Solution

1. Preparation

Gather necessary tools: clean cloth, funnel (if adding fluid).
Ensure the vehicle is parked on a level surface and turned off.

2. Inspect Brake Fluid Level

Locate the brake fluid reservoir cap and check if it is secure.
Clean the area around the reservoir cap to prevent contamination when opening.
Remove the cap and inspect the fluid level against the markings on the side of the reservoir.
- If the fluid is below the minimum mark, it is necessary to add brake fluid.

3. Add Brake Fluid (if needed)

Use only the recommended brake fluid type (typically DOT 3 or DOT 4; consult the owner's manual for specifics).
Using a clean funnel, carefully add fluid until it reaches the maximum fill line.
Avoid overfilling, as this can cause pressure issues in the brake system.

4. Secure the Reservoir Cap

Clean any excess fluid from the reservoir area.
Replace the reservoir cap securely to prevent contamination and pressure loss.

5. Clean Up

Dispose of any used materials properly.
Store tools and ensure the frunk is closed.
