Operating safety
General information
GWARNING
To avoid distractions that could lead to an
accident, you should only change system
settings when the vehicle is stationary and
operate the system only when road, weather,
and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle covers
a distance of 44 feet (approximately 14 m)
every second.
For safety reasons, we recommend that you
stop the vehicle in accordance with traffic
conditions before answering or placing a call
or before consulting the Audio 20 screen to
read instructions or downloaded information.
iCanada only: This device complies with
RSS-210 of Industry Canada. Operation is
subject to the following two conditions:
1. This device may not cause interference,
and
2. this device must accept any interference
received, including interference that may
cause undesired operation of the device.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment.
iUSA only: This device complies with Part
15 of the FCC Rules. Operation is subject
to the following two conditions:
1. This device may not cause interference,
and
2. this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment.
GWARNING
Change or modification not expressly
approved by the party responsible for
compliance could void the user's authority to
operate this equipment.
! 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.
GWARNING
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). But it is desirable that it should be
installed and operated with at least 8 inches
(20 cm) 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 the
audio equipment:
Rthe safety notes in this manual
Rall road traffic regulations
GWARNING
Modifications made to electronic
components or software can cause
malfunctions.
The radio, satellite radio, amplifier, CD
changer and telephone are interlinked. If one
component is not functional or if it has been
Introduction 7
Z

incorrectly removed/replaced, this could
impair the operation of other components.
This could seriously jeopardize the
operational safety of your vehicle.
We recommend that you always have
maintenance work on electronic components
carried out at an authorized Mercedes-Benz
Center.
iRoof antenna functionality (telephone,
satellite radio, GPS) can be affected by the
use of roof carrier systems.
Retrofitting metalized plastic films to the
windows can affect radio reception and
lead to poorer reception of all other
antennas (e.g. emergency call antennas)
inside the vehicle.
iProtection 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.
! Electronic devices that you bring into the
vehicle yourself can cause significant
problems with the radio reception.
Audio device features
These Operating Instructions describe all
standard and optional equipment available
for your audio device at the time of going to
print. Country-specific deviations are
possible. Please note that your audio
equipment may not offer all the features
described. This includes safety-related
systems and functions. The equipment in
your vehicle may therefore differ from some
of the descriptions or 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 Audio 20 functions
are restricted or unavailable while the vehicle
is in motion. You will notice this, for example,
because you will either not be able to select
certain menu items or because Audio 20 will
display a message to that effect.
