Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the two sys‐
tems:▷Front-end collision warning with City Brak‐
ing function, refer to page 118.▷Front-end collision warning with braking
function, refer to page 120
Front-end collision warning
with City Braking function
The concept The ystem can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally the collision warning is delayed
avoiding false alarm.
General information The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range
It responds to objects if they are detected by
the system.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀
Adapting your speed and driving style
The displays and warnings of the system
do not relieve the driver of the responsibility to
adapt his or her driving speed and style to the
traffic conditions.◀
Be alert
Due to system limitations, warnings may
be not issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the risk
of an accident.◀
Tow-starting and towing
For tow-starting or towing, switch off the
Intelligent Safety systems; otherwise malfunc‐
tions of the individual braking systems might
lead to accidents.◀

Online Edition for Part no. 01 40 2 954 312 - II/15
Acute warnings can also be triggered without
previous prewarning.
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 boos‐
ter is sufficiently quick and hard stepping 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
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively 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 warning might not be issued or be is‐
sued 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 driving stability control systems are
limited or deactivated, e.g., DSC OFF.▷If, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is 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,
e.g. the warning time, the more warnings are
displayed. However, there may also be an ex‐
cess of false warnings.
Front-end collision warning
with braking function
The concept The ystem can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention may be
executed with maximum braking force and for
a brief period only as necessary.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the front-end collision
Seite 120ControlsSafety120

warning is controlled via the cruise control ra‐
dar sensor in conjunction with a camera.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally the collision warning is delayed
avoiding false alarm.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sit‐
uation.
Detection range
It responds to objects if they are detected by
the system.

Driving stability control systemsVehicle features and optionsThis 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
systems. The respectively applicable country
provisions must be observed when using the
respective 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.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out 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 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 to
roll back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note 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, not
even with DSC.
