    Note

    After the engine switch is turned off, the multi-media module receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make 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
    Specification Waiting Time
    w/o Telematics transceiver 60 sec.
    w/ Telematics transceiver 120 sec.
