NOTICE:

for HV Model:

After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Audio and Visual System (for HV Model))

for Gasoline Model:

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 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System and Audio and Visual System (for Gasoline Model))
