ECU Alfa Romeo Giulietta 2018 User Guide

When reverse gear is engaged an
acoustic signal is automatically activated
if there is an obstacle within the range of
operation.
The acoustic signal:
increasesas distance between the car
and the obstacle decreases;
becomes continuouswhen the
distance between the car and the
obstacle is less that 30 cm and stops
immediately if the distance increases;
is constantif the distance is unvaried;
if this situation occurs for the side
sensors, the signal will stop after about
3 seconds to avoid, for example,
indications in the event of manoeuvres
alongside walls.
OPERATION WITH A TRAILER
Parking sensor operation is automatically
turned off when the trailer electric cable
plug is fitted into the car tow hook
socket.
31)
The sensors are automatically
reactivated when the trailer's cable plug
is removed.
101) 102)
IMPORTANT NOTES
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Objects set close to the car rear, under
certain circumstances are not detectedand could therefore cause damage to the
car or be damaged.
The following conditions may influence
the performance of the parking
assistance system:
reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to the
presence on the surface of the sensor of:
ice, snow, mud, thick paint
The sensors may detect a
non-existent obstacle (echo interference)
due to mechanical interference, for
example when washing the car, in rain
(strong wind), hail.
The signals sent by the sensors can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic brake
systems or pneumatic drills) near the
vehicle.
sensor performance can also be
influenced by the position of the sensors.
For example by a change in the ride
setting (caused by the wear of the shock
absorbers, suspension), overloading the
car and carrying out specific tuning
operations that require the car to be
lowered;
The detection of obstacles at the top
part of the car may not be guaranteed
because the system detects obstacles
that could cause an impact with the car in
the bottom part.
IMPORTANT
31)The sensor must be free of mud, dirt,
snow or ice in order for the system to work.
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 vehicle 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.
WARNING
101)Only have the bumpers repainted or
any retouches to the paintwork in the area of
the sensors carried out by an Alfa Romeo
Dealership. Incorrect paint application could
affect the operation of the parking sensors.
102)Parking and other dangerous
manoeuvres are, however, always the
driver’s responsibility. 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 the driver must
never allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
