Surround sound
With surround sound, you can choose be-
tween “LOGIC7
® ON” and “LOGIC7® OFF”.
Harman/kardon LOGIC7
® surround sound
is available for the following operating
modes:

Audio DVD (MLP, DTS, PCM, and Dolby
Digital audio formats)

Video DVD (DTS, PCM, and Dolby Digi-
tal audio formats) (USA only)

Audio CD

MP3

Radio (FM, AM, WB,
Satellite* (USA only))

PCMCIA
iSince some DVDs contain both stereo as
well as multi-channel audio formats, it may be
necessary to adapt the audio format
(
page 123).
iThe “LOGIC7® ON” function of the har-
man/kardon LOGIC7® surround sound system
makes it possible to play discrete 5.1 and stereo
recordings with optimal surround sound for ev-
ery passenger. Music on CDs or audio DVDs with
high-resolution surround formats such as MLP,
DTS or Dolby Digital is played back optimally.
For an ideal sound experience on all seats,
LOGIC7
® distributes 5.1 surround information
via the 13-channel system architecture. The re-
sult is a sound as intended by the sound engi-
neers during the original recording.
harman/kardon LOGIC7
® converts all two-chan-
nel stereo sound material into multi-channel sur-
round sound. With the help of LOGIC7
®,
surround information stored during the original
recording are read out and distributed through
the 13 channels. No effects are created during
this process; only that which was already there
becomes audible.
In addition, harman/kardon LOGIC7
® moves the
perceived sound source away from the individual
loudspeakers, thus generating a natural 360°
sound experience for every passenger.

Driving systems
Front sensors
Rear sensorsWarning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle.
The warning indicator for the front area is
in the instrument cluster. The warning indi-
cator for the rear area is on the roof liner in
the rear.
1Left side of the vehicle
2Right side of the vehicle
3Indicator
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
If yellow indicators 3 under the segments
are lit, Park Assist is ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.
iDue to the sensors’ broad detection range,
it is possible that Park Assist also detects the fol-
lowing obstacles and issues a warning:

obstacles in the ground, e.g. sewer canal
covers, rails, bumps in the road or gutters

obstacles moving upward quickly, e.g. rolling
garage doors
Centerapprox. 40 in (100 cm)
Cornersapprox. 24 in (60 cm)
Centerapprox. 50 in (125 cm)
Cornersapprox. 24 in (60 cm)
!While parking, pay particular attention to ob-
jects over or underneath the sensors, e.g. flower
boxes, an elevated crossbar or a trailer tow
hitch. Park Assist does not detect such nearby
objects. You could otherwise damage the vehicle
or the objects.

700 Practical hints
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as neces-
sary to have the vehicle moved to a safe
location where the recommended towing
methods can be employed.
!Do not tow-start the vehicle.
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing so could
damage the transfer case, which is not covered
by the Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground. Observe
instructions for towing the vehicle with all
wheels on the ground.
!Use flatbed or wheel lift/dolly equipment
with SmartKey or SmartKey with KEYLESS-GO*
in starter switch turned to position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Switch off the ESP
® (page 73) and the auto-
matic central locking (
page 245).
!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension parts.
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run

there is a malfunction in the brake
system

there is a malfunction in the power
supply or in the vehicle’s electrical
system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey or
SmartKey with KEYLESS-GO* is in starter
switch position2.
