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.

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 trailer tongue load listed for your vehicle, and always keep
the tongue load between 10 to 15% of the trailer weight. Do not exceed the 10 to 15% tongue weight
specification. If the calculated tongue weight is less than 10%, reduce the total trailer weight to
match the available tongue weight. DO NOT exceed the maximum tongue load specification.
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 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, as
they may become un-hooked and are 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 mirrors. These mirrors 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.

TRAILER TONGUE LOAD
Trailer tongue load is the amount of
trailer’s weight pressing down on the
tow vehicle hitch ball.
To measure trailer tongue load, place
the tongue of the trailer on a scale
when the trailer is not attached to the
vehicle. A separate vehicle jack — not
the trailer jack — should be used, as
the location of the trailer jack is rearward of the trailer tongue and will not give you an accurate
measurement of the true tongue load. Make sure the vehicle jack is placed directly under the trailer
tongue coupler, and the tongue is set at the height/level of the tow vehicle hitch.
For proper handling, you must keep the trailer tongue load between 10-15% of the actual trailer
weight, within the limits of the maximum trailer tongue load allowable. For example, to determine
the proper trailer tongue load for a 1,500-lb. trailer, multiply the weight of 1,500 lbs. by 10% to arrive
at a figure of 150 lbs.
Some trailer types may require different trailer tongue loads for safe towing. Always follow the
trailer manufacturer’s recommendations for proper trailer set-up and trailer tongue load. Keep the
trailer tongue load within the maximum trailer tongue load allowable. Additionally, make sure the
vehicle has the payload capacity available for the trailer tongue load. If the tongue load becomes
excessive, rearrange cargo to allow for proper tongue load.
Refer to your vehicle owner’s manual to view the maximum trailer tongue load listed for your
vehicle.
HITCH & TRAILER HEIGHT
It is important that your trailer floor and
tongue ride as level as possible. This
will help prevent over-angling, bottoming-out,
and improper tongue load and load transfer.
Therefore, the hitch or trailer tongue must be
adjusted during the initial vehicle/trailer fit-
up to ensure a level ride. Ball mounts and
weight distribution hitches are available in
different configurations to adjust the tongue
load and load transfer and hitch ball height.

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

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.

NOTES
Passenger Vehicles – Infiniti does not recommend trailer towing with Q50, Q60 (Coupe,
Convertible), Q70, or Q70 (HEV) vehicles.
Cross-Over Vehicles – Infiniti
does not recommend trailer towing with QX50, or the QX70 2WD vehicles.
Other Recommendations and Information – Towing performance and speed are affected by vehicle
payload, tow weight, road grades, and weather conditions, including high temperatures. See your
vehicle owner’s manual for details.
1 Maximum Trailer Weight values are calculated assuming a base vehicle with
driver and any options required, to achieve the rating. Additional
passengers, cargo and/or optional equipment will add weight to the vehicle
and reduce your vehicle’s maximum towing capacity and trailer tongue
load.
2 In general, a weight-distributing hitch system should be used when towing
over 5,000 lbs.
3 Most states require a separate braking system on trailers with a loaded
weight above a specific amount. Check local ordinances. 7-pin connector
trailer wire harnesses are required for use with trailer brakes (available
separately).
