4. Operating Instructions

Once installed, your CURT trailer hitch and wiring harness enable your Toyota Camry to tow a trailer. Always adhere to safe towing practices and never exceed the vehicle's or hitch's towing capacities.

4.1. Towing Capacity

• Maximum Gross Trailer Weight (GTW): 2,500 lbs
• Maximum Tongue Weight (TW): 250 lbs

Important: Always consult your vehicle's owner's manual for its specific towing capacity. Never exceed the lowest rated component in your towing system (vehicle, hitch, or trailer).

4.2. Safe Towing Practices

• Ensure the trailer is properly loaded with approximately 10-15% of the trailer's weight on the tongue.
• Connect the trailer to the hitch receiver using a properly sized ball mount and hitch ball.
• Attach safety chains from the trailer to the vehicle's hitch safety chain loops.
• Connect the trailer's electrical plug to the vehicle's wiring harness connector.
• Verify all trailer lights are working before each trip.
• Drive at reduced speeds and allow for increased braking distances when towing.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your CURT trailer hitch and wiring harness.

• Hitch Inspection: Periodically inspect the hitch for any signs of rust, damage, or loose fasteners. Tighten any loose bolts to the specified torque.
• Wiring Inspection: Check the wiring harness for frayed wires, damaged connectors, or corrosion. Clean electrical contacts with a suitable electrical contact cleaner if necessary.
• Receiver Tube: Keep the inside of the receiver tube clean and free of debris. Apply a light coat of grease to the hitch ball shank to prevent rust and ease coupling.
• Storage: If not in use for extended periods, consider removing the ball mount and storing it in a dry place.

6. Troubleshooting

If you encounter issues with your trailer lights, follow these basic troubleshooting steps. The CURT T-Connector Wiring Harness features a circuit-protected converter system to prevent damage to your vehicle's electrical system.

If trailer lamps are not working but the vehicle lamps are:

• Shut power off to the faulted circuit.
• Correct the overload condition (e.g., too many bulbs).
• Restore power to the circuit.

If trailer lamps work for a few seconds and then go off:

1. Check the ground wire on both the harness and trailer.
2. Check and correct an overload condition (too many bulbs).

If the circuit fails to light:

1. Check tow vehicle fuses.
2. Check all electrical connections.
3. Check the trailer lamp bulbs.
4. Check the ground wire on both the harness and trailer.
5. Locate and correct a short.

Note: Using a tester such as CURT catalog number 58206 can help confirm system function.

If problems persist, see your installer for corrective action. Always check trailer lights before towing.
