event data recorder (EDR). The main purpose of
an EDRistor ecord, in certain crash or near
crash-lik esituations, such as an air bag deploy-
ment or hittin garoad obstacle, data that will
assist in understanding how avehicle's systems
performed. The ED Risdesigned to record data
related to vehicle dynamics and safety systems
for ashort period of time, typically 30 seconds
or less. The ED
Rinthis vehicle is designed to record
such data as:
RHow various systems in your vehicle were
operating
RWhether or not the driver and passenger
safety belts were buckled/fastened
RHow far (if at all) the driver was depressing the accelerator and/or brake pedal and
RHow fast the vehicle was traveling.
These data can help provide abetter under-
standin gofthe circumstances in which acci-
dents and injuries occur. NOTE: ED Rdata are
recorded by your vehicle only if anon-trivial
crash situation occurs; no data is recorded by
the ED Runder normal driving conditions and no
personal data (e.g. name, gender, age and acci-
dent location) are recorded. However, other par- ties, such as law enforcement could combine
ED Rd ata with the type of personally identifying
data routinely acquired during acrash investi-
gation.
Access to the vehicle and/or the ED Risneeded
to read data that is recorded by the EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment,c an read the information by accessing the
vehicle or the EDR.

Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Alway shave work on the doors or door pan-
eling carried out at aqualifieds pecialist work-

Front air bags
!Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied .Inthe
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.

If the front passenger does not observe these
conditions, OCS may produceafalse classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on avehicle armrest
Rsits in such away that their weight is raised
from the seat cushion
If you install achild restraint system on the
front-passenger seat, be sure to observe the
correct positioning of the child restraint system.
Never place objects under or behind the child
restraint system, e.g. acushion. The entire base
of the child restraint system must always rest on
the seat cushio nofthe front-passenger seat.
The backrest of the forward-facing child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat.
The child restraint system must not touch the
roof or be subjected to aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint positiona ccordingly.
Only then can OCS be guaranteed to function
correctly. Alway sobserve the child restraint sys-
tem manufacturer's installation and operating
instructions.

Ypage 187). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the front-passenger front air bag both before
and during the journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled.Itw illnot be deployed in the event of
an accident and cannot perform its intended
protective function. Aperson in the front-
passenger seat could then, for example ,come
into contact with the vehicle's interior, espe-
ciallyift he person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.

For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories that
have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag will
also deploy.T he Occupant Classification Sys-
tem (OCS) categorizes the occupant in the front-
passenger seat. Depending on that result, the
front-passenger front air bag is either enabled or
deactivated.
System self-test
GDANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered at all
in the event of an accident with high deceler-
ation. This poses an increased risk of injury or
even fatal injury.
In this case the front-passenger seat may not
be used. Do not install achild restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at aqualified spe-
cialist workshop.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when aperson is seated in the front-
passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or
even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe person is seated properly with acor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved
as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat may not be used. Do not
install achild restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at aqualified specialist work-
shop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passenger
air bag not functioningasi ntended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible,ber esting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator

If Emergenc yTensioning Devices are triggered
or air bags are deployed, you will hear abang,
and asmall amount of powder may also be
released. The 6restraint 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 ahealth hazard, but it may cause
short-term breathin gdifficulties 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 gdifficulties.
Air bags and pyrotechnic Emergenc yTensioning
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
Duringthe first stage of acollision, the restraint
system control unit evaluates important physi-
cal data relatin gtovehicle deceleration or accel-
eration ,such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
genc yTensioning Devices during afrontal or
rear collision. An Emergenc
yTensioning Devic ecan only be
triggered, if:
Rthe ignition is switched on
Rthe component softhe restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(
Ypage 37)
Rthe 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 sof
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RFronta ir bags as well as driver'sa nd front-
passenger knee bags
The front-passenger fronta ir bag is activated or
deactivated dependin gonthe person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an accidentift he
PASSENGER AIR BAGONi ndicator lamp is lit.
Observe the information on the PASSENGER AIR
BAGi ndicator lamps (
Ypage 38).
Your vehicle has two-stage fronta ir bags. During
the first deployment stage, the fronta ir bag is
filled with propellant gas to reduce the risk of
injuries. The fronta ir bag is fully deployed with
the maximum amount of propellant gas if asec-
ond deployment threshold is reached within a
few milliseconds.
The activation threshold of the Emergenc yTen-
sionin gDevices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various point sin
the vehicle. This processisp re-emptive in
nature. Deploymen tshould take place in good
time at the start of the collision.
The rat
e of vehicle deceleration or acceleration
and the direction of the forcea re essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristic softhe vehicle
Rthe characteristic softhe objec twith which
the vehicle has collided
Factors which can only be seen and measured
after acollision has occurred do not play adeci-
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 if
Occupant safety49
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
asaresult.
If the control unit of the restraint system detects
as ide impact or avehicle rollover, the relevant
components of the restraint system are activa-
ted separately depending on the anticipated
type of accident.
RSide 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 sthat the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat

tion to that provided by the seat belt
iNot 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:

NECK-PRO head restraints
Important safety notes
GWARNING
The function of the head restraint may be
impaired if you:
Rattach object ssuch as coat hangers to the
head restraints, for example
Ruse head restraint covers
If you do so, the head restraint scannot fulfill
their intended protective function in the event of an accident.Ina ddition, objectsattached
to the head restraint scould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any object stothe head
restraint sand do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraint sreduce the likelihood
of head and chest injuries. The NECK-PRO head
restraint sonthe driver's and front-passenger
seats are moved forwards and upwards in the
event of arear-end collision of acertain severity.
This provides better head support.
If the NECK-PRO head restraint shave been trig-
gered in an accident,y ou must reset the NECK-
PRO head restraint sonthe driver’s and front-
passenger seat (
Ypage 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 shave
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 schecked for func-
tionality at aqualified specialist workshop after
ar ear-end collision.
