Operating safety
Important safety notes
G
WARNING
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 just 30 mph
(approximately 50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second. G
WARNING
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
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 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.
! 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 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). 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, sat-
ellite 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 pro-
tect it against theft. Further information on
protection against theft can be obtained
from an authorized Mercedes-Benz Center. Declarations of conformity
