WARNING
If the restraint system is modified ,itmay no
longer work as intended .The restraint system
may then not perfor mits intended protective
function by failing in an accident or triggering
unexpectedly, for example. There is an
increased ris kofinjury ,possibly eve nfatal.
Neve rmodify parts of the restraint system. Do
not attempt to modify the wiring as well as
electronic components or thei rsoftware.
If it is necessary to modify an airba gsystem to
accommodate aperson with disabilities, con-
tact aMercedes-Benz Service Centre for
details. Restrain

When deployed, the windowbag enhances the
level of protection for the head. However, it
does not protec tthe chest or arms.
In the event of aside impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, awindowbag may be deployed in
other accident situation s(Ypage 53). Deployment of belt tensioners and air-
bags
Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is arisk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at aqualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at aqualified specialist workshop.
Mercedes-Benz recommends that you have
the vehicle towed to aqualified specialist
workshop after an accident .Take this into
account ,particularly if aseat belt tensioner
was triggered or an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If the belt tensioners are triggered or an air-
bag is deployed, you will hear abang, and a
small amount of powder may also be released. The
6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your
hearing. In general, the powder released is
not hazardous to health but may cause short- term breathin gdifficulties to persons suffer-
ing from asthma or other pulmonary condi-
tions. Provided it is safe to do so, you should
leave the vehicle immediately or open the
window in order to preven tbreathin gdifficul-
ties.
Operation During the first stage of
acollision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit trigger sthe seat
belt tensioners in the event of ahead-on or
rear collision.
As eat belt tensioner can only be triggered if:
R the ignition is switched on
R the componentsoft he restraint system are
operational; see "Restraint system warning lamp" (Y page 45)
R the belt tongue has engaged in the belt
buckle of the respective fron tseat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
If the restraint system control unit detect sa
high severit yofanaccident,incertain head-
on collisions, additional componentsoft he
restraint system are deployed independently
of each another:
R Fron tairbags and driver's kneebag
R Windowbag, if the system determines that
deployment can offer additional protection

vehicles with the memory function: the
front-passenge rseat 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 backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the beltp re-tensioning. On vehicles with mul-
ticontour seats/active multicontour seats,
the air pressure in the side bolsters is reduced
again. All settings made by PRE-SAFE ®
can
then be reversed.
If the seat beltp re-tensioning is not reduced:
X Move the seat backrest or seat back

Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the rada rsensor system, PRE-SAFE ®
PLUS is abletod etect thatahead-on or rear-
end collision is imminent. In certain hazard-
ous situations, PRE-SAFE ®
PLUS takes pre-
emptive measures to protect the vehicle
occupants.
Important safety notes The intervention of PRE-SAFE
®

prevent an imminent collision.
The drive risnot warned before the interven-
tion of PRE-SAFE ®

®
PLUS does not intervene:
R if the vehicl eisreversing
R when the vehicl eistowing atrailer and
there is arisk of arear-end collision
PRE-SAFE ®
PLUS does not perform braking
actions while the vehicl eisinmotion or when
Parking Guidance is active.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the rada rsensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following meas-
ures depending on the hazardous situation
detected:
R If the rada rsensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R If the rada rsensor system detects that a
rear-end collision is imminent:
- the rear hazard warning lamp sare acti-
vated and flas hatahigher frequency.
- the brake pressure is increase difthe
drive rappliest he brakes when the vehi-
cle is stationary.
- the seat belts are pre-tensioned.
The PRE-SAFE ®

cancelled:
R if the accelerator peda lisdepressed when
ag earise ngaged
R if the risk of acollision passes or is no lon-
ger detected
R if DISTRONIC PLUS indicates an intention

Important safety notes G
WARNING
If the integrated child seat or the ICS padded play table is modified, damaged or subjected
to aload in an accident, it cannot perform its
intended protective function. Achild there-
fore cannot be restrained in the event of an
accident, heavy braking or asudden change of
direction. This poses an increased risk of
injury or even fatal injury.
Immediately replace an integrated child seat
or ICS padded play table that has been modi- fied, damaged or subjected to aheavy load as
the result of an accident. Only use the ICS
padded play table with its original cover or
with acover that has been approved by the
manufacturer, and do not used aprotective
cover. G
WARNING
If the ICS padded play table is exposed to
direct sunlight or heat, parts could heat up.
Children could suffer burns on these parts,
particularly on metallic parts. There is arisk of
injury.
If you and your child leave the vehicle, cover
the ICS padded play table so that it is not
exposed to direct sunlight and heat. If the ICS padded play table has been exposed to direct sunlight, allow it to cool before securing a
child to it. Never leave children unattended in
the vehicle.
Observe the notes on the ICS paddedp lay
table (Y page 63).
The integrated child seats are integrated into the seat cushions of the outer rear seats. In
conjunction with the componentsl isted in thefollowing table, they comply with the legal
