CAUTION
 Only use transmission fluid of the specified brand. Use of transmission fluid other than specified
will impair driveability and CVT endurance, and may lead to breakage of CVT.
 Disassembly work should be done in a clean dust-proof room.
 Prior to disassembly, clean any sand or dirt adhered to the outer parts of transaxle using steam,
washing oil or another solvent, outside the clean room, so as not to contaminate inner parts of
transaxle during disassembly or assembly. (Do not allow steam to get inside the transaxle, and do
not clean rubber parts with washing oil.)
 After cleaning, remove the torque converter, and drain the transmission fluid.
 Disassembly and assembly work should be done with bare hands or using plastic gloves.
 Do not touch inner parts of the transaxle after touching its outer parts. (Wash hands after touching
the outer parts.)
 Do not use cotton gloves and rags to prevent from lint; instead, use paper rags.

 Prior to assembly or disassembly work, make sure conditions are appropriate.
 Do not re-use the drained transmission fluid.
