  WARNING- Do not use S-hooks for attaching the safety chains as they may become un-
hooked while towing.  If the S-hook unhooks, the emergency chains/cables will become 
detached,  so if the tow hitch breaks or becomes disengaged, it will allow the trailer to 
completely break away causing property damage and possibly personal injury or death.   
The use of S-hooks is illegal in many states.  
 CAUTION- To avoid damage to the bumper and chains/cables when making a sharp turn, 
do not attach the chains/cables too close to the coupler. Consult your trailer manufacturer for 
the proper location of the chain/cable attachment to the trailer. 
 
REAR VIEW MIRRORS 
 WARNING- In many cases, a trailer can block your rear vision when you are using only the 
standard NISSAN rear view  and outside mirrors. Be careful when changing lanes or turning.  
Using only these mirrors could cause an accident as they were not designed for towing. 
 
 
Trailer tow mirrors specifically designed for trailer towing can be adjusted for better visibility 
when your rearward vision is obstructed while towing a trailer. Trailer Tow Mirrors are available 
as an accessory for certain Nissan vehicles.  Before using these mirrors, make certain that 
they comply with state and local regulations.  It is recommended you contact your NISSAN 
dealer for details. 
 
BREAKAWAY SWITCH 
On a trailer with electric brakes, a breakaway switch can automatically activate the trailer 
brake system if the trailer becomes separated from the tow vehicle. Should the trailer become 
detached, a breakaway switch may help prevent the trailer from wandering into another lane. 
  
 WARNING-A breakaway switch relies on the power of a trailer battery, so make sure to 
maintain the battery’s charge.  Never use the breakaway switch to “park” the trailer on a 
grade. The battery would eventually discharge and release the brake, allowing the trailer to 
roll, which may cause property damage, serious injury or death.  Be sure to leave enough 
slack in the tether on the breakaway switch to turn corners without binding. If you do not, the 
electric trailer brakes will lock-up and not release. See your trailer manufacturer for proper 
installation of a breakaway switch that is compatible with your trailer braking system. 
 
TRAILER LIGHTS 
Trailer lights should comply with all applicable federal, state, and local regulations, and should 
be in proper working order at all times. A trailer’s taillights, stoplights, and turn signal lights 
must be wired into the tow vehicle’s electrical system.*  
Most trailers operate on a four-wire system in which the stoplights and turn signal lights 
utilize the same wire. Most all NISSAN vehicles have separate wires for the stoplights and turn 
signal lights, therefore a device called a “converter” is needed.** Specifically, a “powered  
  *  Vehicles equipped with LED taillights require that wiring be connected at a specific location. For  
assistance in hooking up trailer lights, contact your NISSAN dealer or a professional supplier of towing equipment. 
**  Armada, Frontier, Pathfinder, and Titan, vehicles are pre-wired for trailer lighting and do not require a converter.  
If your trailer is equipped with a 4-pin connector, an adapter will be needed to connect the trailer lights to the 
vehicle.  Vehicles equipped with the optional trailer tow package can be equipped with a 7-pin trailer harness 
connector.

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 equivalent, 
and 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 
and the vehicle is not equipped with an integrated trailer brake controller, 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 pre-wired 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.

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,  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.
