x Tap on the Assistants button in the display.
x Select ACC.
x Tap on the Driving profiles button in the display and select driving profile.
DANGER
Following other vehicles too closely increases the risk of collisions and serious personal injury or even death.
x Always obey applicable traffic laws when setting the distance to the vehicles ahead in traffic.
x Setting short distances to the traffic ahead reduces the time and distance available to bring your vehicle to a safe stop and makes it even more necessary to pay close attention or traffic.
x Always use good judgment and select a safe following distance for the traffic, road and weather conditions.
x Never use Adaptive Cruise Control on narrow or winding roads or under poor road condi-tions (snow, ice, streets covered with standing water or gravel, for example) or when visibility is poor, especially when it is foggy.
x Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.

WARNING
Improper use of the Adaptive Cruise Control can cause collisions, other accidents and seri-ous personal injury.
x Always remember that the Adaptive Cruise Control has limits – it will not slow the vehicle down or maintain the set distance when you drive towards an obstacle or something on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disa-bled vehicle.
x Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving towards you in your traffic lane and that it cannot detect narrow vehicles such as motorcy-cles and bicycles.
x Never drive at speeds that are too fast for traffic, road and weather conditions.
x Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive Cruise Control cannot slow or brake the vehicle safely when you follow another vehicle too closely. Always remember that the Adaptive Cruise Control has a braking power that is only about 30% of the vehicle's maximum braking ability, the automatic braking function cannot bring the vehicle to a stop.
x Never use Adaptive Cruise Control when you cannot drive safely at a steady speed, in-cluding on city streets, on winding roads or when road conditions are poor (for example, on ice, gravel, in fog, heavy rain or on wet roads that increase the risk of hydroplaning).
x The radar sensor's vision can be reduced by rain, snow and heavy road spray. These and similar conditions can prevent vehicles up ahead from being accurately detected and in some cases they may not be detected at all. Do not use ACC when the radar sensors cannot accu-rately detect vehicles moving ahead of you in traffic.
x Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construc-tion zones or in similar situations because the vehicle will automatically accelerate to the stored speed when the road ahead is clear.
x Never rest your foot on the accelerator pedal, especially when the Adaptive Cruise Control is being used because doing so will override the braking function.
x Always pay attention to traffic, especially when Adaptive Cruise Control is switched on.
x Always maintain a safe speed and distance between your vehicle and other vehicles while considering the traffic situation. This is the duty of the driver. Adaptive Cruise Control is merely an aid to the driver.
x To prevent unintended operation, always switch ACC off when it is not being used.
x It is dangerous to use the “Resume” feature when the previously set speed is too high for existing road, traffic or weather conditions.
x Always select a speed and distance to traffic ahead that is safe and appropriate under the prevailing traffic, road, weather and lighting conditions.
x Never allow the closing speed between you and other vehicles to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high, you must apply the brakes yourself to reduce the risk of a rear-end crash.
NOTICE
When the vehicle is driving at speeds lower than 20 mph (30 km/h) and the 3%4 button is pressed or the lever is moved to 2%35-%, the vehicle will be accelerated to the lowest possible speed that can be set in ACC of 20 mph (30 km/h)
The stored speed is canceled when the ignition or the ACC is switched off.

WARNING
The Forward Collision Warning system (Front Assist) technology cannot overcome the laws of physics and system-related limits. The driver is always responsible for braking in time. If the Forward Collision Warning system issues a warning, immediately apply the brake to slow the vehicle down or avoid the obstacle, depending on the traffic situation.
x Always adjust your speed and driving style to road, traffic, weather, and visibility condi-tions.
x The Forward Collision Warning system cannot prevent accidents and serious injuries on its own.
x The Forward Collision Warning system can issue unnecessary warnings in certain com-plex driving situations, for example, at traffic islands.
x The Forward Collision Warning system can issue unnecessary warnings when its function is impaired, for example, if the radar sensor is dirty or if the position of the radar sensor has been changed.
x The Forward Collision Warning system does not react to people, animals, or vehicles crossing or approaching in the same lane.
x Always be prepared to take full control of the vehicle at all times.
NOTICE
If you notice that the Forward Collision Warning system (Front Assist) doesn't work properly or the sensors are damaged, switch off the Forward Collision Warning system (Front Assist) immediately.
x Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the Forward Collision Warning system (Front Assist) checked.
If the Forward Collision Warning system (Front Assist) initiates a braking maneuver, the hydraulic braking system is under pressure. In this case the braking pedal will feel “harder” and the brake pedal travel will be shorter.
Automatic braking maneuvers can be interrupted by depressing the gas pedal or moving the steering wheel.
Deactivate the Forward Collision Warning system if it does not work as described in this chapter, for example, if multiple unwanted warnings occur. Have the system checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Temporarily switch off the Forward Collision Warning system (Front
Assist) in the following situations

The Autonomous Emergency Braking function should be deactivated by switching off the Forward Collision Warning system (Front Assist) in following situations:
x When the vehicle is being towed.
x When the vehicle is on a roller test stand.
x When the vehicle is off road, like on construction sites or on race tracks.
x When one of the sensors is defect.
x When the sensors have been damaged, like after a frontal collision accident.
x After several false alarms in a row.
x If the sensors are covered by additional parts, like auxiliary headlights.
x If the vehicle is driving on steep terrain or on or across slopes.
WARNING
Always remember that the Autonomous Emergency Braking function has limits – it will not release you from the responsibility to control and slow down your vehicle.
x The Autonomous Emergency Braking function alone cannot avoid accidents and fatal injuries.
x Under certain circumstances and complex traffic situations the Autonomous Emergency Braking function can perform unwanted braking maneuvers, like in construction sites.
x Soiled or misaligned radar sensors can lead to unwanted braking maneuvers
x The Autonomous Emergency Braking function does not react to people, animals, crossing traffic or vehicles that are approaching you on the same lane.
x Always adjust your speed and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility conditions.
x Never follow a vehicle so closely that you cannot stop your vehicle safely, under certain circumstances the automatic braking function cannot bring the vehicle to a stop in time.
x Never allow the closing speed between you and other vehicles to be so high that the Au-tonomous Emergency Braking function may not be able to slow your vehicle safely. If closing speed is too high, you must apply the brakes yourself to reduce the risk of a rear-end crash.
x Always be prepared to takeover the control of the brake and the gas pedal in every situa-tion.
NOTICE
If you notice that the Autonomous Emergency Braking function doesn't work properly or the sensors are damaged, switch off the Forward Collision Warning system (Front Assist) and therefore the Autonomous Emergency Braking function immediately.
x Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the system checked.
If the Autonomous Emergency Braking function initiates a braking maneuver, the hydraulic brak-ing system is under pressure. In this case the braking pedal will feel “harder” and the brake pedal travel will be shorter.
Automatic braking maneuvers can be interrupted by depressing the gas pedal or moving the steering wheel.
The Autonomous Emergency Braking function can slow your vehicle down to a standstill, but not hold your vehicle permanently. When necessary, apply the vehicle brakes!

WARNING
If the view area of the camera is covered or dirty, Lane Assist may not work properly.
x Always make sure that the camera area is free of dirt or snow and not covered.
NOTICE
In order to help maintain the proper function of the Forward Collision Warning system (Front Assist):
x Always keep the camera area in the front windshield free of ice, dirt and snow.
x Never cover the camera area.
x Regularly check the windshield and especially the area of the camera for damages.
Lane Assist has been developed only for on-road driving.
If Lane Assist does not work properly and as described here, have the system checked by an authorized Volkswagen dealer or Volkswagen Service Facility.

Warning and indicator lights

Radar sensors
The Side Assist radar sensors are located on the left and right side above the rear bumper ⇒ fig. 281. They cover an area of about 50 m (160 ft) behind your vehicle as well as the blind spots on the left and right vehicle side. On the left and right side of your vehicle Side Assist covers an area of about the width of one driving lane.
However, Side Assist does not recognize the exact width of the driving lanes next to your vehicle. In some cases, such as driving in the middle of 2 lanes or with very narrow lanes, this can lead to an incorrect indication. In other cases, vehicles moving on further driving lanes like the second to left lane, or even fixed objects, such as guide rails, can cause the indicator lights to light up.
