CAUTION:

*a Object Exceeding Weight Limit of Engine Lifter

The engine assembly with transaxle is very heavy. Be sure to follow the procedure described in the repair manual, or the engine lifter may suddenly drop or the engine assembly with transaxle may fall off the engine lifter.
To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.
*a Object Exceeding Weight Limit of Transmission Jack

The automatic transaxle assembly is very heavy. Be sure to follow the procedure described in the repair manual, or the transmission jack may suddenly drop.

Note

If automatic transaxle parts are replaced, refer to Parts Replacement Compensation Table to determine if any additional operations are necessary.
