Fastening the seat belts

Check your seat belt during travel to
make sure it is properly positioned.

Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.For more information, see “Seat belts”
(
page 46).
Seat belt height adjustment
You can adjust the height of the seat belt
for the driver’s and front passenger seat.
1Release button
Raising: Slide the seat belt height ad-
juster upward.
The seat belt height adjuster engages
in different positions.
Lowering: Press and hold release
button1.
Slide the seat belt height adjuster
downward.
Release button1 and make sure the
seat belt height adjuster engages into
place.
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or seat belts that were
highly stressed in an accident must be re-
placed. Contact an authorized
Mercedes-Benz Center.

Audio system
Adjusting surround sound
With surround sound, you can choose be-
tween
LOGIC7® On and LOGIC7® Off.

Sound.
A dot R indicates the current setting.

To exit menu without saving: Press
button í or slideomp.
iThe LOGIC7® On function of the
harman/kardon LOGIC7® Surround Sound sys-
tem permits the playback of discrete 5.1 and ste-
reo recordings with an optimal surround sound
platform for each passenger.
The LOGIC7
® distributes the 5.1 surround infor-
mation over the 13-channel system architecture
to provide the optimum sound experience from
all seats. This produces the sound characteristic
as intended by the sound engineer during the
original recording.
Harman/kardon LOGIC7
® converts all two-chan-
nel stereo sound material into multi-channel sur-
round sound. The surround information stored
during the original recording is read out using
LOGIC7
® and likewise distributed over the
13 channels. No effects are created during this
process; only that which was already there be-
comes audible.
In addition, harman/kardon LOGIC7
® moves the
perceived sound source away from the individual
loudspeakers, thus generating a natural 360°
sound experience for each passenger.
iBy selecting LOGIC7® Off, all compatible
formats are played back as they are present on
the medium. Due to the vehicle’s spatial charac-
teristics, an optimal sound experience is not en-
sured from all seats.
iBalance and fader will be set to the default
value (0/0) automatically by activating or deacti-
vating LOGIC7
®.
iPlease note the following:

For an optimal sound experience from all
seats, the balance and fader should be ad-
justed to the center of the passenger com-
partment with LOGIC7
® switched on.

The best sound results are achieved when
playing high-quality audio CDs.

For MP3 tracks, the bit rate should be at
least 128 kbit/s.

Surround playback cannot be activated in
mono-signal sources as AM or Weatherband.
It will not function for mono-signal sources
as, e.g. mono audio tracks on some specific
audio CDs.

In the case of poor radio reception quality,
e.g. in tunnels, LOGIC7® should be switched
off, as otherwise a dynamic switchover from
stereo to mono and thus temporary sound
characteristic shifts can occur.

With certain stereo recordings, the resulting
sound characteristic may deviate from con-
ventional stereo playback.

Floormats*
1Eyelet
2Retainer pinRemoving
Pull floormat off of retainer pins2.
Remove the floormat.
Installing
Lay down the floormat in the respective
footwell.
Press the floormat eyelets1 onto re-
tainer pins2.
Warning!G
Whenever you are using floormats, make
sure there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fas-
tened using the eyelets and the retainer
pins.
Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.
iTo install or remove the floormat more easi-
ly, move the driver’s seat or front passenger seat
as far to the rear as possible (
page 85).

427 Practical hints
Resetting activated head restraints
Resetting activated head restraints
If the active head restraints (front seats)
have been triggered in an accident, the ac-
tive head restraints must be reset. Other-
wise, the active head restraints cannot
offer any additional protection in the event
of another rear-end collision.
You can tell that the head restraints have
been triggered when they have been
moved forward and cannot be adjusted.
1Fold back
2Push back
3Push downPush the head restraint cushion by the
bottom, back as far as it will go2.
Push the head restraint cushion down
into the guide as far as it will go3.
Fold the head restraint cushion by the
top, back firmly until it engages1.
Repeat this procedure on the active
head restraints for second head re-
straint.
For information on active head restraints,
see “Active head restraints” (
page 50).
For information on head restraint adjust-
ment, see “Adjusting rear head restraints”
(
page 89).
Warning!G
For safety reasons, have the active head
restraints checked at an authorized
Mercedes-Benz Center after a rear-end
collision.
Warning!G
When pushing back the head restraint cush-
ion, take care that your fingers do not be-
come caught between the head restraint
cushion and the cover. Failing to do so may
lead to injury.
iFor your convenience, we recommend that
you have this work carried out at an authorized
Mercedes-Benz Center.
