Solution

1. Preparation

Gather necessary tools: flashlight (if needed for visibility), clean cloth.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Brake Fluid Reservoir

Use the flashlight to enhance visibility if necessary.
Carefully inspect the reservoir for the fluid level indicated by the "MIN" and "MAX" markers.
If the fluid is below the "MIN" line, proceed to the next step.

3. Add Brake Fluid

Use a clean, funnel to prevent contamination.
Select the appropriate brake fluid type as specified in the owner’s manual (usually DOT 3 or DOT 4).
Slowly add brake fluid until it reaches the "MAX" line, being careful not to overfill.
Wipe away any spills with the clean cloth.

4. Reassemble and Check for Leaks

Ensure the brake fluid reservoir cap is securely tightened after adding fluid.
Inspect the area around the reservoir for any signs of leaks or spills.
Close the frunk securely.
