The alarm system responds in situations such as
attempts to steal a wheel or when the car is
towed.
Interior motion sensor The windows and glass sunroof must be closed
for the system to function properly.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be switched off together, such as in the fol‐
lowing situations:▷In automatic car washes.▷In duplex garages.▷During transport on trains carrying vehicles,
at sea or on a trailer.▷With animals in the vehicle.
Switching off the tilt alarm sensor and
interior motion sensor
Press the remote control button again
within 10 seconds as soon as the vehi‐
cle is locked.
The indicator lamp lights up for approx. 2 sec‐
onds and then continues to flash.
The tilt alarm sensor and interior motion sensor
are turned off, until the vehicle is locked again.
Switching off the alarm
▷Unlock vehicle with the remote control or
switch on the ignition, if needed through
emergency detection of remote control, re‐
fer to page 23.▷With Comfort Access: If you are carrying the
remote control on your person, grasp the
driver side or front passenger side door
handle completely.
Unlock vehicle with the remote control or
switch on the ignition, if needed through emer‐
gency detection of remote control, refer to
page 23.

Note Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., cannot
operate the power windows and injure them‐
selves. ◀

Opening
▷ Press the button to the resistance
point.
The window opens while the switch is held.▷ Press the switch beyond the resist‐
ance point.
The window opens automatically. Pressing
again stops the motion.

Speed limit detection
The concept
Speed limit detection
Speed limit detection uses a symbol in the
shape of a traffic sign to display the currently
detected speed limit. The camera at the base of
the interior rearview mirror detects traffic signs
at the edge of the road as well as variable over‐
head sign posts. Traffic signs with extra symbols
for wet road conditions, etc. are also detected
and compared with the vehicle's onboard data,
such as for the rain sensor, and will be dis‐
played depending on the situation.
Without a navigation system, the system is sub‐
ject to limitations imposed by technology.
Speed limits with extra text characters are al‐
ways displayed.
Hints
Speed limits when towing a trailer are not
shown.
Personal judgment
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation.
The system assists the driver and does not re‐
place the human eye. ◀
At a glance
Camera
The camera is found near the interior rearview
mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.

Signal tones
When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the ve‐
hicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, 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 to the
rear of the vehicle, an alternating continuous
signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume settings
of the radio.
Settings are stored for the profile currently in
use.
System limits
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, damaged
or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.▷For objects with porous surfaces.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
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 with
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Seite 107Driving comfortCONTROLS107

Functional limitationsThe system may not be fully functional in the
following situations:▷On bumpy road surfaces such as gravel
roads.▷On slippery ground.▷With accumulations of leaves/snow in the
parking space.▷With a mounted emergency wheel.
