Repair Instruction: Precaution
- BASIC REPAIR HINT
- HINTS ON OPERATIONS
- JACKING UP AND SUPPORTING VEHICLE
- Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.
- PRECOATED PARTS
- Precoated parts are bolts and nuts that are coated with a seal lock adhesive at the factory.
- If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.
- 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.
- Some seal lock agents harden slowly You may have to wait for the seal lock adhesive to harden.
- GASKETS
- When necessary, use a sealer on gaskets to prevent leaks
- BOLTS, NUTS AND SCREWS
- Carefully follow all the specifications for tightening torques. Always use a torque wrench.
- FUSES
- When inspecting a fuse, check that the wire of the fuse is not broken.
- When replacing fuses, be sure that a new fuse has the correct amperage rating. Do not exceed the rating or use one with a lower rating.FUSES REFERENCE CHART

- FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
This vehicle is equipped with a Supplemental Restraint System (SRS)
CAUTION: 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 article carefully.- GENERAL NOTICE
- 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
- Work must be started at least 90 seconds after the engine 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 engine 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, the clock and audio system memory is cleared 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 clearing the system memory. The back-up power source may inadvertently power the SRS and cause it to deploy. - In minor collisions where the SRS does not deploy, the steering pad, front passenger airbag assembly, driver side knee airbag assembly, front passenger side knee airbag assembly, front seat side airbag assembly, curtain shield airbag assembly, front seat outer belt assembly and rear seat outer belt assembly should be inspected before further use of the vehicle

- REMOVING AND INSTALLING FUEL SYSTEM PARTS
- Prepare a fire extinguisher before starting the operation
- To prevent static electricity, install a ground wire to the fuel changer, vehicle and fuel tank, and do not spray the surrounding area with water. Be careful when performing work in this area, as the work surface will become slippery. Do not clean up gasoline spills with water, as this may cause the gasoline to spread, and possibly create a fire hazard
