When deployed, the windowbag enhances the
level of protection for the head. However, it
does not protect the chest or arms.
In the event of a side 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, a windowbag may be deployed in
other accident situations (

Deployment of belt tensioners and air-
bags
Important safety notes
G WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified 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 a qualified specialist workshop.
Mercedes-Benz recommends that you have
the vehicle towed to a qualified specialist
workshop after an accident. Take this into
account, particularly if a seat 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 a bang, and a
small amount of powder may also be
released. The 6 restraint 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 breathing difficulties 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 prevent breathing difficul-
ties.
Operation
During the first stage of a collision, 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 triggers the seat
belt tensioners in the event of a head-on or
rear collision.
A seat belt tensioner can only be triggered if:
R
the ignition is switched on
R
the components of the 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 front seat
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 detects a
high severity of an accident, in certain head-
on collisions, additional components of the
restraint system are deployed independently
of each another:
R
Front airbags and driver's kneebag
R
Windowbag, if the system determines that
deployment can offer additional protection
to that provided by the seat belt
