Initialization [08/2012 - ]

  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 [08/2012 - ]
    NOTE:

    After the engine switch is turned off, the multi-media module receiver assembly (w/ Multi-display) records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.
