152 STARTING AND OPERATING
WARNING!
Ultrasonic sources, such as the compressed-air
brakes of heavy trucks, a car wash or a pneumatic
drill, and other parts attached to the vehicle, such
as load carriers, could cause the reversing aid to
malfunction.
The reversing aid sensors must not be scratched
or damaged. They must be free from dirt, ice and
slush, otherwise they might not function
correctly.
The rear area sensors will be restricted in all of
these cases. This will increase the risk of damage
to the vehicle or the object and the risk of injury
to other persons.
Clean the sensors regularly, taking care not to
scratch or damage them.
Range of Sensors
The sensors are able to detect a distance within a range
of up to 70 in (180 cm) centrally or up to 40 in (100 cm)
laterally behind the bumper.
