INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (Continued..)
7. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
This vehicle is equipped with a Supplemental Restraint System (SRS).
CAUTION:
* Before performing pre-disposal deployment of any SRS component, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.
* 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 section carefully.
(a) 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 auxiliary battery.
(2) Work must not be started until at least 90 seconds after the power switch is turned off and after the cable is disconnected from the negative (-) auxiliary battery terminal.
The SRS is equipped with a back-up power source. If work is started within 90 seconds after turning the power switch off and disconnecting the cable from the negative (-) auxiliary battery terminal, the SRS may deploy.
When the cable is disconnected from the negative (-) auxiliary battery terminal, the clock and audio system memory will be cleared. 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 (auxiliary battery or other) to avoid clearing 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, knee airbag assembly, 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 SRS parts from another vehicle. When replacing parts, use new ones.
(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.
