Notes on technical data  
This could jeopardize the operating safety of  
the vehicle.  
When operating two-way radios in the  
vehicle, always connect them to the  
low-reflection exterior antenna.  
Mercedes-AMG vehicles: be sure to observe  
the notes in the Supplement. Otherwise, you  
may fail to recognize dangers.  
Plug-in hybrid: be sure to observe the notes in  
the Supplement. Otherwise, you may fail to rec‐  
ognize dangers.  
The data stated only applies to vehicles with  
standard equipment. You can obtain further  
information from an authorized Mercedes-Benz  
Center.

You should have all work on electrical  
and electronic components carried out  
at a qualified specialist workshop.

WARNING Risk of accident from incor‐  
rect operation of two-way radios  
The operating permit may be invalidated if  
the instructions for installation and use of  
two-way radios are not observed.  
If you operate two-way radios incorrectly in  
the vehicle, the electromagnetic radiation  
could interfere with the on-board electronics,  
e.g.:

Only use approved frequency bands.  
Observe the maximum permissible out‐  
put power in these frequency bands.

Frequency band and maximum transmission  
output  
On the rear fenders, it is recommended that you  
install the antenna on the side of the vehicle  
closest to the center of the road.  
Use Technical Specification ISO/TS 21609 (Road  
Vehicles – "EMCs for installation of aftermarket  
radio frequency transmitting equipment") when  
retrofitting two-way radios. Comply with the  
legal requirements for detachable parts.  
If your vehicle has installations for two-way radio  
equipment, use the power supply and antenna  
connectors provided in the pre-installation. Be  
sure to observe the manufacturer's supplements  
when installing.
