tempts to steal a wheel or when towing the
car.▷Interruptions in battery voltage.
The alarm system briefly indicates tampering:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.▷By flashing the high beams.
Arming and disarming the alarm
system
General information

When the lights are switched on, the high beams
are switched on and off automatically.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities.

System limits Personal responsibility
The high-beam assistant cannot serve as
a substitute for the driver's personal judgment
of when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.▷In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Camera
The camera is located near the base of the mir‐
ror.

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.◀
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

PDC Park Distance Control
The concept
In addition to the PDC Park Distance Control, the
backup camera, refer to page 116, can be
switched on.
PDC supports you when parking. Objects that
you are approaching slowly in front of or behind
your vehicle are indicated by:
▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and the two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
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.Seite 114ControlsDriving comfort114
