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.

9. 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 damage the hose.

   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, air may leak. Use a step-down adapter if necessary.

10. TORQUE WHEN USING TORQUE WRENCH WITH EXTENSION TOOL

Fig 8: Identifying Torque Wrench Dimension

1. Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with the torque wrench.

   Formula: T1 = L2/(L1 + L2) * T 

   Fig 9: Identifying SST Dimension

   Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
   FORMULA REFERENCE
   
   

   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 manual, the actual torque will be excessive and parts will be damaged.

The 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 the 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, 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 system memory. The back-up power source may inadvertently power the SRS and cause it to deploy.
   3. In minor collisions 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.

      (See DISPOSAL for steering pad)

      (See DISPOSAL for front passenger airbag assembly)

      (See DISPOSAL for front seat side airbag assembly)

      (See DISPOSAL for curtain shield airbag assembly)

      (See DISPOSAL for front seat outer belt assembly)

   4. Never use 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 all airbag sensor assemblies and all airbag assemblies.
      1. Steering pad
      2. Front passenger airbag assembly
      3. Front seat side airbag assembly
      4. Curtain shield airbag assembly
      5. Front seat outer belt assembly
   7. Replace the airbag sensor assemblies and the airbag assemblies if: 1) damage has occurred from being dropped, or 2) cracks, dents or other defects in the case, bracket or connector are present.
   8. Do not directly expose the airbag sensor assembly or airbag assembly to hot air or flames.
   9. Use a voltmeter / ohmmeter with high impedance (minimum=10 kΩ) for troubleshooting electrical circuits.
   10. Information labels are attached to the SRS components. Follow the instructions on the labels.
   11. After work on the SRS is completed, check the SRS warning light.
2. SPIRAL CABLE
   1. The steering wheel must be fitted correctly to the steering column with the spiral cable at the neutral position, as cable disconnection and other problems may occur. Refer to the information about correct installation of the steering wheel (See INSTALLATION ).

3. STEERING PAD
   1. Always place a removed or new steering pad surface upward as shown in the illustration. Placing the steering pad of with the pad surface facing down could cause a serious accident if the airbag inflates. Also, do not place anything on top of the steering pad.

   2. Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which could cause serious injury.
      Fig 12: Precaution Never Use An Ohmmeter On An Airbag

   3. Grease or detergents of any kind should not be applied to the steering pad.
   4. Store the steering pad in an area where the ambient temperature is below 93°C (200°F), the humidity is not high and there is no electrical noise.
   5. When using electric welding anywhere on the vehicle, disconnect the center airbag sensor assembly connectors. These connectors contain shorting springs. This feature reduces the possibility of the airbag deploying due to current entering the squib wiring.
   6. When disposing of the vehicle or the steering pad by itself, the airbag should be deployed using SST before disposal (See DISPOSAL ). Activate the airbag in a safe place away from electrical noise.
4. FRONT PASSENGER AIRBAG ASSEMBLY
   1. Always place a removed or new front passenger airbag assembly with the pad surface facing upward as shown in the illustration. Placing the airbag assembly with the airbag inflation direction facing down could cause a serious accident if the airbag inflates.

   3. Grease or detergents of any kind should not be applied to the front passenger airbag assembly.
   4. Store the airbag assembly in an area where the ambient temperature is below 93°C (200°F), the humidity is not high and there is no electrical noise.
   5. When using electric welding anywhere on the vehicle, disconnect the center airbag sensor assembly connectors. These connectors contain shorting springs. This feature reduces the possibility of the airbag deploying due to current entering the squib wiring.
   6. When disposing of the vehicle or the airbag assembly unit by itself, the airbag should be deployed using SST before disposal (See DISPOSAL ). Activate in a safe place, away from electrical noise.
5. FRONT SEAT SIDE AIRBAG ASSEMBLY
   1. Always place a removed or new front seat side airbag assembly with the airbag inflation direction facing up.
   2. Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which could cause serious injury.

   3. Grease or detergents of any kind should not be applied to the front seat side airbag assembly.
   4. Store the airbag assembly in an area where the ambient temperature is below 93°C (200°F), the humidity is not high and there is no electrical noise.
   5. When using electric welding anywhere on the vehicle, disconnect the center airbag sensor assembly connectors. These connectors contain shorting springs. This feature reduces the possibility of the airbag deploying due to current entering the squib wiring.
   6. When disposing of a vehicle or the airbag assembly unit by itself, the airbag should be deployed using SST before disposal (See DISPOSAL ). Activate in a safe place away from electrical noise.
6. CURTAIN SHIELD AIRBAG ASSEMBLY
   1. Always place a removed or new curtain shield airbag assembly in a clear plastic bag, and keep it in a safe place.
