2. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER

HINT: The CAMRY is equipped with a Supplemental Restraint System (SRS) and seat belt pretensioner.

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. Malfunction symptoms of the SRS are difficult to confirm so 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. To avoid serious injury, servicing the SRS must be started 90 seconds after:
  • The ignition switch is turned to the LOCK position.
  • The negative (−) terminal cable is disconnected from the battery.

(The SRS is equipped with a back−up power source. If work is started within 90 seconds of disconnecting the negative (−) terminal cable from the battery, the SRS may deploy).

Disconnecting the negative (−) terminal cable will erase clock memory and audio system presets.

Mark down data as necessary before disconnecting the cable.

CAUTION: Never use a back−up power source (battery or other) avoid erasing system memory. The back−up power source may power the SRS, leading to a possible SRS and cause it to deploy.

  1. In minor collisions where the SRS does not deploy, the horn button assembly, instrument panel passenger airbag assembly front seat airbag assembly, curtain shield airbag assembly and seat belt pretensioner should be inspected before further use of the vehicle (See pages 60−27, 60−40, 60−53, 60−47 and 61−7).
  2. Never use SRS parts from another vehicle. When replacing parts, use new parts.
  3. (Before repairs, remove the airbag if impacts are likely to be applied to the during repairs.
