The engine assembly with transaxle is very heavy. Be sure to follow the procedure described in the repair information , or the engine lifter may suddenly drop or the engine assembly with transaxle may fall off the engine lifter.

*a	An Object Exceeding Weight Limit of Engine Lifter

The hybrid vehicle transaxle assembly is very heavy. Be sure to follow the procedure described in the repair information , or the transmission jack may suddenly drop or a part may fall.

*a	Object Exceeding Weight Limit of Transmission Jack

NOTE:

After the engine switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System)
