   1	Attire	Always wear a clean uniform. Hat and safety shoes must be worn.
   2	Vehicle protection	Prepare a grille cover, fender cover, seat cover and floor mat before starting the operation.
   3	Safe operation	Use wheel chocks to secure the vehicle. When working with the engine running, make sure to provide ventilation for exhaust fumes in the workshop. When removing or installing heavy parts, such as the engine, transmission, differential, etc., before starting work make sure there are no problems with the equipment that will be used. When working with 2 or more persons, be sure to check safety for one another. If working on high temperature, high pressure, rotating, moving, or vibrating parts, wear appropriate safety equipment and take extra care not to injure yourself or others.
   4	Preparation of tools and measuring gauge	Before starting operation, prepare a tool stand, SST, gauge, oil and parts for replacement.
   5	Removal and installation, disassembly and assembly operations	Diagnose with a thorough understanding of proper procedures and of the reported problem. Before removing the parts, check the general condition of the assembly and for deformation and damage. When the assembly is complicated, take notes. For example, note the total number of electrical connections, bolts, or hoses removed. Add matchmarks to insure reassembly of components in the original positions. Temporarily mark hoses and their fittings if needed. Clean and wash the removed parts if necessary and assemble them after a thorough check.
   6	Removed parts	Place the removed parts in a separate box to avoid mixing them up with the new parts or contaminating the new parts. For non-reusable parts such as gaskets, O-rings, and self-locking nuts, replace them with new ones as instructed in this service information. Retain the removed parts for customer inspection, if requested.
   7*	Checks to perform after work is finished	Make sure that removed and installed parts (oil filler cap, level dipstick, floor mat, etc.) are properly installed/tightened. Make sure that none of the cloths or tools that were used have been left in the engine compartment or within the vehicle. Check that there are no oil leaks.

   WARNING:

   *: Be sure to perform these checks properly. Not performing these checks properly after finishing work can lead to serious accident or injury.

2. JACKING UP AND SUPPORTING VEHICLE
   1. Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.
3. PRECOATED PARTS
   1. Precoated parts are bolts and nuts that are coated with a seal lock adhesive at the factory.

      *a	Seal Lock Adhesive

   2. If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.
   3. When reusing a precoated part, clean off the old adhesive and dry the part with compressed air. Then apply new seal lock adhesive appropriate to that part.
   4. Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden.
4. GASKETS
   1. When necessary, use a sealer on gaskets to prevent leaks.
5. BOLTS, NUTS AND SCREWS
   1. Carefully follow all the specifications for tightening torques. Always use a torque wrench.
6. FUSES

   1. When inspecting a fuse, check that the wire of the fuse is not broken.
   2. If the wire of a fuse is broken, confirm that there are no shorts in its circuit.
   3. When a fuse is replaced, a fuse with the same amperage rating must be used.

    1. Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with the torque wrench.
       Fig 7: Identifying Torque Wrench With Extension Tool (2 Of 2)

       Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

       Formula

       T' = L2/(L1 + L2) * T

       T'	Reading of torque wrench {N*m (kgf*cm, ft.*lbf)}
       T	Torque {N*m (kgf*cm, ft.*lbf)}
       L1	Length of SST or extension tool {cm (in.)}
       L2	Length of torque wrench {cm (in.)}

       NOTE:

       If an extension tool or SST is combined with a torque wrench and the wrench is used to tighten to a torque specification in this service information, the actual torque will be excessive and parts will be damaged.

The SCION tC is equipped with a Supplemental Restraint System (SRS). The SRS of this vehicle consists of the following:
