When your vehicle is serviced, technical infor-
mation can be read from the event data memory and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
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:
Raccident reports
Rdamage to the vehicle
Rwitness 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:
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 theaccelerator and/or brake pedal and
RHow fast the vehicle was traveling
These data can help provide a better under-
standing of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a non-trivial crash situa-
tion occurs; no data are recorded by the EDR
under normal driving conditions and no personal
data (e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement could combine the EDR data
with the type of personally identifying data rou-
tinely acquired during a crash investigation.
Access to the vehicle and/or the EDR is needed
to read data that is recorded by an 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.

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, 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 raised
from the seat cushion
If it is absolutely necessary to install a child
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. a
cushion. Fully retract the seat cushion length.
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 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 a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation and operating
instructions.

tion (OCS)
:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp
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 position 1or 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 for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident.
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 PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion, an air bag
display message appears in the instrument clus-
ter (
Ypage 237). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front air bag both before and during the journey.

ProblemPossible causes/consequences andMSolutions
The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son of a stature corre-
sponding to that of an
adult.The classification of the person on the front-passenger seat is incor-
rect.
XMake sure the conditions for a correct classification of the person
on the front-passenger seat are met (Ypage 51).
XIf the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
XHave OCS checked as soon as possible at an authorized Mercedes- Benz Center.
The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seat
is:
Runoccupied
Roccupied with the
weight of a child up to
twelve months old in a
child restraint system
OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and the child
seat.
XMake sure that the entire base of the child restraint system rests on
the seat cushion of the 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. If necessary,
adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the child
restraint system. If necessary, adjust the head restraint accord-
ingly.
XMake sure that no objects are applying additional weight onto the
seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install a child restraint system on the front-passenger seat. It is recom-
mended that you install the child restraint system on a suitable rear
seat.
XHave OCS checked as soon as possible at an authorized Mercedes-Benz Center.
Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special-
ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of your
passenger to have deployed air bags replaced

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 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
as a result.
If the restraint system control unit detects a side
impact or if the vehicle rolls over, the applicable
components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
RSide impact air bags on the side where the
impact takes place, independently of the
Emergency Tensioning Device and the use of
the seat belt on the driver's seat and outer
seats in the second row
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
RWindow curtain air bag on the side of impact, independently of the use of the seat belt and
independently of whether the front-
passenger seat is occupied
RFront Emergency Tensioning Devices, if the
system determines that deployment can offer
additional protection for the vehicle occu-
pants in this situation
RRear Emergency Tensioning Devices in cer-
tain situations if the vehicle rolls over
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection 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:
RFrontal collision
RSide impact
RRollover
PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE®
takes pre-emptive measures to protect the vehi-
cle occupants.
Important safety notes
!Make sure that there are no objects in the
footwell or behind the seats. There is a danger
that the seats and/or objects could be dam-
aged when PRE-SAFE
®is activated.
Despite your vehicle being equipped with the
PRE-SAFE
®system, the possibility of personal
injuries occurring as a result of an accident can-
not be eliminated. Always adapt your driving
style to suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
Function
PRE-SAFE®intervenes:
Rin emergency braking situations, e.g. when
BAS is activated
Rin critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under-
steers or oversteers severely
Rvehicles with the Driving Assistance package:
when a driver assistance system intervenes
powerfully or the radar sensor system detects
an imminent danger of collision in certain sit- uations

surface. Pay particular attention to th einforma-
tion regarding tires ,recommended minimum
tire tread depths etc. in th e"Wheels and tires "
section (
Ypage 336).
In wintr ydriving conditions, always use winte r
tires (M+ Stires )and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 65).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 259) and dis-
play messages which may be shown in the
instrument cluster (
Ypage 228).
Braking
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extra care while driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 65).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
