Do not move hardtop
When the rollover protection system is
extended, do not move the hardtop. Other‐
wise, damages or injuries may result.◀
If the rollover protection system was not
placed under any stress after an automatic
triggering, it can be pushed back by hand, e.g.
to close the hardtop. The protective function of
the system is then restored.1.Pull the release lever in the safety frame up
and hold it, arrow 1.2.Push the safety frame down, arrow 2.3.Release the release lever only if the safety
frame was pushed back almost completely.4.Push the safety frame down until it notice‐
ably engages. To do this, the safety frame
must be pressed far into its holder; high
levels of force are required.
Do not bend via the safety frame
Should the safety frame not have
snapped in place when it is released, then
it moves back up with jerking movements.
When it is released, do not bend via the
safety frame; otherwise, there is a risk of
injury with a safety frame that is not en‐
gaged.◀
Slowly reduce pressure on the safety
frame in order to test whether it is latched.5.Proceed likewise with the second safety
frame.Malfunction
A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM The concept
The system monitors tire inflation pressure in
the four mounted tires. The system warns you
if there is a significant loss of pressure in one
or more tires. For this purpose, sensors in the
tire valves measure the tire inflation pressure
and tire temperature.
Hints Tire damage due to external factors
Sudden tire damage caused by external
circumstances cannot be recognized in ad‐
vance.◀
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 172.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display
The current status of the Tire Pressure Moni‐
tor TPM can be displayed on the Control Dis‐
play, e.g., whether or not the TPM is active.

Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀

PDC Park Distance Control
The concept PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availa‐
ble - then the object is reported through:
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given:▷By the front sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
To ensure full functionality:
▷Do not cover sensors, e.g., with stickers,
bicycle racks.▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Avoid driving fast with PDC

Display
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
vehicle, 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.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume set‐
tings of the radio.
Settings are stored for the profile currently 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 already displayed on the
Control Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors green, yellow and red.

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, dam‐
aged or out of position.Seite 125Driving comfortControls125

▷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 ga‐
rages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continu‐
ous tone alternating between the front and
rear speakers. As soon as the malfunction
due to other ultrasound sources is no lon‐ger present, the system is again fully func‐
tional.

on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 124.

Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
