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.
The speed warning can be set or completely deactivated in the vehicle settings in the
Infotainment system (→ Vehicle settings menu, Operation). The settings can be adjusted in
increments of 5 km/h (3 mph) within a range between 0 km/h (mph) and 15 km/h (9 mph) above
the permitted maximum speed.
Function limitations
Dynamic Road Sign Display is subject to system-related limitations. The following conditions can
restrict the function of Dynamic Road Sign Display, or prevent it from working altogether:
—Poor visibility, e.g. due to snow, rain, fog or heavy spray.
—Glare, e.g. from oncoming traffic or sunlight.
—High speeds.
—A covered or dirty camera.
—Road signs located outside of the camera's field of view.
—Partially or fully hidden road signs, e.g. by trees, snow, dirt or other vehicles.
—Non-standard road signs.
—Damaged or bent road signs.
—Variable road signs on gantries (changeable road sign display using LEDs or other light
sources).
—Out-of-date map material in the Infotainment system.
—Vehicles with road sign stickers, e.g. speed restrictions on trucks.
WARNING
The intelligent road sign recognition system technology cannot overcome the laws of physics,
and functions only within the limits of the system. Do not let the extra convenience afforded by
Dynamic Road Sign Display tempt you into taking any risks when driving. The system is not a
substitute for the full concentration of the driver.

●
Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
Poor visibility, darkness, snow, rain and fog can cause traffic signs to be not displayed or be
incorrectly displayed by the system.
If the camera's field of view is dirty, covered or damaged, the function of the Dynamic Road
Sign Display system may be impaired.
WARNING
Driving recommendations and traffic symbols displayed by the Dynamic Road Sign Display
system may differ from the current traffic situation.
●
Not all road signs can be recognised by the system and displayed correctly.
●
Road signs on the road and traffic regulations have priority over the recommendations and
displays provided by the Dynamic Road Sign Display system.
NOTICE
Availability of the Dynamic Road Sign Display function is limited in waypoint mode (waypoint
navigation) of the Infotainment system.
Some settings can be saved in the user accounts of the personalisation function and can
therefore change automatically when the user account is changed (→ Personalisation,
Description).
