protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R when BAS activates, e.g. in emergency
braking situations
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detectsani mminent
dange rofcollision in certain situations
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R vehicles with amulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and back-
rest is increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only asmall gap
remains.
If the hazardous situation passes without
resulting in an accident ,PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set- tings made by PRE-SAFE
®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
lockin gmechanism is released.

WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupant s—in
particular, pregnan twomen —wear their seat
belts correctly at all times.
R The seat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. awinter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder

seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it wouldn ot be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting achild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. acushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in achild
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys- tem could heat up and the child could burn
herself/himself on them.
If
ac hild opens adoor, the child or other per-
sons could be injured as aresult. They could
get out and injure themselves or be injured by
ap assing vehicle.
Observe the general notes on the HOLD func-
tion, which can be found under the same key-
word. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R sudden braking
R as udden change of direction
Do not transport heavy or hard objects in the
vehicle interior unless they are secured. You
will find further information under "Loading
guidelines" in the index.
If ac hild is travelling in your vehicle, secure
the child using achild restraint system which
is recommended for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Ideallyt he child restraint system should be
installed on asuitabler ear seat. Make sure
that the child is secured for the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 60). You can obtain further infor-
mation aboutt he correct child restraint sys-
tem from any Mercedes-Ben zService Centre.

R
only use aforward-facin gchild restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2. If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by
aspecial sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: when you
turn the key to position 2inthe ignition lock,
the 4 PASSENGER AIRBAG OFF indicator
lamp lights up briefly, but does not have any
function. It does not indicate that there is
automatic child seat recognition on the front-
passenger seat. The front-passenger seat sensor system for
child restraint systems detectsw
hether a
special Mercedes-Ben zchild seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case, 4
