In vehicles with a dual clutch gearbox DSG®, the adaptive cruise control (ACC) can brake the vehi-cle until it comes to a complete standstill behind a vehicle in front that is stopping.
Driver prompt to take over control
There are system-specific limits on the adaptive cruise control (ACC) when driving. This means that the driver may have to control the speed and dis-tance between the vehicle and other vehicles in certain circumstances.
The driver is told to take control of the vehicle via a message on the instrument cluster display prompts a braking intervention, and a signal tone =<>page 300.

• Cruise control system (CCS) =<>page 295
• Area monitoring system (Front Assist) =<>page 307
• Accessories, modifications, repairs and renewal of parts =<>page 394
A WARNING
The intelligent technology used in the adap-tive cruise control (ACC) cannot overcome the laws of physics, and functions only within the limits of the system. Careless or uninten-tional use of the adaptive cruise control (ACC) can cause accidents and lead to seri-ous injury. The system Is not a substitute for the full concentration of the driver.
• Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.
• Do not use the adaptive cruise control (ACC) in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. on snow, ice, wet roads, loose chippings or floo-ded roads.
A WARNING (Continued)
• Never use the adaptive cruise control (ACC) off-road or on unsurfaced roads. The adaptive cruise control (ACC) is designed for use on surfaced roads only.
• The adaptive cruise control (ACC) does not react to stationary obstacles, e.g. the tail end of a traffic jam, a vehicle that has broken down, or vehicles waiting at traffic lights.
• The adaptive cruise control (ACC) does not react to persons, animals or vehicles crossing or approaching in the same lane.
• If the adaptive cruise control (ACC) speed reduction is insufficient, you should brake the vehicle by depressing the foot brake.
• Brake the vehicle by depressing the brake if the vehicle rolls inadvertently on after the driver has been prompted to take control of the vehicle.
• If the instrument cluster display indicates that the driver should take control of the vehi-cle, you have to regulate the distance your-self.
• The driver must be prepared to take con-trol of the vehicle (by accelerating or braking) at all times.
CD
Switch off the adaptive cruise control (ACC) if you suspect that the radar sensor has been damaged. This can help to prevent secondary damage. Have the radar sensor realigned.
• Repair work on the radar sensor will require special knowledge and tools. Volkswagen rec-ommends using a Volkswagen dealership for this purpose.
m If the adaptive cruise control (ACC) does not L!J function as described in this chapter, do not use it, and have the system checked by a qualified workshop. Volkswagen recommends using a Voikswagen dealership for this purpose.
m The maximum vehicle speed when the adap-L!J live cruise control (ACC) is active is limited to either 160 km/h (1 00 m ph) or 210 km/h (130 m ph). depending on the system version.
m If the adaptive cruise control (ACC) is active, L!J unfamiliar noises may be heard during the automatic braking procedure. These are caused by the braking system. Driver assist systems I 299

A radar sensor is fitted to the front bumper to moni-tor the traffic situation 240 @.Vehicles trav-elling 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 en-vironmental conditions such as heavy rain or spray. This means that the adaptive cruise control (ACC) also will not work. The instrument cluster display shows the message ACC: No distance con-trol ! . Clean the radar sensors as required
The adaptive cruise control (ACC) will automatical-ly be available again as soon as the radar sensors are no longer impaired. The message on the in-strument cluster display goes out. and the adaptive cruise control (ACC) can be reactivated.
A WARNING (Continued)
• Never ignore any illuminated warning lamps or text messages.
CD
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle be-Ing damaged.
m When the adaptive cruise control (ACC) is L!..J switched on, some system-related displays on the instrument cluster can be overwritlen by other functions, e.g. incoming telephone calls. Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the adaptive cruise control (ACC).
The area in front of and around the radar sensor ® must not be covered by objects such as stick-ers, auxiliary headlights, face plates for number plates or the like, as this can impair the function of the adaptive cruise control (ACC).
Any structural modifications to the vehicle, e.g. lowering the vehicle or making alterations to the front end trim, can impair the function of the adap-tive cruise control (ACC). Structural modifications should therefore always be carried out by a quali-fied 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 the adaptive cruise control (ACC). Repair work should therefore only be carried out by a qualified workshop. Volks-wagen recommends using a Volkswagen dealer-ship for this purpose.
CD
Switch off the adaptive cruise control (ACC) If you suspect that the radar sensor has been damaged or is incorrectly positioned. This can help to prevent secondary damage. Have the radar sensor realigned.
