4. Setup and Installation

Installation is designed to be straightforward. Please follow these steps carefully. A screwdriver is the primary tool required for assembly.

1. Identify Front and Rear Bars: Note that the front cross bar is typically longer than the rear cross bar to accommodate the vehicle's roof curvature. Refer to the included installation manual for specific measurements and identification.
2. Attach Base Feet: Securely attach the four base feet to the cross bars. Ensure the directional labels on the cross bars and bases are correctly aligned for proper orientation.
3. Position Cross Bars: Place the assembled cross bars onto your vehicle's flush side rails. The bases are designed for easy snap-on attachment.
4. Secure Fasteners: Using the provided Allen wrench, tighten all fasteners to secure the cross bars firmly to the side rails. Do not overtighten.
5. Engage Anti-Theft Lock: Once the cross bars are securely installed, use the provided keys to engage the anti-theft locking mechanism on each base. This prevents unauthorized removal and secures the installation.

Reminder: Double-check the package box for the instruction manual and keys, as they may be located at the bottom of the box.

5. Operating Instructions and Safety

5.1 Load Capacity

The HmmtyRack Roof Rack Cross Bars have a maximum load capacity of 300 lbs (136 kg). This capacity is for the cross bars themselves. Always refer to your vehicle's owner's manual for the maximum permissible roof load capacity, and never exceed the lower of the two limits.

5.2 Recommended Cargo

These cross bars are suitable for transporting various items that do not fit inside your vehicle, including:

• Roof bags and cargo boxes
• Bicycles (with appropriate bike carriers)
• Surfboards, kayaks, and canoes (with appropriate watercraft carriers)
• Skis and snowboards (with appropriate ski/snowboard carriers)
• Ladders and other sporting goods

5.3 Safety Precautions

• Secure Cargo: Always ensure all cargo is properly secured to the cross bars using appropriate tie-downs or carriers. Loose cargo can shift during transit, posing a safety hazard.
• Regular Checks: Periodically check the tightness of all fasteners and the security of your cargo, especially during long trips or after driving on rough terrain.
• Driving Habits: Adjust your driving speed and habits when carrying cargo on the roof. Increased wind resistance and a higher center of gravity can affect vehicle handling.
• Clearance: Be mindful of increased vehicle height when entering garages, car washes, or areas with low overhead clearance.
• Sunroof Operation: The design of these cross bars allows for normal operation of your vehicle's sunroof. Non-slip rubber pads are integrated to protect against scratches.

5.4 Aerodynamic Design

The cross bars feature an aerodynamic profile designed to minimize wind noise during travel. While some noise may be present at certain speeds, the design aims to reduce its impact.

6. Maintenance

Proper maintenance will ensure the longevity and continued safe operation of your roof rack cross bars.

• Regular Inspection: Periodically inspect all components for signs of wear, damage, or corrosion. Check that all bolts and fasteners are tight.
• Cleaning: Clean the cross bars with mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish or plastic components. Rinse thoroughly and dry.
• Lubrication: If the locking mechanism becomes stiff, apply a small amount of graphite lubricant to the keyhole.
• Storage: If the cross bars are not in use for an extended period, consider removing them and storing them in a dry, protected area to prolong their lifespan.
