Pre-towing tips ● Be certain your vehicle maintains a level position when a loaded and/or unloaded trailer is hitched. Do not drive the vehicle if it has an abnormal nose-up or nose-down condition; check for improper tongue load, overload, worn suspension or other possible causes of either condition. ● Always secure items in the trailer to prevent load shift while driving. ● Keep the cargo load as low as possible in the trailer to keep the trailer center of gravity low. ● Load the trailer so approximately 60% of the trailer load is in the front half and 40% is in the back half. Also make sure the load is balanced side to side. ● Check your hitch, trailer tire pressure, vehicle tire pressure, trailer light operation, and trailer wheel lug nuts every time you attach a trailer to the vehicle. ● Be certain your rearview mirrors conform to all federal, state or local regulations. If not, install any mirrors required for towing before driving the vehicle. LTI0116 4. Peel off the tape and connect the jumper harness to the connector 2 . 5. Release the parking brake. 6.
