CAUTION

  1. Prior to starting work, pay special attention to the following: Always wear work clothes, a safety cap, protective shoes. Additionally, wear a helmet, protective goggles, etc. if necessary. Protect the vehicle using a seat cover, fender cover, etc. Prepare the service tools, clean cloth, containers to catch grease and oil, etc.
  2. Prepare a container and cloth to prevent scattering of engine coolant when performing work where engine coolant can be spilled. If the oil spills, wipe it off immediately to prevent from penetrating into floor or flowing out for environmental protection.
  3. Vehicle components are extremely hot immediately after driving. Be wary of receiving burns from heated parts.
  4. When performing a repair, identify the cause of trouble and avoid unnecessary removal, disassembly and replacement.
  5. Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from battery.
  6. Always use the jack-up point when the shop jacks or rigid racks are used to support the vehicle.
  7. Remove contamination including dirt and corrosion before removal, installation, disassembly or assembly.
  8. Keep the removed parts in order and protect them from dust and dirt.
  9. All removed parts, if to be reused, should be reinstalled in the original positions with attention to the correct directions, etc.
  10. Bolts, nuts and washers should be replaced with new parts as required.
  11. Be sure to tighten the fasteners including bolts and nuts to the specified torque.
  12. Follow all government and local regulations concerning disposal of refuse when disposing engine coolant.
