To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.
To prevent burns, do not touch the engine, exhaust pipe or other high temperature components while the engine is hot.
To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.

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.

*a	An Object Exceeding Weight Limit of Engine Lifter

NOTICE:

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, be sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) auxiliary battery terminal.

Waiting Time before Disconnecting Cable from Negative (-) Auxiliary Battery Terminal

System Name	See Procedure
Vehicle enrolled in Toyota Audio Multimedia system or safety connect system	6 minutes
Vehicle not enrolled in Toyota Audio Multimedia system and safety connect system	1 minute

If the ECM has been struck or dropped, replace it.
Perform Vehicle Identification Number (VIN) registration when replacing the ECM.
