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 134). The current country
overview can be obtained from a Mercedes-
Benz Service Centre. The radar sensor system is automatically
deactivated near radio telescope facilities. If
Distronic Plus*, Blind Spot Assist* or PRE-
SAFE
®
Brake* are activated at this point, a
corresponding warning will appear in the
multi-function display to tell you that the
radar sensor system is being switched off.
BAS PLUS* is also no longer available. If the
deactivation does not occur automatically,
you must deactivate the radar sensor system
using the on-board computer (Y page 134).Country Radio telescope
