Operating (Usage)
Once correctly installed, the Thule Evo Flush Rail Kit serves as the foundational mounting point for your Thule Evo roof rack system. This kit is not a standalone cargo carrier but an essential component that connects the roof rack feet to your vehicle's integrated flush rails.
- Load Capacity: Always adhere to the maximum load capacity specified by both your vehicle manufacturer and Thule for the entire roof rack system. Overloading can compromise safety and damage your vehicle.
- Secure Attachment: Ensure that any cargo or accessories mounted on the roof rack are securely fastened to prevent movement during transit.
- Driving Considerations: Be aware of increased vehicle height and potential changes in driving dynamics (e.g., wind resistance, cornering stability) when carrying loads on the roof.
- Regular Checks: Periodically check the tightness of all mounting bolts and connections, especially after initial installation and before long journeys.
Maintenance
Proper maintenance will extend the lifespan of your Thule Evo Flush Rail Kit and ensure continued safe operation.
- Cleaning: Clean the kit components regularly with mild soap and water. The primary material, Acrylonitrile Butadiene Styrene (ABS), is durable but can be affected by harsh chemicals. Avoid abrasive cleaners.
- Inspection: Periodically inspect all parts for signs of wear, damage, or corrosion. Pay close attention to the metal clamping mechanisms and plastic bases.
- Fastener Checks: Regularly check the tightness of all bolts and fasteners. Vibrations during driving can cause them to loosen over time.
- Storage: If removing the kit for extended periods, store it in a clean, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
This section addresses common issues you might encounter with your Thule Evo Flush Rail Kit.
- Issue: Kit does not fit the vehicle.
Solution: Double-check the Thule online buyers' guide and your vehicle's specifications to ensure you have the correct kit model (186064) for your specific Hyundai I30 SW (2018-) model. Ensure the vehicle has integrated flush rails.
- Issue: Loose or rattling components after installation.
Solution: Re-check all fasteners and mounting points. Ensure they are tightened to the recommended torque specifications as per the assembly instructions. Vibrations can cause loosening; regular checks are important.
- Issue: Excessive wind noise.
Solution: While some wind noise is normal with roof rack systems, excessive noise might indicate improper installation or incorrect positioning of components. Verify that all parts are installed flush and securely, and that no gaps are present where air could create turbulence. Ensure the roof bars (if already installed) are correctly positioned.
- Issue: Damage to vehicle paintwork.
Solution: Ensure all contact points between the kit and the vehicle are clean before installation. Follow the assembly instructions precisely to avoid overtightening or incorrect placement that could cause abrasion. Protective films or pads, if supplied, must be used.
If you encounter issues not covered here, please refer to the comprehensive assembly instructions or contact Thule customer support.
