The warning lamp and a message are displayed on the instrument cluster display in the event
of malfunctions.
If the malfunction cannot be rectified by one of the listed measures, switch off ACC and go to a
qualified workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.

Troubleshooting
The area monitoring system (Front
Assist) with City Emergency Braking
System can help to avoid accidents.
Within the limits of the system, Front Assist can warn the driver about imminent collisions, prepare
the vehicle for emergency braking, assist with braking, and initiate automatic braking. The warning
time varies depending on the traffic situation and driver behaviour.
Front Assist is not a substitute for the full concentration of the driver.
Driving with Front Assist
You can cancel the automatic braking interventions of Front Assist by steering or pressing the
accelerator.
Automatic braking
Front Assist can decelerate the vehicle to a standstill. The vehicle will then not be held
permanently. Depress the brake pedal.
The brake pedal will feel harder during an automatic braking operation.
Radar sensor
Front Assist detects driving situations by means of the radar sensor at the front of the vehicle

Front view
. The range of the radar sensor is up to approximately 120 m.
