- Weight Capacity: While designed for strength, avoid excessive or concentrated weight on the step pads. Refer to the specifications for maximum recommended load.
- Safety: Always exercise caution when using the step, especially in wet or icy conditions. The non-skid pads are designed to reduce slippage, but vigilance is always recommended.
6. Care and Maintenance
To maintain the polished finish and ensure the longevity of your ARIES Nerf Bars, follow these care instructions:
- Regular Cleaning: Clean the stainless steel surfaces regularly with mild soap and water. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Polishing: For optimal shine, use a non-abrasive stainless steel cleaner or polish periodically. Follow the product instructions for application.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, steel wool, or harsh chemicals, as these can scratch the polished finish or damage the step pads.
- Inspect Hardware: Periodically check all mounting hardware for tightness. Re-tighten as necessary to ensure the bars remain securely attached to the vehicle.
- Step Pad Condition: Inspect the non-skid step pads for any signs of wear or damage. Replace if necessary to maintain safe footing.
7. Troubleshooting
Should you encounter any issues with your ARIES Nerf Bars, consider the following common solutions:
- Loose Nerf Bar: If the nerf bar feels loose or wobbly, check all mounting bolts and ensure they are tightened to the recommended torque specifications. Over time, vibrations can cause bolts to loosen.
- Squeaking/Rattling: This may indicate loose hardware or contact between components. Inspect all mounting points and ensure no parts are rubbing against the vehicle's body or frame.
- Corrosion/Stains: While made of corrosion-resistant stainless steel, prolonged exposure to harsh elements or certain chemicals can cause surface discoloration. Clean immediately with appropriate stainless steel cleaner. For stubborn stains, consult a professional automotive detailer.
- Damaged Step Pad: If a step pad is cracked or worn, it may need replacement to ensure safe use. Contact ARIES customer support for replacement parts.
If problems persist after attempting these solutions, please contact ARIES customer support for further assistance.
