Solution

1. Preparation

Gather necessary tools and materials:
- Clean cloth
- Funnel (if adding fluid)
- New brake fluid (DOT 3 or 4, as specified in the owner's manual)
Park the vehicle on a level surface and engage the parking brake.

2. Access the Brake Fluid Reservoir

Open the front trunk (frunk) by pressing the frunk button on the key fob or touchscreen.
Locate the brake fluid reservoir, which is typically marked and positioned near the driver's side.

3. Check Fluid Level

Wipe the area around the reservoir cap with a clean cloth to ensure no debris enters the system.
Carefully open the cap without forcing it.
Visually check the brake fluid level against the markings:
- The fluid should be between the minimum and maximum levels.

4. Add Brake Fluid (if necessary)

If the fluid is below the minimum mark, use a funnel to add new brake fluid up to the maximum level.
Ensure that the fluid is clean and clear; do not mix different types of brake fluid.
Replace the cap securely after adding fluid.

5. Final Checks

Clean any spilled fluid from the reservoir area.
Close the frunk securely.
Dispose of any used materials according to local regulations.
