standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Dynamic Damping Control
The concept This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort fitting road surface and driving style.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 130.
SPORT
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
SPORT+ Consistently sporty control of the shock ab‐
sorbers for greater driving agility when driving
with limited driving stabilization.
COMFORT/ECO PRO
Balanced control of the vehicle.
Variable sport steering The variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.Seite 129Driving stability control systemsControls129
Online Edition for Part no. 01 40 2 964 144 - VI/15
ServotronicThe concept
The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel and/or comfortable steering is con‐
veyed.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
The Driving Dynamics Control and the DSC
OFF buttons can each be used to activate a
program.

DSC OFF
When DSC OFF, refer to page 127, is active,
driving stability is limited during acceleration
and when driving in curves.

maximum traction on loose road surfaces. DTC
Dynamic Traction Control, refer to page 127, is
activated. Driving stability is limited during ac‐
celeration and when driving in curves.
SPORT+
Sporty driving with optimized suspension and
adapted engine control with limited driving sta‐
bilization.
Dynamic Traction Control is switched on.
The driver handles several of the stabilization
tasks.

Radar sensor
A radar sensor is located in the front bumper for detecting vehicles on the road ahead of the
vehicle.
Always keep radar sensor clean and unob‐
structed.
Camera
The camera is installed near the interior rear‐
view mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.
A dirty or covered area in front of the interior
mirror may hinder the detection of vehicles.
If necessary, clean the area in front of the inte‐
rior mirror, e.g., carefully remove salt residue in
the winter.

InterruptingWhen active, press the button on the
steering wheel.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:▷When the brakes are applied.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.▷After a longer stationary period when the
vehicle has been braked to a stop by the
system.
Maintaining, storing, and changing the
speed
Information WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively interfere in the respective situations.◀
WARNING
Risk of accident due to too high speed
differences to other vehicles, e.g. in the follow‐
ing situations:
▷When fast approaching a slowly moving
vehicle.▷Suddenly swerving vehicle onto the own
lane.▷When fast approaching standing vehicles.
There is risk of injuries or danger to life. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
Maintaining/storing the speed Press button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed in the speedometer and
briefly in the instrument cluster, refer to
page 136.
DSC Dynamic Stability Control will be
switched on if needed.
Changing the speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed when the
road is clear.
▷Each time the rocker switch is pressed to
the point of resistance, the desired speedSeite 135Driving comfortControls135

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀

Pathway lines
Pathway lines can be superimposed on the im‐
age of the rearview camera.
Pathway lines help you to estimate the space
required when parking and maneuvering on
level roads.
Pathway lines depend on the current steering
angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can only be superimposed
on the rearview camera image together with
pathway lines.
Turning circle lines show the course of the
smallest possible turning radius on a level
road.
Only one turning radius line is displayed after
the steering wheel is turned past a certain an‐
gle.
Obstacle marking
Obstacles behind the vehicle are detected by
the PDC sensors and, when respectively
equipped, detected by the rearview camera.
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins of the obstacle mark‐
ings match the markings of the PDC.
