Title: INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION; 2017 MY Sienna [08/2016 - 11/2017]

INITIALIZATION

1. PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

Necessary Procedure	Effect / Inoperative Function When Necessary Procedures are not Performed	See Page
Reset slide door close position	Power slide door function
Reset slide door close position	Slide door closer function
Reset back door close position	Power back door function
Reset back door close position	Back door closer function

NOTICE:

w/ Navigation System (for SD):

After the ignition switch is turned off, the navigation receiver assembly (Navigation System (for SD)) records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.
