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 2018 INFINITI vehicle can be used for towing and if so it’s towing 
capacity .  
 
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: INFINITI recommends you 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. 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.

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.

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 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. 
  
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.

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.

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.  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 to help ensure against the possibility of a  
serious accident and personal injury or death. 
 
 
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 and to have it installed.

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.
