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.
