Part 1 of 2

1. BASIC REPAIR HINT
(a) HINTS ON OPERATIONS









(b) 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.





(c) 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 appropriately to that part.
(4) Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden.

(d) GASKETS
(1) When necessary, use a sealer on gaskets to prevent leaks.
(e) BOLTS, NUTS AND SCREWS
(1) Carefully follow all the specifications for tightening torques. Always use a torque wrench.
(f) 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.






(g) CLIPS
(1) The removal and installation methods of typical clips used for vehicle body parts are shown in the table below.
HINT: If clips are damaged during work, always replace the damaged clips with new ones.









(h) CLAWS
(1) The removal and installation methods of typical claws used for vehicle body parts are shown in the table below.
HINT: If claws are damaged during a procedure, always replace the cap or cover that has damaged claws with a new one.





(i) HINGE, GUIDE, CLAMP AND PIN ETC.
(1) The removal and installation methods of typical hinge, guide, clamp and pin used for vehicle body parts are shown in the table below.
HINT: If clamps are damaged during a procedure, always replace the cap or cover that has damaged clamps with a new one.





(j) 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.
(k) TORQUE WHEN USING TORQUE WRENCH WITH EXTENSION TOOL








(1) Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with a torque wrench.
Formula:
T' = L2/(L1 + L2) * T





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

2. 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 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 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 the 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, driver side knee 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.
(4) Never use the 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. Driver side knee airbag assembly
4. Front seat side airbag assembly
5. Curtain shield airbag assembly
6. 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 assemblies or airbag assemblies to hot air or flames.
(9) Use a voltmeter/ohmmeter with high impedance (minimum = 10 kOhms) 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.
