- Make sure the torsion bar - 2 - is seated in the mounting bracket - arrow - on the seat pan - 1 - correctly.
- Prevent the bracket from spreading using (2024 A /1) and the M10 x 30 bolt - 3 - and nut.
- Mount the (3145) and bracket (2024 A /1) to the torsion bar - 1 -.
2 Seat pan
- Carefully rotate the torsion bar - 1 - until it engages in the oblong hole - arrow - on the seat pan - 2 -.
Further installation is performed in reverse sequence of removal, but observe the following:
• Follow all safety precautions when working on pyrotechnic components.
• Before handling pyrotechnic components (for example, connecting electrical connector), the person handling them must discharge static electricity. For example, by briefly touching the door striker pin.
• Make sure the connectors are installed all the way in and are secure.
Connect the battery with the ignition switched on. Pyrotechnic components could deploy after connecting the battery if they were not repaired correctly. Individuals must not be inside the vehicle when connecting the battery.
- Connect the battery ground cable with the ignition turned on.
• If the airbag indicator lamp (K75) indicates a fault after installation, the DTC memory must be checked, deleted and checked again using the Vehicle diagnostic tester.
