PRECAUTIONS
[RS5F51A]
PRECAUTIONS PFP:00001 Caution ECS0093X
● Do not reuse transaxle oil, properly dispose of it after it has been drained out.
● Check the oil level or replace the oil o nly with the vehicle parked on level ground.
● During removal or installation, keep inside of transaxle cl ear of dust or dirt.
● Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts when applied.
● In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, us e it.
● Be careful no t to damage sliding surfaces and mating surfac es.
