C: CAUTION

• Wear appropriate work clothing, including a cap, protective goggles and protective shoes when performing
any work.
• Remove contamination including dirt and corrosion before removal, installation or disassembly.
• Keep the disassembled parts in order and protect them from dust and dirt.
• Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
• Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.
• Be sure to tighten fasteners including bolts and nuts to the specified torque.
• Place shop jacks or rigid racks at the specified points.
• Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from the bat-
tery.
• Place “NO OPEN FLAMES” signs near the working area.
• Prepare a container and cloth to prevent scattering of fuels when performing work where fuels can be
spilled. If the fuel spills, wipe it off immediately to prevent from penetrating into floor or flowing out for envi-
ronmental protection.
• Follow all government and local regulations concerning disposal of refuse when disposing fuel.
