Your vehicle uses an additional 12V parking lithium battery to secure stable operation power supply when you operate certain functions while parking, such as Over-The-Air (OTA) software update, air conditioning (A/C) automatic drying, and CCS.

If the 12V lithium auxiliary battery detects an abnormality (such as high temperature or overcharging), the instrument cluster displays a warning message, or the vehicle sends a malfunction alert text message to the registered mobile phone number.
