Fader is used to determine whether the 
sound focus should be shifted toward the 
front or rear of the vehicle
Select “Sound”  “Balance/Fader”.
The setting last selected is indicated by 
an outlined bar.

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)
Audio CD
MP3
Radio (FM, AM, WB, Satellite)
PCMCIA
AUX
i
Since some DVDs contain both stereo as 
well as multi-channel audio formats, it may be 
necessary to adapt the audio format 
(
page 124).

The “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.

469 Controls in detail
Driving systems
The Park Assist system deactivates at 
speeds over approximately 10 mph 
(16 km/h). At lower speeds the Parktronic 
system turns on again.
Park Assist is also switched off when you 
set the automatic transmission to park 
positionP or switch off the engine.
While the transmission is in neutral 
positionN, Park Assist is switched off if 
you secure the vehicle in place with the 
electronic.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors 
in the front bumper and two sensors in the 
rear bumper.
Range of the sensors
The sensors of the Park Assist system are 
integrated in the front and rear bumpers. 
Make sure that the bumpers are clear of 
dirt, ice and slush in the area of the sen-
sors, as otherwise, Park Assist may not 
function properly, see “Cleaning the driv-
ing systems sensors” (
page 601).Front sensors
Rear sensors
i
Due 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

!
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.

712 Practical hintsTowing the vehicleTowing with all wheels on the ground
Switch on the ignition.
Shift the automatic transmission to 
neutral positionN.
If engaged, manually release the 
electronic parking brake.
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 sup-
ply 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 certain the SmartKey is in 
starter switch position2.
Warning!
G
With the engine not running, there is no 
power assistance for the brake and steering 
systems. In this case, it is important to keep 
in mind that a considerably higher degree of 
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.
!
Keep in mind that it is important to have the 
ignition switched on. As soon as the SmartKey is 
removed from the starter switch or the SmartKey 
with KEYLESS-GO* is removed from the vehicle, 
the automatic transmission will shift to park 
positionP.
!
The vehicle may be towed only for distances 
up to 30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).
i
To signal turns while being towed with the 
hazard warning flasher in use, the ignition must 
be switched on. You can then activate the com-
bination switch for the left or right turn signal in 
the usual manner – only the selected turn signal 
will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
