Ensure the vehicle is in a safe, well-ventilated area.
Note that all procedures should be performed with the vehicle powered off.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Open the front trunk to access the 12V battery.
2. Disconnect the negative terminal first, then the positive terminal (use a socket set).
3. Inspect terminals for corrosion; clean them with a wire brush if necessary.
4. Reconnect the positive terminal first, followed by the negative terminal.

3. Test and Replace the 12V Battery

Sub-steps:
1. Use a multimeter to check the voltage of the 12V battery (should be above 12.4V).
2. If the voltage is low, replace the 12V battery with a new one (ensure you use a compatible battery).
3. Disconnect the old battery, remove it, and install the new battery in reverse order.
4. Secure all connections and close the front trunk.

4. Check Main Battery Pack

Sub-steps:
