Steered (6)
I believe the answer is:
guided
'steered' is the definition.
('guide' can be a synonym of 'steer')
This is the entire clue.
(Other definitions for guided that I've seen before include "Directed the course of, 24 dn say" , "Directed or steered" , "Showed the way, lead" , "Showed the way, led" , "Directed as missile might be" .)
