Turns up to fix a tyre puncture in vehicle (4)

I believe the answer is:

taxi

I'm a little stuck... Click here to teach me more about this clue!

'vehicle' is the definition.
(taxi is a kind of vehicle)

I don't understand how the rest of the clue works.

(Other definitions for taxi that I've seen before include "At airport, guide" , "Motor vehicle for hire with driver" , "Cab for hire" , "Danny DeVito sitcom" , "Prepare to take off" .)

I've seen this clue in The Irish Times.
