2. Safety Information

Adherence to these safety guidelines is crucial for preventing accidents and ensuring the longevity of your roof bars and vehicle.

• Maximum Load Capacity: Never exceed the maximum load capacity specified for your vehicle's roof or the roof bars (whichever is lower). Refer to your vehicle's owner's manual for specific load limits.
• Secure Fastening: Always ensure that the roof bars and any attached cargo are securely fastened before driving. Check all fasteners regularly, especially after driving short distances or on rough roads.
• Weight Distribution: Distribute cargo evenly on the roof bars to maintain vehicle stability. Avoid placing heavy items on one side.
• Driving Speed: Adjust your driving speed according to the load and road conditions. High speeds with roof-mounted cargo can affect vehicle handling and fuel consumption.
• Height Clearance: Be aware of the increased height of your vehicle with roof bars and cargo, especially when entering garages, car washes, or low-clearance areas.
• Regular Inspection: Periodically inspect the roof bars for any signs of wear, damage, or loose components. Replace damaged parts immediately.
• Installation: Ensure correct installation as per this manual. Incorrect installation can lead to detachment of the roof bars or cargo.

4. Setup and Installation

The NORDRIVE N15056 roof bars are designed for vehicles equipped with solid, closed roof rails. Ensure your vehicle has this type of rail before proceeding.

4.1 Identify Compatible Roof Rails

Figure 2: Example of a closed roof rail. This image shows a vehicle's roof with a flush, integrated roof rail, indicated by an arrow and the text "CLOSED RAIL".

Figure 3: Compatibility for solid roof rails. This image clarifies that the roof bars are "ONLY FOR USE ON VEHICLES WITH SOLID ROOF RAILS (AS ILLUSTRATED HERE)", showing a vehicle with raised, solid roof rails.

The roof bars attach to solid roof rails that run along the length of your vehicle's roof. These rails are typically integrated or have a gap underneath for clamping mechanisms. The N15056 model is specifically designed for solid rails, as shown in Figures 2 and 3.

4.2 Assembly of Roof Bars

1. Unpack all components and verify against the package contents list.
2. Identify the aluminum profiles and the four mounting feet.
3. Slide the mounting feet onto the aluminum profiles. The feet are adjustable to accommodate different vehicle roof rail widths.
4. Insert the rubber profile into the upper T-slot channel of the aluminum bar. This seals the channel after accessories are mounted.
5. Attach the end caps to the ends of the aluminum profiles.

Figure 4: Roof bar dimensions and components. This diagram illustrates the overall dimensions of the assembled roof bar, including the height (91 mm), the width of the mounting foot (100 mm), and the adjustable length ranges (S=75-103 cm, M=99-115 cm, L=106-122 cm). The image shows the aluminum bar, mounting feet, and end caps.

4.3 Mounting on Vehicle Roof Rails

1. Place the assembled roof bars onto your vehicle's roof rails.
2. Adjust the position of the mounting feet along the aluminum profile to align with your vehicle's roof rail width.
3. Secure the mounting feet to the vehicle's roof rails using the provided power grip fastening mechanism. Ensure a tight and secure fit. Refer to the specific instructions provided with the hardware for tightening torque if available.
4. Ensure both roof bars are parallel and evenly spaced on the roof.
5. Double-check all connections for tightness before driving.

5. Operating Instructions

Once installed, the NORDRIVE N15056 roof bars are ready for use with compatible roof accessories (e.g., bike racks, ski carriers, roof boxes) that utilize the T-slot system or clamp around the bar profile.

• Loading Cargo: When loading items, distribute the weight as evenly as possible. Place heavier items towards the center of the vehicle.
• Securing Cargo: Always use appropriate straps, nets, or locking mechanisms to secure cargo to the roof bars. Ensure there is no movement or shifting of cargo during transit.
• Aerodynamics: Large or irregularly shaped cargo can significantly affect vehicle aerodynamics and fuel efficiency. Consider using aerodynamic roof boxes for optimal performance.
• Regular Checks: During long journeys, periodically stop and check the security of your cargo and the roof bar attachments.

6. Maintenance

Proper maintenance ensures the longevity and safe operation of your roof bars.

• Cleaning: Clean the aluminum profiles and plastic components with mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish.
• Inspection: Regularly inspect all bolts, clamps, and moving parts for signs of corrosion, wear, or damage. Ensure all components are tight.
• Lubrication: If any moving parts become stiff, apply a small amount of silicone-based lubricant.
• Storage: If not in use for extended periods, consider removing the roof bars and storing them in a dry, protected area to prevent unnecessary wear and exposure to elements.

7. Troubleshooting

This section addresses common issues you might encounter.

• Roof bars feel loose after installation: Re-check all fastening points. Ensure the power grip mechanism is fully engaged and tightened according to instructions. If the issue persists, consult a professional.
• Excessive wind noise: Ensure all end caps are securely in place and the rubber profile is properly seated in the T-slot. Adjusting the position of the front bar slightly can sometimes reduce noise.
• Difficulty attaching accessories: Ensure the T-slot connectors of your accessories are compatible with the 28mm height and 49.5mm width profile of the NORDRIVE N15056 bars.
