Road Sign Information with speed warning and settings*
The subfunction Speed Limit Warning for Road Sign Information (RSI[1]) is optional – the driver can choose to activate or deactivate this subfunction.
Speed Limit Warning warns the driver when the applicable speed limit or a preselected "top speed" is exceeded – this warning is repeated once after approx. 30 seconds within the same speed limit area unless the driver reduces the speed.
Another warning is available only when the driver has reduced the speed by at least 5 km/h (3 mph) and then exceeds the speed limit again, or when the car reaches a new/different speed limit area.

The speed warning is given by the driver display symbol[2] showing the applicable maximum permitted speed temporarily flashing when this speed is exceeded.

A speed warning is always given if the speed limit is exceeded in connection with speed camera information.
