24 GHz radar sensor system (country overview)
The 24 GHz radar sensor system requires separate approval for each country. When you are
driving in a country in which the radar sensor system is not approved, you must deactivate
the system using the on-board computer (Y page 242).
The current country overview can be obtained from a Mercedes-Benz Service Centre or on
the Internet at: http://www.mercedes-benz.de/betriebsanleitung.
Vehicles with a navigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. A display message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 272).
The currently active systems are automatically deactivated:

R Blind Spot Assist (Y page 203)
R Active Blind Spot Assist (Y page 207)

If deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 242).

sensor system using the on-board computer when you are near a radio telescope facility
