Information regarding technical data
i
The data stated here specifically refers to a
vehicle with standard equipment. Consult an
authorized Mercedes-Benz Center for the
data for all vehicle variants and trim levels.
Vehicle electronics
Installing two-way radios and mobile
phones (RF transmitters)
G
WARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle electron-
ics if two-way radios are manipulated or ret-
rofitted incorrectly. This could jeopardize the
operating safety of the vehicle. There is a risk
of an accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop.
G
WARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics, for
example if:
R
the two-way radio is not connected to an
exterior antenna
R
the exterior antenna is not correctly moun-
ted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating in
the vehicle.
!
The operating permit may be invalidated if
the instructions for installation and use of
two-way radios are not observed.
In particular, the following conditions must be
complied with:
R
only approved wavebands may be used
R
observe the maximum permissible output
in these wavebands
R
only approved antenna positions may be
used
Excessive levels of electromagnetic radiation
may cause damage to your health and the health
of others. Using an exterior antenna takes into
account current scientific discussions relating
to the possible health hazards that may result
from electromagnetic fields.
Approved antenna positions
:
Front roof area
;
Rear roof area
=
Rear fender
?
Trunk lid
i
On vehicles with panorama roof with power
tilt/sliding panel, installing an antenna to the
front or rear roof area is not permitted.
On the rear fenders, it is recommended to
position the antenna on the side of the vehicle
closest to the center of the road.
Use the Technical Specification ISO/TS 21609
when retrofitting RF transmitters (Road Vehicles
- EMC guidelines for installation of aftermarket
radio frequency transmitting equipment).
Observe the legal requirements for accessory
parts.
If your vehicle has installations for two-way radio
equipment, use the power supply or antenna
connections intended for use with the basic wir-
ing. Be sure to observe the manufacturer's Sup-
plement when installing.
Deviations with respect to frequency bands,
maximum transmission outputs or antenna
positions must be approved by Mercedes-Benz.
