Even tdata recorders
Thi svehicl eise quipped with an event data

event data recorde r(EDR). The mai npurpose of
an EDR is to record, in certain cras hornear
crash-like situations, such as an ai rbag deploy-
ment or hitting aroado bstacle, data that will
assis tinunderstanding how avehicle's systems performed. The EDR is designed to record data
relate
dtovehicledynamics and safety systems
for ashort perio doftime,typicall y30seconds
or less.
The EDR in this vehicl eisdesigned to record
such data as:
RHow various systems in your vehicl ewere
operating
RWhether or not the driver and passenger
safety belts were buckled/fastened
RHow far (i fatall)t he driver wa sdepressing the
accelerato rand/or brake pedal and
RHow fas tthe vehicl ewastraveling.
These data can hel pprovid eabetterunder-
standing of the circumstances in which acci-
dents and injurie soccur. NOTE: EDR data are
recorde dbyyourv ehicl eonly if anon-trivial
cras hsituation occurs; no data is recorde dby
the EDR under normald riving conditions and no
personald ata(e.g. name ,gender, ag eand acci-
dent location) are recorded. However, othe rpar-
ties ,suc hasl awenforcement could combine
EDR data with the typ eofpersonal
l
yide ntifying
data routinel yacquired during acras hinvesti-
gation.
Access to the vehicl eand/or the EDR is needed
to rea ddatat hat is recorde dbythe EDR, and
specia lequipment is required .Inaddition to the
vehicl emanufacturer, othe rpartie sthat have
the specia lequipment, such as la wenforce-
ment, can rea dthe information by accessing the
vehicl eorthe EDR.
EDR data may be used in civi land crimina lmat-
ters as atool in accident reconstruction, acci-
dent claims and vehicl esafety .Since the Crash
Data Retrieval CDR tool that is used to extract
data from the EDR is commerciall yavailable,
Mercedes-Benz USA, LLC ("MBUSA")e xpressly
disclaims any and al lliabili ty arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share EDR data with others
withou tthe consent of the vehicl eowners or, if

The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: 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.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the status of the front-passenger front air bag changes while the vehicle is in motion,ana ir bag
display message appears in the instrument clus-
ter (
Ypage 229). When the front-passenger
seat is occupied, alwaysp ay 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. It will not 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-
cially if the person is sittin gtoo close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
alwayse nsure that:
Rthe classification of the person in the front-
passenger seat is correcta nd the front-
passenger front air bag is enabled or disa-
bled in accordanc ewith 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 achild in arearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag may deploy in 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 disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install arear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" (
Ypage 53).
GWARNING
If you secure achild in aforward-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 ON is lit up
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retrac tthe seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash guide to the shoulder

GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenge rfront air bag is disabled. It will
not be deploye dinthe event of an accident. In
this case, the front-passenge rfront air bag
cannot perform its intended protective func-
tion, e.g. when apersoniss eated in the front-
passenger seat.
That personc ould, for example, come into
contact with the vehicle's interior, especially
if the personiss itting too close to the dash-
board. This poses an increased risk of injury or
even fatal injury.
When the front-passenge rseat is occupied,
alway sensure that:
Rthe classification of the personint he front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bledina ccordance with the personint he
front-passenge rseat
Rthe personiss eated properly with acor-
rectly fastened seatbelt
Rthe front-passenge rseat 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 .Donot
instal lachild restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediatel yataqualified specialist work-
shop.
GWARNING
Objects between the seat surface and the
child restraint system coul daffect OCS oper-
ation. This coul dresult in the front-passenger
air bag not functioning as intended during an
accident. This posesani ncreased 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
alway srest 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-passenge rseat. 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
lamp display sthe status of the front-passenger
