In the process, vehicles in a similar direction of
movement are observed if they are located
within the detection range of the system.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid misleading warnings.
Warning stages

This warning is issued, for example, when there
is the impending danger of a collision or the dis‐

Acute warning
Warning of the imminent danger of a collision
when the vehicle approaches another vehicle at
a relatively high differential speed.

Prewarning
This warning is issued, for example, when there

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 will not bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control 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.

Lane departure warning
The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane mark‐
ings is about to leave the lane. Depending on the
country-specific version of the vehicle, the
speed is between 35 mph/55 km/h and
45 mph/70 km/h. When switching on the system
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in the
event of warnings. The time of the warning may
vary depending on the current driving situation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Notes Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the course
of the road and the traffic situation.
In the event of a warning, do not jerk the steering
wheel, as you may lose control of the vehicle.◀

a warning is not issued.
End of warning
The warning ends:▷Automatically after approx. 3 seconds.▷When returning to your own lane.▷When braking hard.▷When using the turn signal.
System limits
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merging,
diverging, or multiple lane markings such as
in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by ob‐
jects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield behind the interior

Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper mon‐
itor the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehicles
in the blind spot, arrow 1, or approaching from
behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights up
dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the situa‐
tions described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Notes Personal responsibility
The system does not serve as a substitute
for the driver's personal judgment of the traffic
situation.
Be aware of the traffic situation and the vehicle's
surroundings at all times, otherwise an accident
is still possible despite all warnings.◀

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. 10 in/25 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
The volume of the PDC signal can be adjusted,
refer to user's manual for Navigation, Entertain‐
ment and Communication.
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.
A display appears as soon as Park Distance
Control (PDC) is activated.

System limits
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, e.g.:
▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded
area on the Control Display.
PDC has failed. Have the system checked.
To ensure full operability:▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.
Surround View
The concept
Surround View includes the following systems:
▷Backup camera, refer to page 129.▷Side View, refer to page 134.▷Top View, refer to page 132.
It assists the driver when parking, maneuvering
and on blind driveways and intersections.
Backup camera
The concept
The backup camera provides assistance in park‐
ing and maneuvering backwards. The area be‐
hind the vehicle is shown on the Control Display.
Notes Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside the picture area of the backup camera. ◀
