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 65 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.
• The LDWS feature may not function properly if the camera placement settings do not correctly indicate your
vehicle height or 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.
