For unlocking the airbag unit, a Phillips screwdriver (1), size 2, is required.
The shaft diameter must be 6 - 6.5 mm.
In order to avoid damage to the airbag, a maximum depth to which the screwdriver can be inserted into the disassembly opening must be marked on the screwdriver (1).
To do so, mark the dimension A on the screwdriver using insulating tape (2), for example.
Dimension A = 65 mm
First remove the right side of the airbag unit.
Turn the steering wheel (1) until the disassembly opening on the rear of the steering wheel is aligned to the steering column release lever.
Installation note:
Carefully push airbag unit in direction of steering column shaft into steering wheel with uniform pressing force until airbag engages noticeably and audibly.
Unlock the steering wheel release lever (1).
Align the Phillips screwdriver tangentially to the steering column axis and insert it into the disassembly opening without rotating it until the airbag unit is unlocked.
Do not exceed the earlier marked maximum insertion depth on the screwdriver.
