STARTING AND DRIVING

IMPORTANT NOTES
81)
8)
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
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.
The following conditions may influence
the performance of the parking sensors:
❒ the presence of ice, snow, mud or
think paint on the sensor surface may
cause reduced sensitivity of the sensor
itself and therefore reduce the system
performance;
❒ the sensor may detect a non-existent
obstacle (“echo interference”) due to
mechanical interference, for example
when washing the vehicle, in rain (strong
wind), hail;
❒ the signals sent by the sensor can also
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems
of trucks or pneumatic drills) near the
vehicle;
❒ 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.
81)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
used to assist the driver, who must never
allow his attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
IMPORTANT
8)The sensor must be clean of 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
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. Also, do not apply
stickers to the sensors.
