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 223).
The current country overview can be obtained from a Mercedes-Benz Service Centre or on
the Internet at:

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 246).
If Blind Spot Assist is active, it will be deactivated automatically (Y page 219).
If deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 223).
Vehicles without navigation and vehicles for Australia: you must deactivate the radar
sensor system using the on-board computer when you are near a radio telescope facility
