1. PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

Necessary Procedure

Effect / Inoperative Function When Necessary Procedures are not Performed

See Page

Reset back door close position
  • Power back door function
  • Back door closer function


NOTICE:

  • It may not be possible to release the steering lock or start the engine when the battery voltage is low. If this occurs, initialization of the steering lock system is required. (See page )
  • Audio and Visual System:

    After the ignition switch is turned off, the radio and display receiver assembly 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.

  • Navigation System:

    After the ignition switch is turned off, the navigation receiver assembly 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.
