OPERATION WITH TRAILER
Parking sensor operation is deactivated
automatically when the trailer electric ca-
ble plug is fitted into the car tow hook
socket.
Sensors are reactivated when removing
the trailer cable plug.
The sensor must be clean
from mud, dirt, snow or ice in
order for the system to work.
Be careful not to scratch or
damage the sensor while cleaning
them. Avoid using dry, rough or hard
cloths. Clean the sensors with clean
water with the addition of car sham-
poo if necessary. In washing stations,
clean sensors quickly keeping the
vapour jet/high pressure washing noz-
zles at 10 cm at least from the sensors.

GENERAL WARNINGS
❒ When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors.
❒ Objects located close to the car, under
certain circumstances are not detected
and could therefore cause damages to
the car or be damaged.
Here are some situations which may in-
fluence parking system performance:
❒ A reduced sensibility of the sensor and
parking system performance degrada-
tion may be due to the presence on the
sensor surface of: ice, snow, mud, mul-
tiple varnishing
❒ The sensor detects a non-existing ob-
ject ("echo disturbance") due to me-
chanic disturbances, e.g.: car wash, rain
(strong winds), hail.
❒ The signals sent by the sensor can be
altered by ultrasound systems (e.g.:
truck pneumatic brakes or pneumatic
hammers) set nearby the car.
❒ The performance of the parking assist
system can be influenced by the posi-
tion of the sensors, e.g. changing the
suspension levels (due to shock ab-
sorbers wear, suspensions wear) or re-
placing the tyres, overloading the car,
adjusting suspension level to lower the
car.
WARNING
The driver is always and on-
ly responsible for parking
and other dangerous manoeuvres.
Make sure that no-one is standing in
the area, especially children or ani-
mals. Parking sensors are designed to
assist drivers: in all cases, you must al-
ways pay the utmost attention during
potentially dangerous manoeuvres.
