RENTING 
The first thing to keep in mind when renting a trailer is to rent only from professional companies 
that specialize in towing and towing equipment. More than likely, specialized companies hire 
professional staff that can assist you in selecting and installing the proper towing equipment for 
your Infiniti vehicle. 
 
When renting, make sure you have your vehicle owner’s manual on hand so that you can reference 
the towing capacities for your specific vehicle. Use this data to help select the proper trailer to meet 
your anticipated towing needs.  Never rent a trailer that exceeds the established towing capacities 
for your vehicle, and make sure that any related towing equipment you rent will be sufficient for the 
loaded trailer. 
 
While you are there, ask questions. How much does the empty trailer weigh? How much weight will 
the trailer hold? What is the trailer’s tongue load? With what type of brakes is it equipped (if any)? 
All of these factors have an effect on whether your Infiniti vehicle is capable of safely pulling that 
type of trailer or piece of equipment. 
 
Make certain that the trailer stoplights, taillights, turn signals, and brakes (if equipped) are 
connected and are operating correctly, and that all safety equipment is properly installed. Check 
the safety chains/cables, tie-downs, etc.  
 
For safer operation, carefully inspect the condition of the trailer and towing equipment. Specifically, 
check to make sure the tires are not worn excessively and are properly inflated. Make sure there are 
not any broken welds, missing bolts, and that the hitch components are not damaged.    
 
Towing safety should be a high priority when choosing and renting towing equipment, including 
hitches. NEVER RENT A CLAMP-ON-TYPE HITCH. Your vehicle’s bumpers are not designed for using 
this type of hitch. Using it will damage your vehicle and could even result in the trailer separating 
from the towing vehicle; this can cause death or serious injury. To avoid this, use only a permanent-
type hitch.  
 
PURCHASING 
If you are buying a travel or boat trailer, be sure that your Infiniti vehicle has the towing capacity to 
pull it. Refer to your vehicle owner’s manual for detailed information regarding the towing capacity 
of your specific vehicle. Your vehicle owner’s manual should ALWAYS be referenced before making 
any towing decisions.  
 
Naturally, you will want to select the towing and safety equipment that adheres to your 
state’s and federal safety regulations. 
TOWING EQUIPMENT

Weight-Distributing Hitch System – This type of system 
uses a “load-leveling” or “equalizing” hitch. The weight-
distributing feature helps shift the trailer tongue weight 
to all the axles of the tow vehicle and the trailer axles.   
 
Weight –distributing hitches should be used in many 
towing conditions.  In general, a weight-distributing hitch 
system is recommended and  should be used if you plan 
to tow trailers with a maximum weight over 5,000 lbs.  
Refer to trailer and hitch manufacturer for detailed information on load limits.  Weight distributing 
hitches are available in many styles and with sway control accessory options to accommodate 
trailers with maximum loaded weight and for different driving conditions.  
NOTE – A weight-distributing hitch system may affect the operation of trailer surge brakes. If you are 
considering use of a weight-distributing hitch system with a surge brake-equipped trailer, check 
with the surge brake, hitch, or trailer manufacturer to determine if and how this can be done. Follow 
the instructions provided by the manufacturer for installing and using the weight-distributing hitch 
system. 
 
BALL MOUNT  
A ball mount (also known as a drawbar) is a bar that holds a hitch ball and is inserted into a 
receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000 lbs., etc.) 
and sizes (1 
1/4”, 2”, etc.), and can be weight-distributing or non-weight-distributing.   
 
HITCH BALL 
A hitch ball is bolted through a ball mount or a hitch hole 
in the tow vehicle’s rear bumper. The coupler on the 
trailer tongue attaches over the hitch ball. 
 
Like ball mounts, hitch balls are available in a number of 
weight capacities and sizes. Always make sure the hitch 
ball selected has the proper shank diameter and weight 
rating for the ball mount as well as the coupler on your 
trailer. Using a 1 
7/8” hitch ball in a 2” coupler, for example, could result in the trailer separating 
from the tow vehicle.  
 
The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The shank 
should be no more than 
1/16” smaller than the hole.  To keep the hitch ball in top condition, a 
simple maintenance routine is recommended.  Coating it with light grease will minimize wear of 
both the coupler and hitch ball. Also, by removing the hitch ball when not towing, or by protecting it 
with a special cover, you will help prevent rust from forming on it.

SWAY CONTROL DEVICE 
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.  
Sway control devices may help control these effects. If you choose to use one, contact a reputable 
trailer hitch supplier to make sure the sway control device will work with the vehicle, hitch, trailer 
and the trailer’s brake system. A sway control device is recommended for all towing above 2,000 lb 
(907 kg).  Follow the instructions provided by the manufacturer for installing and using the sway 
control device. 
 
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.  
 
A breakaway switch relies on the power of a trailer battery, so make sure it is not discharged. 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. 
 
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 towing 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 Infiniti vehicles have separate wires for the stoplights and turn signal lights, 
therefore a device called a “converter” is needed.** Specifically, a “powered converter” must be 
used, as a converter of this type creates only minimal additional electrical demand (draw) on the 
vehicle lighting circuits, which helps to ensure 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. 
 
*Vehicles equipped with LED taillights require that wiring be connected at a specific location. For assistance in  
 
 hooking up trailer lights, contact your Infiniti retailer or a professional supplier of towing equipment. 
**QX56 and JX35 vehicles are pre-wired for trailer lighting and do not require a converter.

PASSENGERS 
Never allow passengers to ride inside a trailer while it is being towed. Not only is this unlawful in 
most areas, passengers could be seriously injured during sudden trailer movement or in an 
accident. In addition, trailers may allow fumes from the tow vehicle to leak inside. This could result 
in carbon monoxide poisoning from the engine exhaust. 
 
VEHICLE MODIFICATIONS 
Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, or 
adding extended mirrors — are not recommended for any Infiniti 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 and damage caused by 
such modifications may not be covered under your vehicle’s warranty.  
 
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. 
Be aware that not all automotive jacks can be used safely on a trailer. 
 
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? Is the cargo 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 be inspected. When towing, vehicle engine oil, transmission oil, 
and coolant should always be checked before starting out. Finding a potential problem while in 
your driveway is better than discovering it miles from home.
