Installation Instructions (Setup)

No extra drilling is required if your vehicle has existing mounting holes. Follow these steps for installation:

1. Prepare the Vehicle: Park the vehicle on a flat, stable surface. Engage the parking brake.
2. Identify Mounting Points: Locate the factory mounting holes on the vehicle's frame. These are typically found along the rocker panel.
3. Attach Brackets: Align and loosely fasten the mounting brackets to the vehicle's frame using the supplied bolts and nuts. Do not fully tighten at this stage.
4. Install Running Boards: Carefully position the running board onto the attached brackets. Ensure proper alignment.
5. Secure Running Boards: Fasten the running board to the brackets using the remaining hardware.
6. Adjust and Tighten: Adjust the running board for desired position and levelness. Once satisfied, fully tighten all bolts to the specified torque (refer to your vehicle's owner's manual for specific torque values if available, or consult a professional).
7. Final Check: Check door clearance and test the stability of the step. Ensure all connections are secure.

Operating Instructions

The running boards are designed for easy entry and exit from your vehicle. Step onto the polymer pads for a secure foothold. The 3-inch injection-molded polymer step pads have undergone extensive testing to ensure durability and structural integrity, providing a reliable step surface.

Maintenance

To ensure the longevity and appearance of your YHTAUTO running boards, follow these maintenance guidelines:

• Regular Cleaning: Clean the running boards regularly with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the semi-gloss black powder coating.
• Inspection: Periodically inspect all mounting hardware (bolts, nuts, brackets) for tightness. Re-tighten any loose fasteners to prevent rattling or instability.
• Damage Check: Check for any signs of rust, corrosion, or physical damage to the running boards or mounting components. Address any issues promptly to prevent further deterioration.
• Polymer Pads: Ensure the polymer step pads are free from excessive dirt or debris that could reduce traction.

Troubleshooting

If you encounter any issues with your running boards, refer to the following common problems and solutions:

• Loose Running Board: If the running board feels loose or wobbly, inspect all mounting bolts and nuts. Tighten them securely.
• Rattling Noise: A rattling noise often indicates loose hardware. Re-check and tighten all fasteners. Ensure no components are rubbing against the vehicle's body.
• Corrosion/Rust: While designed for resistance, prolonged exposure to harsh conditions without proper cleaning can lead to corrosion. Clean affected areas and apply a protective coating if necessary. For significant rust, consider professional repair or replacement.
• Difficulty Stepping: Ensure the step pads are clean and free of obstructions. If the step height is an issue, verify correct installation and vehicle compatibility.
