Solution

1. Preparation

Gather necessary tools: clean cloth or dipstick.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Checking the Brake Fluid Level

Open the hood of the vehicle and secure it with the prop rod.
Locate the brake fluid reservoir, which is typically a small, semi-transparent container marked with a brake symbol.

3. Inspecting the Fluid Level

Observe the fluid level through the reservoir; it should sit between the "MIN" and "MAX" lines.
If the fluid is below the "MIN" line:
- Clean the reservoir cap area with a cloth to prevent contaminants from entering.
- Remove the cap carefully, avoiding any spillage.

4. Adding Brake Fluid (if necessary)

Use DOT 3 or DOT 4 brake fluid, as specified in the owner's manual.
Pour the brake fluid into the reservoir until the level reaches the "MAX" mark.
Replace the reservoir cap securely and wipe any spills.
