PROCEDURES NECESSARY WHEN AUXILIARY BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

Necessary Procedures	Effect / Inoperative Function When Necessary Procedures are not Performed	See Page
Correct the steering angle neutral point	Intelligent parking assist system	Click here
Back door lock	Power door lock control system	Click here

Note

After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 90 seconds*1 or 120 seconds*2*4 before disconnecting the cable from the negative (-) auxiliary battery terminal.
After the power switch is turned off, the navigation receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 90 seconds*3 before disconnecting the cable from the negative (-) auxiliary battery terminal.
When the auxiliary battery is replaced or the cable is disconnected from its negative (-) auxiliary battery terminal, the ISC learning value will be initialized and symptoms as a loud rattle from the hybrid vehicle transaxle assembly may occur until ISC learning is performed. Therefore, perform ISC learning when the auxiliary battery is replaced or the cable is disconnected from the negative (-) terminal of the auxiliary battery Click here.
