This vehicle is equipped with a Supplemental Restraint System (SRS).

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 for 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 back-up 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, the 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 back-up power source (battery or other) to avoid erasing the system memory. The back-up power source may inadvertently power the SRS and cause it to deploy.
   3. If the vehicle has been involved in a minor collision where the SRS does not deploy, the steering pad, front passenger airbag assembly, front seat side airbag assembly, curtain shield airbag assembly and front seat outer belt assembly should be inspected before further use of the vehicle.
   4. Never use the SRS parts from another vehicle. When replacing parts, use new parts.
   5. Before repairs, remove the airbag sensor assemblies if impacts are likely to be applied to the sensor during repairs.
   6. Never disassemble and attempt to repair any airbag sensor assemblies or airbag assemblies.
