WARNING:

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

To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.

NOTE:

After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 2 minutes before disconnecting the cable from the negative (-) auxiliary battery terminal.
When the cable is disconnected from the negative (-) auxiliary battery terminal and the security lock setting has been enabled, multi-display operations will be disabled upon next startup unless the password is entered. Be sure to check the security lock setting before disconnecting the cable from the negative (-) auxiliary battery terminal.
