Before driving, make sure your vehicle and trailer maintenance is current. This is very important because towing puts additional stress on the tow vehicle. (Review the next section of the brochure for an overview of maintenance requirements.)

• Check and correct tire pressure on the tow vehicle and trailer.
• Make sure the trailer wheel lug nuts/bolts on the tow vehicle and trailer are tightened to the correct torque.
• Be sure the trailer hitch part, coupler trailer part, draw bar trailer part, and other equipment that connect the trailer and the tow vehicle are properly secured and adjusted.
• Check that the trailer wiring is properly connected—not touching the road, but loose enough to make turns without disconnecting or damaging the wires.
• Make sure all running lights, trailer brake lights, trailer turn signal lights, and hazard lights are working.
• Verify that the brakes on the tow vehicle and trailer are operating correctly.
• Check that all items are securely fastened on and in the trailer.
• Be sure the trailer jack, tongue support, and any attached trailer stabilizers are raised and locked in place.
• Check load distribution to make sure the tow vehicle and trailer are properly balanced front to back and side to side.
• Check side- and rear-view mirrors to make sure you have good visibility.
• Check routes and restrictions on bridges and tunnels.
• Make sure you have wheel chocks and jack stands.
