Solution

1. Preparation

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

2. Access the Brake Fluid Reservoir

Open the hood of the vehicle.
Secure the hood with the prop rod if necessary.

3. Inspect and Check Fluid Level

Locate the brake fluid reservoir, typically a translucent plastic container with a cap labeled "brake fluid."
Use the clean cloth to wipe any dirt off the reservoir cap to prevent contamination when opened.
Check the fluid level against the "MIN" and "MAX" markings on the side of the reservoir.

4. Add Brake Fluid (if necessary)

If the fluid is below the "MIN" line, remove the cap carefully.
Using a funnel, add the recommended brake fluid type (usually DOT 4 for Volkswagen vehicles) until the level reaches the "MAX" line.
Do not overfill the reservoir.

5. Secure the Reservoir and Close the Hood

Replace the cap securely onto the brake fluid reservoir.
Ensure it is tightened properly to prevent leaks.
Close the hood of the vehicle.
