Lane departure warning performance tips

Several factors affect the performance of the lane departure warning system (LDWS). Some conditions may prevent the LDWS feature from detecting lane departures.

  • The LDWS feature provides alerts only when your vehicle speed exceeds 64 km/h (40 mph).

  • The LDWS feature does not provide alerts on certain types of roads, such as motorway slip roads or merging lanes.

  • The LDWS feature may not function properly if the camera is incorrectly aligned (Aligning the camera).

  • The LDWS feature may not function properly if the Camera placement option does not correctly indicate the placement of your device in the vehicle.

  • The LDWS feature requires a clear, continuous view of the lane divider lines.

    • Lane departures may not be detected when divider lines are obscured by rain, fog, snow, extreme shadows, sun or headlight glare, road construction, or any other visual obstruction.

    • Lane departures may not be detected if lane divider lines are misaligned, missing or heavily worn.

  • The LDWS feature may not detect lane departures on extremely wide, narrow or winding roads.
