- Familiarize yourself with your vehicle's interior trim removal procedures.
5.2. Installation Steps (General Overview)
- Remove Original Air Vents: Carefully remove the existing air vents from the dashboard and, if applicable, the rear passenger area. This typically involves prying off trim pieces and unclipping the vents.
- Install LED Air Vents: Insert the new LED air vents into the vacant slots. Ensure they fit securely.
- Connect Wiring Harnesses: Connect the provided wiring harnesses to the LED air vents. These harnesses will then connect to the control module and integrate with your car's existing ambient lighting wiring.
- Install Control Module: Securely mount the control module in a discreet location, ensuring it is protected from moisture and excessive heat.
- Connect to Vehicle's Electrical System: Connect the main power and signal wires from the control module to the appropriate points in your vehicle's electrical system, typically tapping into the existing ambient lighting circuit. This step requires knowledge of automotive wiring diagrams.
- Test Functionality: Reconnect the vehicle's battery and turn on the ignition. Test all LED air vents to ensure they light up and respond to the car's ambient lighting controls.
- Reassemble Interior Trim: Carefully reassemble all removed interior trim pieces.


6. Operation
The LED air vents are designed to synchronize with your Mercedes Benz S-Coupe's original ambient lighting system. Once installed correctly, the color and brightness of the LED vents will be controlled through your vehicle's existing infotainment system or dedicated ambient lighting controls.
6.1. Color Mode Selection
Depending on your vehicle's capabilities and the specific kit purchased (7-color or 64-color), you can adjust the ambient light colors directly from your car's settings. The 64-color mode allows for a wide range of customization, enabling you to select multiple ambient light colors to create your desired atmosphere.

6.2. Automatic Synchronization
The system is designed to automatically synchronize with your car's ambient lighting, ensuring a consistent and integrated lighting experience. The lights will turn off synchronously with the car's power.


7. Maintenance
To ensure the longevity and optimal appearance of your LED air vents, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry microfiber cloth to gently wipe the surface of the vents. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive interior cleaner. Avoid harsh chemicals or abrasive materials that could scratch the finish or damage the LED components.
- Avoid Liquid Exposure: While designed for automotive use, avoid direct spraying of liquids onto the vents, especially into the turbine openings, to prevent damage to the electrical components.
- Regular Inspection: Periodically check the vents for any loose connections or signs of wear.
8. Troubleshooting
If you encounter any issues with your LED air vents, please refer to the following common problems and solutions:
- Vents Not Lighting Up:
- Check all wiring connections to ensure they are secure and properly seated.
- Verify that the vehicle's ambient lighting system is active and functioning correctly.
- Inspect fuses related to the ambient lighting system in your vehicle.
- Ensure the control module is receiving power.
- Incorrect Color or Flickering Lights:
- Confirm that the wiring connections are correct according to the installation diagram.
- Check for any loose connections at the control module or individual vents.
- If the issue persists, a reset of the vehicle's electrical system (by temporarily disconnecting the battery) might resolve minor glitches.
- Vents Not Synchronizing with Car's Ambient Lighting:
- Double-check the signal wire connection from the control module to the car's ambient lighting circuit.
- Ensure the control module is correctly configured (if applicable, refer to specific instructions provided with the module).
If these steps do not resolve the issue, please contact customer support for further assistance.
