Official summary
Some customers may notice that the Lane Departure Warning System (LDWS) and High Beam Control (HBC) (amber) warning lights are on when they start driving around dusk or dawn under low temperatures. At that time, the windshield is clear but the lens of the Forward Sensing Camera (FSC) is foggy. The FSC may not function properly under the following conditions: ? Foggy windshield ? Foggy FSC lens ? Heavy rain, dense fog, snow and direct sun light ? No or poor lane markings. When the FSC control system detects the foggy lens of the camera, the system deactivates LDWS and HBC functions.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
