5. Operation
Once the CURT trailer hitch is securely installed, it is ready for towing. Always ensure that the trailer being towed does not exceed the lowest-rated towing component, which includes the hitch's capacity, the vehicle's towing capacity, and the trailer's Gross Vehicle Weight Rating (GVWR).
Towing Best Practices:
- Connect Securely: Always use a properly sized hitch ball and ensure the coupler is fully engaged and locked onto the hitch ball.
- Safety Chains: Cross safety chains under the trailer tongue and attach them to the designated chain loops on the hitch.
- Wiring: Connect trailer lighting wiring harness to the vehicle's electrical system for proper signal lights and brakes.
- Weight Distribution: Distribute the trailer load evenly, ensuring proper tongue weight (typically 10-15% of the GTW for conventional trailers).
- Pre-Trip Inspection: Before each trip, inspect the hitch, ball, coupler, safety chains, and wiring for any signs of wear, damage, or improper connection.
6. Maintenance
Regular maintenance of your CURT trailer hitch will ensure its longevity and safe operation.
- Inspect Regularly: Periodically check the hitch for any signs of rust, chipping, cracks, or deformation. Pay close attention to weld points and mounting hardware.
- Clean: Keep the hitch clean from dirt, salt, and road debris. Wash with mild soap and water, then rinse thoroughly.
- Protect Finish: The dual-coat finish provides excellent protection. If any deep scratches or chips occur, touch up with a suitable rust-inhibiting paint to prevent corrosion.
- Hardware Check: Ensure all bolts and nuts remain tight. Re-torque if necessary according to the original installation instructions.

7. Troubleshooting
While CURT hitches are designed for reliability, occasional issues may arise. Here are some common concerns and general advice:
- Fitment Issues: If the hitch does not seem to align correctly with your vehicle's frame, double-check that you have the correct model for your specific Mercedes-Benz GLK350 year and trim. Ensure all obstructions are removed as per the detailed installation guide.
- Loose Components/Noise: If you notice rattling or excessive movement, inspect all mounting hardware. Tighten any loose bolts to the specified torque settings. Ensure the hitch ball and coupler are properly secured.
- Corrosion: Despite the protective coating, prolonged exposure to harsh elements or damage to the finish can lead to rust. Address any chips or scratches promptly with rust-inhibiting paint.
- Towing Performance: If experiencing sway or instability while towing, verify that the trailer is loaded correctly with appropriate tongue weight. Ensure tire pressures on both the vehicle and trailer are correct.
For persistent issues or complex installation challenges, it is recommended to consult a certified professional installer or contact CURT customer support directly.
