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

WARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop. G
WARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example:
R if the RF transmitter is not connected with
an exterior antenna
R the exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec-
tion exterior antenna.
! The operating permit may be invalidated if
the instructions for installation and use of RF
transmitters 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
0044 Rear roof area
0087 Rear fender
i 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. Vehicle electronics

The maximum transmission output (PEAK) at the
base of the antenna must not exceed the fol-
lowing values: Frequency band Maximum
transmission output Short wave

The following can be used in the vehicle without
restrictions:
R RF transmitters with a maximum transmis-
sion output of up to 100 mW
R RF transmitters with transmitter frequencies
in the 380 - 410 MHz frequency band and a
maximum transmission output of up to 2 W
(trunked radio system/Tetra)
R Mobile phones (2G/3G/4G)
There is no restriction for antenna positions on
the outside of the vehicle for the following fre-
quency bands:
