24-GHz radar sensor system (country overview)
The 24 GHz radar sensor system requires separate approval for each country. If 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 203).
The current country overview can be obtained from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. Adisplay message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 222).
If Blind Spot Assist is active, it will be deactivated automatically (Y page 177).
If the deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 203).
