Warning with braking function
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a signal
sounds.
Intervene immediately by braking or
make an evasive maneuver.
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.

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
Dynamic Stability Control detect for example
the following unstable driving conditions:▷Fishtailing, which can lead to oversteering.▷Loss of traction of the front wheel, which
can lead to understeering.
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to the
individual wheels.
Information The system does not relieve the driver from his
responsibility to adjust his driving style accord‐
ing to the situation.
Therefore, adjust the driving style according to
the situation and do not reduce the additional
safety margin by driving in a risky manner.
WARNING
When driving with roof load, for example
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. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.

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‐

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 118, 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. ◀

System limits
Information WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed. ◀
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 capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
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. ◀
Deceleration The system also does not decelerate in the fol‐
lowing situations:
▷In case of pedestrians, cyclists or similar
slow road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.▷Unlit vehicles or vehicles with nonworking
lighting at night.Seite 124CONTROLSDriving comfort124

Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
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, for ex‐
ample, when rapidly approaching a truck.
When a vehicle driving ahead of you is reliably
detected, the system requests that the driver
intervene by braking and carrying out evasive
maneuvers, if needed.
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. ◀
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.
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 traffic
situation. If necessary, intervene actively, for
example by braking, steering or evading.
