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.

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.

Switch on the ignition.
Push the infotainment button CAR.
Tap on the Assistants button in the display.
Select ACC.
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.
Always obey applicable traffic laws when setting the distance to the vehicles ahead in
traffic.
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.
Always use good judgment and select a safe following distance for the traffic, road and
weather conditions.
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.
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.
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.
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 drive at speeds that are too fast for traffic, road and weather conditions.
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.
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).
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.
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.
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.
Always pay attention to traffic, especially when Adaptive Cruise Control is switched on.
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.
To prevent unintended operation, always switch ACC off when it is not being used.
It is dangerous to use the “Resume” feature when the previously set speed is too high for
existing road, traffic or weather conditions.
Always select a speed and distance to traffic ahead that is safe and appropriate under the
prevailing traffic, road, weather and lighting conditions.
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  button is pressed
or the lever is moved to , 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.

The Electronic Stabilization Program (ESC) cannot be deactivated when the Adaptive Cruise
Control is switched on. If the ESc has been deactivated and you then switch on the Adaptive Cruise
Control, the ESC function will also be activated automatically.
The currently set distance and the last settings are stored automatically and assigned to the used
remote control vehicle key.
When to temporarily deactivate Adaptive Cruise Control (ACC)
Please first read and note the introductory information and heed the WARNINGS
Please deactivate ACC under following conditions ⇒ :
When driving around curves, turn lanes, highway ramps or construction sites, in order to prevent
unwanted acceleration of the vehicle.
When driving through tunnels.
Under bad weather conditions or bad visibility, like in heavy rain, snowfall or fog.
WARNING
Not deactivating Adaptive Cruise Control (ACC) in the situations mentioned above can cause
collisions, other accidents and serious personal injury.
Forward Collision Warning system (Front Assist)
Fig. 274 In the instrument cluster display. Advance warning: Distance to vehicle ahead becoming too small.

Fig. 275 In the instrument cluster display. Alert: Distance to vehicle ahead is too small.
Please first read and note the introductory information and heed the WARNINGS
The Forward Collision Warning system (Front Assist), when switched on, uses a radar sensor to help
prevent rear-end collisions by providing a warning of a possible collision with a vehicle on the road
ahead within physical and technical limits of the system.
The Forward Collision Warning system (Front Assist) is not a substitute for the driver's full
concentration.
Distance warning
If the vehicle is traveling within a speed range of about 44–130 mph (70–210 km/h), the system warns
the driver with a message in the instrument cluster display ⇒ fig. 275 if it detects that the vehicle is
driving too close to the vehicle ahead ⇒ .
The warning period varies according to the traffic situation and your driving style.
Advance warning
If the vehicle is traveling within a speed range of about 18–130 mph (30–210 km/h), the system warns
the driver with a warning chime and a message in the instrument cluster display (⇒ fig. 274) if it de-
tects a possible collision with a vehicle ahead ⇒ .
The warning period varies according to the traffic situation and your driving style.
However, do not rely solely on Front Assist. Under certain conditions, the reactions of Front Assist
may be unexpected or delayed from the driver's viewpoint. Always pay attention and take over if
necessary ⇒ .
Immediate warning
Front Assist can initiate a short active braking maneuver, should you not react accordingly to an ad-
vance alert. In this case you will notice brief jerky braking of the vehicle, in order to warn you of an
impending collision.
The moment of this alert can vary, depending on the traffic situation and the driving behavior.
Automatic braking maneuver
If you should also fail to react to the immediate alert, the system can initiate an automatic braking
maneuver which will slow down the vehicle with gradually increasing braking force. Shortly before a
collision the system can also initiate an emergency braking in order to bring the vehicle to a full stop.
The reduction of speed can help to minimize the effects of a collision.
Braking support
Front Assist can help to minimize the effects of a collision by supporting with additional braking force in
case of an emergency braking situation, should the system detect that the force applied to the brake
pedal by the driver is not sufficient in order to avoid a collision. In order for Front Assist to apply this
support, it must have detected an impending collision with another vehicle ahead of yours and the

brake pedal has to be hit hard and suddenly. However, this support only works as long as the brake
pedal is depressed.
Front Assist cannot react when approaching standing objects ahead of you, like when driving up to a
line of stopped vehicles in heavy traffic.
Operating Front Assist
Front Assist can be turned off or on in the infotainment system:
Switch on the ignition.
Push the infotainment button CAR.
Tap on the Assistants button in the display.
Select Front Assist.
Tap on the Active button in order to switch Front Assist on or off.
If the box next to the Active button is checked , then Front Assist is active and ready.
If Front Assist is switched off, then the message Front Assist deactivated appears in the
display of the instrument cluster.
With Front Assist switched off, the advance alert and the distance alert are also deactivated.
Switching the advance alert and distance alert on and off
The advance alert and distance alert can be activated or deactivated together in the infotainment
system:
Switch on the ignition.
Push the infotainment button CAR.
Tap on the Assistants button in the display.
Select Front Assist.
Tap on the Alert button in order to switch advance alert and distance alert on or off.
If the box next to the Active button is checked , then advance alert and distance alert are active and
ready.
Volkswagen recommends to always leave the advance alert and distance alert activated.
Special driving situations
Front Assist is subject to physical and system-specified limits when driving. Under certain conditions,
the reactions of the Adaptive Cruise Control may be unexpected or delayed from the driver's viewpoint

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.
Always adjust your speed and driving style to road, traffic, weather, and visibility condi-
tions.
The Forward Collision Warning system cannot prevent accidents and serious injuries on
its own.
The Forward Collision Warning system can issue unnecessary warnings in certain com-
plex driving situations, for example, at traffic islands.
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.
The Forward Collision Warning system does not react to people, animals, or vehicles
crossing or approaching in the same lane.
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.
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
Please first read and note the introductory information and heed the WARNINGS
The Forward Collision Warning system (Front Assist) should be switched off in the following situations
due to system limitations ⇒ :
If the vehicle is being towed.
If the vehicle is on a dynamometer test bed.
If the vehicle is not being driven on public roads, for example, off-road or on a track.

If the radar sensor malfunctions.
If external force has affected the radar sensor, for example, after a rear-end collision.
If the radar sensor is covered (even temporarily) by any accessories or other equipment, for exam-
ple, auxiliary headlights.
If the vehicle is being loaded onto a truck, ferry, or train.
WARNING
Failure to switch off the Forward Collision Warning system in the situations mentioned can
cause accidents and serious personal injury.
Forward Collision Warning system (Front Assist) system limits
Please first read and note the introductory information and heed the WARNINGS
The Forward Collision Warning system (Front Assist) has physical and system-related limits. The
driver may therefore feel that, in certain circumstances, some Forward Collision Warning system
reactions are unwanted or occur with a delay. You should therefore always be prepared to take full
control of the vehicle whenever necessary.
The following conditions can prevent the Forward Collision Warning system (Front
Assist) from reacting, or delay its ability to react:
When driving in tight curves.
When the accelerator pedal is depressed.
When the Forward Collision Warning system (Front Assist) is switched off or if there is a fault.
When ASR is manually switched off.
When the ESC is taking corrective action.
When several brake lights on the vehicle or on a trailer connected to the vehicle electrical system
are faulty.
When the radar sensor is dirty or covered.
When there are metal objects, for example, tracks or metal plates in the road.
When the vehicle is in Reverse (R).
When weather conditions are poor.
When narrow vehicles, such as motorcycles, are moving in front of your vehicle.
When vehicles are traveling slightly offset to the left or right in front of your vehicle.
When vehicles are crossing in front of your vehicle.
When there is oncoming traffic.
When the system cannot detect the traffic situation clearly.
When loads or attachment parts on other vehicles in front of your vehicle protrude to the side, rear,
or above the normal vehicle dimensions.

Autonomous Emergency Braking
Fig. 276 In the instrument cluster display. Warning: Distance to vehicle ahead becoming too small.
Please first read and note the introductory information and heed the WARNINGS
Autonomous Emergency Braking is a function of the Forward Collision Warning system (Front Assist)
and active when the Forward Collision Warning system (Front Assist) is switched on.
The Autonomous Emergency Braking function monitors the traffic situation in front of your vehicle at
speeds between 3 mph (5 km/h) and about 20 mph (30 km/h).
If the Autonomous Emergency Braking function detects a critical situation which can lead to a collision,
it will prepare the vehicle for a possible emergency braking maneuver ⇒ .
In case of an impending collision and the driver not reacting accordingly to the warning, the system
can initiate an automatic braking maneuver in order to reduce the speed of your vehicle and help
minimize the effects of a collision.
Display
An automatic braking maneuver is indicated by a warning in the instrument cluster display ⇒ fig. 276.
The Autonomous Emergency Braking function may not work under following conditions:
When driving around curves.
When the Forward Collision Warning system (Front Assist) is switched off or not working properly.
When ASR is switched off manually.
When ESC is actively regulating.
When 2 or more brake lights on your vehicle are not working.
When the sensors are soiled or covered.
When the brake pedal is depressed.
When the OFF-ROAD mode is switched on.
If the last braking maneuver initiated by the Autonomous Emergency Braking function is shorter
than 20 seconds ago.
When your vehicle is driving in reverse.
When your vehicle is quickly accelerated.
In bad weather conditions with decreased visibility, like heavy rain or snowfall.
If the vehicles travelling ahead are too small or narrow, like motorcycles or bicycles.
If the vehicles travelling ahead are driving offset.
If the radar sensor signal is multiply reflected, like when driving in parking garages.
In case of crossing traffic.
In case of oncoming vehicles on your lane.

The Autonomous Emergency Braking function should be deactivated by switching off
the Forward Collision Warning system (Front Assist) in following situations:
When the vehicle is being towed.
When the vehicle is on a roller test stand.
When the vehicle is off road, like on construction sites or on race tracks.
When one of the sensors is defect.
When the sensors have been damaged, like after a frontal collision accident.
After several false alarms in a row.
If the sensors are covered by additional parts, like auxiliary headlights.
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.
The Autonomous Emergency Braking function alone cannot avoid accidents and fatal
injuries.
Under certain circumstances and complex traffic situations the Autonomous Emergency
Braking function can perform unwanted braking maneuvers, like in construction sites.
Soiled or misaligned radar sensors can lead to unwanted braking maneuvers
The Autonomous Emergency Braking function does not react to people, animals, crossing
traffic or vehicles that are approaching you on the same lane.
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 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.
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.
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.
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!

Should the Autonomous Emergency Braking function not work properly as described here and
initiate several false alarms unwanted braking maneuvers in a row, temporarily deactivate the Forward
Collision Warning system (Front Assist) and therefore the Autonomous Emergency Braking function.
Have the system checked by an authorized Volkswagen dealer or Volkswagen Service Facility.

Please first read and note the introductory information and heed the WARNINGS
Adaptive Cruise Control is subject to physical and system-specified limits when driving. Under certain
conditions, the reactions of the Adaptive Cruise Control may be unexpected or delayed from the
driver's viewpoint. Always pay attention and take over if necessary:
Changing lanes and passing other vehicles
When you change lanes, like when passing a vehicle ahead of you, and there is no other vehicle
detected on the lane that you switched to, ACC will automatically accelerate your vehicle to the previ-
ously set speed.
Driving around curves and roundabouts
When driving into a curve and driving out of a long curve, the radar sensor may react to a vehicle in
the next lane ⇒ fig. 277 (A) and cause your vehicle to brake. You stop the braking process by pressing
the accelerator pedal.
When driving in curves and roundabouts it can happen that the vehicle travelling ahead of yours
temporarily leaves the sensor range of your vehicle. This can lead to an unwanted acceleration of your
vehicle. Switch off ACC in narrow curves and roundabouts.
Driving through tunnels
The function of the distance radar may be limited when driving in tunnels. Switch off ACC when driving
through tunnels.
Vehicles offset to one side
Vehicles traveling ahead and to one side can only be detected by the radar sensor when they are
within sensor range (B). That applies especially to narrow vehicles such as motorcycles.
