62 Safety and SecurityOccupant safetyInfant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. To deacti-
vate the special seat belt retractor for the
front passenger seat, the front passenger
seat must be in the most backward posi-
tion. The seat belt can again be used in the
usual manner.
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.i

tings for tether anchorages (

!
The use of infant or child restraints is re-
quired by law in all 50 states, the District of Co-
lumbia, the U.S. territories and all Canadian
provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system prop-
erly secured by a lap/shoulder belt or, if so
equipped, a top tether anchorage point and a
child restraint lower anchorage system that
complies with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian Motor Ve-
hicle Safety Standard 213 and 210.2.
A statement by the child restraint manufacturer
of compliance with this standard can be found
on the instruction label on the restraint and in
the instruction manual provided with the re-
straint.
When using any infant or child restraint system,
make sure to carefully read and follow all manu-
facturer’s instructions for installation and use.
Please read and observe warning labels affixed
to the inside of the vehicle and to infant or child
restraints.Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant, or toddler restraint, or
booster seat recommended for the size and
weight of the child.

Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
1Cover of top anchorage ring
Bring the rear power seat backrest* to
a fully upright position (
page 320).

Remove cover1 from anchorage ring.

Store cover1 in a convenient place
(e.g. glove box).

Guide tether strap between head re-
straint and top of seat back.
Warning!
G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children over 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.

65 Safety and Security
Occupant safety
Head restraints must be positioned such
that the top tether strap can pass freely
between the head restraint and top of seat
back.
Make sure the tether strap is not twist-
ed.

3Anchorage ring

Securely fasten hook2, which is part
of the tether strap, to anchorage
ring3.Once the top tether anchorage hook is at-
tached, the child restraint itself can be se-
cured. Tighten the top tether strap
according to the child restraint manufac-
turer’s instructions.

Reinstall cover after removing the
tether strap.Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L
ower A
nchors and T
ethers for CH
ildren)
type anchors (at each of the rear seats) for
the installation of a LATCH child seat with
the matching anchor fittings.
If you have not installed a child seat, the
LATCH anchor are covered with an uphol-
stery blend.

Vehicles with adjustable rear seats/bench*:
Never adjust the rear seat position after in-
stalling the child restraint. Adjusting the rear
seat position after installing the child re-
straint could damage the child restraint
and/or introduce undesirable slack or ten-
sion into the seat belt and loosen or mispo-
sition the child restraint, lessening the
effectiveness of the child restraint and thus

Digital audio formats)


Audio CD

PCMCIA
i
Since some DVDs contain both stereo as
well as multi-channel audio formats, it may be
necessary to adapt the audio format
(
page 114).
i
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.

By selecting “LOGIC7

formats as they are present on the medium are
played back. Due to the vehicle’s spatial charac-
teristics, an optimal sound experience is not en-
sured on all seats.
i
Please note the following:


For an ideal sound experience at all seats,
the balance and fader should be adjusted to
the center of the passenger compartment
with LOGIC7
® switched on.


The best sound results are achieved by play-
ing high-quality audio CDs and audio DVDs.


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


Surround sound does not function for
mono-signal sources.


In the event of poor radio reception quality,
e.g. inside a tunnel, you should switch off
LOGIC7®, as a dynamic switch from Stereo
to Mono could occur, resulting in temporary
sound distortion.


With some stereo recordings, the resulting
sound may deviate from conventional stereo
playback.
i
When you insert an audio CD or audio DVD,
it automatically becomes the active audio
source.
