  2. Disconnection of the battery ground terminal
    1. Turn the ignition switch to OFF, disconnect the battery ground terminal, and then wait for 60 seconds before starting the work. (Refer to WORKING PRECAUTIONS AND NOTES )
      WARNING: The air bag and pretensioner system are fitted with a backup power supply. If you start the work within 60 seconds after disconnecting the battery ground terminal, the air bag may be activated.
