PRECAUTIONSPFP:00001
Service Notice or PrecautionsECS008BM
Do not reuse transaxle oil, once it has been drained.
Check oil level or replace oil with vehicle on level surface.
During removal or installation, keep inside of transaxle clear of dust or dirt.
Check for the correct installation status prior to removal or disassembly. If matching mark are required, be
certain they do not interfere with the function of the parts they are applied.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
Be careful not to damage sliding surfaces and mating surfaces.
