CAUTION

When performing service operation, refer to “Repair Contents” in “General Description”. REPAIR CONTENTS>Repair Contents
Prior to starting work, pay special attention to the following:
1. Always wear work clothes, a work cap, and protective shoes. Additionally, wear a helmet, protective goggles, etc. if necessary.
2. Protect the vehicle using a seat cover, fender cover, etc.
3. Prepare the service tools, clean cloth, containers to catch grease and oil, etc.
Prevent scattering of grease and oil. If it scatters, wipe it off immediately to prevent it from penetrating the floor or flowing out, to protect the environmental.
If the grease and oil is spilt over the engine, exhaust pipe or the under cover, completely wipe it off to avoid emission of smoke or causing a fire.
Vehicle components are extremely hot immediately after driving. Be wary of receiving burns from heated parts.
When performing a repair, identify the cause of trouble and avoid unnecessary work.
Before disconnecting connectors of sensors or units, be sure to disconnect the ground terminal from the battery sensor.
Always use the jack-up point when the lifting device, shop jacks or rigid racks are used to support the vehicle.
Before starting works, remove dirt and corrosion around the target area.
Keep the removed parts in order and protect them from dust and dirt.
All removed parts, if to be reused, should be reinstalled in the original positions with attention to the correct directions, etc.
For the parts except for the non-reusable parts, replace then with new parts if necessary.
Be sure to tighten bolts and nuts to the specified torque.
Always use new application oil during work.
Follow all government and local regulations concerning disposal of refuse when disposing of engine oil.
