting
(caused by wear to the shock
absorbers, suspension), or by changing
tyres, overloading the vehicle or fitting
specific trims that require the vehicle to
be lowered;
❒the presence of a tow hook without
trailer, which may interfere with the
correct operation of the parking
sensors. If a fixed tow hook is installed,
the parking sensors cannot operate
correctly. In the case of vehicles fitted
with removable tow hook, whether
as standard or installed after the vehicle
was purchased, it is advisable to
remove it whenever it is not used, to
prevent incorrect operation of the
sensors;
❒the presence of adhesives on the
sensors. Therefore, take care not to
place adhesives on the sensors.

TOWING TRAILERSIMPORTANT
120) 121)
For towing caravans or trailers the
vehicle must be fitted with an approved
tow hook and an adequate electrical
system. Should aftermarket installation
be requested, this must be carried
out by specialists.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that when towing a trailer,
steep hills are harder to climb, braking
distances increase and overtaking
takes longer depending on the overall
weight of the trailer. Engage a low gear
when driving downhill, rather than
constantly using the brake. The weight
the trailer exerts on the vehicle tow
hook reduces the vehicle's loading
capacity by the same amount. To make
sure that the maximum towable weight
is not exceeded (given in the vehicle
registration document) account should
be taken of the fully laden trailer,
including accessories and luggage.
Do not exceed the speed limits specific
to each country you are driving in, in
the case of vehicles towing trailers.
In any case, the top speed must not
exceed 100 km/h.Any electric brake must be powered
directly by the battery through a cable
with a cross-section of no less than 2.5
mm
2. In addition to the electrical
branches, the vehicle electrical system
can only be connected to the supply
cable for an electric brake and to the
cable for an internal light for the trailer,
not exceeding 15 W. For connections,
use the preset control unit with a
battery cable with section not less than
2.5 mm
2. The use of auxiliary loads
other than external lights (e.g. electric
brake) must take place with engine
running.
INSTALLING A TOW
HOOKThe towing device should be fastened
to the body by specialised personnel
according to any additional and/or
integrative information supplied by the
Manufacturer of the device. It must also
meet current regulations with reference
to Directive 94/20/EC and subsequent
amendments.
For any version the towing device used
must be right for the towable weight
of the vehicle on which it is to be
installed.For the electrical connection a standard
connector should be used which is
generally placed on a special bracket
normally fastened to the towing device,
and a special ECU for external trailer
light control must be installed on the
vehicle. 7 or 13-pin 12 V DC
connections should be used (CUNA/
UNI and ISO/DIN Standards). Follow
any instructions provided by the vehicle
manufacturer and/or the towing device
manufacturer.
