The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. More detailed infor-
mation is obtained from it, if required.
After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec-
tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to a person.
Examples include: R
accident reports R
damage to the vehicle R
witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
example, vehicle location in case of an emer-
gency.
COMAND/mbrace If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Operator's
Manual and/or the mbrace Terms and Condi-
tions.
Event data recorders This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deploy-
ment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed to record
such data as: R
How various systems in your vehicle were
operating R
Whether or not the driver and passenger
safety belts were buckled/fastened R
How far (if at all) the driver was depressing the
accelerator and/or brake pedal and R
How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which acci-
dents and injuries occur. NOTE: EDR data are
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by
the EDR under 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
EDR data with the type of personally identifying
data routinely acquired during a crash investi-
gation.
Access to the vehicle and/or the EDR is needed
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, can read the information by accessing the
vehicle or the EDR.
EDR data may be used in civil and criminal mat-
ters as a tool in accident reconstruction, acci-
dent claims and vehicle safety. Since the Crash
Data Retrieval CDR tool that is used to extract
data from the EDR is commercially available,
Mercedes-Benz USA, LLC ("MBUSA") expressly
disclaims any and all liability arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or, if
t he vehicle is leased, without the consent of the
lessee. Exceptions to this representation
include responses to subpoenas by law enforce-
ment; by federal, state or local government; in
connection with or arising out of litigation involv-
ing MBUSA or its subsidiaries and affiliates; or,
as required by law.
Warning: The EDR is a component of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the EDR component
may result in a malfunction of the Restraint Sys-
tem Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted.Data stored in the vehicle 31

Occupant safety
Introduction to the restraint system The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
Furthermore, the restraint system may also
reduce the forces exerted on the vehicle occu-
pants when an accident occurs.
The restraint system includes: R
Seat belt system R
Air bags R
Child restraint system R
Child seat securing system
The components of the restraint system work in
conjunction with each other. They can only offer
the intended level of protection if all vehicle
occupants: R
are correctly wearing their seat belts.
( Y
page 44) R
adjust their seat and head restraint properly
( Y
page 94). The driver is also responsible for ensuring that
the steering wheel has been correctly posi-
tioned. Observe the information relating to the
correct driver's seat position ( Y
page 94).
Always ensure the air bag can inflate properly if
deployed ( Y
page 46).
An air bag supplements a correctly fastened
seat belt. As an additional safety device, the air
bag increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection already provided by a cor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags
that would increase the degree of protection
afforded to the vehicle occupants in the event of
an accident are deployed. Seat belts and air
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on restraint system operation can
be found under "Triggering of Emergency Ten-
sioning Devices and air bags" ( Y
page 53).
See “Children in the vehicle” for information on
children traveling with you as well as vehicle
restraint systems ( Y
page 58).
Important safety notes
G WARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1 ‑ 800 ‑ 367 ‑ 6372).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and atOccupant safety 41
Safety Z

regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The u restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the u restraint
system warning lamp: R
does not light up after the ignition is switched
on R
does not go out after a few seconds with the
engine running R
lights up again while the engine is running
G WARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer-
gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp C is
part of the Occupant Classification System
(OCS). The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp: R
is lit : the front-passenger front air bag is
deactivated. It will then not be deployed in the
event of an accident. R
is not lit : the front-passenger front air bag is
enabled. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey. R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" ( Y
page 49) and on "Chil-
dren in the vehicle" ( Y
page 58). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat. R
All other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated ( Y
page 49). Be sure to
observe the notes on "Seat
belts“ ( Y
page 42) and "Air bags"
( Y
page 46). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.42
