Further installation is performed in reverse sequence of removal, but observe the following:
• Follow the safety precautions for pyrotechnic components. Refer to => [ Restraint System Components ] Description and Operation.
• Before handling pyrotechnical components (for example, connecting electrical connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.
• Ensure that electrical connections are pushed in as far as stop and engage with a click.
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.
