ous points in the vehicle. This process is pre-emp-
tive in nature. The triggering/deployment of the
components of the restraint system should take
place in good time at the start of the collision.
Factors which can only be seen and measured
a er a collision has occurred cannot play a deci-
sive role in airbag deployment. Nor do they provide
an indication of airbag deployment.
The vehicle may be deformed signi cantly without
an airbag being deployed. This is the case if only
parts which are relatively easily deformed are
a ected and the rate of vehicle deceleration is not
high. Conversely, an airbag may be deployed even
though the vehicle su ers only minor deformation.
If very rigid vehicle parts, such as longitudinal
members, are hit, the vehicle deceleration may be
high enough for this to happen.
Depending on the detected deployment situation,
the components of the restraint system can be
activated or deployed independently of each other:
Emergency Tensioning Device: frontal impact,
R
rear impact, side impact, overturn, rollover
Driver's airbag, front passenger airbag: frontal
R
impact
Side airbag: side impact
R
Window airbag: side impact, overturn, rollover,
R
frontal impact
The co-driver airbag can only be deployed in the
event of an accident if the PASSENGER AIR BAG
OFF indicator lamp is o . If the co-driver seat is
occupied, make sure, both before and during the
journey, that the status of the co-driver airbag is
correct ( page 32).

ARNING Risk of burns from hot air bag
components
The air bag parts are hot a er an air bag has
been deployed.
Do not touch the air bag parts.
#
Have a deployed air bag replaced at a
#
quali ed specialist workshop as soon as
possible.
Mercedes-Benz recommends that you have the
vehicle towed to a quali ed specialist workshop
a er an accident. Take this into account, particu-
larly if an Emergency Tensioning Device is trig-
gered or an airbag deployed.
If the Emergency Tensioning Devices are triggered
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 a ect your hearing.
R
In general, the powder released is not hazard-
R
ous to health but may cause short-term breath-
ing di culties to persons su ering 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 di culties.
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 see
https://dtsc.ca.gov/. You can use the search
function to nd information on perchlorate, for
example.

Always fasten your seat belt correctly before start-
ing a journey. Only a seat belt which is worn cor-
rectly can provide the intended level of protection.

ARNING 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 chang-
ing direction suddenly.
Always ensure that all vehicle occupants
#
have their seat belts fastened correctly
and are sitting properly.
Always observe the instructions about the correct
driver's seat position and adjusting the seat
( page 61).

In order for the correctly worn seat belt to provide
the intended level of protection, each vehicle occu-
pant must observe the following information:
The seat belt must not be twisted and must t
R
tightly and snugly across the body.
The seat belt must be routed across the center
R
of the shoulder and as low down across the
hips as possible.
