Head-up Display
The concept
This system projects important information
into the driver's field of vision, e.g., the speed.
The driver can get information without averting
his or her eyes from the road.
Display visibility The visibility of the displays in the Head-up
Display is influenced by the following factors:
▷Certain sitting positions.▷Objects on the cover of the Head-up Dis‐
play.▷Sunglasses with certain polarization filters.▷Wet roads.▷Unfavorable light conditions.
If the image is distorted, check the basic set‐
tings.

NotePersonal 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 an
accident is still possible despite all warnings.◀

Collision warning
Depending on how the equipment is equipped,
the collision warning system consists of one of
the following functions:
▷Collision warning with City Braking func‐
tion, refer to page 113.▷Collision warning with braking function, re‐
fer to page 116
Collision warning with City
Braking function
The concept The system can help to prevent accidents. If
an accident cannot be prevented, the system
helps to reduce the collision speed.
The system issues a warning if there is immi‐
nent danger of a collision and if so brakes inde‐
pendently.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.

▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.▷Pedestrians.
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, for example, DSC
OFF.▷If the camera in the mirror or the radar sen‐
sor is dirty or obscured.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant dimming because of
oncoming light, for example, from the sun
low in the sky.
Prewarning sensitivity
Depending on the set prewarning time, this
may result in increased false warnings.
Collision warning withbraking function
The concept
The system issues a warning if there is immi‐
nent danger of a collision and also includes a
braking function.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor in
conjunction with a camera.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
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. The time
of these warnings may vary depending on the
current driving situation.
Detection range
It responds to stationary or moving objects
that are within the detection range of the radar
system.

Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, 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 system
automatically produces the maximum braking
force boost. This then reduces braking dis‐ tance 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.
When equipped with Driving Assistant Plus or
with Active Cruise Control with Stop & Go
function, ACC is supported by the braking in‐
tervention if there is a possible risk of collision.
To do this, the braking force is automatically increased if the braking pressure is insufficient
when the brakes are applied.Drive-off assistant
This system supports driving away on gradi‐
ents. 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.◀
Automatic Differential Brake
The system controls the driving force by auto‐
matic braking intervention on individual
wheels. The function corresponds to a differ‐
ential lock: the system detects if a wheel be‐
gins to spin, because of loose road surface, for
example, and automatically brakes it.
The driving force is diverted to the wheel with
better traction.
As a result, the engine force is transferred
more efficiently to the wheels during accelera‐
tions.

Online Edition for Part no. 01 40 2 926 740 - X/13
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.
Use HDC in low gears or in transmission posi‐
tion D or R only.
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 up the rocker switch 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 down the rocker switch to the point
of resistance: the speed decreases gradu‐
ally.▷Press down the rocker switch 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 the button; the LED above the but‐
ton lights up.
Deactivating HDC Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.
Display in the instrument cluster The selected speed is displayed
in the speedometer.
▷Green: the system is actively
braking the vehicle.▷Orange: the system is on
standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Active Steering
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At lower speeds, for example during turning or
maneuvering, the steering angle is increased,
that is to say the steering becomes more di‐
rect.
