Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. A Check Control message
encompasses indicator and warning lamps in
the instrument cluster and may include an
acoustic signal and text messages on the Con-
trol Display.
Indicator and warning lamps
Indicator and warning lamps can light up in a
variety of combinations and colors. indicates that Check Control messages have
been stored. You can view the Check Control
messages whenever it is convenient for you.
Explanatory text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
For most Check Control messages, you can
view more information later, e.g., regarding the
cause of a malfunction and how to respond;
refer to the information provided below.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
To exit the displayed information:
Move the controller to the left.

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
in front of
* or behind your vehicle. To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an objec t a t h i g h s p e e d ; o t h -
erwise, physical circumstances may lead to the
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph or 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds>If you remain in front of an object that has
been detected by only one of the corner
sensors
>If you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display.Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 12 in/30 cm.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g., curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g.,
ledges, cannot be detected. Therefore, always
drive cautiously; otherwise, there is a risk of
personal injury or property damage.

Dynamic Driving Control
The concept
Dynamic Driving Control can be used to adjust
the driving dynamics of the vehicle.
Several programs are available for this purpose;
they can be activated using the two Dynamic
Driving Control buttons.
The following characteristics are adapted,
depending on which program was selected:
>Engine response.
>Shift times of the automatic transmission
*.
>Power steering support
*.
>Changes in the suspension characteristics
through damping control
*.
>Vehicle stabilization through DSC Dynamic
Stability Control.
Operating the programs
1You can activate or deactivate the following
programs using this button:
>DSC OFF
>TRACTION
2You can activate or deactivate the following
programs using this rocker switch:
>SPORT+
>SPORT
>NORMAL
DSC OFF
Driving stability is limited during acceleration
and when driving in bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC OFF
Press and hold the button, but not
longer than approx. 10 seconds, until
the indicator lamp for the DSC lights up in the
instrument cluster and DSC OFF is displayed in
the instrument cluster.
The DSC system is switched off.
Deactivating DSC OFF
Press the button.
DSC OFF and the DSC indicator lamp
go out.
For better control
When DSC is switched off, DSC OFF is dis-
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
TRACTION
Maximum traction on loose road surfaces. DTC
Dynamic Traction Control is switched on. Driv-
ing stability is limited during acceleration and
when driving in bends.

assistant will not hold the car in place after
approx. 2 seconds, the car would otherwise
start to roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period
of time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<1."Vehicle Info"

4.Start the engine - do not drive away.
5.Start the initialization using "Reset".
6.Start to drive.
The initialization is completed during the trip.
The initialization is completed during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with run-flat
tires, refer to page199, the standard
equipment by design, do not continue driv-
ing. Otherwise, a severe accident could
result if you continue driving.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
