PrewarningThis warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake booster
is sufficiently quick and sufficiently hard step‐
ping on the brake pedal. The system can assist
with some braking intervention if there is risk of
a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.System limits
Detection range The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐ tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
front windshield are dirty or covered.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
the more warnings are displayed. However,
there may also be an excess of false warnings.

Pedestrian warning with
city braking function
The concept
The system can help prevent accidents with pe‐
destrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
A camera at the base of the rearview mirror
controls the system.
General information
With sufficient brightness, the system warns
about possible collision danger with pedes‐
trians starting at approx. 6 mph/10 km/h to ap‐
prox. 35 mph/60 km/h and assists with braking
before a collision.
Under those circumstances it reacts to people
who are within the detection range of the sys‐
tem.
Detection range
The detection area in front of the vehicle is div‐
ided into two areas
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.
Information WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to system
limits, warnings or reactions of the system may
not be output or they may be output too late or
incorrectly. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g. approach control warning with light brak‐
ing function. There is risk of an accident. Switch
all Intelligent Safety systems off prior to tow-
starting/towing. ◀

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.
Anti-lock Braking 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.
Information Adapt your driving style to the situation, for an
appropriate driving style is always the responsi‐
bility 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.
WARNING
When driving with roof load, e.g. with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is risk of
accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC when
driving with roof load. ◀

Deactivating DSC: DSC OFFWhen 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.
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.

Performance Control
Performance Control enhances the agility of the
vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually.

tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not

the selected options or country versions. This
also applies to safety-related functions and sys‐

Camera-based cruise con‐
trol
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.
Active cruise control is paused below approx.
20 mph/30 km/h.
The system does not brake to a stop.
Depending on the driving program, refer to
page 99, set, the characteristics of the cruise
control in particular areas can change.
Information WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. Based on the limits of the system,
it cannot independently react to all traffic situa‐
tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀
