NOTE:

After the ignition switch is turned off, the radio and display receiver assembly or the radio receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
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 Navigation System)
If the HV battery has been struck or dropped, replace it.
When connecting a connector to the HV battery, confirm that the connector is securely connected through the following:
- Push the connector until a click sound is heard.

- Visually check and confirm that the connector is securely connected by pulling on it.
Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.
If the HV battery is stored without insulating the connectors and terminals, electric shock or fire may result.
When performing repairs around the HV battery, such as using a tap, do not allow metal shavings to enter the HV battery.
Do not touch any high voltage wire harnesses, connectors or parts with bare hands.

Hold the areas shown in the illustration and lift the HV battery.
