 2017 NISSAN Towing Guide    17
 
VEHICLE MODIFICATIONS 
 WARNING - DO NOT modify your vehicle beyond those required for proper hitch 
installation, wiring hook-up, or adding extended mirrors on any NISSAN vehicle being used  
for towing purposes. Changes to the drivetrain, suspension, exhaust systems, frame 
structure/unibody, or other vehicle components are not necessary for towing within the limits 
described in this guide. These changes may diminish the reliability and longevity of your 
vehicle, void warranty coverage or possibly result in loss of vehicle control and cause an 
accident, personal injury or death.  
  
TOOL KIT 
When towing, bring tools including,  lugwrench for the trailer wheels, flares, a flashlight, 
emergency reflectors, jumper cables, extra fuses, extra radiator coolant, oil, and easily 
replaced spare parts such as taillight bulbs. You should also carry spare tires for your tow 
vehicle and trailer, as well as a jack suitable for use on the trailer. A trailer jack is an important 
part of safe towing. Choose a jack that can raise and lower the trailer so that you can connect 
the coupler to and disconnect it from the ball of your hitch. Choose one with a weight capacity 
that matches or surpasses your trailer tongue weight.  
 
 WARNING - Be aware that your automotive jack is designed for lifting only your vehicle 
during a tire change. Using an automobile jack to lift a trailer-bearing load may be unstable 
possibly causing it to fall off the jack stand which may result in property damage or serious 
injury or death. 
 
BEFORE STARTING OUT 
Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are 
the tire pressures correct? Are the safety chains/cables securely in place? Has the cargo 
been tied down securely? Do all the lights work? Is the coupler properly attached over the 
hitch ball and secured using a locking pin? Is the breakaway switch hooked up and 
functioning properly? Are vehicle and electric trailer brakes working properly? 
  Make a checklist of key items to inspect. Before towing, always check the tow vehicle’s 
engine oil, transmission oil, and coolant before starting out. Finding a potential problem while 
in your driveway is better than discovering it miles from home.

NOTES – All NISSAN vehicles have an engine protection mode, which helps reduce the 
chance of engine damage if the engine coolant reaches a specified temperature. See your 
vehicle owner’s manual for details. 
 
1  Maximum Trailer Weight values are calculated assuming a base vehicle with driver and any 
options 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 required 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. A 4 or 7-pin type 
connector trailer wire harnesses may be 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. 
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 LIGHT CHECK The system allows you to visually check the trailer brake lights as you cycle 
through them, controlled by the Intelligent Key. 
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.
