Speed Limit Sign Recognition Indicator

Info
BYD · ADAS

This indicator illuminates when the Traffic Sign Recognition system detects a speed limit sign, displaying the current road speed limit. The system uses the front windscreen camera to identify roadside signs and remind you of speed restrictions. If the indicator fails to display, shows incorrect limits, or triggers false alerts, the camera may be obstructed, dirty, or the system may require servicing.

Yes — safe to drive

This light is a normal information prompt. If speed limits are frequently misread, clean the camera area located at the top of the windscreen. If abnormal operation persists, contact a BYD authorised service centre for camera calibration. Note: Speed limit recognition is for guidance only; always follow actual posted road signs.
