tion about the condition of the vehicle, events
and faults. This technical information generally
records the state of a component, a module, a system or the environment:
▷Operating mode of system components, fill
levels for instance.▷Status messages for the vehicle and from
its individual components, e.g., wheel rota‐
tion speed/vehicle speed, deceleration,
transverse acceleration.▷Malfunctions and faults in important sys‐
tem components, e.g., lights and brakes.▷Responses by the vehicle to special situa‐
tions such as airbag deployment or engag‐
ing the stability control system.▷Ambient conditions, such as temperature.
This data is purely technical in nature and is
used to detect and correct faults and to opti‐
mize vehicle functions. Motion profiles over
routes traveled cannot be created from this
data. When service offerings are used, e.g., re‐
pair services, service processes, warranty
claims, quality assurance, this technical infor‐
mation can be read out from the event and
fault memories by the service personnel, in‐

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.◀

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.
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
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.

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.
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.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press the rocker switch up to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point
of resistance: the speed increases while
the rocker switch is pressed.▷Press the rocker switch down to the point
of resistance: the speed decreases gradu‐
ally.▷Press the rocker switch down past the
point of resistance: when driving forward,
the speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.
Activating HDC
Press button; the LED above the button
lights up.

Driving comfortVehicle features and options
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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Active Cruise Control with Stop & Go function, 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.
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 reduces the speed, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits. Your own vehicle will
brake automatically and then accelerate again.
If the vehicle ahead of you drives away again
after a prolonged period, briefly press the ac‐
celerator pedal or press the appropriate button
to reactivate the system. The vehicle will auto‐
matically accelerate.As soon as the road is clear, the vehicle accel‐
erates to the desired speed.
The speed is also maintained downhill, but
may not be maintained uphill if engine power is
insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Personal responsibility
Even an active system holds the driver
responsible 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, e. g. if there is rain, snowfall,
slush, fog or glare, this may result in poorer
recognition of vehicles as well as short-term
interruptions for vehicles that are already de‐
tected. Drive attentively, and react to the cur‐
rent 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 130ControlsDriving comfort130

The indicator lights in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press button.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
is deleted.
Interrupting When active, press the button.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:
▷When the brakes are applied.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed
Press button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
