Central locking system
The concept
The central locking system functions when the
driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
>Liftgate
>Fuel filler flap
Operating from outside
>Using the remote control
>Using the door lock
>With Comfort Access
* using the door han-
dles
The interior lamps and the courtesy lamps
* are
also switched on and off with the remote con-
trol. The alarm system
is armed/disarmed at the
same time.
You can find more detailed information on the
alarm system
on page34.
Operating from inside
Using the button for central locking, refer to
page30. The fuel filler flap is not locked.
In an accident of sufficient severity, the central
locking system automatically unlocks the vehi-
cle. In addition, the hazard warning flashers and
interior lamps come on.

Volume of warning tones
You can raise or lower the volume of the warn-
ing signals, e.g. the safety belt reminder, in rela-
tion to the entertainment sound output. The
warning tones have a specified minimum and
maximum volume that cannot be dropped
below or exceeded.

PDC Park Distance Control*
The concept
In addition to the PDC Park Distance Control,
the rear view camera
*, refer to page93, can
also be switched on.
PDC assists you during parking. A slow
approach to an object in front of or behind your
vehicle is announced by:
>Signal tones
>Optical displays
Measurement
Ultrasonic sensors in the bumpers carry out the
measurement.
Their range is approx. 7 ft/2 m.
The acoustic warning begins:
>At approx. 24 in/60 cm for the front
* sen-
sors and the two rear corner sensors.
>At approx. 5 ft/1.50 m for the middle sen-
sors in the rear.
System limitations
PDC cannot replace the personal assess-
ment of the traffic situation. Also make a
direct visual check of the traffic situation around
the vehicle. Otherwise, there could be a risk of
accident, for example due to other road users or
objects outside the detection range of PDC.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Avoid approaching an object too quickly.
Avoid starting off quickly while PDC is not
yet activated.
Otherwise, physical circumstances could cause
the system to issue a warning late.<
Limitations of ultrasonic measurement
The detection of objects can come up against
the limitations of physical ultrasonic measure-
ment, for example:
>When using tow bars and towing hitches
>In the presence of thin or wedge-shaped
objects
>In the presence of low objects
>In the presence of objects with corners and
sharp edges
Low objects that have already been displayed,
e.g. curbs, can disappear again from the detec-
tion area of the sensors before or after a contin-
uous tone sounds.
Higher, protruding objects, e.g. ledges, cannot
be detected.
False warnings
Under the following conditions, PDC may dis-
play a warning even though no obstacle is
present in the detection range:
>In heavy rain
>When the sensors are heavily soiled or iced-
over
>When the sensors are covered with snow
>On rough road surfaces
>In large, rectangular buildings with smooth
walls, e.g. underground garages
>In the presence of heavy exhaust
>Due to the presence of other ultrasonic
sources such as street sweepers, steam
cleaners, or neon lamps.
Automatic activation
With the engine running or the ignition switched
on, shift the selector lever into position R.
Automatic deactivation
The system switches off and the LED goes out:

Switching on/off manually
Press the button.
>On: LED lights up
>Off: LED goes out
Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc.
The shorter the distance to the object
becomes, the shorter the intervals become.
If the distance to the nearest object falls to
below roughly 1 ft/30 cm, then a continuous
tone sounds.
If objects are present both in front of and behind
the vehicle, then an alternating, continuous
tone sounds.
An intermittent tone is interrupted after approx.
3seconds:
>When the vehicle remains stationary in front
of an object that has only been detected by
one of the corner sensors
>When driving parallel to a wall
The signal tone is switched off:
>When the vehicle is more than approx.
4.0 in/10 cm away from an object
>When the selector lever is in the P position
Volume
You can adjust the volume of the signal tone,
refer to page87.
The setting is stored for the remote control cur-
rently in use.
Optical warning
The approach to an object can be shown on the
Control Display. Objects that are farther away
are displayed on the Control Display before a
signal tone sounds.
The display appears as soon as PDC is acti-
vated.
If the last image selected was the rear view
camera, this is displayed again. To switch to
PDC:
1.Select the "Switch off rear view cam-
era" on the Control Display.
2.Press the controller.
The setting is stored for the remote control cur-
rently in use.

Malfunction
A Check Control message appears in the
instrument panel, refer to page82.
The areas in front of and behind the vehicle
appear in shaded form on the Control Display.
PDC is malfunctioning. Have the system
checked.
In order to assure full functionality:
>Keep sensors clean and free of ice.
>Do not spray the sensors with high-pres-
sure cleaners for long periods and keep the
spray nozzle at least 12 in/30 cm away from
them.
Surround View*
The concept
Surround View encompasses the following sys-
tems:
>Top View
*, refer to page90
>Side View
*, refer to page92
>Rear view camera
*, refer to page93
It provides assistance when parking and
maneuvering and at blind driveways and inter-
sections.
Top View*
The concept
Top View assists you when parking and maneu-
vering. To accomplish this, the door region and
road surface region are shown on the Control
Display.
Detection
Detection is carried out by two cameras inte-
grated into the exterior mirror and the rear view
camera.
The range is:
>Approx. 7 ft/2 m to the side
>Approx. 7 ft/2 m to the rear
Obstacles up to the height of the exterior mir-
rors are thus detected in a timely fashion.
System limitations
In the following situations, the function of Top
View is limited:
>When a door is open
>When the liftgate is open
>When the exterior mirrors are folded in
>Under poor lighting conditions
The arrows next to the vehicle are displayed in a
shaded form on the Control Display and a sym-
bol appears at the corresponding location on
the vehicle.
Also make a direct visual check of the
traffic situation around the vehicle. Other-
wise, there could be a risk of accident, for exam-
ple due to other road users or objects outside
the image range of the camera.<
Automatic activation
With the engine running or the ignition switched
on, shift the selector lever into position R.
The images from Top View and PDC are dis-
played when the system has been switched on
using iDrive.
Automatic deactivation
The system switches off and the LED goes out:
>After approx. 165 ft/50 m when driving for-
ward
>At speeds over approx. 25 mph/35 km/h
