When the highest level is reached, the distance re-turns to the lowest level when the button is press-ed again.
The distance level can also be set using the Q or Q buttons on the multifunction steering wheel im-mediately after the(!) button on the multifunction steering Fig. 241 has been pressed.
Select the Settings menu, Assist systems submenu, ACC to set the distance to be used when the ACC is switched on 24.
Setting the gearbox programme
The acceleration response can be influenced by the gearbox programme selected. The programme can be set Using the ACC option in the Assistant submenu in the Settings menu. The following gearbox programmes can be selected:
• Normal
• Sport
• Eco
The following conditions can prevent the adaptive cruise control (ACC) from reacting:
• If the accelerator is depressed.
• If no gear is selected.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the vehicle is reversing.
• System version 1: if the vehicle is travelling faster than approximately 160 km/h (1 00 m ph).
• System version 2: if the vehicle is travelling faster than approximately 210 km/h (130 mph).
A WARNING
If you do not maintain the minimum distance to a vehicle In front and the difference In speed between the two vehicles is so great that the braking action of the adaptive cruise control (ACC) is insufficient, you are In dan-ger of colliding with the vehicle in front. You should reduce the vehicle speed immediately with the foot brake.
• The adaptive cruise control (ACC) may not be able to detect all driving situations cor-rectly.
• Leaving your foot on the accelerator means that the adaptive cruise control (ACC) will not brake automatically. This is because manual acceleration overrides the system.
• You should always be prepared to brake the vehicle yourself.
• Observe country-specific regulations re-garding the minimum distance.
m The set speed will be deleted if the ignition or L!.J the adaptive cruise control (ACC) is switched off.
m The adaptive cruise control (ACC) is auto-L!.J matically deactivated when the traction con-trol system (TCS) is deactivated.
m In vehicles with a start/stop system, the en-L!.J gine is switched off automatically during the stationary phase of adaptive cruise control (ACC) and is then restarted for moving off. Switch off the adaptive cruise control (ACC) temporarily in the following
situations
1""111 First read and observe the introductory L-J,:.IJ Information and safety warnings & on page 298.
The adaptive cruise control (ACC) should be switched off in the following situations due to sys-tem limitations &:
304 I While driving
• When turning off roads, driving around round-abouts, narrow curves, joining motorways, exiting from motorways or driving through road works, to prevent the vehicle from unnecessarily accelerat-ing to the set speed in these situations
• When driving through a tunnel as this situation could impair the system function.
• On roads with more than one lane, if other vehi-cles are driving more slowly in the fast lane. The slower vehicles In the other lane would be overtak-en from the right side in this case.
• In heavy rain, snow or spray as vehicles travel-ling ahead cannot be monitored sufficiently or maybe cannot be monitored at all. .,.

A WARNING
Failure to switch off the adaptive cruise con-trol (ACC) in the above-mentioned situations can cause accidents and result in serious in-juries.

The adaptive cruise control (ACC) has physical and system-related limits. As a result, certain adaptive cruise control (ACC) system reactions may occur, from the driver's perspective, unexpect-edly or with some delay. You should therefore al-ways be prepared to take full control of the vehicle if necessary.
The following traffic situations, for example, require particular vigilance:
Deceleration to standstill, only vehicles with dual clutch gearbox DSG®
If a vehicle travelling ahead brakes to a standstill, the adaptive cruise control (ACC) will also brake your vehicle to a standstill. The vehicle is then held stationary by the brakes.
Stationary phase, only vehicles with dual clutch gearbox DSG®
After the adaptive cruise control (ACC) has slowed down the vehicle to standstill, the vehicle is kept stationary for a short period of time. During the sta-tionary phase the driver is prompted to depress the brake pedal 300. If the brake pedal is de-pressed, the adaptive cruise control (ACC) is switched off. If the brake pedal is not depressed within the stationary phase, the adaptive cruise control (ACC) is switched off automatically.
Overtaking
If the tu m signal is activated when starting an over-taking manoeuvre, the adaptive cruise control (ACC) accelerates the vehicle automatically and thus reduces the distance to the vehicle in front.
If you move your vehicle into the overtaking lane and there is no vehicle ahead of you, the adaptive cruise control (ACC) will automatically increase the speed to your set level and maintain it. .,..
Driver assist systems I 305

Acceleration can be stopped at any time by de-pressing the brake pedal or pressing the(@ or @ button on the multifunction steering wheel 302.
When driving through bends
While driving through bends, the radar sensor may sometimes lose the vehicle travelling ahead or may react to a vehicle in the next lane 242 !Al. In such situations, the vehicle might decelerate unnecessarily or not react to the vehicle in front. In this case the driver must override the adaptive cruise control (ACC) by depressing the accelerator, or interrupt the braking procedure by depressing the brake pedal or pressing or @ button on the multifunction steering wheel 302.
Driving in tunnels
The radar sensor function may be restricted in tun-nels. Switch off the adaptive cruise control (ACC) in tunnels.
Narrow vehicles and a zig-zag traffic situation
Narrow vehicles and vehicles travelling slightly to the left or right of your vehicle will only be recog-nised by the radar sensor once they have entered the radar range 242@ This applies in par-ticular to narrow vehicles such as motorbikes. If re-quired, brake the vehicle yourself.
Vehicles with special load or special equipment
Any load or accessories on other vehicles that pro-trude from the side, rear or over the roof of the ve-hicle may not be detected by the adaptive cruise control (ACC) .
Switch off the adaptive cruise control (ACC) when the vehicle ahead has special load or special equipment, or while overtaking vehicles of this kind. If required. brake the vehicle yourself.
When other vehicles change lanes
Vehicles that are very close when they move into your lane can only be detected by the radar sen-sors when they have moved into the sensor range. This means that the adaptive cruise control (ACC) may have a delayed reaction =>Fig. 243@]. If re-quired, brake the vehicle yourself.
Stationary vehicles
The adaptive cruise control (ACC) does not detect stationary objects during a journey, e.g. stationary traffic or a vehicle that has broken down.
306 I While driving
If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise con-trol (ACC) and this vehicle turns off the road or changes lane, the adaptive cruise control (ACC) will not be able to react to the stationary vehicle 243 [Q]. If required, brake the vehicle your-self.
Oncoming vehicles and vehicles crossing your path
The adaptive cruise control (ACC) does not react to approaching vehicles or vehicles crossing your path.
Metal objects
Metal objects, such as tracks in the road or metal plates used in roadworks, can confuse the radar sensor and cause incorrect reactions from the adaptive cruise control (ACC) .
Possible radar sensor function impairments
The adaptive cruise control (ACC) will switch off temporarily if the radar sensor function is impaired, e.g. due to heavy rain, spray, snow, ice or mud. A corresponding message will appear on the instru-ment cluster display. 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.
Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the radar sensor.
Towing a trailer
The adaptive cruise control (ACC) operates with reduced dynamics when the vehicle is towing a trailer.
Overheated brakes
If the brakes overheat, e.g. following heavy braking or when driving down steep inclines for long peri-ods, the adaptive cruise control (ACC) may be de-activated temporarily. A corresponding message will appear on the instrument cluster display. lt is then not possible to activate the adaptive cruise control (ACC).
As soon as the temperature of the brakes has de-creased sufficiently, the adaptive cruise control (ACC) can be activated again. The message on the instrument cluster display goes out. If the mes-sage ACC not ava i 1 able does not go out for a long time, there is a fault. Go to a qualified work-shop. Volkswagen recommends using a Volkswa-gen dealership for this purpose.

The area monitoring system (Front As-
sist) can help to avoid rear-end colli-
sions.
Within the limits of the system, Front Assist can warn the driver about imminent collisions, prepare the vehicle for emergency braking in case of dan-ger, assist with braking, and initiate automatic braking.
Front Assist is not a substitute for the full con-centration of the driver.

Distance warning
If the system detects danger from driving too close to the vehicle in front, within the speed range of approx. 60 km/h (37 mph) up to 210 km/h (130 mph), the system warns the driver by showing a corresponding message on the instrument clus-ter display 244 [ID.
The warning period varies according to the traffic situation and the driver's response.
Advance warning
If the system detects a danger of collision with the vehicle ahead, within the speed range of approx. 30 km/h (18 m ph) up to 210 km/h (130 mph), the system warns the driver by emitting a signal tone and showing a corresponding message on the in-strument cluster display 245.
The warning period varies according to the traffic situation and the driver's response. At the same time it prepares the vehicle for possible emergency
Urgent warning
If the driver fails to respond to the advance warn-ing, within a speed range of approx. 30 km/h (18 mph) to 210 km/h (130 mph), the system can initiate a quick jolt of the brake in order to draw the driver's attention to the increasing danger of a colli-sion. The warning period varies according to the traffic situation and the driver's response.
Automatic braking
If the driver does not react to the acute warning, within a speed range of approx. 4 km/h (2.5 mph) to 210 km/h (130 mph), the vehicle can brake auto-matically using brake pressure with gradually in-creasing intensity. By reducing speed during a pos-sible collision the system can help to minimise the consequences of an accident.
Brake assistance
If the system detects that the driver is not braking sufficiently when there is a risk of collision, the sys-tem can increase the braking force and thereby help to prevent a collision from speeds of approxi-mately 4 km/h (2.5 mph) to 210 km/h (130 mph). Brake assistance works only for as long as the brake pedal is pressed hard.
A WARNING
The Intelligent technology used in Front As-sist cannot overcome the laws of physics, and functions only within the limits of the system. The driver Is always responsible for braking in time. If Front Assist issues a warn-ing, immediately apply the foot brake to slow the vehicle down or avoid the obstacle, de-pending on the traffic situation.
• Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.
• Front Assist cannot prevent accidents and serious injuries on Its own.
• Front Assist can issue unnecessary warn-Ings and carry out unwanted braking inter-ventions in certain complex driving situa-tions, e.g. at traffic Islands.

City Emergency Brake function
Fig. 247 The display in the instrument cluster: ad-vance warning display.
,...-m First read and observe the introductory information and safety warnings & on page 307.
The City Emergency Brake function is part of the area monitoring system (Front Assist) and is active when Front Assist is switched on.
The front scan system and thus the City Emergen-cy Brake function can be activated and deactivated using the Assistant menu in the Volkswagen in-formation system or the Front Assist option in the Assistant submenu of the Settings menu 24.
The City Emergency Brake function gathers infor-mation on the traffic situation up to a distance of about 10 m in front of the vehicle within a speed range of about 5 km/h (3 m ph) to 30 kmlh (19 mph).
The system prepares the vehicle for emergency braking if it detects a possible collision with a vehi-cle ahead &.
If the driver does not react to a possible serious collision, the system can automatically stop the ve-hicle with brake pressure with increasing intensity so as to reduce the speed in a possible collision. Hence the system can help minimise the conse-quences of an accident.
Display
Automatic deceleration by the City Emergency Brake function will be shown by the advance warn-ing display in the instrument Fig. 247.
A wARNING
The intelligent technology used in the City Emergency Brake cannot overcome the laws of physics, and functions only within the lim-its of the system. The driver is always re-sponsible for braking In time.
• Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.
• The City Emergency Brake function can-not prevent accidents and serious injuries by itself.
• The City Emergency Brake function can carry out unwanted brake interventions in certain complex driving situations, e.g. at building sites and metal tracks.
• The City Emergency Brake can carry out unwanted braking interventions when its function is impaired, e.g. if the position of the radar sensor has been contaminated or changed.
• The City Emergency Brake function does not react to persons, animals or vehicles crossing or approaching in the same lane.

System limits
r-('n First read and observe the Introductory L-J,:.U Information and safety warnings & on page 307.
The area monitoring system (Front Assist) has physical and system-related limits. The driver may therefore feel that, in certain circumstances, some Front Assist reactions occur unexpectedly or with a delay. You should therefore always be prepared to take full control of the vehicle if necessary.
The following conditions can prevent Front Assist from reacting, or cause a delay in its reaction:
• In tight bends.
• If the accelerator is fully depressed.
• If Front Assist is switched off or there is a fault.
• If TCS or ESC is switched off manually.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the radar sensor is dirty or covered.
• If the vehicle is reversing.
• Under hard acceleration.
• In snow or heavy rain.
• In case of narrow vehicles, e.g. motorbikes.
• If vehicles are travelling slightly to the left or right of your vehicle.
• If vehicles are crossing in front of your vehicle.
• If there is oncoming traffic.
• In uncertain traffic situations.
• 1/Vhen loads or attachment parts on other vehi-cles protrude to the side, rear or above the normal dimensions of the vehicle. Lane change assist system (Side Assist)

A WARNING
The Intelligent technology of the lane change assist system (Side Assist) cannot change the laws of physics or the system-related ve-hicle limitations. Always take care when us-Ing the lane change assist system as you could otherwise cause accidents or Injuries. 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.
• Your hands should always be on the steer-Ing wheel so that you can steer at any time.
• Pay attention to the visual displays in the exterior mirror housing and in the Instrument cluster display, and respond to the com-mands.
• The lane change assist system may react to special roadside structures, e.g. high or offset crash barriers. This can lead to error warnings. ,..

A WARNING_tContlnued)
• The power steering, all driver assist sys-tems and brake assist systems will not func-tion if the engine "sputters" or stops com-pletely due to a lack of fuel or Irregular fuel supply.
• Always fill the tank when it is stlll1/4 full. This reduces the risk of running out of fuel and breaking down.
Filling the tank with petrol or diesel

Q)
• To avoid damage to your vehicle, always ob-serve the indicator lamps and associated warn-ing texts.
• Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt fuel to enter the exhaust system. The catalytic converter or diesel partlculate filter could be damaged as a result!
m The small arrow next to the petrol pump sym-L!J bol 269 shows you which side of the vehicle the tank flap is located on. • The fuel tank is full when the (properly operat-ed) automatic filler nozzle clicks off for the first time
• Do not continue filling the tank after it switches off. The expansion space in the fuel tank will other-wise fill up and the fuel could spill out. This could also happen when the fuel warms up and expands.
Closing the tank cap
• Turn the tank cap clockwise into the fuel filler neck until it perceptibly engages.
• Close the tank flap so that it engages audibly. The tank flap must be flush with the vehicle body-work.
• Close left-hand front door.
A WARNING
Do not continue filling the tank once the filler nozzle stops automatically. The fuel tank could be overfilled. This can cause fuel to splash out and overflow. This can cause fires, explosions and serious Injuries.
Q)
Remove spilt fuel from the vehicle paint as quickly as possible in order to avoid damage to the wheel housing, tyres and vehicle paint.
Spilt fuel can pollute lhe environment.
