Repair Instruction: Initialization: Initialization

  1. PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED 
    Necessary Procedures Effect/Inoperative Function When Necessary Procedures are not Performed See
    Correct the steering angle neutral point Parking assist monitor system Refer to INITIALIZATION
    NOTE:

    After the ignition switch is turned off, the navigation receiver assembly (for Navigation Receiver Type) or radio and display receiver assembly (for Radio and Display Type with Intuitive Parking Assist System) 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.
