brake sensor Alfa Romeo 4C Spider 2016 Owner's Manual

•Mechanical interference (e.g washing the vehicle, rain,
strong wind, hail) may cause the sensor to detect a
non-existent obstacle (“echo interference”).
• The presence of ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic drills) near the
vehicle could alter the signals sent by the sensor.
• The variation in sensor position, caused by variation in
ride (due to suspension component wear), changing
tires, overloaded vehicle, or tuning that lowers the
vehicle, for example, may affect parking sensor system
performance. NOTE:The sensor must be free from 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 car sham-
poo 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 4 in (10 cm)
away. Also, do not apply stickers to the sensors.
CAUTION!
• The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be tem-
porarily detected or not detected at all. Obstacles
located above or below the sensors will not be
detected when they are in close proximity
