57 Safety and Security
Occupant safety
PRE-SAFE® takes action in the following in-
stances:

Emergency braking situations, e.g.
when BAS (
page 68) is activated or
when
BAS Plus* (
page 69) is strongly inter-
vening.

Critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded
its physical limitations.

Evasive steering maneuvers at speeds
above 20 mph (30 km/h).
When you are driving faster than 20 mph
(30 km/h), PRE-SAFE
® takes the following
measures in such situations:

The front seat belts are pre-tensioned
electrically.

If the OCS senses that the front pas-
senger seat is occupied and the seat is
in an unfavorable position, it will be
adjusted to a better position.

If the vehicle is equipped with power
adjustable rear seats* and the passen-
ger outer seats are in an unfavorable
position, they will be adjusted to a bet-
ter position.

The system increases the air pressure
in the air pockets (on the sides of the
seat cushion and backrest) of the mul-
ticontour* and/or drive-dynamic front
seats*.

If the vehicle is understeering or over-
steering, the tilt/sliding sunroof and
the door windows also close until only
a small gap remains.
Once the hazardous situation is over with-
out an accident occurring, PRE-SAFE
®
loosens the seat belt pre-tension and de-
creases the air pressure in the air pockets
of the multicontour and drive-dynamic
seats*. You can readjust all of the settings
made by PRE-SAFE
®.If the seat belts do not release:
Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is
properly secured at all times while the
vehicle is in motion.
iIf the closing procedure of the tilt/sliding
sunroof or power windows is blocked, the
tilt/sliding sunroof or power windows will stop
and open slightly.
!When moving the seat, make sure there are
no items in the footwell or behind the seats. Oth-
erwise you could damage the seats.

or
Load CD/DVD (page 115) or a
PCMCIA card (

iBy selecting “LOGIC7® OFF”, all compatible
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.
iPlease 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 128 kbit/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.
iWhen you insert an audio CD or audio DVD,
it automatically becomes the active audio
source.

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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 57).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iIf PRE-SAFE® has been activated, the front
passenger’s seat and/or electrically adjustable
rear seats* will be moved to a more favorable
seat position.
iThe memory function (page 365) lets you
store the settings for the seat positions together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seats, make sure there are
no items in the footwell or behind the seats; oth-
erwise, you could damage the seats.

365 Controls in detail
Memory function
Memory function
Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach, and comfort. The head re-
straint should also be adjusted for proper
height. See also the section on air bags
(
page 42) for proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small chil-
dren should be seated in a properly se-
cured restraint system that complies with
U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213 and
210.2.With the memory function you can store up
to 3 different configurations.
