not be available in the following situations:▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera view field or the front wind‐
shield 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.▷When it is dark outside.

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehi‐
cle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle remains steerable 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 systemautomatically produces the maximum braking
force boost. This then reduces braking distance
to a minimum during full braking. This system
utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to 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 situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner. ◀
Indicator/warning lamps The indicator lamp flashes: DSC controls
the drive forces and brake 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
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.Seite 86ControlsDriving stability control systems86

DSC OFF and the DSC OFF indicator lamp go
out.
Indicator/warning lamps 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:▷Failure of Dynamic Damping Control.▷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 in which
forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate 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 rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground. TRACTION is activated. Driving stability is lim‐
ited during acceleration and when driving in
bends.
Activating DTC Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press the button again.
TRACTION and the DSC OFF indicator
lamp go out.
Performance Control
Performance Control enhances the agility of
your vehicle.
To enhance performance during sporty driving,
the front wheel on the inside of the curve is
braked while the resulting braking effect is
largely compensated by engine intervention.
Dynamic Damping Con‐
trol
The concept
This system reduces undesirable vehicle motion
when using a dynamic driving style or traveling
on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.Seite 87Driving stability control systemsControls87

Programs
The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 88.
MID/GREEN Balanced control of the vehicle.
SPORT Consistently sporty control of the shock absorb‐
ers for greater driving agility.
Driving Dynamics Con‐
trol
The concept
The Driving Dynamics Control can be used to
adjust the certain characteristics of the vehicle.
Three different programs can be selected for
this purpose. By turning the Driving Dynamics
Control, a particular program can be activated.
Operating the programsDriving Dynamics ControlProgramMID

MID For a balanced tuning with maximum driving
stabilization.
With each starting operation, MID is activated
using the Start/Stop button.
GREEN GREEN, refer to page 131, provides consistent
tuning to minimize fuel consumption for maxi‐
mum range with maximum driving stabiliza‐
tion.

Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is being used, the vehicle may roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back. ◀Seite 89Driving stability control systemsControls89

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehi‐
cle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Camera-based cruise con‐
trol, ACC
The concept
This system can be used to select a desired
speed that the vehicle will maintain automati‐
cally 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, it accelerates to the
desired speed.
The speed is also maintained on downhill gradi‐
ents, but may not be maintained on uphill
slopes if engine power is insufficient.
General information
Depending on the set drive mode, refer to
page 88, the characteristics of the cruise con‐
trol can change in certain areas.Hints
Personal responsibility
Even an active system does not release
the driver from personal responsibility for the
driving process, especially for lane tracking, adaptation of speed, distance and driving style
to the traffic conditions.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Monitor the driving process, the surrounding
area and what is occurring in traffic continu‐
ously and attentively and actively intervene as
required, e.g., by braking, steering or making
an evasive maneuver. ◀
Unfavorable weather conditions
Unfavorable weather conditions, e.g.,
rain, snowfall or slush, may result in worsened
detection of vehicles as well as short-term in‐
terruptions with already detected vehicles.
Drive attentively, and react to the current traffic
events. Intervene actively when necessary, e.g.,
by braking, steering or making an evasive ma‐
neuver, otherwise, there is danger of an acci‐
dent. ◀
