2018 FIAT 500C sensor

REAR PARK ASSIST
The Rear Park Assist system provides audible and visual
indications of the distance between the rear fascia/bumper
and a detected obstacle when backing up, e.g. during a
parking maneuver. Refer to the “Park Assist System Usage
Precautions” for the limitations of this system and recom-
mendations.
The Rear Park Assist is automatically activated when the
transmission is placed into REVERSE.
Rear Park Assist Sensors
The four Rear Park Assist sensors, located in the rear
fascia/bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles, in the horizontal direction, from approximately
12 inches (30 cm) up to 55 inches (140 cm) from the center
of the rear fascia/bumper and up to 24 inches (60 cm) from
the corners of the rear fascia/bumper, depending on the
location, type and orientation of the obstacle.
If several obstacles are detected, the Rear Park Assist
system indicates the nearest obstacle.
The minimum height of a detectable obstacle corresponds
to the maximum height of an obstacle that would clear the
underside of the vehicle during the parking maneuver. Rear Park Assist Warning Display
The Rear Park Assist Warning screen is located within the
instrument cluster display. It provides audible and visual
warnings to indicate the distance between the rear fascia/
bumper and the detected obstacle. The settings can be
adjusted through the Uconnect screen. Refer to  Uconnect
Settings  in “Multimedia  for further information.
Rear Park Assist Display
When the vehicle is in REVERSE, the warning display will
turn ON indicating the system status.
The system will indicate a detected obstacle by showing
arcs in one or more regions based on the obstacle’s distance
and location relative to the vehicle.
If an obstacle is detected in the center rear region, the
display will show solid arcs in the center rear region and
will produce an audible alert. As the vehicle moves closer
to the obstacle, the display will show fewer arcs and the
audible alert becomes more frequent.
If an obstacle is detected in the left and/or right rear
region, the display will show solid arcs in the left and/or
right rear region and will produce an audible alert. As the
vehicle moves closer to the obstacle, the display will show
fewer arcs and the audible alert becomes more frequent. 6STARTING AND OPERATING 181

Rear Park Assist Audible Alerts
If an obstacle is behind the vehicle when the transmission
is placed into REVERSE, an audible alert is activated.
The tones emitted by the loudspeaker inform the driver
that the vehicle is approaching an obstacle. The pauses between the tones are directly proportional to the distance
from the obstacle. Pulses emitted in quick succession indi-
cate the presence of a very close obstacle. A continuous tone
indicates that the obstacle is less than 12 inches (30 cm)
away.
Audible And Visual Signals Supplied By The Rear Park Assist System
SIGNAL MEANING INDICATION
Obstacle Distance An obstacle is present
within the sensors’ field of
view Audible Signal (dashboard loudspeaker)
• Sound pulses emitted at a rate that increases as the
distance decreases.
• Emits continuous tone at 12 inches (30 cm).
• Adjustable volume level. (Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.)
Visual Signal (Instrument Cluster Display)
• Arcs are shown based on the obstacle’s distance and
location relative to the vehicle. (Refer to “Rear Park
Assist Display” for further information).
Failure Sensor or System failures Visual Signal (Instrument Panel)
• Icon appears on display.
• Message appears on the instrument cluster display
(if equipped).182 STARTING AND OPERATING

While audible signals are emitted, the audio system is not
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition
occurs for the external sensors, the signal is turned off after
three seconds (stopping warnings during maneuvers par-
allel to walls).
Failure Indications
A malfunction of the Rear Park Assist sensors or system is
indicated, during REVERSE gear engagement, by the in-
strument panel warning icon and message appearing on
the instrument cluster display.
The warning icon is illuminated and a message
appears on the instrument cluster display. Re-
fer to  Instrument Cluster Display  in “Getting
To Know Your Instrument Panel” for further
information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indicated
immediately if they occur when the system is on.
Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display shall indicate that the Rear Park Assist system is unavailable,
without reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be disabled.
The system is turned off automatically.
Cleaning The Rear Park Assist System
Clean the Rear Park Assist sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. In
washing stations, clean sensors quickly keeping the vapor
jet/high pressure washing nozzles at least 4 inches (10 cm)
from the sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
Park Assist System Usage Precautions
NOTE:
• Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt or
other obstruction to keep the Rear Park Assist system
operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of Rear Park Assist.
• Clean the Rear Park Assist sensors regularly, taking care
not to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris. 6STARTING AND OPERATING 183

Failure to do so can result in the system not working
properly. The Rear Park Assist system might not detect
an obstacle behind the fascia/bumper, or it could pro-
vide a false indication that an obstacle is behind the
fascia/bumper.
• Objects such as bicycle carriers, etc., must not be placed
within 12 inches (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so can result in
the system misinterpreting a close object as a sensor
problem, causing a failure indication to be displayed in
the instrument cluster display.
WARNING!• Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind
your vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon-
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is (Continued) WARNING! (Continued)disconnected from the vehicle when the vehicle is
not used for towing. Failure to do so can result in
injury or damage to vehicles or obstacles because the
hitch ball will be much closer to the obstacle than the
rear fascia when the loudspeaker sounds the con-
tinuous tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on its size
and shape, giving a false indication that an obstacle
is behind the vehicle.
CAUTION!• ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.184 STARTING AND OPERATING
