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
Rollover
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
Emergency Tensioning
Devices
Driver's airbag, front
passenger front air‐
bag
Detected deploy‐
ment situation
Frontal impact, rear

Only if the vehicle is equipped with a side air‐
bag or window curtain airbag.
& WARNING Risk of burns from hot air bag
components
The air bag parts are hot after an air bag has
been deployed.
Do not touch the air bag parts.
#
Have a deployed air bag replaced at a
#
qualified specialist workshop as soon as
possible.
For your safety and that of your passengers, it is
recommended that you have the vehicle towed to
a qualified specialist workshop after an accident.
Take this into account, particularly if an Emer‐
gency Tensioning Device is triggered or an airbag
deployed.
If the Emergency Tensioning Devices are trig‐
gered or an airbag 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.
Airbags and pyrotechnic Emergency Tensioning
Devices contain perchlorate material, which may
require special handling or environmental protec‐
tion measures. National guidelines regarding
waste disposal must be observed. In California,
