*: When performing learning using the Techstream.

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

WAITING TIME BEFORE DISCONNECTING CABLE FROM NEGATIVE (-) 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

WARNING:

The engine assembly with transaxle is very heavy. Be sure to follow the procedure described in the appropriate service 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.
