Solution

1. Preparation

Gather necessary tools: clean cloth, brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Ensure the vehicle is on a level surface and the engine is off.

2. Inspecting Fluid Level

Clean the top of the brake fluid reservoir with a clean cloth to prevent contaminants from entering.
If the fluid is below the "MIN" mark, prepare to add fluid.

3. Adding Brake Fluid

Remove the cap from the brake fluid reservoir carefully.
Using the clean brake fluid, add fluid until it reaches the "MAX" mark.
Avoid overfilling as this can lead to fluid spilling out during braking.

4. Final Steps

Replace the cap securely on the brake fluid reservoir.
Clean any spilled fluid off the reservoir and surrounding areas.
Close the hood securely.
