Collision warning with
braking function*
The concept
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with an object, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This
warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill. The braking intervention is executed only if DSC
Dynamic Stability Control, refer to page
99, is
switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When
towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.
Switching the warning function on/off Press the button
▷ On: the LED lights up.
▷ Off: the LED goes out.
The state is stored for the remote control cur‐
rently in use.
Configuring the prewarning
After the warning function is switched on, the
following can be set via the iDrive:
▷ The prewarning can be switched on/off.
▷ The time of the prewarning can be set.
These settings have no effect on the time of the
warning from the Active Cruise Control* that
prompts the driver to intervene or brake. Seite 112

creases or decreases by approx. 1 mph/
1 km/h.
▷ Each time the rocker switch is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h.
▷ Pressing the rocker switch to the resistance
point and holding it accelerates or deceler‐
ates the vehicle without requiring pressure
on
the accelerator. After the rocker switch is
released, the vehicle maintains its final
speed. Pressing the switch beyond the re‐
sistance point causes the vehicle to accel‐
erate more rapidly. Seite 114

Signal tones
When approaching an object, an intermittent
tone
is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:
▷ If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.
▷ If moving parallel to a wall.
The signal tone is switched off:
▷ When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.
▷ When transmission position P is engaged.
Volume
You can set the volume of the PDC signal tone,
refer to page 173.
The
setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.

Night Vision with pedestrian
detection*
The concept
Night
Vision with pedestrian detection is a night
vision system.
An infrared camera records the area in front of
the vehicle and displays the image on the Con‐
trol Display.
The picture is a heat image. The system has an
integrated pedestrian detection function that
detects pedestrians and cyclists. Warm objects
that are similar in shape to human beings are
detected by the system.
Personal responsibility
Night Vision cannot replace the driver's
personal judgment of the visibility conditions
and the traffic situation. The view ahead and the
actual visibility conditions must always be the
basis on which the vehicle speed is adjusted;
otherwise, there is a risk to road safety.◀ Seite 122

Warning area in front of the vehicle
The warning area in front of the vehicle is divided
into two areas.
▷
Central area 1 directly in front of the vehicle.
▷ Expanded area 2 to the right and left.
The entire area moves along with the vehicle in
the direction of the steering angle and changes
with
the vehicle speed. As the vehicle speed in‐
creases, the area becomes longer and wider, for
example.
Symbols
This symbol is displayed when a person
is detected in the central area, arrow 1,
immediately in front of the vehicle.
This symbol is displayed when a person
detected in the extended area, arrow 2,
is moving from the right or left to the
central area.
Display in the Head-up Display*
The warning is simultaneously dis‐
played in the Head-up Display and in the
Control Display. The displayed symbol
can vary with the people detected. For people
located in the central area, the distance to the
person is indicated by the size of the symbol.
System limits
Basic limits
System operation is limited in situations such as
the following:
▷ On steep hills, in steep depressions or in
tight curves. ▷
When the camera is dirty or the protective
glass is damaged.
▷ In heavy fog, rain or snowfall.
▷ At very high external temperatures.
Limits of pedestrian detection
Animals are not detected by the pedestrian de‐
tection
function, even if they are clearly visible in
the image.
Limited pedestrian detection:
▷ When people are fully or partially covered,
especially when their heads are covered.
▷ When people are not in an upright position,
e.g., when lying down.
▷ Cyclists on unconventional bicycles (e.g.,
recumbent bicycles).
▷ After physical damage to the system, e.g.,
after an accident.
