Solution

1. Preparation

Gather tools: multimeter, socket set, cleaning supplies.
Ensure the vehicle is in a safe location and the parking brake is engaged.

2. Check and Replace the 12V Battery

Disconnect the Battery:
- Locate the 12V battery in the front trunk.
- Use a socket set to remove the negative terminal first, followed by the positive terminal.
Inspect the Battery:
- Use a multimeter to test the battery voltage.
- If the voltage is low (below 12.4 volts), consider replacing the battery.
Replace the Battery:
- Remove the old battery carefully.
- Install a new compatible 12V battery, ensuring it is securely mounted.
- Connect the positive terminal first, followed by the negative terminal.

3. Inspect Battery Connections

Clean Terminals:
- Use a wire brush to clean any corrosion from the battery terminals and cable ends.
- Reattach the cables securely to ensure a solid connection.

4. Check Fuses

Locate Fuse Box:
- Refer to the vehicle's manual for the location of the fuse box.
Inspect Fuses:
- Identify fuses associated with the starting and electrical systems.
- Replace any blown fuses with the same amperage rating.
