The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal. The status where the CCS maintains the speed
is referred to hereinafter as the control.

Introduction
This chapter contains information on the following subjects:
Operation
109
Description of operation

The Speed Limiter limits the maximum driving speed to the set speed limit.
This limit can only be exceeded by depressing the accelerator pedal fully.
The condition in which the Speed Limiter monitors a potential set speed limit
excess is referred to as Regulation.

warning light lights up in the instrument cluster.
Exceeding the speed limit during the regulation
If, during the setting, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.

The Adaptive Cruise Control (hereinafter referred to as ACC) maintains the set
speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 100.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railway tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

The ACC allows a speed of 30-160 km/h to be set or a distance to the preced-
ing vehicle to be very short of very long to be set.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, the
warning light lights up in the instrument cluster and the display shows a
message to engage the brake pedal.
1234NoteSome ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.
Automatic stop-start
Read and observe
on page 110 first.
Vehicles with an automatic transmission can decelerate to a complete stop
and start moving again using the ACC.
Decelerate to a complete stop
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a complete stop.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be controlled. Control is
automatically disconnected in case of longer holding periods.

Basic requirements for start of control The ACC is activated.
On vehicles with manual transmission , the second gear or a higher gear is
selected and the current speed is greater than 25 km/h.
On vehicles with automatic transmission the selector lever is in the posi-
tion D / S or in the Tiptronic position and the current speed is higher than

The ACC takes the current driving speed and performs the control, the warning
light illuminates in the instrument cluster.
If the control is started by moving the lever to the position and should
the speed be stored already, the ACC adopts this speed and executes control.
Note
If control is started at a speed of less than 30 km/h on vehicles with an auto-
matic transmission, the speed of 30 km/h is stored. The speed increases auto-
matically to 30 km/h or is regulated with respect to the speed of the vehicle
ahead.

resumed.■
If during control the speed is reduced by applying the brake, control is stop-
ped. Control needs to be restarted in order to resume » page 112.
■
If the vehicle is controlled by a lower speed than the stored speed, then
the current speed is stored by pressing the button again
and the speed is
reduced in increments of 1 km/h.
112Driving

Overtaking and towingRead and observe
on page 110 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the vehi-
cle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 142 on page 111 .
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.
Malfunctions
Read and observe
on page 110 first.
If, for some unknown reason, ACC is not available, the warning light appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor is dirty or covered, a message indicating that there is no sensor
view appears. Clean the sensor cover or remove the obstacles » Fig. 125 on
page 100 .
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.

The Front Assist (hereinafter referred to as "system") warns you of the danger
of a collision with a vehicle or another obstacle in front of the vehicle, and tries
to avoid a collision or mitigate its consequences by automatically applying the
brakes where necessary.
The area in front of the vehicle is monitored by a radar sensor » page 100.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The system does not respond to crossing or oncoming objects.
CAUTION
In case of failure of more than one brake light on the vehicle or on the electri-
cally connected trailer, the system becomes unavailable.
Operation
Read and observe
and on page 114 first.
The system support is provided in the following manner.▶ Alerts you about a dangerous proximity to the vehicle ahead.
▶ Warns you of an impending collision.
▶ Assists with a brake action triggered by the driver.
▶ If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system can work only if the following basic conditions are met. The system is activated.
TCS is activated » page 102.
