Fig. 174 In the front bumper: radar sensor
A radar sensor is fitted to the front bumper to monitor the traffic situation . Vehicles travelling ahead can thus be detected up to a distance of approximately 120 m.
The efficacy of the radar sensor can be impaired by contamination such as slush or snow, or by environmental conditions such as heavy rain or spray. In this case the area monitoring system (Front Assist) will not work. The instrument cluster display shows the message Front Assist: no sensor view!. Clean the radar sensors as required .
Front Assist will automatically be available again as soon as the radar sensor is no longer impaired. The message in the instrument cluster display goes out.
Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, or when near metallic objects such as rails in the road or metal plates used in roadworks, can impair the function of Front Assist.
The area in front of and around the radar sensor must not be covered by objects such as stickers or auxiliary headlights, as this can impair the function of Front Assist.
Any structural modifications to the vehicle, e.g. lowering the vehicle or making alterations to the front end trim, can impair the function of Front Assist. Structural modifications should therefore only be carried out by a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
Incorrectly performed repairs to the front end of the vehicle can alter the position of the radar sensor and therefore impair the function of Front Assist. Repair work should therefore only be carried out by a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
NOTICE
Receiver
The receiver collects the liquid droplets and directs them
in a continuous stream to the expansion valve. Moisture which
has entered the refrigerant circuit during assembly is collected
by the dessicant bag in the receiver.
