2007 Infiniti QX56 Owner's Manual - Page 353

CAUTION ● Special hitches which include frame reinforcements are required for towing above 2,000 lb (907 kg). Suitable genuine INFINITI hitches, ball mounts and hitch balls for pickup trucks and sport utility vehicles are available at an INFINITI dealer. ● The hitch should not be attached to or affect the operation of the impactabsorbing bumper. ● Do not use axle-mounted hitches. ● Do not modify the vehicle exhaust system, brake system, etc. to install a trailer hitch. ● To reduce the possibility of additional damage if your vehicle is struck from the rear, where practical, remove the hitch and/or receiver when not in use. ● Regularly check that all trailer hitch mounting bolts are securely mounted. ● When towing with the hitch ball mounted to the rear bumper, do not make sharp turns. The trailer may contact the bumper and cause damage to the bumper or trailer. Tire pressures ● When towing a trailer, inflate the vehicle tires to the recommended cold tire pressure indicated on the tire placard. ● Trailer tire condition, size, load rating and proper inflation pressure should be in accordance with the trailer and tire manufacturer's specifications. Trailer lights CAUTION When splicing into the vehicle electrical system, a commercially available powertype module/converter must be used to provide power for all trailer lighting. This unit uses the vehicle battery as a direct power source for all trailer lights while using the vehicle tail light, stoplight and turn signal circuits as a signal source. The module/converter must draw no more that 15 milliamps from the stop and tail lamp circuits. Using a module/converter that exceeds these power requirements may damage the vehicle's electrical system. See a reputable trailer dealer to obtain the proper equipment and to have it installed. Trailer lights should comply with federal and/or local regulations. For assistance in hooking up trailer lights, contact an INFINITI dealer or reputable trailer dealer. Vehicles equipped with the optional trailer tow package are equipped with a 7-pin trailer harness connector. If your trailer is equipped with a flat 4-pin connector, an adapter will be needed to connect the trailer lights to the vehicle. Adapters are available at auto parts stores and hitch retailers. Safety chains Always use suitable safety chains between your vehicle and the trailer. The safety chains should be crossed and should be attached to the hitch, not to the vehicle bumper or axle. The safety chains can be attached to the bumper if the hitch ball is mounted to the bumper. Be sure to leave enough slack in the chains to permit turning corners.
