Event data recorders
USA only:
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped withan event data recorder (EDR). The main pur-pose of an EDR is to record, in certain crash ornear crash-like situations, such as an air bagdeployment or hitting a road obstacle, datathat will assist in understanding how a vehi-cle's systems performed. The EDR is designedto record data related to vehicle dynamics andsafety systems for a short period of time, typi-cally 30 seconds or less.
The EDR in this vehicle is designed to recordsuch data as:
RHow various systems in your vehicle wereoperating
RWhether or not the driver and passengersafety belts were buckled/fastened
RHow far (if at all) the driver was depressingthe accelerator and/or brake pedal; and,
RHow fast the vehicle was traveling
These data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR dataare recorded by your vehicle only if a non-triv-ial crash situation occurs; no data are recor-ded by the EDR under normal driving condi-tions and no personal data (e.g. name, gender,age and crash location) are recorded. How-ever, other parties, such as law enforcementcould combine the EDR data with the type ofpersonally identifying data routinely acquiredduring a crash investigation.
Access to the vehicle and/or the EDR is nee-ded to read data that is recorded by an EDR,and special equipment is required. In addition

Restraint system warning lamp
The functions of the restraint system arechecked after the ignition is switched on andat regular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.
Theurestraint system warning lamp onthe instrument cluster lights up when the igni-tion is switched on. It goes out no later than afew seconds after the vehicle is started. Thecomponents of the restraint system are inoperational readiness.
A malfunction has occurred if theurestraint system warning lamp:
Rdoes not light up after the ignition isswitched on
Rdoes not go out after a few seconds with theengine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. 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 indicator lamp
PASSENGER AIR BAG ON indicator lampCand PASSENGER AIR BAG OFF indicatorlampDare part of the Occupant Classifica-tion System (OCS).
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60seconds, subsequently both indicator lampsare off (PASSENGER AIR BAG ON and OFF):the front-passenger front air bag is able todeploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must either be deactivated or enabled;see the following points. You must make sureof this both before and during a journey.
RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on theinstalled child restraint system, and the ageand size of the child. Therefore, be sure toobserve the notes on the "Occupant Classifi-cation System (OCS)" (Ypage 46) and on"Children in the vehicle" (Ypage 53).There you will also find instructions on rear-ward and forward-facing child restraint sys-tems on the front-passenger seat.
RAll other persons:depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag isenabled or deactivated (Ypage 46). Besure to observe the notes on "Seatbelts“ (Ypage 39) and "Air bags"(Ypage 43). There you can also find infor-mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle roll-ing over. This reduces the risk of vehicle occu-pants coming into contact with parts of thevehicle interior or being ejected from the vehi-cle. Furthermore, the seat belt helps to keep

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe headbag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If you install a child restraint system on thefront-passenger seat, be sure to observe thecorrect positioning of the child restraint sys-tem. Never place objects under or behind thechild restraint system, e.g. a cushion. Theentire base of the child restraint system mustalways rest on the seat cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat aspossible against the backrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.

XPress the Start/Stop button once or twice,or turn the SmartKey to positionGorHinthe ignition lock.The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps mustlight up simultaneously for approximately sixseconds.
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for60 seconds, subsequently both indicatorlamps are off (PASSENGER AIR BAG ON andOFF): the front-passenger front air bag isable to deploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag display message appears in the instru-ment cluster (Ypage 191). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG OFF indicatorlamp. Be aware of the status of the front-
46Occupant safety
Safety

passenger front air bag both before and duringthe journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag
is disabled. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for exam-
ple, come into contact with the vehicle's
interior, especially if the 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
disabled in accordance with the person in
the front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR
BAG OFF indicator lamp is off, the front-
passenger front air bag can deploy in the
event of an accident. The child could be
struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT
AIRBAG in front of it; DEATH or SERIOUS
INJURY to the child can occur.
If the PASSENGER AIR BAG OFF indicator lampstays off, do not install a rearward-facing child
restraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant ClassificationSystem" (Ypage 49).
GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat
too close to the dashboard, in the event of
an accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the
PASSENGER AIR BAG OFF indicator lamp
is off
This poses an increased risk of injury or
even fatal injury.
Move the front-passenger seat as far back
as possible. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt guide to the shoulder belt
guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt guide.
Always observe the child restraint system
manufacturer's installation instructions.
If OCS determines that:
RThe front-passenger seat is unoccupied, thePASSENGER AIR BAG OFF indicator lamplights up after the self-test and remains lit.This indicates that the front-passenger frontair bag is deactivated.
RThe front-passenger seat is occupied by achild of up to twelve months old, in a stand-ard child restraint system, the PASSENGERAIR BAG OFF indicator lamp lights up afterthe self-test and remains lit. This indicatesthat the front-passenger front air bag isdeactivated.
But even in the case of a twelve-month-oldchild, in a standard child restraint system,the PASSENGER AIR BAG OFF indicatorlamp can go out after the self-test. This indi-cates that the front-passenger front air bagis activated. The result of the classificationis dependent on, among other factors, thechild restraint system and the child's stat-

ure. Make sure that the conditions for a cor-rect classification are met. If thePASSENGER AIR BAG OFF indicator lampremains off, do not install a child restraintsystem on the front-passenger seat.
RThe front-passenger seat is occupied by aperson of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp either lights up and remainslit after the self-test depending on the resultof the classification or, alternatively, goesout.
-If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seatas far back as possible.
-If the PASSENGER AIR BAG OFF indicatorlamp is lit, a person of smaller statureshould not use the front-passenger seat.
RThe front-passenger seat is occupied by anadult or a person of corresponding stature,the PASSENGER AIR BAG OFF indicatorlamp goes out after the self-test. This indi-cates that the front-passenger front air bagis activated.
If children are traveling in the vehicle, be sureto observe the notes on "Children in the vehi-cle" (Ypage 53).
When the Occupant Classification System(OCS) is malfunctioning, the redurestraintsystem warning lamp on the instrument clus-ter and the PASSENGER AIR BAG OFF indica-tor lamp light up simultaneously. The front-passenger front air bag is deactivated in thiscase and does not deploy during an accident.Have the Occupant Classification System(OCS) checked and repaired immediately at aqualified specialist workshop. Mercedes-Benzrecommends that you use an authorizedMercedes-Benz Center for this purpose.
If the front-passenger seat, the seat cover orthe seat cushion are damaged, have the nec-essary repair work carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose.
For safety reasons, Mercedes-Benz recom-mends that you only use seat accessories thathave been approved by Mercedes-Benz.
Deployment of the driver's air bag does notmean that the front-passenger front air bagdeploys as well. The Occupant ClassificationSystem (OCS) categorizes the occupant on thefront-passenger seat. Depending on that
result, the front-passenger front air bag iseither enabled or deactivated.
Self-check of the Occupant Classifica-
tion System (OCS)
GDANGER
If the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not both light up during the 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
deceleration. 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 a child restraint
system on the front-passenger seat. Have
the Occupant Classification System (OCS)
checked and repaired immediately at a
qualified specialist workshop.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the self-test, the front-
passenger front air bag is deactivated. 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
function, e.g. when a person 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
48Occupant safety
Safety

deactivated in accordance with the per-
son in the front-passenger seat
Rthe person is seated properly with a cor-
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 must not be used. Do
not install a child restraint system on the
front-passenger seat. Have the Occupant
Classification System (OCS) checked and
repaired immediately at a qualified specialist
workshop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS
operation. This could result in the front-
passenger air bag not functioning as inten-
ded 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, be resting on the back-
rest of the front-passenger seat. Always
comply with the child restraint system man-
ufacturer's installation instructions.
After the self-test, the PASSENGER AIR BAGOFF or the PASSENGER AIR BAG ON indicatorlamp displays the status of the front-passenger front airbag (Ypage 46). If thefront-passenger front airbag is enabled, thePASSENGER AIR BAG ON indicator lamp lightsup for 60 seconds and then goes out.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front airbag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
For more information about the OCS, see"Problems with the Occupant ClassificationSystem" (Ypage 49).
