2015 Alfa Romeo 4C parking sensors

GETTING TO KNOW YOUR CAR
In-depth knowledge of your new car
starts here.
The booklet that you are reading simply
and directly explains how it is made
and how it works.
That’s why we advise you to read it
seated comfortably on board, so that
you can see what is described here for
yourself.SYMBOLS ...................................... 10

Fiat Group Automobiles S.p.A.
authorises the installation of transceiver
devices on condition that such
installations are carried out in
a workmanlike fashion, following the
manufacturer’s instructions, at a
specialised centre.
IMPORTANT Traffic police may not
allow the car on the road if devices
have been installed which modify the
features of the car. This may also cause
invalidation of warranty in relation to
faults caused by the change either
directly or indirectly related to it.
Fiat Group Automobiles S.p.A. shall not
be liable for damage caused by the
installation of accessories either not
supplied or recommended by Fiat
Group Automobiles S.p.A. and/or not
installed in compliance with the
provided instructions.
RADIO TRANSMITTERS
AND MOBILE PHONES
Radio transmitter equipment (vehicle
mobile phones, CB radios, amateur
radio etc.) cannot be used inside the
car unless a separate aerial is mounted
on the roof.IMPORTANT The use of these devices
inside the passenger compartment
(without a separate aerial) may cause
the vehicle’s electronic systems to
malfunction. This could compromise
safety in addition to constituting a
potential hazard for passengers' health.
As far as the use of EC-approved
mobile phones is concerned (GSM,
GPRS, UMTS), follow the usage
instructions provided by the mobile
phone manufacturer.
WARNING
44) Take care when fitting additional
spoilers or non-standard alloy
wheels: they could reduce the
ventilation of the brakes and
affect efficiency in sharp,
repeated braking or on long
descents. Make sure that nothing
obstructs the pedal stroke (mats,
etc.).
PARKING SENSORS
(for versions/markets, where provided)
They are located in the rear bumper
fig. 53 and their function is to detect the
presence of any obstacles near the
rear part of the car; they consequently
inform the driver, through an
intermittent acoustic signal.
ACTIVATION/
DEACTIVATION
The sensors are automatically activated
when reverse gear is engaged. As the
obstacle behind the car gets closer, the
acoustic signal becomes more
frequent.
53A0L0043
51

ACOUSTIC SIGNAL
When reverse gear is engaged and
there is an obstacle behind the vehicle,
an acoustic signal is emitted which
varies according to the distance of the
bumper from the obstacle.
The frequency of the acoustic signal:
❒increases as the distance between
car and obstacle decreases,
culminating in a continuous acoustic
signal, when the distance is less
than approximately 30 cm;
❒decreases if the distance from the
obstacle increases, until the signal
ceases entirely;
❒remains constant if the distance
between car and obstacle remains
unchanged; if this situation concerns
the side sensors, the signal will
stop after approximately 3 seconds
to avoid, for example, indications
in the event of manoeuvres along a
wall.
If several obstacles are detected by the
sensors, only the nearest one is
considered.INDICATIONS ON
DISPLAY
(for versions/markets, where provided)
When the sensors are activated, the
screen in fig. 54 appears on the display.
Obstacle presence and distance
information is therefore provided both
by the acoustic signal and the
instrument panel display.
The system indicates a detected
obstacle by displaying an arc in one or
more positions according to the
distance of the obstacle and its position
in relation to the car.
If an obstacle is detected in the rear
central area, the display shows all the
arcs in the rear central area, up to
the one that corresponds to the
position of the obstacle itself.The signal is similar for obstacles in the
rear left or right area.
The arc that corresponds to the
position of the obstacle will flash.
The colour on the display depends on
the distance from and position of the
obstacle.
The car is close to the obstacle when
the display shows a single constant arc
and emits a continuous sound.
If there are several obstacles, the
closest one is indicated.
FAULT INDICATION
Parking sensor failures, if any, will be
indicated when reverse is engaged by
the switching on of the
warning
light on the instrument panel together
with the message on the display (see
“Warning lights and messages”
chapter).
GENERAL WARNINGS
45)
4)
When parking, take the utmost care
over obstacles that may be above
or under the sensor.

GETTING TO KNOW YOUR CAR

Under certain circumstances, objects
close to the vehicle are not detected by
the system and could therefore cause
damage to the car or be damaged
themselves.
Some conditions may influence the
performance of the parking sensors:
❒the presence of ice, snow, mud
or multiple layers of paint on the
sensor surface may cause reduced
sensitivity of the sensor itself and
therefore reduce the system
performance;
❒mechanical interference (e.g. washing
the car, rain, strong wind, hail) may
cause the sensor to detect a
non-existent obstacle ("echo
interference");
❒the presence of ultrasonic systems
(e.g. pneumatic brake systems of
trucks or pneumatic drills) near the
car could alter the signals sent by the
sensor;
❒the variation in sensor position,
caused by variation in ride (due
to suspension component wear),
changing tyres, overloaded car,
or tuning that lowers the car, for
example, may affect parking sensor
system performance.
WARNING
45) The responsibility for parking
and other dangerous manoeuvres
always and in every case lies
with the driver. While carrying out
these manoeuvres, always make
sure that no people (especially
children) or animals are in the
area concerned. The parking
sensors are an aid for the driver,
but must never allow their
attention to lapse during
potentially dangerous
manoeuvres, even those executed
at low speeds.
IMPORTANT
4) The sensor must be free from
mud, dirt, snow or ice in order for
the system to operate correctly.
Be careful not to scratch or
damage the sensors while
cleaning them. Avoid using dry,
rough or hard cloths. The sensors
must be washed using clean
water, with the addition of car
shampoo if necessary. When
using special washing equipment
such as high pressure jets or
steam cleaning, clean the sensors
very quickly keeping the jet more
than 10 cm away. Also, do not
apply stickers to the sensors.
