Perform remaining installation steps in reverse order of removal; observe the following:   WARNING t  Observe safety regulations for pyrotechnic components → Chapter. t  Before handling pyrotechnic components (e.g. plugging in the electrical connector) the mechanic must discharge static electricity by briefly touching the door striker plate, or similar.   Note Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.   WARNING The battery must be connected with the ignition switched on. If pyrotechnic components (e.g. airbag or belt tensioner) are inexpertly repaired, this may result in unwanted triggering after connecting the battery. There must not be anyone in the vehicle while you are connecting the battery. –  With ignition switched on, connect battery earth wire → Electrical system; Rep. gr.27.   Note If the airbag warning lamp -K75- indicates a fault following installation, you must interrogate, erase and then re-interrogate the event memory → Vehicle diagnostic tester.
