Automatic brake assist when speeding
If a velocity of 7 km / h is exceeded during the parking manoeuvre for the first
time, the speed will be automatically reduced by the system to less than 7 km /
h. This prevents the parking manoeuvre from aborting.
Automatic emergency braking
If the system detects a risk of collision during parking, automatic emergency
braking takes place to prevent a collision.
The parking is terminated by the emergency braking.
CAUTION
The automatic emergency braking is not triggered by the system when the

Operation description

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.

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).
163Assist systems
WARNING (Continued)■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).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
■
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.
OperationFig. 202

Read and observe
on page 163 first.
The ACC allows you to set a speed of 30 - 160 or 210 km / h (depending on
equipment) and the distance to the vehicle ahead in the range of a very short
to a very long distance.
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. 150 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, 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 is activated.
The vehicle is moving at a speed other than that which is stored.
Note
■
If during control the speed is increased by pressing the accelerator, control is
temporarily stopped. Upon releasing the accelerator, control is automatically
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 166.
■
If the vehicle is controlled by a lower speed than the stored speed, then
the current speed is stored the first time the key is pressed. Press the key
again
and the speed is reduced in increments of 1 km/h.

Note
■
If the proximity is changed in infotainment, the change will only come into
effect after a subsequent activation of the ACC.■
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.

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
