Using Dynamic Road Sign Display
Speed warning function
If the Dynamic Road Sign Display detects that an applicable speed limit has been exceeded, it can issue an acoustic
warning signal or display a message on the instrument cluster display.
You can set or completely deactivate the speed warning in the Assist systems menu in the Infotainment system
(→ Vehicle settings menu). The speed warning can be set to a value of 0 km/h(0 mph), 5 km/h (3 mph) or 10 km/h
(5 mph).
Trailer mode
In vehicles with a factory-fitted towing bracket and a trailer with an electrical connection to the vehicle, the display of
road signs that may apply to the vehicle when towing a trailer, e.g. applicable speed limits and no-overtaking signs,
can be activated or deactivated in the vehicle settings in the Infotainment system (→ Vehicle settings menu).
In trailer mode, the speed warning function display can be adjusted to the type of trailer or to legal requirements. The
settings can be adjusted in increments of 10 km/h (5 mph) within a range between 60 km/h (35 mph) and 130 km/h
(80 mph). If a higher speed is set than is permitted for driving with a trailer in the country in which you are currently
travelling, Dynamic Road Sign Display automatically issues a warning at the usual speed limit, e.g. at 80 km/h
(50 mph) in Germany.
