the vehicle occupants in the event of ac rash.
G WARNING
Emergenc yT ensioning Devices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perfor mt heir inten-
ded protective function .T his poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.

ger the tightenin goft he seat belt in hazardous
situations. This procedure is reversible.
If Emergenc yT ensioning Devices are triggered
or air bags are deployed, you will hear ab ang,
and as mall amount of powder may also be
released. The u restraint system warning
lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute ah ealth hazard, but it may cause
short-term breathin gd ifficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre-
vent breathin gd ifficulties.
Air bags and pyrotechnic Emergenc yT ensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
Method of operation Durin gt he first stage of ac ollision, the restraint
system control unit evaluates important physi-
cal data relatin gtov ehicle deceleration or accel-
eration ,s uch as:R
duration R
direction R
intensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
genc yT ensioning Devices during af rontal or
rear collision. An Emergenc yT ensioning Devic ec an only be
triggered, if: R
the ignition is switched on R
the component soft he restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
( Y
page 37) R
the belt tongue has engaged in the belt buckle
of the respective seat
If the restraint system control unit detects a
more severe accident, further component so f
the restraint system are activated independ-
ently of each other in certain frontal collision
situations: R
Fron ta ir bags as well as driver' sa nd front-
passenger knee bags
The front-passenger fron ta ir bag is activated or
deactivated dependin gont he person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an acciden tift he
PASSENGER AIR BA GONi ndicator lamp is lit.
Observe the information on the PASSENGER AIR
BA Gi ndicator lamps ( Y
page 38).
Your vehicle has two-stage fron ta ir bags. During
the first deployment stage, the fron ta ir bag is
filled with propellant gas to reduce the risk of
injuries. The fron ta ir bag is fully deployed with
the maximum amount of propellant gas if as ec-
ond deployment threshold is reached within a
few milliseconds.
The activation threshold of the Emergenc yT en-
sionin gD evices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various point si n
the vehicle. This proces sisp re-emptive in
nature. Deploymen ts hould take place in good
time at the start of the collision.
The rat e
of vehicle deceleration or acceleration
and the direction of the forc ea re essentially
determined by: R
the distribution of forces during the collision R
the collision angle R
the deformation characteristic soft he vehicleR
the characteristic soft he objec tw ith which
the vehicle has collided
Factors which can only be seen and measured
after ac ollision has occurred do not play ad eci-
sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case ifOccupant safety 49
Safety Z

only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as ar esult.
If the control unit of the restraint system detects
as ide impact or av ehicle rollover, the relevant
components of the restraint system are activa-
ted separately depending on the anticipated
type of accident. R
Side impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the
driver's seat
The side impact air bag on the front-
passenger side deploys under the following
conditions: -
the OCS system detect st hat the front-
passenger seat is occupied or -
the belt tongue is engaged in the belt
buckle of the front-passenger seat R
Head bag on the side of impact, independ-
ently of the use of the seat belt and inde-
pendently of whether the front-passenger
seat is occupied R
Emergency Tensionin gD evices, if the system
determines that deployment can offer addi-
tional protection in this situation R
Head bags on the driver's and front-
passenger side in certain situations when the
vehicle rolls over, if the system determines
that deployment can offer additional protec-
tion to that provided by the seat belt
i Not all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident: R
Frontal collision R
Side impact R
Rollover NECK-PRO head restraints
Important safety notes
G WARNING
The function of the head restraint may be
impaired if you: R
attach object ss uch as coat hangers to the
head restraints, for example R
use head restraint covers
If you do so, the head restraint sc annot fulfill
their intended protective function in the event
of an accident .Ina ddition, object sa ttached
to the head restraint sc ould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any object stot he head
restraint sa nd do not use head restraint cov-
ers.
Method of operation NECK-PRO head restraint sr educe the likelihood
of head and chest injuries. The NECK-PRO head
restraint sont he driver's and front-passenger
seats are moved forwards and upwards in the
event of ar ear-end collision of ac ertain severity.
This provides better head support.
If the NECK-PRO head restraint sh ave been trig-
gered in an accident ,y ou must reset the NECK-
PRO head restraint sont he driver’s and front-
passenger seat ( Y
page 51). Otherwise, the
additional protection will not be available in the
event of another rear-end collision. You can rec-
ognize when NECK-PRO head restraint sh ave
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraint sc hecked for func-
tionality at aq ualified specialist workshop after
ar ear-end collision.50
