Always pay attention to road and driving conditions, while driving.

BCW and BCA may not operate properly when driving on a curved road. In certain instances the system may recognize a vehicle in the same lane.

Always pay attention to road and driving conditions, while driving.

• Driving where the road is merging/ dividing

Always pay attention to road and driving conditions, while driving.

• Driving on a slope

BCW and BCA may not operate properly when driving on a slope. In certain instances the system may not detect the vehicle in the next lane.

Also, in certain instances the system may wrongly recognize the ground or structures.

Always pay attention to road and driving conditions, while driving.

• Driving where the heights of the lanes are different

BCW and BCA may not operate properly when driving where the heights of the lanes are different.

In certain instances, the system may not detect the vehicle on a road with different lane heights (underpass joining section, grade separated intersections, etc.).

Always pay attention to road and driving conditions, while driving.

[A] : noise barrier, [B] : guardrail

• Driving where there is a structure beside the road

BCW and BCA may not operate properly when driving where there is structure beside the road.

In certain instances, the system may wrongly recognize the structures (noise barriers, guardrail, double guardrail, median strip, bollard, street light, road sign, tunnel wall, etc.) beside the road.
