The speed limit information provided by the navigation map data could be inaccurate or out of date.
The system may not detect and read speed limit signs with conditional information, for example, when a sign is flashing, during specific time ranges, or when children are present.
Note:   The system does not set the vehicle speed to speed limits shown with a supplementary traffic sign.
Under certain conditions, the system may not adjust the vehicle speed until after your vehicle passes the speed limit.
