Adaptive Cruise Control (ACC) with Front Assist
Introduction
In this section you’ll find information about:
Display, warning and indicator lights
Radar sensors, ultrasonic sensors and Front Assist camera
Switching ACC on and off
When to temporarily deactivate Adaptive Cruise Control (ACC)
Forward Collision Warning system (Front Assist)
Temporarily switch off the Forward Collision Warning system (Front Assist) in the following
situations
Forward Collision Warning system (Front Assist) system limits
Autonomous Emergency Braking
Special driving situations
The Adaptive Cruise Control system (ACC) helps maintain an individually stored constant speed
between about 20 mph (30 km/h) and 95 mph (150 km/h) and a previously set distance in time inter-
vals between your vehicle and those in front of you.
ACC uses radar, ultrasonic and video sensors installed on your vehicle. Moving vehicles in front of
yours can be detected within a distance of up to 590 ft (180 m).
The vehicle may be braked, if the situation so requires, to a standstill by an active braking maneu-
ver ⇒  .
Adaptive Cruise Control has system-specified limits. As a driver, you must control the speed and the
distance to other vehicles under some circumstances. If that is necessary, the system requests the
driver to take over using a visual and audible warning.
How does Adaptive Cruise Control (ACC) work?
Adaptive Cruise Control requires you to set the desired speed and distance. Set and adjust the speed
using the lever to the left of the steering column. Set the distance using the sliding switch on top of the
lever.
Driver intervention warning
Adaptive Cruise Control has system-specified limits. As a driver, you must control the speed and the
distance to other vehicles under some circumstances. If that is necessary, the system requests the
driver to take over using a visual and audible warning ⇒ table on page 461, even if the vehicle can be
braked to a standstill by an active braking maneuver.
More information:
Exterior views
Shifting
Parts, accessories, repairs and modifications
Cruise Control system CCS
WARNING
Always remember that the Adaptive Cruise Control has limits – Using Adaptive Cruise Con-
trol when it is not possible to drive safely at a constant speed can be dangerous and can lead
to an accident and serious personal injury.
Adaptive Cruise Control 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 disabled vehicle.
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.
Never use Adaptive Cruise Control on steep, winding, or slippery roads (such gravel
roads, wet roads, or snowy or icy roads) or on roads with standing water.
Never use Adaptive Cruise Control when driving in heavy or varying stop-and-go traffic.
Never use Adaptive Cruise Control when driving off-road or on unpaved roads.
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.
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, under certain circumstances the auto-
matic braking function cannot bring the vehicle to a stop in time.
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.
To help prevent unintended operation of Adaptive Cruise Control, switch the system off
when it is not being used.
It is dangerous to use the Resume feature when the previously set speed is too high for
the existing road, traffic, or weather conditions.
When traveling downhill, the Adaptive Cruise Control may not be able to maintain a con-
stant speed. The vehicle will speed up because of its own weight. Downshift and/or use the
foot brake to slow the vehicle.
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.
If a driver intervention warning appears in the instrument cluster display, immediately
takeover the control of the brake and gas pedals and low down the vehicle or bring it to stop
when necessary and according to the traffic situation.
If a Forward Collision Warning system (Front Assist) collision warning appears in the
instrument cluster display, immediately takeover the control of the brake and gas pedals and
low down the vehicle or bring it to stop when necessary and according to the traffic situation.
Always be prepared to takeover the control of the brake and the gas pedal in every situa-
tion.
NOTICE
If you suspect that ACC and the Forward Collision Warning system (Front Assist) don't work
properly or the sensors are damaged, switch off ACC immediately.
Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and
have the ACC system checked.

Radar sensors, ultrasonic sensors and Front Assist camera
Fig. 271 Vehicle front view: Sensors and camera
Please first read and note the introductory information and heed the WARNINGS
Key to ⇒ fig. 271:
(1) Camera for Front Assist system
(2) Ultrasonic sensors for the Adaptive Cruise Control (ACC)
(3) Radar sensors for the Adaptive Cruise Control (ACC) and Front Assist
There are 2 radar sensors next to the fog lights on the vehicle front (3). These can detect moving
vehicles up to 590 ft (180 m) in front of your vehicle.
The areas of the sensors (2) and (3) and the camera (1) must not be spray painted on or covered by
stickers or other objects, since this can lead to a malfunction of the Adaptive Cruise Control (ACC) and
the Front Assist system.
NOTICE
If you notice that Adaptive Cruise Control (ACC) or Front Assist doesn't work properly or the
sensors are damaged, switch off ACC immediately.
Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and
have the ACC system checked.
The sensors can be damaged or become misaligned in low speed impacts and parking
maneuvers. Damaged or misaligned sensors can cause ACC or Front Assist to malfunction.
To help make sure that the system works properly, always keep the sensors clean, free of
snow and ice; do not cover the sensors with stickers or other objects.
When cleaning the sensors with power washers or steam cleaners, only spray the sensors
directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from
the sensors.
For Declaration of Compliance to United States FCC and Industry Canada regulations
Always keep the area of the Front Assist camera clear of ice and snow.

Requirements for activating ACC
Lever is in the  (1) position.
The selector lever must be in D, Sor in Tiptronic mode.
Gradient angles can't be more than +/- 19 %.
Brake pedal is depressed when vehicle is standing still.
the driver safety belt is fastened.
The doors and the engine hood are closed.
The electronic parking brake is released
Hill Descent Assist is not activated.
The vehicle is not rolling backwards.
There is no parked vehicle or other object in front of your moving vehicle.
Activating ACC
When ACC is active one of the 2 green indicator lights (or ) light up and the set speed is shown in
the display of the instrument cluster and indicated by red dots on the speedometer. Text messages
and indicator lights in the instrument cluster inform you about the status of the system ⇒ page 459.
When ACC is switched, activated and properly working, it will store and regulate the desired speed.
The set speed can vary from the actually driven speed if ACC is regulating the distance to the vehicle
travelling ahead.
Decelerating to a stop
If a vehicle ahead decelerates to a stop the Adaptive Cruise Control likewise decelerates your vehicle
to a standstill. After this vehicle is kept in place by the brakes.
In this state using the brake does not deactivate the Adaptive Cruise Control.
If you unlock the safety belt, open the a door or the engine hood, switch off the ignition during such a
braking state or if the stop exceeds about three minutes, the Adaptive Cruise Control switches off
temporarily and activates the parking brake.
By depressing the gas pedal while the vehicle is standing still and ACC is active, the vehicle will ac-
celerate. Once you take your foot off the pedal, ACC will automatically resume the stored speed and
regulate the set distance.
ACC will not automatically accelerate if the vehicle ahead accelerates.
Distance (time interval) to the vehicle ahead and driving profiles
The distance the ACC maintains to the vehicle traveling ahead is determined by time intervals. A time
distance to the vehicle traveling ahead is maintained. This results in a speed-dependent distance. The
higher the speed, the larger the distance in feet/meters ⇒  .
The distance can be set at 4 different levels:
Distance Time distance at 65 mph
(105 km/h)
Very small about 1,0 Seconds
Small about 1,3 Seconds
Medium about 1,8 Seconds
Large about 2,5 Seconds
Besides changing the time distance, the acceleration characteristics can be changed, by choosing on
of the following driving profiles:
Comfort
Normal
Sport
The distance intervals can be set by pushing the slider switch on the lever ⇒ fig. 273. The driving
profile can only be set in the infotainment system .
Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.
Setting the distance and selecting a driving profile
In order to show the currently selected distance in the instrument cluster display, briefly tap the sliding
switch on the lever ⇒ fig. 273.
