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.
   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. When replacing fuses, be sure that the new fuse has the correct amperage rating. Do not exceed the rating or use one with a lower rating.

10. REMOVAL AND INSTALLATION OF VACUUM HOSES
    1. To disconnect a vacuum hose, pull and twist from the end of the hose. Do not pull from the middle of the hose as this may cause damage.

    2. When disconnecting vacuum hoses, use tags to identify where they should be reconnected.
    3. After completing any hose related repairs, double check that the vacuum hoses are properly connected. The label under the hood shows the proper layout.
    4. When using a vacuum gauge, never force the hose onto a connector that is too large. If a hose has been stretched, it may leak air. Use a step-down adapter if necessary.

11. TORQUE WHEN USING TORQUE WRENCH WITH EXTENSION TOOL
    Fig 6: Identifying Torque Wrench With Extension Tool

    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    1. Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with a torque wrench.
       Fig 7: Identifying Length Of SST And Length Of Torque Wrench

       Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

       Formula: 

       T1 = L2 / (L1 + L2) * T 

       LENGTH OF SST AND LENGTH OF TORQUE WRENCH
       
       

       T1	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 information, the actual torque will be excessive and parts will be damaged.
