In certain instances, the function may not detect the vehicle on a road with different lane heights (i.e. underpass joining section, grade separated intersections, etc.).
Always pay attention to road and driving conditions, while driving.
-
Driving where there is a structure beside the road

[A] : noise barrier, [B] : guardrail
The function may not operate properly when driving where there is structure beside the road.
