GENERAL WARNINGS
During parking manoeuvres, pay the utmost attention to any ob-
stacles that could be located above or below the sensors.
Sometimes, objects located close to the rear part of the car may
not be detected by the system and may damage the car or become
damaged themselves.
Here below are some conditions that may influence the perfor-
mance of the parking system:
❍ Reduced sensor sensitivity and a reduction in the parking as-
sistance 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 by the sensors can also be altered by the pres-
ence of ultrasound devices (e.g. pneumatic brake systems or
pneumatic drills) near the car;
❍ 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 vehicle may
not be guaranteed because the system detects obstacles that
could cause an impact with the vehicle in the bottom part.
