Sign Assist is always offered in combination with a navigation system as the traffic signs are also indicated on the display of the active navigation system (map and/or pictograms). If the front camera detects speed limits or no overtaking signs, up to three of these signs are indicated on the multi-function display ahead of the driver and on the navigation system. The navigation system displays the signs in a logical sequence together with all relevant additional information. The operative traffic sign (e.g. “130 km/h”) is always shown first, followed by signs which apply under certain conditions on a temporary basis (e.g. “80 km/h” “in wet conditions”) in second place. If the rain sensor detects precipitation, the operative traffic sign with the additional information “in wet conditions” is shown in first place.
