Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your ERKUL Heavy Duty Roof Rack Cross Bars. Designed specifically for the Cadillac XT5 (2016-2025 models with fixed holes on roof rails), these aluminum crossbars offer a robust and secure solution for transporting various gear on your vehicle's rooftop. Please read this manual thoroughly before installation and use to ensure proper function and safety.
Safety Information
Always prioritize safety when installing and using roof rack systems. Failure to follow these guidelines may result in property damage, injury, or death.
- Load Capacity: Do not exceed the maximum load capacity of 220 lbs (100 kg) for these crossbars. Always refer to your vehicle's owner's manual for its specific roof load limits.
- Secure Loads: Ensure all cargo is securely fastened to the crossbars using appropriate tie-downs. Check tightness before each trip and periodically during long journeys.
- Weight Distribution: Distribute the load evenly across the crossbars. Avoid placing heavy items solely on one side.
- Vehicle Clearance: Be aware of increased vehicle height when carrying cargo on the roof. Exercise caution in low-clearance areas such as garages, carports, and drive-thrus.
- Driving Conditions: Adjust driving speed and style to account for the added weight and wind resistance. High speeds, sudden braking, or sharp turns can affect vehicle stability.
- Regular Inspection: Periodically inspect the crossbars and mounting hardware for any signs of wear, damage, or looseness. Tighten all fasteners as needed.
- Installation: Follow all installation steps precisely. If unsure, seek professional assistance.

Step-by-Step Instructions:
- Unpack Components: Carefully remove all items from the packaging and verify that all parts listed in the "What's in the Box" section are present.
- Identify Bars: The crossbars may have a designated front and rear, or specific orientation for aerodynamic performance. Refer to the included paper instructions for precise identification.
- Prepare Mounting Points: Locate the fixed mounting points on your vehicle's roof rails. These are typically covered by small caps or flaps that need to be removed.
- Attach Brackets: Assemble the mounting brackets to the crossbars according to the instructions. Ensure the flexible rubber for trim-free t-track installation is correctly positioned.
- Position Crossbars: Carefully place the assembled crossbars onto the fixed mounting points on your roof. Ensure they are aligned correctly and the aerodynamic shape is facing the front of the vehicle.
- Secure Fasteners: Using the provided hardware, tighten all bolts and fasteners to secure the crossbars firmly to the roof rails. Do not overtighten.
- Install Anti-Theft Locks: Once the crossbars are securely mounted, install the lockable anti-theft covers using the provided keys. This will prevent unauthorized removal.
- Final Check: Gently shake the installed crossbars to ensure they are stable and do not wobble. Double-check all connections and locks.

Maintenance
Proper maintenance will extend the life of your ERKUL Roof Rack Cross Bars and ensure continued safe operation.
- Regular Cleaning: Clean the crossbars periodically with mild soap and water. Rinse thoroughly and dry to prevent water spots and corrosion. Avoid abrasive cleaners or solvents.
- Inspect Fasteners: Before each use, and especially after long trips, check all mounting bolts and fasteners for tightness. Re-tighten if necessary.
- Check for Damage: Inspect the aluminum bars, metal brackets, and rubber components for any signs of cracks, bends, corrosion, or excessive wear. Replace any damaged parts immediately.
- Lubrication: If the locking mechanisms become stiff, apply a small amount of graphite lubricant to the keyhole.
- Seasonal Removal: If the crossbars are not used frequently, consider removing them during off-seasons to minimize exposure to harsh weather conditions and reduce potential wind noise.
Troubleshooting
This section addresses common issues you might encounter with your ERKUL Roof Rack Cross Bars.
| Problem | Possible Cause | Solution |
|---|---|---|
| Crossbars feel loose after installation. | Fasteners not tightened sufficiently. | Re-tighten all mounting bolts and fasteners according to the installation instructions. Ensure they are snug but do not overtighten. |
| Excessive wind noise during driving. | Improper installation or aerodynamic components not correctly positioned. | Verify that the crossbars are installed with the correct aerodynamic orientation (if applicable). Ensure all rubber strips and end caps are properly seated. Check for any gaps. |
| Keys do not turn in the lock. | Lock mechanism is stiff or obstructed. | Apply a small amount of graphite lubricant into the keyhole. Gently try to turn the key. Do not force it. |
