converter" must be used to provide power for all trailer lighting. This type of converter creates only minimal additional electrical demand (draw) on the vehicle lighting circuits, which provides protection for the vehicle's sensitive electronics. Always check for correct operation of the taillights, stoplights, and turn signal lights every time you connect a trailer for towing. Never replace vehicle fuses with fuses of a higher amperage rating than the original. CAUTION - Improperly installed or poor quality trailer harness wiring may adversely affect your vehicle's electrical system. Use only a NISSAN approved wiring harness, or, consult your dealer or a professional supplier of towing equipment to obtain the proper equipment and to have it installed. BRAKES As with hitches, several types of braking systems are available. Most states require a separate braking system on trailers with a loaded weight above a specific amount, therefore you should check to ensure you comply with all regulations and laws. Have a professional supplier of towing equipment demonstrate proper brake function testing. Never connect a trailer brake system directly to the vehicle brake system. Most states require a separate braking system on trailers with a loaded weight of 1,500 lbs. (680 kg) or more. Surge Brakes - The surge brake actuator is mounted on the trailer tongue with a hydraulic line running to each trailer wheel. Surge brakes are activated by the trailer pushing against the hitch ball when the tow vehicle is braking. Hydraulic surge brakes are common on rental trailers and some boat trailers. In this type of system, there is no hydraulic or electric connection for brake operation between the tow vehicle and the trailer. Electric Trailer Brakes - Electric braking systems are activated by an electronic signal sent from a trailer brake controller (special brake-sensing module). If electric trailer brakes are used, NISSAN recommends the installation of an aftermarket trailer brake controller. For adjustment specifications, refer to the manufacturer's instructions of the brake controller being installed. For your convenience, Armada, Frontier, Pathfinder, Titan, and NV vehicles are prewired to accommodate most popular electric trailer brake controllers. A wiring harness* is either included with your vehicle or available from your NISSAN dealer. This harness provides electric trailer brake controller input and output connections to the vehicle wiring. See a professional supplier of towing equipment for electric trailer brake controller availability. * Contact a NISSAN dealer or a professional supplier of towing equipment for information on trailers equipped with electric brakes and for Genuine NISSAN jumper harness availability for your specific vehicle. 2015 NISSAN Towing Guide 9
