Adaptive Cruise Control (ACC)
Introduction
This chapter contains information on the followingsubjects:
⇒ Special driving situations 
⇒ Limits of ACC 
⇒ Switching ACC on and off 
⇒ Setting ACC 
⇒ Troubleshooting 
The Adaptive Cruise Control (ACC) maintains a speed selected by the driver. If the vehicle
approaches a vehicle in front, the ACC automatically adapts the speed so that a distance you have
selected is maintained.
Speed range
ACC controls the vehicle in the speed range between 30 km/h (20 mph) and 160 km/h (100 mph)
or 210 km/h (130 mph). This speed range may differ in certain markets.
Driving with ACC
You can override the ACC at any time. Control will be interrupted when you brake. If you accelerate,
control will be interrupted for the duration of the acceleration process and will then continue again.
Control by ACC is less dynamic when towing a trailer ⇒  . The ACC will not perform control operation
if the trailer's brake lights are faulty.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can make settings for ACC in the vehicle settings of the
Infotainment system ⇒ Vehicle settings menu .
Brake request

If automatic deceleration by ACC is not sufficient, ACC will request you to brake additionally by a
corresponding message on the instrument cluster. In addition, the red warning lamp lights up
and an acoustic warning is given. Brake immediately!
Radar sensor
ACC detects driving situations by means of the radar sensor at the front of the vehicle ⇒ Front view .
The radar sensor has a range of up to approximately 120 m.

WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only
within the limits of the system. Never let the extra convenience tempt you into taking safety risks
when driving. Careless or unintentional use of the Adaptive Cruise Control (ACC) can cause accidents
and lead to serious 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.
Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due
to snow, ice, wet roads, loose chippings, or on flooded roads.
Never use the ACC offroad or on non-surfaced roads. The ACC is designed for use on surfaced roads
only.
The ACC will not react to stationary vehicles.
The ACC will not react to persons, animals or vehicles crossing or approaching in the same lane.
Brake immediately if speed reduction by ACC is not sufficient.
Brake immediately if a request to brake appears on the instrument cluster display.
Brake if the vehicle starts rolling unintentionally after a request to brake.
Be prepared to control the speed yourself at all times.
Special driving situations

Fig. 118 On the instrument cluster display: slower vehicle detected in the left-hand lane (illustration).

First read and observe the introductoryinformation and safety warnings⇒Introduction 
Overtaking
If you indicate left (left-hand traffic: indicate right) to overtake, ACC will accelerate the vehicle and
reduce the distance from the vehicle in front. Your set speed will not be exceeded.
If ACC does not detect any vehicle in front after you have changed lane, ACC will accelerate the
vehicle up to the set speed.
Stop-and-go traffic
ACC can brake vehicles with DSG® dual clutch gearbox to a standstill and hold them stationary. ACC
remains active and the instrument cluster display shows ACC ready for a few seconds. During this
time the vehicle will move off again automatically as soon as the vehicle in front moves off
(depending on the vehicle equipment level and not available in all countries).
Press the button.
Press the button or briefly press the accelerator.
The vehicle is stationary for longer than approximately three minutes.
A vehicle door is opened.
The ignition is switched off.
Avoiding overtaking on the right (left-hand traffic: overtaking on the left)
If ACC detects a slower vehicle in the left-hand lane (left-hand traffic: in the right-hand lane), ACC
will brake the vehicle gently within the system limits and therefore prevent a prohibited overtaking
manoeuvre ⇒ Fig. 118 . The function is active from speeds of around 80 km/h (50 mph), but is not
available in all countries.

WARNING
If the message ACC ready is shown on the instrument cluster display and the vehicle in front moves
off, your vehicle will move off automatically. In some cases the radar sensor may be unable to detect
obstacles that are located in the vehicle's path. This can result in serious injury and accidents.
Always check the road ahead before moving off and brake the vehicle if necessary.

ACC stores the current speed and maintains the set distance. If the current speed is outside the
defined speed range, ACC will set the minimum speed (when driving more slowly than the limit) or
maximum speed (when driving faster than the limit).
The following indicator lamps light up, depending on the driving situation:
ACC regulating.No vehicle has been detected ahead.Vehicle detected ahead (white).
Interrupting control
Briefly press the button or press the brake pedal.
The indicator lights up grey, the speed and distance remain stored.
Control is automatically interrupted if the traction control system (TCS) is deactivated.
Resuming control
Press the button.
ACC adopts the last set speed and last set distance. The instrument cluster display shows the set
speed and the indicator lamp lights up green.
Switching off ACC
Press and hold the button.
The set speed is deleted.
Changing to the speed limiter
Press the button.
ACC is switched off.
Setting ACC

WARNING
If you do not maintain the minimum distance to a vehicle in front and the difference in speed
between the vehicle in front and your own vehicle is so great that the braking action of the ACC is
insufficient, you are in danger of colliding with the vehicle in front. The braking distance is also
longer in rain and winter road conditions.
ACC may not be able to detect all driving situations correctly.
Always be prepared to brake the vehicle yourself.
Speed and distance control are overridden when you press the accelerator. ACC does not brake
automatically in this case.
Observe any country-specific regulations relating to the minimum distance.
Always set a larger distance in wet or snowy conditions or when visibility is poor.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .

Area monitoring system (Front Assist)
Introduction
This chapter contains information on the followingsubjects:
⇒ Warning levels and braking intervention 
⇒ Limits of Front Assist 
⇒ Pedestrian Monitoring 
⇒ Operating the area monitoring system (Front Assist) 
⇒ Troubleshooting 
The area monitoring system (Front Assist) with City Emergency Braking System and Pedestrian
Monitoring can help to avoid accidents.
Within the limits of the system, Front Assist can warn the driver about imminent collisions, prepare
the vehicle for emergency braking, assist with braking, and initiate automatic braking. The warning
time varies depending on the traffic situation and driver behaviour.
Front Assist is not a substitute for the full concentration of the driver.
Driving with Front Assist
You can cancel the automatic braking interventions of Front Assist by steering or pressing the
accelerator.
Automatic braking
Front Assist can decelerate the vehicle to a standstill. The vehicle will then not be held permanently.
Depress the brake pedal.

The brake pedal will feel harder during an automatic braking operation.
Radar sensor
Front Assist detects driving situations by means of the radar sensor at the front of the vehicle
⇒ Front view . The radar sensor has a range of up to approximately 120 m.
Functions included in the system
The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle equipment)
are part of Front Assist and are automatically active when Front Assist is switched on.

WARNING
The intelligent technology used in Front Assist cannot overcome the laws of physics, and functions
only within the limits of the system. Never let the extra convenience afforded by Front Assist tempt
you into taking safety risks when driving. The driver is always responsible for braking in time.
If Front Assist issues a warning, brake your vehicle immediately depending on the traffic situation or
avoid the obstacle.
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 warnings and carry out unwanted braking interventions in certain
complex driving situations, e.g. at traffic islands.
Front Assist can issue unnecessary warnings and carry out unwanted braking interventions when its
function is impaired, e.g. if the radar sensor is dirty or its position has been changed.
Front Assist without Pedestrian Monitoring does not react to persons. In addition, the system does
not react to animals or to vehicles that are crossing or approaching in the same lane.
If you are unsure whether your vehicle possesses Pedestrian Monitoring, please enquire about this
at a qualified workshop before starting your journey.
Be prepared to take over control of the vehicle yourself at all times.
Warning levels and braking intervention
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Distance warning
The system detects when safety is endangered by driving too close to the vehicle in front. The
warning lamp lights up. Increase the distance.
Speed range: around 65 km/h (40 mph) to 250 km/h (155 mph).
Advance warning

The system is able to detect possible collisions with vehicles in front or pedestrians crossing in front
of the vehicle and prepares the vehicle for a possible emergency braking procedure.
A warning tone sounds and the red warning lamp lights up. Brake or take avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
Urgent warning
If the driver does not react to the advance warning, the system may initiate a short braking jolt in
order to draw attention to the increasing collision risk. Brake or take avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
Automatic braking
If the driver also does not react to the urgent warning, the vehicle can be braked automatically with
braking force that increases in several stages. The reduced speed means that it is possible to
minimise the consequences of an accident.
Speed range: around 5 km/h (3 mph) to 250 km/h (155 mph).
Braking intervention
If the system detects that the driver is braking insufficiently when there is a risk of collision, the
system can increase the braking force and help prevent a collision. The braking intervention takes
place only for as long as the brake pedal is pressed hard.
Speed range: around 5 km/h (3 mph) to 250 km/h (155 mph).
City Emergency Braking System
The City Emergency Braking System is part of Front Assist. If the driver does not react to a possible
collision, the system can also automatically brake the vehicle with increasing braking force without
any advance warning.
The red warning lamp lights up
Speed range: around 5 km/h (3 mph) to 30 km/h (20 mph).
Limits of Front Assist
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Front Assist is not available or its functions are restricted for a period of around 30 seconds (also
longer, depending on the driving situation) immediately after the vehicle is started.
Front Assist has physical and system-related limitations. You should therefore always be prepared to
take full control of the vehicle if necessary.
Delayed response
If the radar sensor is exposed to environmental conditions that impair sensor functioning, the
system may detect this only after a certain time. For this reason, possible functional restrictions may
be displayed only after a delay at the start of the journey and when driving ⇒ .
