Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface, and the engine is off.
Wear safety gloves and goggles.

2. Locating the Brake Fluid Reservoir

Open the hood of the Porsche Cayenne E3.
Secure the hood with the prop rod if necessary.
Locate the brake fluid reservoir, which is typically near the back of the engine bay, near the driver's side.

3. Checking the Fluid Level

Clean the area around the reservoir cap to prevent debris from entering the system.
Remove the cap carefully by turning it counterclockwise.
Visually inspect the fluid level against the "MIN" and "MAX" indicators on the reservoir. The fluid should be between these two levels.
If the fluid is low, proceed to add the appropriate brake fluid.

4. Adding Brake Fluid

Use a funnel to prevent spills and carefully pour the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual) into the reservoir until the fluid level reaches the "MAX" line.
Avoid overfilling the reservoir to prevent spillage and brake system malfunction.
Replace the cap securely after filling.

5. Final Inspection

Inspect the brake lines and components for any leaks or damage.
Close the hood securely after the inspection.
