Occupant safety

Your vehicle has two-stage front airbags. In the
first deployment stage, the front airbag is filled
with propellant gas to reduce the risk of injuries.
The front airbag is fully deployed if the second
deployment stage is activated within a few mil-
liseconds.
The activation threshold for the seat belt ten-
sioners and airbags is determined based on the
evaluation of the vehicle's rate of deceleration
or acceleration at various points in the vehicle.
This process is pre-emptive in nature. The trig-
gering/deployment process should take place
in good time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
the distribution of forces during the collision
R
the collision angle
R
the deformation characteristics of the vehicle
R
the characteristics of the object with which
R
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-
sive role in the deployment of an airbag, nor do
they provide an indication of airbag deployment.
The vehicle may be deformed significantly with-
out an airbag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, an airbag may be deployed
even though the vehicle suffers only minor
deformation. This is the case if, for example,
very rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as a result.
If the restraint system control unit detects a side
impact or if the vehicle overturns, the applicable
components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
Sidebag on the side on which an impact
R
occurs, independent from the seat belt ten-
sioner and seat belt usage
The sidebag on the front-passenger side
deploys under the following conditions:
an occupant is detected on the front-
-
passenger seat or
the belt tongue is engaged in the belt
-
buckle of the front-passenger seat
Headbag on the side on which an impact
R
occurs, independent of seat belt usage and
regardless of whether the front-passenger
seat is occupied
Seat belt tensioners, if the system determines
R
that deployment can offer additional protec-
tion for the vehicle occupants in this situation
Headbags on the driver's and front-passenger
R
side in certain situations if the vehicle over-
turns and if the system determines that
deployment can offer additional protection to
that provided by the seat belt
i
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other.
How the airbag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
frontal collision
R
side impact
R
overturn

Important safety notes
G
WARNING
The function of the head restraint may be
impaired if you:
attach objects such as coat hangers to the
R
head restraints, for example
use unsuitable head restraint covers
R
If you do so, the head restraints cannot fulfil
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. This poses an increased
risk of injury.
Do not attach any objects to the head
restraints and only use suitable head restraint
covers.
Consult a Mercedes-Benz Service Centre
regarding the availability of suitable seat or head
restraint covers.
