drawing is reached. If the trunk lid panel height on one side is 
different from that on the other side (even after the trunk lid 
dampers have been adjusted to the height indicated in the 
drawing), turn the trunk lid damper(s) slightly to make fine 
adjustments to the trunk lid panel height.

NOTE: When the damper is new, one full turn of the trunk lid 
damper changes the height approximately 3 mm. Turn it clock-
wise to reduce height. Turn it counterclockwise to increase 
height.
