Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Antilock Brake System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the power wheels
when driving off and accelerating.
DSC also recognizes unstable vehicle conditions
such as fishtailing or nose-diving. Within the
physical limits DSC helps to keep the vehicle on
a steady course by reducing engine speed and
by applying brakes to the individual wheels.
Adjust your driving style to the situationAn appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
curves.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.Seite 94CONTROLSDriving stability control systems94

The DSC system is switched off.
Activating DSC Press button.
DSC OFF and the DSC OFF indicator
lamp go out.
Indicator/warning lights
When DSC is deactivated, DSC OFF is displayed
in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
Automatic activation When DSC is deactivated, automatic activation
occurs in the following situations:▷The vehicle has a flat tire.▷When activating cruise control in TRACTION
or DSC OFF mode.
DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating DTC Press button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press button again.
TRACTION and the DSC OFF indicator
lamp go out.
Performance Control
Performance Control enhances the agility of the
vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually.
Dynamic Damping Con‐
trol
The concept
The tuning of the suspension can be changed
with the system.
Programs
The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 96.

Driving comfortVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Camera-based cruise con‐
trol, ACC
The concept
Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
A camera on the interior rear view mirror is
used to detect vehicles driving ahead.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
As soon as the road is clear, the vehicle acceler‐
ates to the desired speed.
The speed is also maintained downhill, but may
not be maintained uphill if engine power is in‐
sufficient.General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the set drive mode, refer to
page 96, the features of the cruise control can
change in certain areas.
Hints Personal responsibility
Even an active system holds the driver re‐
sponsible for his or her driving, particularly for
staying in your lane, adjusting your speed,
keeping your distance and for your driving style
all in relation to traffic.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed, e.g. through braking,
steering or make evasive maneuvers - risk of
accident. ◀
Unfavorable weather conditions
In the event of unfavorable weather and
light conditions, for instance if there is rain,
snowfall, slush, fog or glare, this may result in
poorer recognition of traffic situations as well
as short-term interruptions for vehicles that are
already detected. Drive attentively, and react to
the current traffic situation. Intervene actively
when necessary, e.g., by braking, steering or
making an evasive maneuver, otherwise, there
is the risk of an accident. ◀Seite 98CONTROLSDriving comfort98

pedal.
The vehicle symbol flashes red and an
acoustic signal sounds:
You are requested to intervene by brak‐
ing or make an evasive maneuver.
The system has been interrupted or dis‐
tance control is temporarily suppressed
because the accelerator pedal is being
pressed; a vehicle was not detected.

System limits
Speed range The system is best used on well-constructed
roads. The system is functional at speeds be‐
ginning at approx. 20 mph/30 km/h.
The max. speed that can be set is
85 mph/140 km/h.
Comply with the legal speed limit and safety
distance in every situation when using the sys‐
tem.Detection range
The detection lidacity of the system and the au‐
tomatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because the camera detection system's
potential is limited, you should be alert at all
times so that you can intervene actively, if
needed; otherwise, there is the risk of an acci‐
dent. ◀
Deceleration
The system does not decelerate for:
▷Pedestrians, cyclists or similar slow road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.▷Unlit vehicles or vehicles with defective
lighting at night.Seite 102CONTROLSDriving comfort102

Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed. You must react yourself; other‐
wise, there is the risk of an accident. ◀
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 decelerates
you may compensate it by briefly accelerating.
After releasing the gas pedal the system is reac‐
tivated and controls speed independently.
Malfunction
A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:
▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera viewing field or the front
windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.Seite 103Driving comfortCONTROLS103
