If no speed limit is set, the current speed is set as the speed limit.
At the start of the regulation, the current speed is set as the speed limit and
displayed in the instrument cluster display. The warning light illuminates in
the instrument cluster.
Exceeding the speed limit during the regulation
If exceeding the speed limit is required during the regulation, for example
when overtaking, then the accelerator pedal is to be fully pressed.
When exceeding the speed limit, an acoustic signal sounds and the warning
light in the instrument cluster flashes.
The regulation is resumed once the speed has fallen below the set limit.
CAUTIONWhen driving downhill, exceeding the set speed limit may occur. When exceed-
ing the limit, an acoustic signal sounds and the warning light in the instru-
ment cluster flashes.

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 143.
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 142, in section Introduction .■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, in the instrument cluster, the warning light lights up and the display shows the
following message.Apply the brake!
Regulation according to the vehicle in the adjacent lane
During regulation your vehicle may be regulated according to the vehicle in the adjacent lane.
This could occur at speeds above about 80 km / h when your vehicle is moving
faster than the vehicle in the adjacent lane on the driver's side. The display
shows the detected vehicle is in the adjacent lane.
Note
Some 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 163 first.
Vehicles with an automatic transmission can decelerate to a standstill and
start moving again using the ACC.
Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a standstill.
34Starting 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 regulated.
If the preceding vehicle starts moving again after a long break, then to contin-
ue the regulation press the accelerator pedal or lever to position

The ACC will adopt the current speed and execute control. Should the speed be stored already, the ACC adopts this speed and executes control.
The warning light illuminates in the instrument cluster when the regulation
is switched on.
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.■
When TCS is disabled, it will be activated automatically upon starting control.

■
If the proximity is changed in infotainment, the change will only come into

The proximity is dependent on the speed. The higher the speed, the greater
the proximity to the vehicle ahead.

On wet roads, a longer time interval to the vehicle ahead should always be
selected than on dry roads.
Special driving conditionsFig. 205
Special conditions: Cornering / narrow vehicles or vehicles trav-
elling side by side
Fig. 206
Special conditions: Lane changes of other vehicles / stationary
vehicles
Read and observe
on page 163 first.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adja-
cent lane » Fig. 205 -
. Your own vehicle is regulated with respect to this ve-
hicle and will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever
» Fig. 204 on page 165 .
167Assist systems
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the ra-
dar sensor until they are within the sensor's range » Fig. 205 -
.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 206 -
do not
have to be detected by the radar sensor in time. The result may be a delayed
ACC response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehicle,
» Fig. 206 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and stop the vehicle by applying the foot
brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is
stored) and the indicator is activated, the ACC interprets this situation as
meaning that the driver intends to overtake. The ACC automatically acceler-
ates the vehicle, thereby reducing the proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the
ACC accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 204 on page 165 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or over-
taking such a vehicle.
Towing a trailer
When towing, or in when another accessory is connected to the trailer socket
the ACC control is set with a lower rate. The manner of driving should there-
fore be adapted to this limitation.Information messages

With automatic braking the symbol appears » Fig. 208 in the display.
Advance warning
If the system detects a risk of collision, the symbol
» Fig. 208 appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.

Adaptive Chassis Control (DCC)
Read and observe
on page 171 first.
The adaptive chassis control (following known as DCC) provides the ability toadjust the shock characteristics for the sporty, normal or comfortable driving
when the corresponding control mode is selected.
The DCC evaluates steering response and road conditions while driving contin-
uously and adjusts the suspension behaviour within the selected driving mode
accordingly.
