The yellow light functions as the electronic steering damper warning indicator.
The light and warning symbol "ESD" go on if there is a malfunction in the electronic steering damper system.
However, this could also be caused by trouble with the charging system (e.g.
battery). If the warning light comes on, check the battery to be sure it is fully charged. If the battery is fully charged and the warning light still goes on, have the electronic steering damper system checked by an authorized Kawasaki dealer.
The electronic steering damper system maintains the last damping force setting if it fails.
