4. Setup & Installation
The Thule Evo Flush Rail Fitting Kit 186068 is designed for a vehicle-specific fit. Always refer to the detailed assembly instructions included in your package for precise, step-by-step guidance tailored to your Mazda 6 Sedan (2013-).
4.1 Pre-Installation Checks
- Verify that all components listed in Section 3 are present and undamaged.
- Clean the vehicle's roof and integrated rail areas where the kit will be installed to ensure a secure fit and prevent paint damage.
- Identify the specific mounting points on your vehicle's integrated flush rails as indicated in the detailed instructions.
4.2 Installation Steps (General Overview)
- Attach Brackets: Position the vehicle-specific brackets onto the integrated flush rails according to the detailed instructions. Ensure they align with the designated mounting points.
- Secure with Fasteners: Use the provided fasteners and bolts to secure the brackets to the vehicle. Tighten them to the specified torque settings using an appropriate tool. Over-tightening can damage the vehicle or components; under-tightening can lead to an insecure fit.
- Install Rubber Pads: Place the protective rubber pads between the brackets and the vehicle's surface to prevent scratches and ensure a snug fit.
- Mount Thule Feet: Once the fitting kit is securely installed, attach your Thule Flush Rail feet (sold separately) to the installed brackets, following the instructions provided with the feet.
- Final Check: After installation, gently pull and push on the entire roof rack system to ensure it is firmly attached and does not move. Re-check all fasteners for tightness.
5. Operating Instructions
5.1 Load Capacity
The maximum load capacity for the Thule Evo Flush Rail Fitting Kit, when combined with appropriate Thule feet and bars, is 75 kg (165 lbs). This limit includes the weight of the roof rack system itself. Always adhere to the lower of either the Thule specified load capacity or your vehicle manufacturer's recommended roof load limit.
5.2 Securing Cargo
- Distribute cargo weight evenly across the roof bars.
- Use appropriate Thule accessories (e.g., straps, cargo boxes, bike carriers) to secure items firmly.
- Ensure no part of the cargo obstructs the driver's view or interferes with vehicle operation.
5.3 Driving with a Roof Rack
- Drive at reduced speeds, especially in crosswinds, on rough roads, or when cornering.
- Be mindful of increased vehicle height and width.
- Check the roof rack and cargo for security and tightness frequently during long trips.
6. Maintenance
6.1 Regular Inspection
- Periodically inspect all components of the fitting kit and roof rack system for signs of wear, damage, or corrosion.
- Check the tightness of all bolts and fasteners at least once a month, and always before and after carrying heavy loads or long journeys.
6.2 Cleaning
- Clean the fitting kit and roof bars with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the finish or materials.
- Rinse thoroughly and dry completely to prevent water spots and corrosion.
6.3 Storage
If the roof rack system is not in use for an extended period, consider removing it from the vehicle to reduce wind noise, improve fuel efficiency, and minimize wear on components. Store the kit in a dry, cool place away from direct sunlight.
7. Troubleshooting
7.1 Loose Fit
If the fitting kit or roof rack feels loose after installation or during use:
- Check Torque: Re-tighten all bolts and fasteners to the specified torque settings as per the detailed assembly instructions.
- Verify Placement: Ensure the brackets are correctly positioned on the vehicle's integrated flush rails according to the vehicle-specific instructions.
- Inspect Components: Check for any damaged or missing parts that might compromise the fit.
7.2 Excessive Wind Noise
Some wind noise is normal with a roof rack. However, if it's excessive:
- Check Bar Position: Ensure the roof bars are correctly positioned and spaced according to the instructions.
- Inspect End Caps: Verify that all end caps and covers on the roof bars are securely in place.
- Remove Accessories: If noise persists, remove any attached accessories (e.g., bike carriers, cargo boxes) to determine if they are the source.
7.3 Scratches or Marks on Vehicle
If you notice marks on your vehicle's paintwork:
- Ensure Cleanliness: Always clean the vehicle's roof and the underside of the fitting kit components before installation. Dirt or grit trapped between surfaces can cause scratches.
- Verify Pads: Ensure all protective rubber pads are correctly installed and are not displaced.
- Check for Movement: A loose fitting kit can rub against the paint. Re-check all fasteners for tightness.
