Seat Belt System: General Description: Precautions

Before starting, turn the ignition switch to OFF, disconnect the battery ground cable and wait for 20 seconds or more.
The pretensioner system has a backup power source. The pretensioner might deploy if you do not wait for 20 seconds or more before starting work.
Do not drop or apply any impact to the pretensioner.
If oil, grease, or water gets on the pretensioner, wipe it off immediately with a dry cloth.
Do not expose the pretensioner to high temperature or flame.
Do not allow current to flow through or voltage to reach the pretensioner. Do not use a circuit tester to check resistance of the pretensioner.
Do not disassemble or attempt to repair the pretensioner. If it is dented, cracked, or deformed, replace it with a new one.
Do not use the airbag or pretensioner parts from other vehicles. Always replace parts with new parts.
When handling a seat belt with a deployed pretensioner, wear gloves and goggles. Wash your hands afterwards.
Do not re-use a seat belt with a deployed pretensioner again.
If the material gets in your eyes or on your skin during deployment, wash it away with clean water, and then consult a doctor.
