2015 NISSAN Towing Guide 22 1 Maximum Trailer Weight values are calculated assuming a base vehicle with driver and any
options required to achieve the rating. Additional passengers, cargo and/or additional
optional equipment will add weight to the vehicle and reduce your vehicle’s maximum
towing capacity and trailer tongue load.
2 Use of a weight-distributing hitch system is re when towing over 5,000 lbs.
3 The Maximum Trailer Weight and Gross Combined Weight ratings for 5th wheel and
gooseneck trailer towing are the same as specified for conventional trailer towing.
4 Most states require a separate braking system on trailers with a loaded weight above a
specific amount. Check local regulations where you plan to tow. 7-pin connector trailer
wire harnesses are required for use with trailer brakes (available separately).
Other Recommendations and Information – Towing performance and speed are affected by
vehicle payload, tow weight, road grades, and weather conditions, including high
temperatures. See your vehicle owner’s manual for details.
TOWING
GLOSSARY
5TH WHEEL
HITCH Located just forward of the rear axle centerline, this hitch uses a king pin to
serve as the pivot point for the trailer.
BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver. Also
commonly called a drawbar.
BREAKAWAY SWITCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if the trailer accidentally becomes separated from the tow vehicle.
A breakaway switch may be used with both electric or surge trailer brake
systems.
BUMPER HITCH A reinforced bumper designed to accommodate a hitch ball.
ELECTRIC TRAILER
BRAKES When the brakes on a tow vehicle are applied, an electric current is sent to
an actuator, which applies the trailer’s brakes.
ELECTRIC TRAILER
BRAKE CONTROLLER A device that controls the electric trailer brakes.
GOOSENECK HITCH Located just forward of the rear axle centerline, this hitch uses a ball to serve
as the pivot point for the trailer.
GROSS AXLE
WEIGHT RATING (GAWR) The maximum amount of weight each vehicle axle (front and rear) is
designed to safely carry.
GROSS COMBINED
WEIGHT RATING (GCWR) The maximum allowable combined weight of the vehicle and trailer,
including passengers and all cargo.
GROSS VEHICLE
WEIGHT RATING (GVWR) The maximum allowable weight of the vehicle, including passengers, cargo,
fuel, hitch, trailer tongue load, and any optional equipment.
KING PIN
LOAD The amount of trailer (5th wheel or gooseneck) weight pressing down on the
tow vehicle hitch.
2015 NISSAN Towing Guide 23
HITCH BALL
A ball that connects the trailer to the tow vehicle hitch that provides the
means by which the trailer pivots during cornering. Available in a number
of sizes and weight capacities, it must correspond to the trailer coupler
size, and have a sufficient capacity rating for the trailer being pulled.
RECEIVER HITCH A frame- or structure-mounted hitch with a receiver that allows removal of
the ball mount.
SAFETY CHAINS/CABLES Provides an emergency connection between the tow vehicle and the trailer,
should the trailer become disengaged for any reason.
SURGE BRAKES
Hydraulic-type braking system activated by inertia. As the tow vehicle
begins to brake, the trailer pushes against the hitch ball, consequently
activating the trailer brakes.
TRAILER TONGUE/COUPLER The part of the trailer that extends forward to meet the tow vehicle, and
carries the coupler assembly.
TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the tow
vehicle hitch.
WEIGHT-DISTRIBUTING
HITCH SYSTEM Type of hitch system that helps shift the trailer tongue weight to all trailer
tires and the tow vehicle front tires. Strongly recommended when towing
trailers with a Maximum Trailer Weight greater than 5,000 lbs.
WIRING HARNESS Provides an electrical connection linking the tow vehicle’s electrical system
to the trailer’s system.
