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

Since some DVDs contain both stereo as
well as multi-channel audio formats, it may be
necessary to adapt the audio format
(

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.

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.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.

739 Practical hints
Towing the vehicle
Towing 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.
