5. Setup (Installation Instructions)
Professional installation is recommended. If performing self-installation, ensure you have the necessary tools and follow these steps carefully. Installation typically takes approximately one hour.
5.1 Pre-Installation Checklist
- Verify vehicle compatibility: Ensure your vehicle is a Toyota Land Cruiser LC250 Prado J250 model (2024-2026).
- Confirm all package contents are present and undamaged.
- Gather necessary tools (e.g., wrenches, sockets, torque wrench).
5.2 Installation Steps
- Identify Mounting Points: Locate the factory mounting points on the vehicle's chassis beneath the doors. These are typically pre-drilled holes.
- Attach Brackets: Secure the appropriate mounting brackets to the vehicle's frame. Note that brackets 1 and 3 may be interchangeable for either side, but bracket 2 is side-specific (left or right). Align the bolts to the rail before tightening.
- Position Running Board: Carefully lift and position the running board onto the attached brackets.
- Secure Running Board: Fasten the running board to the brackets using the provided hardware. The rails typically have two slots underneath for securing; however, often only the slot closest to the vehicle is used for optimal fit and security.
- Tighten Hardware: Hand-tighten all bolts first, then progressively tighten them to the manufacturer's recommended torque specifications. Ensure all connections are secure.
- Repeat for Other Side: Follow the same steps for installing the running board on the opposite side of the vehicle.
- Final Inspection: After installation, perform a thorough inspection to ensure all components are securely fastened and the running boards are stable.

- Stepping On: Use the running board as a stable step to assist in entering or exiting your vehicle. Place your foot firmly on the anti-slip surface.
- Weight Distribution: Distribute your weight evenly when stepping onto the board. Avoid placing excessive weight on one small area.
- Cleaning: The running boards also help to keep your vehicle's interior cleaner by allowing occupants to wipe off dirt and debris from their shoes before entering.

7. Maintenance
Regular maintenance will ensure the longevity and optimal performance of your running boards.
- Cleaning: Clean the running boards regularly with mild soap and water to remove dirt, mud, and road grime. Avoid abrasive cleaners or harsh chemicals that could damage the finish or anti-slip pad.
- Inspection: Periodically inspect all mounting hardware (bolts, nuts, brackets) for tightness. Re-tighten any loose fasteners to prevent rattling or instability.
- Damage Check: Check the running boards for any signs of damage, such as cracks, bends, or excessive wear on the anti-slip surface. Replace damaged components if necessary.
