Solution

1. Preparation

Ensure the vehicle is in a safe area and the parking brake is engaged.
Gather necessary tools: multimeter, jumper cables or jump starter, and a socket set.

2. Check and Replace the 12V Battery

Disconnect the Battery:
- Open the front trunk (frunk) and locate the 12V battery.
- Use a socket set to remove the negative terminal first, then the positive terminal.
Inspect and Clean:
- Check for corrosion on the battery terminals; clean with a wire brush if necessary.
- Visually inspect the battery for any signs of damage or swelling.
Test Battery Voltage:
- Use a multimeter to measure the voltage of the 12V battery. If it’s below 12.4V, consider replacing it.
Replace the Battery (if necessary):
- If the battery is faulty, replace it with a new compatible 12V battery.
- Reconnect the positive terminal first, followed by the negative terminal. Torque to manufacturer's specifications.

3. Jump-start the Vehicle

Connect Jumper Cables:
- Connect the positive (red) cable to the positive terminal of the dead 12V battery and the other end to the donor battery.
- Connect the negative (black) cable to the negative terminal of the donor battery and attach the other end to a grounded metal part of the Tesla.
Start the Donor Vehicle:
- Start the vehicle providing the jump and let it run for a few minutes.
Start the Tesla:
- Attempt to start the Tesla Model S Plaid. If successful, allow the vehicle to run to recharge the 12V battery.
