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

Always observe the following when using
Audio 20:
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.
10 Introduction

Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
iUSA only: The wireless devices of this
vehicle comply with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1) These devices may not cause interfer-
ence, and
2) These devices must accept any interfer-
ence, including interference that may
cause undesired operation of the device.
Changes or modifications not expressly
approved by the party responsible for com-
pliance could void the user's authority to
operate the equipment.
iCanada only: The wireless devices of this
vehicle comply with Industry Canada
license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1) These devices may not cause interfer-
ence, and
2) These devices must accept any interfer-
ence, including interference that may
cause undesired operation of the device.
Qualified specialist workshop
Read the information on qualified specialist
workshops in the vehicle Operator's Manual.
Function restrictions
For safety reasons, some functions are
restricted or unavailable while the vehicle is in
motion. You will notice this, for example,
because you will not be able to select certain
menu items.
Data stored in the vehicle
Data recording
This vehicle is capable of recording diagnostic
information relating to vehicle operation, mal-
functions, and user settings. This may include
information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake sys-
tems, that is stored and can be read out with
suitable devices, particularly when the vehi-
cle is serviced. The data obtained is used to
properly diagnose and service your vehicle or
to further optimize and develop vehicle func-
tions.
Audio 20/mbrace
If the vehicle is equipped with Audio 20 or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle may
be compiled through Audio 20 or the mbrace
system.
For additional information please refer to the
Audio 20 operating instructions and/or the
mbrace Terms and Conditions.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in under-
standing how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during air bag deployment or when
hitting a road obstacle. 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 are
operating
Rwhether or not the driver and passenger
seat belts are fastened
Introduction 11
Z

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-
ted. This means that in the event of such con-
flict, the federal regulation governs. As of
February 2013, 13 states have enacted laws
relating to EDRs.

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/LCD displays. Do not
apply pressure to the display surface when
cleaning it, as this could cause irreversible
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.
