    Note


    • After the battery is reconnected, be sure to wait 10 seconds or more before attempting to start the engine. The engine may not start immediately after the battery is reconnected.

    • w/ Navigation System:

      After the engine switch is turned off, the navigation system requires approximately a minute to record various types of memory and settings. As a result, after turning the engine switch off, wait a minute or more before disconnecting the cable from the negative (-) battery terminal.
