Operating safety
Important safety notes
GWARNING
If you operate integrated communication
equipment in the vehicle when driving, you
will be distracted from traffic conditions. You
could also lose control of the vehicle. There is
a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h) your vehicle covers
a distance of 44 feet (approximately 14 m)
per second.
GWARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supple-
ment C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). But it is desirable that it should be
installed and operated with at least 8inches
(20cm) and more between the radiator and a
person's body (excluding extremities: hands,
wrists, feet and legs.)
Correct use

Rthe safety notes in this manual
Rtraffic rules and regulations
Rlaws and safety standards pertaining to
motor vehicles
Roof antenna functionality (telephone, satel-
lite radio, GPS) can be affected by the use of
roof carrier systems.
Attaching metalized retrofit film to the wind-
shield may affect radio reception and have a
negative impact on all other antennas (e.g.
emergency antenna) in the vehicle interior.
Protection against theft: this device is
equipped with technical provisions to protect
it against theft. Further information on pro-
tection against theft can be obtained from an
authorized Mercedes-Benz Center.

Datastored in thevehicle
Datarecording
Thisvehicle is capable of recordingdiagnostic
information relatingto vehicle operation,mal-
functions, and user settings. Thismay include
information about theperformanceor status
of various systems,includingbut notlimited
to,engine, throttle, steeringor brake sys-
tems,that is stored and can be readout with
suitable devices, particularly when thevehi-
cleis serviced. The dataobtained is used to
properly diagnose and serviceyour vehicle or
to further optimize and develop vehicle func-
tions.
Audio 20/mbrace
If thevehicle is equipped withAudio 20 or
mbrace,additional dataabout thevehicle’s
operation,theuse of thevehicle in certain
situations, and thelocation of thevehicle may
be compiled through Audio 20 or thembrace
system.
Foradditional information pleaserefer to the
Audio 20 operatinginstructionsand/orthe
mbrace Terms and Conditions.
Eventdata recorders
Thisvehicle is equipped withan event data
recorder (EDR).The main purposeof an EDR
is to recorddatathat will assist in under-
standinghow avehicle’s systems performed
in certain crash or near crash-likesituations,
suchas duringair bag deploymentor when
hitting aroad obstacle. The EDRis designed
to recorddatarelated to vehicle dynamics
and safetysystems for a short period of time,
typically 30 seconds or less.
The EDRin this vehicle is designed to record
suchdataas:
Rhow various systems in your vehicle are
operating
Rwhether or notthedriver and passenger
seat beltsare fastened
12 Introduction

Rhow far (if at all) the driver is depressing the
accelerator and/or brake pedal and
Rhow fast the vehicle is traveling
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur. NOTE: EDR data is
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
crash location) are recorded. However, other
parties, such as law enforcement, can com-
bine the EDR data with the type of personal
identification data routinely acquired during a
crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehi-
cle or the EDR is needed. 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
matters as a tool in accident reconstruction,
accident 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 lia-
bility arising from the extraction of this infor-
mation by unauthorized Mercedes-Benz per-
sonnel.
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
enforcement; by federal, state or local gov-
ernment; in connection with or arising out of
litigation involving MBUSA or its subsidiaries
and affiliates; or, as required by law.
Warning: The EDR is a component of the Sup-
plemental Restraint System ("SRS") Module.
Tampering with, altering, modifying or remov-
ing the EDR component may result in a mal-
function of the SRS Module and other sys-
tems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-emp-

which could be irreversible.

Cleaning instructions
!Do not touch the display. The display has
a very sensitive high-gloss surface; there is
a risk of scratching. If you have to clean the
screen, however, use a mild cleaning agent
and a soft, lint-free cloth.
The display must be switched off and have
cooled down before you start cleaning. Clean
the display screen, when necessary, with a
commercially available microfiber cloth and
cleaning agent for TFT and LCD displays. Do
not apply pressure to the display surface
when cleaning it, as this could cause irrever-
sible damage to the display. Then, dry the
surface with a dry microfiber cloth.
Avoid using alcoholic thinners, gasoline or
abrasive cleaning agents. These could dam-
age the display surface.
