RENTING
The first thing to keep in mind when renting any type of tow equipment, trailer or 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 do not exceed your vehicle’s 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.
TOWING EQUIPMENT

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.
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- If you have a receiver-type hitch using a ball mount; remove the ball mount
when not towing, or protect it with a special cover, this will help keep 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.

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 are available for a number of weight capacities (3,500 lbs.,
5,000 lbs., etc.), heights, fit different hitch sizes (1 1/4”, 2”, etc.), and can be weight-
distributing or non-weight-distributing. Choose a proper ball mount based on class, hitch
size, weight rating, and the vehicle’s tow capacity.
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 in the ball mount. 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.
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.

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.
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.

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, and damage caused by such modifications
may not be covered under your vehicle’s warranty or may 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. 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.
*When checking or replacement is required, it is recommended you visit an INFINITI retailer for
service.
