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. Specialized
companies should 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 at the rental company, 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.
WARNING: NEVER RENT A CLAMP-ON-TYPE HITCH. The hitch should not be attached to or affect
the operation of the impact-absorbing bumper. Use only a permanent-type hitch properly attached
to the vehicle to help avoid personal injury or property damage.
PURCHASING
If you are buying a 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:
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.
Installing an aftermarket hitch may affect the rear crash performance of your vehicle. Changing
the crash performance of a vehicle could lead to more severe vehicle damage, personal injury or
death in a crash. Be sure that the hitch does not interfere in any way with the vehicle’s impact-
absorbing bumper.
Never attach a hitch or towing device to the vehicle bumper. This may affect the operation of the
impact-absorbing bumper. Use only a permanent-type hitch properly attached to the vehicle to
help avoid personal injury or property damage.
Regularly check to see that all hitch-mounting bolts are securely fastened to ensure
the hitch will not come loose, and remains properly attached to the vehicle to help
avoid property damage, personal injury or death.
CAUTION- For receiver-type hitches using a ball mount, the ball mount should be removed when
not towing, or by protecting it with a special cover, this will help protect it from damage, and
prevent rust from forming on it.
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.

Hitch Types
Receiver Hitch – A receiver hitch is bolted directly
to the vehicle structure for added strength and
durability. INFINITI bolt-on receiver hitches are
designed specifically for INFINITI vehicles and
include the necessary reinforcements, with ample
clearance around bumpers, frame members, etc.
These hitches allow for the removal of the ball mount
when not towing. Choose a proper class ball mount
based on the trailer weight.
Clamp-On Bumper Hitch – This is a temporary hitch
that clamps onto the bumper assembly.
WARNING: DO NOT USE this type of clamp-on
bumper hitch on any INFINITI vehicle because using
it may result in the trailer separating from the towing
vehicle. If the trailer separates from the vehicle, it
could cause a crash, resulting in property damage
and personal injury, or death. Use of this type of
hitch can also damage the towing vehicle.
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.

TRAILER TONGUE
The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it also carries
the coupler assembly. Knowledge of the trailer minimum and maximum tongue load is critical as it
can have a significant effect on the handling and capacity of the tow vehicle. Refer to your vehicle
owner’s manual to view the maximum conventional trailer tongue load listed for your vehicle. Trailer
tongue weight is the amount of downward pressure exerted onto the hitch ball. Keep the tongue
load between 10-15% of the total trailer weight. DO NOT exceed the maximum tongue load
specification. If the tongue weight is below the recommended amount, you must move some of the
load forward or add weight to the front frame of the trailer.
SAFETY CHAINS/CABLES
Always use suitable safety chains/cables between the tow vehicle and the trailer. If the hitch
should break or become disengaged for some reason, these chains/cables will provide an
emergency connection between the vehicle and the trailer. The ultimate combined breaking
strength of the two chains must be equal to the gross weight of the towed vehicle(s).
The chains/cables should be crossed under the trailer tongue and attached to the hitch or vehicle
frame. Crossing the chains/cables under the tongue will help prevent the tongue from hitting the
ground should the trailer become disconnected.
Be sure to leave enough slack in the chains/cables to turn corners without binding; however, note
that excessive slack will allow the chains/cables to drag on the ground.
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 INFINITI 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.
“Extended” mirrors specifically designed for trailer towing should be used when your rearward
vision is obstructed. Before using these mirrors, make certain that they comply with state and local
regulations. 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.
Page 8 of 25
2018 INFINITI Towing Guide

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.
WARNING-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. If your vehicle is equipped with a towing package, a 7-pin
trailer harness connector is located at the trailer hitch, under a cover on the rear bumper on some
models for connecting trailer lights. For trailers that use a different style plug, contact your INFINITI
retailer or a professional supplier of towing equipment for adaptors to the 7-pin trailer harness.
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.
CAUTION – Improperly installed or poor quality trailer harness wiring may adversely 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.

PREPARING YOUR VEHICLE
BREAK-IN AND MAINTENANCE SCHEDULE
CAUTION- INFINITI recommends that you allow a sufficient “break-in” (500 miles) of both the
engine and drivetrain before towing with your new INFINITI vehicle. DO NOT tow a trailer or haul a
heavy load for the first 500 miles. For the first 500 miles that that you tow a trailer, do not drive
over 50 mph and do not make starts at full throttle. Following these recommendations helps your
engine and other parts of your vehicle wear in at heavier loads.
Keep in mind, too, that towing places higher demands and added loads on vehicle components, so
more frequent maintenance is called for. Your INFINITI Service & Maintenance Guide provides the
accelerated maintenance schedule for towing purposes. Engine oil, filter, transmission oil, and
possibly other fluids should be changed more frequently when towing.
TIRE PRESSURE
When towing a trailer, increase the tow vehicle tire pressures to the recommended cold
specifications. You will find these figures in the vehicle owner’s manual and on the tire pressure
chart located within the vehicle. Trailer tire condition, size, load rating, and inflation pressure must
be in accordance with the trailer and tire manufacturer’s specifications.
MEASURING VEHICLE WEIGHT
The key to safer, efficient towing has to do with weight. Your vehicle — SUV, crossover, or
passenger car — is capable of carrying and towing only a certain amount of weight. You must
compare your vehicle’s tow weight ratings with the combined weight of the vehicle, trailer, and their
contents. This will help ensure that the total weight does not exceed any of your vehicle’s tow
weight ratings. There are four weights to consider when towing:
Gross Vehicle Weight
Gross Axle Weight (Front and Rear)
Gross Combined Weight
Trailer Tongue Load
These ratings are based upon normal highway driving and may be reduced if operating in reduced-
traction situations (for example, slippery boat ramps).
WARNING- Attempting to tow loads greater than the GVWR, GAWR, GCWR, and the trailer tongue
load specified could adversely affect vehicle handling, braking, and performance. If you do, parts
of your vehicle can break, and tire damage could occur as a result of overloading which may not be
covered by your vehicle warranty. Overloading can also result in loss of control of your vehicle and
which could cause a serious accident, personal injury or death.

WARNING - 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.
WARNING- Always make sure your vehicle’s towing capacity is adequate for the trailer you
intend to tow. Be certain that you have all of the proper equipment needed for safe towing, such
as safety chains/cables, electric trailer brakes, electric trailer brake controller, breakaway switch,
and extended rear view mirrors. Make certain your equipment conforms to all federal, state or local
regulations to help ensure against the possibility of a serious accident and personal injury or death.
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
WARNING- 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 which could result in a serious accident,
personal injury or death. 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 may be 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 which could result in an accident, personal injury or death.
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.
60%40%
TOWING SAFETY
Page 15 of 25
2018 INFINITI Towing Guide

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.
● 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. Vehicle instability may result in loss of vehicle control and cause an
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
WARNING- 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
WARNING - 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, electrical, 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
possible 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.
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? 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.
If you have never towed a trailer before, be aware that it does take getting used to. To begin with,
