example. Ther eisanincreased risk of injury.
Never modify part softherestraint systems.
Do no tattemp ttomodify the wiring as well as

In this section ,you will learn the most
important facts about the restraint system

Devices and air bags Durin
gthe firs tstag eofac ollision, the ai rbag

dat arelating to vehicle deceleratio nor
acceleration, suc has:
R duration
R direction
R magnitude
Based on th eevaluation of this data, th eair
bag control unit pre-emptivel ytrigger sthe
Emergency Tensioning Devic einthefirst
stage.
If there is an eve nhigher rat eofvehicle
deceleratio noracceleration in alon gitudinal
direction, the front ai rbags are also deployed.
Your vehicle has adaptive, two-stag efront air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
even tofa collision. In the firs tdeployment
stage, the fron tair bag is filled with enough
propellan tgas to reduc ethe ri sk of injuries.
The front air bag is fully deployed if asecond
deploymen tthreshold is reached within afew
milliseconds.
The Emergency Tensioning Device and air bag
triggering thresholds are variable and are
adapted to the detected rate of deceleration
or acceleration of the vehicle. This process is
pre-emptive in nature. The triggering process
must 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:
R 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
the vehicle has collided
Factors that can only be seen and measured
after acollision has occurred do not play a Occupant safety
41Safety Z

decisive role in the deployment of an air bag,
nor do they provide an indication of air bag
deployment.
The vehicle may be deformed significantly,
e.g. the hood or the fender ,without an air bag
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, air bags 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 aresult.
i The fron tEmergenc yTensioning Devices
can only be triggered if the seat belt
tongues on the fron tseats are correctly
engaged in the seat belt buckles.
i Not all air bags are deployed in an
accident. The differen tair bag systems
work independently of each other.
How the air bag system work sis
determined by predictin gthe severity of
the accident ,especially vehicle
deceleration or acceleration, and the type
of accident:
R head-on collision
R side impact
R rollover
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchorin gpoints
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Ben zCenter.
R Air bags and pyrotechnic Emergency
Tensionin gDevices (ETDs) contain
perchlorat ematerial, which may require
special handlin gand regar dfor the environment. Check your national disposal
guidelines. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETD sare designed to function
on aone-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts ,asthis may
severely weaken them. In acrash, the ymay
not be able to provide adequate protection.
R Do not make any modifications to the SRS
wirin gorc omponents.
R Do not modif yorremove any components
or part softhe SRS.
R Do not install additional trim material, seat
covers, badges, etc .tothe:
- padded steering wheel boss
- knee bag covers
- front-passenger air bag cover
- outer side of front seat bolsters
- outer seat bolsters of the rear bench seat
backrest
- roof frame trim
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep the area between the air bags and
occupant sfree of object s(e.g. packages,
handbags, umbrellas etc.).
R Do not hang any objects such as coat
hangers on the coat hooks or the grab
handle above the door. These items may be
thrown around in the vehicle and cause
head and other injuries when the window
curtain air bag is deployed.
R Air bag system componentsw ill be hot after
an air bag has inflated. Do not touch them.
R Never rest your feet on the dashboard or
the seat. Always keep both feet on the floor
in fron tofthe seat. 42
Occupant safetySafety

R
Improper repairw ork on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefor eonly be
performed by qualified technicians.
Consult an authorized Mercedes-Benz
Center.
R For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These are available from any
authorized Mercedes-Benz Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicabl esection in the Operator's Manual. Air bags
Important safety notes NEVERu
searearward facing child restraint
system on aseat protected by an ACTIVE AIR
BAG in front of it, DEATH or SERIOUS INJURY
to the CHILD can occur. G
WARNING
Using unsuitable seat covers could restric tor
even preven tdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protec tvehicle occupant sas
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat cover sthat have
been approved for the respective seat by
Mercedes-Benz. G
WARNING
The air bag parts are hot after the airbag has
been deployed. There is arisk of injury.
Do not touch the air bag parts. Have the
deployed air bags replaced at aqualified
specialist workshop as soon as possible. G
WARNING
Air bags are designed to reduce the incidence
of injuries and fatalities in certain situations:
R frontal impacts (driver's and front-
passenger fron tair bags and driver's knee
bag)
R side impact s(side impact air bags and
window curtain air bags)
R rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, asmall
amount of powder is released .The powder
generally does not constitute ahealth hazard
and does not indicate that there is afire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening awindow or
door. G
WARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body. Occupant safety
