GENERAL DESCRIPTION

C: CAUTION

• Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
• Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
• Keep the disassembled parts in order and pro-
tect them from dust or dirt.
• Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement.

• Be careful not to burn your hands, because each
part on the vehicle is hot after running.
• Be sure to tighten fasteners including bolts and
nuts to the specified torque.
• Place shop jacks or safety stands at the specified
points.
• Before disconnecting electrical connectors of
sensors or units, be sure to disconnect ground ca-
ble from battery.
• Place “NO FIRE” signs near the working area.
• Be careful not to spill fuel on the floor.
