Before operating the handlebars of the Opel Corsa D, you need to turn in the straight-ahead position. From the central part of the steering wheel there is a need to remove the airbag, which is behind the grey bar. The panel is held in latches and can be removed by a screwdriver or other suitable instrument. Then gently pull the bezel on you, remove and disconnect the wire from the beeper button. The centre of the steering wheel, behind the airbag, has a bolt that needs to be weakened. This will require a hexagonal key. The bolt out, the rudder, needs to pull it off to take it off.
