Operating safety
Important safety notes
WARNING
G
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 equipment when the vehicle is stationary.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximately
14 m) every second.
WARNING
G
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other networked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as
intended 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 electronic components or their software. You
should have all work to electrical and electronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle electronics, the general operating permit is rendered invalid.
!
Note: This equipment has been tested
and found to comply with the limits for a
Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed
to provide reasonable protection against
harmful interference when the equipment
is operated in a commercial environment.
This equipment generates, uses and can
radiate radio frequency energy and, if not
installed and used in accordance with the
instruction manual, may cause harmful
interference to radio communications.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). However, it is recommended to install
it at a distance of at least 8 inches (20 cm)
between the radiation source and a person's
body (not including limbs such as hands,
wrists, feet and legs).
Correct use
Always observe the following when using the
audio equipment:
R
the safety notes in this manual
R
national road traffic regulations
i
Using roof carriers may impair the correct
functioning of a roof antenna (phone, satellite radio, GPS).
Retrofitting metalized plastic films to the
windows can affect radio reception. It can
also lead to poorer reception of all other
antennas (e.g. emergency call antennas)
inside the vehicle.
i
Protection against theft: this device is
equipped with technical provisions to protect it against theft. Further information on
protection against theft can be obtained
from an authorized Mercedes-Benz Center.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
Introduction

ation is subject to the two following two conditions: 1) These devices may not cause
harmful interference, and 2) These devices
must accept any interference received,
including interference that may cause undesired operation. Changes or modifications not
expressly approved by the party responsible
for compliance could void the user’s authority
to operate the equipment."
Canada: "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 interference, and (2) These
devices must accept any interference, including interference that may cause undesired
operation of the device."
Audio system features
These Operating Instructions describe all
standard and optional equipment available
for your audio device at the time of going to
print. Country-specific differences are possible. Please note that your audio equipment
may not offer all the features described. This
also applies to safety-relevant systems and
functions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations.
The original purchase agreement lists all systems installed in your vehicle. Contact an
authorized Mercedes-Benz Center if you have
any questions about equipment or operation.
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
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or permanently store technical information about:
R
The vehicle's operating state
R
Incidents
R
Malfunctions
In general, this technical information documents the state of a component, a module, a
system or the surroundings.
These include, for example:
R
operating conditions of system components, e.g. fluid levels
R
the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelerator pedal position
R
malfunctions and defects in important system components, e.g. lights, brakes
R
vehicle reactions and operating conditions
in special driving situations, e.g. air bag
deployment, intervention of stability
control systems
R
ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
R
assist in recognizing and rectifying malfunctions and defects
R
analyze vehicle functions, e.g. after an accident
R
optimize vehicle function
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical information can be read from the event data memory and malfunction data memory.
Services include, for example:
R
repair services
R
service processes
Z
Introduction

R
warranties
R
quality assurance
It is read by employees of the service network
(including manufacturers) using special diagnostic devices. More detailed information is
obtained from it, if required.
After a malfunction has been rectified, the
information is deleted from the malfunction
memory or is continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if necessary, under consultation with an authorized
expert), could be traced to a person.
Examples include:
R
accident reports
R
damages to the vehicle
R
witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case
of an emergency.
