Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools: clean cloth and funnel (if adding coolant).

2. Inspect Coolant Level

Visually check the coolant level against the markings on the reservoir.
If the level is below the minimum mark, proceed to add coolant.

3. Add Coolant

Remove the cap from the coolant reservoir by turning it counterclockwise.
Using a funnel, slowly add the recommended coolant (Tesla recommended coolant or equivalent) until it reaches the maximum level.
Replace the cap securely by twisting it clockwise.

4. Clean Up

Wipe any spills with a clean cloth to prevent residue buildup.
Ensure that all tools and materials are removed from the frunk.
