Park Assist (following referred to system) helps drivers park in suitable parallel
and perpendicular parking places or also to manoeuvre out of parallel parking
spaces.
The system takes over the steering movements only when parking or leaving a
parking space. The driver operates the brake, accelerator or clutch pedal and
the shift / selector lever.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The Park Assist is an extension of the parking aid » page 215 and operates on
the basis of data collected by the ultrasonic sensors.
For this reason, the chapter on the parking aid is to be read carefully and the safety notes are to be observed.

Automatic brake assist
Read and observe
and on page 226 first.
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
parking process stops due to the speed of 7 km / hr being exceeded!Malfunctions

If, for some unknown reason, the system is not available, an appropriate mes-
sage appears in the display of the instrument cluster.

Operation description

The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal. The state where the CCS maintains the speed is
referred to hereinafter as the control.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 212, in section Introduction .■
After pressing the clutch pedal, no interrupted control occurs! For exam-
ple, if a different gear is engaged and the clutch pedal is released, control is
continued.

If no speed is set the current speed is adopted.
After the start of the regulation, the CCS regulates the vehicle to the current
speed and the warning light illuminates in the instrument cluster.
230Driving
The automatic control interruption occurs if any of the following conditions
are met. ▶ The brake pedal is operated.
▶ When one of the brake assist systems (e.g. ESC) intervenes.
▶ By pressing the button D
» Fig. 289 .
▶ Through an airbag deployment.
WARNING■ Always deactivate the cruise control system after use to prevent the sys-
tem being switched on unintentionally.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.
Note
■ During control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set
speed.■

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 212.
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 212, 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 in “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 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, the
warning light lights up in the instrument cluster and the display shows a
message to engage the brake pedal.
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 stopping and starting
Read and observe
on page 233 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.
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 regulated.
34234Driving
If the preceding vehicle starts moving again after a long break, then to contin-
ue the regulation press the accelerator pedal or lever to set the lever in
