Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Allow the vehicle to cool down for at least 30 minutes to avoid burns.

2. Open the Front Trunk

Pull the frunk release lever inside the vehicle or use the Tesla app.
Lift the frunk lid gently and secure it.

3. Locate the Coolant Reservoir

Identify the coolant reservoir, which is typically a translucent plastic container located near the front of the vehicle.
Refer to the owner's manual for the exact location if necessary.

4. Check Coolant Level

Inspect the side of the reservoir for the minimum and maximum level markings.
If the coolant level is below the minimum mark, you will need to add coolant.

5. Add Coolant (if necessary)

Use Tesla-approved coolant (specifically formulated for electric vehicles).
Remove the reservoir cap carefully, avoiding any spillage.
Add coolant until the level reaches the maximum mark.
Replace the cap securely.
