Solution

1. Preparation

Gather necessary tools: clean cloth, funnel, and new brake fluid (DOT 4 for Porsche Cayenne).
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect Brake Fluid Reservoir

Locate the brake fluid reservoir cap and clean its exterior with a clean cloth to prevent contamination.
Carefully remove the cap, taking care not to introduce dirt into the reservoir.

3. Check Fluid Level

Look at the brake fluid level against the "MIN" and "MAX" markings on the side of the reservoir.
If the fluid is below the "MIN" mark, it needs to be topped up.

4. Add Brake Fluid

Using a funnel, add the appropriate DOT 4 brake fluid slowly to avoid overfilling.
Fill until the fluid level reaches the "MAX" mark, ensuring not to spill any fluid on the surrounding components.

5. Reassemble

Replace the reservoir cap securely to prevent contamination.
Close the hood, ensuring it is latched properly.
