FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND FRONT SEAT OUTER BELT ASSEMBLY WITH PRETENSIONER
The FJ CRUISER is equipped with a Supplemental Restraint System (SRS).

CAUTION: Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing and lead to serious injury. Furthermore, if a mistake is made when servicing the SRS, it is possible that the SRS may fail to operate properly. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following information carefully.
1. GENERAL NOTICE
  1. As malfunctions of the SRS are difficult to confirm, the Diagnostic Trouble Codes (DTCs) become the most important source of information when troubleshooting. When troubleshooting the SRS, always check the DTCs before disconnecting the battery.
  2. Work must be started at least 90 seconds after the ignition switch is turned OFF and after the cable is disconnected from the negative (-) battery terminal.
    (The SRS is equipped with a backup power source. If work is started within 90 seconds after turning the ignition switch OFF and disconnecting the cable from the negative (-) battery terminal, the SRS may deploy. When the cable is disconnected from the negative (-) battery terminal, clock and audio system memory is erased. Before starting work, make a note of the settings of each memory system. When work is finished, reset the clock and audio system as before.
    
    CAUTION: Never use a backup power source (battery or other) to avoid erasing system memory. The backup power source may inadvertently power the SRS and cause it to deploy.
  3. Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, front seat side airbag assembly, curtain shield airbag assembly and seat belt pretensioner should be inspected
  4. In minor collisions where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, front seat side airbag assembly, curtain shield airbag assembly and seat belt pretensioner should be inspected before further use of the vehicle.
  5. Never use SRS parts from another vehicle. When replacing parts, use new parts.
  6. Before repairs, remove the airbag sensor assemblies if impacts are likely to be applied to the sensor during repairs.
  7. Never disassemble and attempt to repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly and seat belt pretensioner.
  8. Replace the steering wheel pad, front passenger airbag assembly, front seat side airbag assembly, curtain shield airbag assembly and seat belt pretensioner if: 1) damage has occurred from being dropped, or 2) cracks, dents or other defects in the case, bracket or connector are present.
  9. Do not directly expose the airbag sensor assemblies or airbag assemblies to hot air or flames.
  10. Use an ohmmeter / voltmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits.
  11. Information labels are attached to the SRS components. Follow the instructions on the labels.
  12. After work on the SRS is completed, check the SRS warning light.
