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 highway ramps 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.
