•
poor weather with reduced visibility
•
roads with unclear or non-existent side mark-
•
ings
sharp edges or lines other than the lane's
•
side markings

reduced power – e.g. when cooling due to
overheating.
The function is unable to detect barriers, rails or
similar obstacles at the side of the carriageway.
