Technology for comfort, convenience and
safety
PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed, otherwise the physical circumstances
would mean that the system warning was too
late.<
Switching on automatically
The system starts to operate approx. one sec-
ond after you shift into reverse or move the
selector lever into position R with the engine
running or the ignition switched on.
Wait this short time before driving off.
Switching on manually
Press the button; the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
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. As the distance between
vehicle and object decreases, the intervals
between the tones become shorter. If the dis-
tance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ing jets for long periods and maintain a distance
of at least 4 in/10 cm to them.
PDC with visual warning*
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are already shown there before

Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adaptive brake assistant*
In conjunction with the active cruise control
with the stop-and-go function, the adaptive
brake assistant ensures that the brake
responds even more quickly during braking
with the brake assistant.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not restrict the additional
safety margin with a risky driving style, as other-
wise there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC are deactivated together.
Stabilizing and drive output promoting actions
are no longer executed. The stability-promoting
intervention of the active steering
* is also deac-
tivated, refer to page95.A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.

Operating state of front passenger
airbags
The illustration here shows a possible arrange-
ment in the Coupe. With some vehicle equip-
ment packages or in the Convertible, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front,
knee and side airbags on the front passenger
side depending on whether the seat is occu-
pied. The indicator lamp shows whether the
front passenger airbags are activated or deacti-
vated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front, knee and side airbags on the front
passenger side are deactivated.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehicle is
manufactured. After installing a child's seat,
make sure that the indicator lamp for the front
passenger airbags lights up. This indicates that
the child's seat has been detected and the front
passenger airbags are not activated.<
>The indicator lamp does not light up if, for
example, the system detects a person of
sufficient size seated correctly on the seat.
The front, knee and side airbags on the front
passenger side are activated.
>The indicator lamp does not light up when
the seat is empty.
But the front, knee and side airbags on the
front passenger side are still deactivated.
Operational readiness of airbag system
From radio readiness, refer to page60, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction, otherwise
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<
Convertible: rollover
protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal axis, or loss of ground contact. The
rollover bars located behind the rear head
restraints are deployed within fractions of a sec-
ond.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path of movement of the
rollover protection system clear.
In minor accidents, you are protected by the
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and
multi-phase airbag retention system.<

Press the button on the steering wheel.
>The two lines1 indicate that the system is
activated.
>The two arrows2 mean that the system has
detected one or two lane limit lines from a
speed of approx. 40 mph/70 km/h and
warns accordingly.
If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>after approx. 3 seconds
>if you return to your lane
>if you brake heavily
>if you signal
System limits
The leaving lane warning cannot serve as
a substitute for your personal judgment in
determining the course of the road.
If the system issues a warning, do not move the
steering wheel with unnecessary severity, as
otherwise you could loose control of the vehi-
cle.<
The function of the system may be limited in the
following example situations:
>in heavy fog, rain or snowfall
>with worn-away, poorly visible limit lines, or
lines that run together or apart or are
unclear, e.g. in road construction areas
>when limit lines are covered by snow, ice,
dirt or a great deal of water
>in tight curves or on narrow roads>when limit lines are not white
>when limit lines are covered by objects
>when driving up close behind a vehicle driv-
ing ahead
>with bright counter light
>when the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror

>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horse-drawn vehicles, railroad
or shipping traffic close to the road, and at
deer crossings
>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of highly reflective signs
>in the low speed range>when the windshield is fogged up, dirty or
covered with stickers, decals etc. in the area
of the inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.
