Solution

1. Preparation

Gather necessary tools: flashlight for visibility and a clean rag.
Ensure the vehicle is parked on a level surface and the engine is cool before checking the coolant.

2. Inspect Coolant Level

With the frunk open, shine the flashlight on the coolant reservoir to better see the level.
Confirm the coolant level is within the acceptable range marked on the reservoir.

3. Add Coolant if Necessary

If the coolant level is below the minimum mark:
- Remove the reservoir cap by twisting it counterclockwise.
- Use the appropriate Tesla-approved coolant, typically a 50/50 mix of water and coolant or pre-mixed from Tesla.
- Pour the coolant into the reservoir until it reaches the maximum line.
- Replace the reservoir cap securely.
