Distance Control (Adk) - Volkswagen PASSAT - YEAR 2001 Manual

Distance control (ADK)

The distance control (ADK) aids parking in
reverse. For this purpose, four ultrasound
converters are built into in the rear bumper. The
control unit is located in the luggage
compartment on the rear left. The tone generator
is under the rear window shelf in the saloon and
built into the control unit in the Variant.
The distance warning system begins to emit
acoustic signals when the vehicle reverses to
within a distance of 1.60 m of an obstacle. The
frequency of the audio signal varies with
decreasing distance to the obstacle. The
intermittent audio signal becomes a continuous
tone when the vehicle reverses to within 20 cm of
the obstacle.
The system is active as soon as the ignition is
turned on and reverse gear is selected.
