Drill the holes for the four ultrasound sensors with the enclosed 21 mm drill.
After drilling, smooth the holes with a file or a sharp blade.
Inserting the ultrasound sensors
The ultrasound sensors must always be
mounted horizontally, otherwise measur-
ing will be faulty. With slanted installation
sites, you can use the enclosed distancer
rings (7) for compensation.
Press the sensors in the right direction into
the openings until these lie flush on the
bumper.
Make sure to connect the ultrasound sensors in the right sequence. Start with sensor A on
the rear left (also see illustration „individual parts"). If the sequence is mixed up, the direc-
tion assignment of the LED display (3) is not correct.
Installing lines and components
Guide the connection cables of the ultrasound sensors from the outside through
the bumper to the trunk opening. Carefully place the cables inside so that no
moisture penetrates the inside of the car.
Attach the control unit with the enclosed adhesive pad. A suitable place is the
side wall in the watertight trunk close to a taillight. Make sure that the connec-
tion lines of the sensors reach up to the sensor units.
Install the connection cables of the sensors in line with the connection diagram
in „Individual parts".
When installing the cables in the sides of the car etc., make sure that you do not damage
any safety-relevant equipment (e.g. side airbags)
