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 sensor may detect a non-
existent obstacle (echo noise) due to
mechanical noises, for example
when washing the vehicle, in case of
rain, strong wind, hail.
❒The signals sent out by the sensors
can be altered by dirt, snow or ice
deposited on the sensors or by
ultrasound systems (e.g. truck
pneumatic brakes or pneumatic drills)
near the vehicle.
❒The performance of the parking
assistance system may also be
affected by the position of the
sensors. For example by a change in
the ride setting (caused by the wear
of the shock absorbers, suspension),
changing the tyres, overloading the
vehicle and carrying out specific
tuning operations that require the
vehicle to be lowered.❒Detection of obstacles in the upper
part of the vehicle (particularly in the
case of vans or chassis cabs) may
not be guaranteed because the
system detects obstacles that could
strike the lower part of the vehicle.
❒The parking sensors work properly
with the swing doors closed.
❒If they are open, they can cause the
system to send false signals: always
close the rear doors.
❒Do not apply stickers to the sensors.
WARNING
97) The sensors must be clean of
mud, dirt, snow and 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 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.98) Parking manoeuvres, however,
are 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
sensor is designed to assist
drivers, who must still never allow
their attention to lapse during
potentially dangerous
manoeuvres even if performed at
low speed.
