# Service bulletin 15\-003\-17\-3284b

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10120386
- Published by NHTSA: 2017\-10\-21
- Manufacturer's number: 15\-003\-17\-3284b
- Manufacturer's date: 2017\-09\-08
- NHTSA component: EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS; LANE DEPARTURE: WARNING

## NHTSA's 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.
