ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor- mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec-
tion. Qualified specialist workshop
An authorized Mercedes-Benz Center is a quali-
fied specialist workshop. It has the necessary
specialist knowledge, tools and qualifications to correctly carry out the work required on your

nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, such as:
R Operating states of system components (e.g.
fill levels, battery status, tire pressure)
R Status messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi- cation of whether seat belts are fastened)
R Malfunctions and defects in important system
components (e.g. lights, brakes)
R Information about events leading to vehicle
damage
R System responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
R Ambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees (e.g. workshops, manufacturers) or
third parties (e.g. breakdown services). Services
can include repair services, maintenance pro-
cesses, warranty cases and quality assurance
measures. The data are read out via the con-
nection for the diagnostics connection in the
vehicle, which is required by law. The relevant
offices in the service network or third parties
collect, process and use the data. This data
documents the vehicle's technical states, is
used to help in finding malfunctions and improv-
ing quality and is sent to the manufacturer
where necessary. In addition, the manufacturer is subject to product liability. The manufacturerneeds technical data from vehicles for this pur-
pose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com- fort and infotainment functions yourself as part
of the selected equipment. These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to
the vehicle (e.g. smartphone, USB memory stick or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R General vehicle information
R Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of the app being used. Whether you can configure
settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem. Data stored in the vehicle

Online services
Wireless network connection If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi-
cle and other systems. The wireless network
connection is made possible by the vehicle's
own transmitter and receiver or by mobile devi- ces that you have brought into the vehicle (e.g.
smartphones). Online functions can be used via
this wireless network connection. These include online services and applications/apps providedby the manufacturer or other providers.
Services provided by the manufacturer In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place (e.g. operating instructions,
manufacturer's website) and provides the asso-
ciated information subject to data protection
legislation. Personal data can be used in order to
provide online services. The exchange of data
for this purpose takes place via a secure con-
nection, e.g. with the manufacturer's IT systems intended for the purpose. Collecting, processing
and using personal data beyond the provision of
services is permitted only on the basis of a stat-
utory permit or declaration of consent.
You can usually activate and deactivate the serv-
ices and functions (sometimes subject to a fee).
In many cases, this also applies to the vehicle's entire data connection. However, this does not
apply in particular to legally prescribed func-
tions and services such as the "eCall" emer-
gency call system.
Services from third parties If it is possible to use online services from other
providers, these services are the responsibility
of the provider in question and subject to that
provider's data protection conditions and terms of use. The manufacturer has no influence over
the content exchanged here.
For this reason, please ask the service provider
for information about the type, extent and pur-
pose of the collection and use of personal data
when services are provided by third parties. 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
USA only:
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
relating to vehicle dynamics and safety systemsfor 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 crashes
and injuries occur. NOTE:EDR data are recor-
ded by your vehicle only if a non-trivial crash
situation 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 routinely acquired during a crash investi-
gation.
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 34
Data stored in the vehicleIntroduction

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
the 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. This means that in the event of such conflict, the
federal regulation governs. As of February 2013, 13 states have enacted laws relating to EDRs. Information on copyright

seconds or once the driver's seat belt is fas-
tened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning
tone sounds. A warning tone also sounds with
increasing intensity for 60 seconds or until the
driver or front passenger have fastened their
seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt warn- ing is activated again. Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt.
When deployed, an air bag can increase the pro-
tection provided for the respective vehicle occu-
pant.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another (Y page 56).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
All vehicle occupants must observe the follow-
ing notes to avoid risks posed by the air bag
when it deploys.
R Adjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of the head restraint must support the head at
about eye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi- tion must allow the vehicle to be driven safely.
R Only hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
R Always lean against the backrest while driv-
ing. Do not lean forward or lean against the
door or side window. You may otherwise be in the deployment area of the air bags.
R Always keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
R For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under twelve years of
age and less than 5 ft (1.50 m)tall in suitable
child restraint systems.
R Child restraint systems should be installed on
the rear seats.
R Secure a child to the front-passenger seat
only when the front-passenger front air bag is
deactivated, and then only in a rearward-
facing child restraint system. The front-
passenger front air bag is deactivated when
the PASSENGER AIR BAG OFF indicator lamp
is lit continuously (Y page 45).
R Always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (Y page 51) and on "Children in the
vehicle" (Y page 59) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may restrict
the air bag from functioning correctly. To
avoid risks resulting from the speed of the air Occupant safety

Side impact air bags
G
WARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are designed to do. In addition, the operation of
the occupant classification system (OCS)
could be adversely affected. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz. Front side impact air bags
0043and second row
rear side impact air bags 0044deploy next to the
outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. It also offers addi-
tional pelvis protection for occupants in the
front seats. However, it does not protect the:
R head
R neck
R arms
If the restraint system control unit detects a side
impact, the side impact air bag is deployed on
the side on which the impact occurs.
The side impact air bag on the front passenger
side deploys under the following conditions:
R the OCS system detects that the front
passenger seat is occupied or
R the seat belt buckle tongue is engaged in the
belt buckle of the front passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent of whether the front passenger seat is occupied
or not.
Window curtain air bags Window curtain air bags
0043are integrated into
the side of the roof frame and deploy in the area
extending from the front door (A-pillar) to the
rear side window (D-pillar).
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
If the restraint system control unit detects a side
impact, the window curtain air bag is deployed
on the side on which the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(Y page 56). 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:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices Occupant safety
