General Description
B: 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 rigid racks at the specified
points.
Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground
cable from battery.
