SAFETY IS PRIORITY ONE 
Obviously, your first concern should be safety. Your vehicle was designed to be used primarily to 
carry passengers and cargo. Always remember that towing a trailer places additional loads on your 
vehicle’s engine, drivetrain, suspension, steering, braking, and other systems. Therefore, be certain 
that your vehicle can meet the demands of the towing application you have in mind. 
 
Rent or purchase only the highest-quality towing and safety equipment you can find. Reinforced tow 
hitches designed especially for certain Infiniti vehicles are available from your Infiniti retailer. 
Hitches for other Infiniti models — if Infiniti recommends towing with that vehicle — should be 
bought from and installed by a professional supplier of towing equipment.  Carefully review all 
information and literature provided with any hitch you purchase for safety and proper use 
information. Finally, it is important to follow the towing capacity limit set for your specific vehicle 
and to ensure that your vehicle is in top mechanical condition, especially the tires, brakes, 
suspension, and engine cooling system. See your vehicle owner’s manual for details. 
 
NEVER EXCEED THE ESTABLISHED TOWING CAPACITY 
Towing capacities vary from vehicle to vehicle. See the towing information in your vehicle owner’s 
manual to confirm whether your 2014 Infiniti vehicle can be used for towing and if so it’s towing 
capacity . Use this data to help select the proper Infiniti vehicle to meet your anticipated towing 
needs, and refer to it when towing, renting a trailer or other piece of towing equipment.  
 
EQUIP YOUR INFINITI FOR TOWING 
The frequency and type of towing dictate the manner in which you equip your vehicle. If you plan to 
tow often, either for recreation or work, select the engine size, transmission type, suspension, and 
towing capacity that are best suited to your requirements. This guide can help you select the proper 
equipment.  
 
 READ THIS GUIDE BEFORE YOU TOW 
This guide was designed to provide an overview of safe towing practices. Here, you will find 
information on towing equipment, safety, proper loading and driving techniques, towing tips, and 
much more. 
 
It is also a good idea to discuss your towing requirements with either your Infiniti retailer or a 
professional supplier of towing equipment before you equip your Infiniti vehicle for towing. 
Finally, there are state and local laws on towing that you should review to ensure compliance with 
all regulations. 
 
CAUTION: Do not use your new vehicle to tow a trailer or haul a heavy load for the first 500 miles 
(800 km) of use.  Your engine, axle or other parts could be damaged.  For the first 500 miles that 
you tow a trailer, do not drive over 50 mph and do not make starts at full throttle. This helps your 
engine and other parts of your vehicle wear in at heavier loads.

RENTING 
The first thing to keep in mind when renting any type of tow equipment, trailer, tow dolly, 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. Make certain that the tow equipment and 
components you rent not exceed your maximum towing capacity. Make sure that any related towing 
equipment you rent has the proper weight class rating for your maximum intended towed load 
weight, and the maximum Gross Combined Weight Rating. 
 
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, dolly, or piece of tow 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. 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 federal safety 
regulations, as well as any regulations in any state in which you may travel. 
TOWING EQUIPMENT

And if you plan to tow often, consider convenience. Quick-disconnect trailer light connectors and 
ratchet-type tie-downs, for example, make the job go faster and easier and are usually worth the 
extra small investment. Purchase towing items such as hitches and hitch balls only from your 
Infiniti retailer or a professional supplier of towing equipment. 
 
If you are intending to use your vehicle to tow a trailer you already own, you must ensure that your 
loaded trailer remains well within your vehicle's towing capacity as specified in the vehicle owner's 
manual. In addition, you should purchase the right type, style, and class* of hitch and towing 
equipment to properly adapt the trailer to your vehicle. 
 
 
 
 
 
TYPES OF EQUIPMENT 
Towing requires a variety of equipment, and, depending upon the application, there can be several 
types or styles of each piece of equipment. Working with your Infiniti retailer or a professional 
supplier of towing equipment, it should be relatively simple to determine the proper type of 
equipment for your specific vehicle given the intended application. This section explains the most 
common pieces of towing equipment available.  
 
HITCHES 
Whichever type of hitch you use, it should be firmly bolted to your vehicle, and should be of the 
appropriate weight class for the trailer, tow dollies or towing equipment you intend to tow. In 
addition, keep the following in mind: 
 Š WARNING- Never modify the vehicle’s braking or exhaust systems or its body structure/frame 
when installing the hitch.  Altering the brakes or structure on a vehicle could increase the 
likelihood of a crash.  
 Š WARNING- Installing an aftermarket hitch may affect the rear crash performance of your  vehicle. 
Be sure that the hitch does not interfere in any way with the vehicle’s impact-absorbing bumper.  
 Š CAUTION- Regularly check to see that all hitch-mounting bolts are securely fastened.  Not 
following this could cause damage to the vehicle or its components. 
 Š For receiver-type hitches using a ball mount, the ball mount should be removed when not 
towing. 
 Š CAUTION- If you install a hitch yourself, remember that it must be securely attached to the frame 
or underbody, according to the manufacturer’s instructions. Never attach a hitch or towing 
device to the vehicle axle housing. This may damage the housing, wheel bearings, wheels, or 
tires.

WHAT IS RIGHT FOR YOU

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.  Choose a 
proper class ball mount based on the trailer weight. 
 
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 required hitch 
ball size is stamped on most trailer couplers.  
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.

Telescoping Tow Mirrors are available as an accessory for certain Infiniti vehicles. Contact your 
Infiniti retailer for details. 
 
SWAY CONTROL DEVICE 
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.  
Sway control devices may help control the pivoting motion between tow vehicle and trailer and 
make trailer towing easier on the driver. 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).   Too low a percentage of tongue weight can also cause sway.   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. 
**QX80 and QX60 vehicles are pre-wired for trailer lighting and do not require a converter.

NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 
Use only an Infiniti approved wiring harness, or consult your retailer or a professional supplier of 
towing equipment for compatible equipment.  
 
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. 
WARNING- Never connect a trailer brake system directly to the vehicle brake system.  Trailer brakes 
must be connected so that in the case of a breakaway from the towing vehicle, the trailer brakes system 
shall automatically apply to stop the trailer.  
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, Infiniti 
recommends the installation of a trailer brake controller.  If you use an all-electronic actuation 
system it will not be necessary to tap into the tow vehicle’s hydraulic system.  For adjustment 
specifications refer to the brake controller manual for the controller being used.  
For your convenience, QX80 and QX60 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 Infiniti retailer.  This harness provides electric trailer brake controller input and output 
connections to the vehicle wiring. Contact an Infiniti retailer or a professional supplier of towing 
equipment for information on trailers equipped with electric brakes and for Genuine Infiniti jumper 
harness availability for your specific vehicle. 
 
CAUTION- Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 
Use only an Infiniti approved wiring harness, or consult your retailer or professional supplier of 
towing equipment for compatible equipment.  
 
GENUINE INFINITI PARTS AND ACCESSORIES 
Whether you will be towing occasionally or on a regular basis, Infiniti offers a full range of Genuine 
Infiniti Parts and Accessories to help you tow with confidence. Every accessory is thoroughly tested 
and inspected for fit and workmanship. Therefore, you can be certain that every item is designed to 
be compatible with the standard features of your vehicle and designed to assist you with your 
towing needs. 
*Contact your Infiniti retailer for more information on accessories or towing-related parts for your 
Infiniti vehicle.

CAUTION- Towing can significantly alter the handling and performance characteristics of your 
vehicle. Moreover, it puts increased strain on the engine and drivetrain. Therefore, it is always a 
good idea to approach towing from the standpoint of safety — whether you are purchasing 
equipment or actually pulling the trailer.  
 
CAUTION- Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to 
tow. Buy or lease only quality equipment. In addition, be certain that you have all of the equipment 
needed for safe towing, such as safety chains/cables, electric trailer brakes, electric trailer brake 
controller, breakaway switch, and extended rear view mirrors.  
 
You should follow a more frequent maintenance schedule and check fluid levels, pressures, tire 
condition, etc., more often when on the road. See your vehicle owner’s manual for details. 
 
LOADING YOUR TRAILER 
CAUTION- Taking the time to load and balance your trailer properly will improve overall handling 
and minimize the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing from 
side to side, upsetting vehicle handling. Careful loading and balancing, and a weight distribution 
hitch and sway-control device can help eliminate these problems. 
 
As mentioned earlier, conventional trailer tongue load must fall between 10-15% of the total trailer 
weight, or within the limits of the maximum trailer tongue load specified by the trailer 
manufacturer. WARNING- Excessive trailer tongue load can actually push down the tow vehicle in 
back, lifting the front wheels to a point where traction, steering response, and braking are severely 
reduced which could result in an accident, personal injury or death. Too little trailer tongue load or 
negative load can lift the trailer tongue upwards on the trailer ball causing instability, which may 
lead to swaying, “tail wagging,” or jackknifing. 
 
With this in mind, proper loading is extremely 
important. When loading a trailer, 60% of the total 
cargo weight should be positioned in the front 
portion of the trailer and 40% in the back. Then the 
load should be adjusted until the proper tongue load 
ratio is achieved.

TOWING SAFETY  
Page 15 of 25

 2014 Infiniti Towing Guide  
 14 
WARNING-The trailer load should be balanced 
equally from side-to-side. Unequal side-to-side 
loading can negatively affect handling and 
braking. Once in place, all cargo should be firmly 
secured to prevent shifting. If the load should shift 
abruptly during braking or cornering, it could 
adversely affect the handling of your vehicle and 
cause a very unsafe situation and may lead to an 
accident or personal injury. 
 
 
WARNING- DO NOT carry flammable materials, such as gasoline, in your trailer. In the event of an 
accident, an explosion or fire could occur. 
 
PROVIDING FOR VEHICLE/TRAILER STABILITY 
WARNING- Improper loading, excessive or insufficient trailer tongue load, overloading, excessive 
trailer weight, poorly designed trailer suspensions, crosswinds, and poor maintenance are all 
things that can affect the stability of your vehicle and trailer combination.  Overloading or unsafe 
operating conditions could lead to a serious accident, personal injury or death. 
 
If swaying occurs, gradually reduce speed, and apply only the trailer brakes to help reduce sway.  
Steady the steering wheel and gradually  pull over and stop to check the cargo load for proper 
balance and distribution to ensure proper trailer tongue load. In addition, check the condition of 
the suspension and shocks, as well as the tires, tire pressures, and wheel bearings on both the tow 
vehicle and trailer.  
 
If the swaying continues and your trailer is suitably balanced and within the towing capacity limits 
of your vehicle, discontinue towing and consult your Infiniti retailer or trailer manufacturer to 
determine the problem.  
 
VEHICLE SPEED 
Please note that some states have specific regulations and speed limits for vehicles that are towing 
trailers.  Remember to reduce your speed in unsafe or less-than-ideal road conditions or weather. 
When towing a trailer, braking distances increase while handling agility decreases. Always leave 
yourself an extra margin of distance to respond to emergencies.

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 
DO NOT modify your vehicle beyond those required for proper hitch installation, wiring hook-up, or 
adding extended mirrors on 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. 
CAUTION- 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 inspect. 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.
