Occupant safety
Have the restraint system checked and
#
repaired immediately at a qualified spe‐
cialist workshop.
Function of the restraint system in an acci‐
dent
How the restraint system works is determined by
the severity of the impact detected and the type
of accident anticipated:
Frontal impact
R
Rear impact
R
Side impact
R
The activation thresholds for the components of
the restraint system are determined based on the
evaluation of the sensor values measured at vari‐
ous points in the vehicle. This process is pre-
emptive in nature. The triggering/deployment of
the components of the restraint system must
take place in good time at the start of the colli‐
sion.
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 vehicle deceleration
is not high. Conversely, an airbag may be
deployed even though the vehicle suffers only
minor deformation. If very rigid vehicle parts such
as longitudinal members are hit, for example, this
may result in sufficiently high levels of vehicle
deceleration.
The components of the restraint system can
be activated or deployed independently of
each other:
Component

Driver's airbag, front
passenger front air‐
bag
Side impact airbag
Window airbag

ment situation

Only if the vehicle is equipped with a side
impact airbag or window airbag.
& WARNING Rick of burns from hot airbag
components
The airbag parts are hot after an airbag has
been deployed.
Do not touch the airbag parts.
#
Have a deployed airbag replaced at a
#
qualified specialist workshop as soon as
possible.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. Take this into account, particu‐
larly if a seat belt tensioner is triggered or an air‐
bag deployed.
If the seat 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 bang will not generally affect your hear‐
R
ing.
In general, the powder released is not hazard‐
R
ous to health but may cause short-term
breathing difficulties to persons suffering
from asthma or other pulmonary conditions.
Provided it is safe to do so, leave the vehicle
immediately or open the window in order to
prevent breathing difficulties.

Seat belts

Protection provided by the seat belt
Always fasten your seat belt correctly before
starting a journey. A seat belt can only provide
the best level of protection if it is worn correctly.
& WARNING Risk of injury or death due to
incorrectly fastened seat belt
If the seat belt is not worn correctly, it cannot
perform its intended protective function.
In addition, an incorrectly fastened seat belt
can also cause injuries, for example, in the
event of an accident or when braking or
changing direction suddenly.
Always ensure that all vehicle occupants
#
have their seat belts fastened correctly
and are sitting properly.
