Solution

1. Preparation

Gather necessary tools and materials: clean cloth or paper towel for cleaning, additional brake fluid if needed.
Ensure the vehicle is on a flat surface to provide an accurate reading.

2. Inspect Brake Fluid Level

Visually check the brake fluid reservoir to see if the fluid level is within the specified range.
If the fluid is low, proceed to the next step.

3. Add Brake Fluid (if necessary)

Tools Required: Funnel (if needed for pouring)
Use a clean cloth to wipe the cap of the brake fluid reservoir to prevent contamination.
Remove the cap of the brake fluid reservoir; be careful not to let any dirt enter the reservoir.
If the fluid level is low, add the appropriate type of brake fluid as specified in the owner's manual (typically DOT 3 or DOT 4).
Safety Warning: Avoid spilling brake fluid on painted surfaces as it can damage the paint.

4. Recheck Fluid Level

After adding fluid, wait a moment and recheck the fluid level to ensure it’s between the "MIN" and "MAX" marks.
Replace the cap securely on the reservoir.

5. Close the Hood

Ensure all tools are removed from the engine bay.
Lower the hood and ensure it is securely closed.
