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.

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 for the towing capacities of 2013 Infiniti vehicles produced at the time of Towing Guide
publication. 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 should influence 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.

Special Note: Do not use your new vehicle to tow a trailer or haul a heavy load for the first 500 miles
(800 km). 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 a trailer 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. Use this data to help select the proper trailer to meet
your anticipated towing needs. Never rent a trailer that exceeds the established towing capacities
for your vehicle, and make sure that any related towing equipment you rent will be sufficient for the
loaded trailer.

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 or piece of 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. Using it will damage your vehicle and could even result in the trailer separating
from the towing vehicle; this can cause death or serious injury. To avoid this, 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 your
state’s and federal safety regulations.
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 equipment you intend to tow. In addition, keep the following in
mind:
Š Do not modify the vehicle’s braking or exhaust systems or its body structure/frame when
installing the hitch.
Š Installing an aftermarket hitch may affect the rear crash performance of your vehicle.
Š Be sure that the hitch does not interfere in any way with the vehicle’s impact-absorbing bumper.
Š Regularly check to see that all hitch-mounting bolts are securely fastened.
Š For receiver-type hitches using a ball mount, the ball mount should be removed when not
towing.
Š 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 LOAD
Trailer tongue load is the amount of
weight pressing down on the tow
vehicle hitch.

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.

Refer to your vehicle owner’s manual to view the maximum trailer tongue load listed for your vehicle.
NOTE – The vehicle weight ratings (GVWR, GAWR, GCWR, etc.) must not be exceeded, regardless of
trailer or hitch type.

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.

Towing can significantly alter the handling and performance characteristics of your vehicle. Plus, 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.

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
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 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.
Excessive trailer tongue load can actually push down the vehicle in back, lifting the front wheels to
a point where traction, steering response, and braking are severely reduced. Insufficient trailer
tongue load or negative load can lift the trailer tongue upwards on the trailer ball causing instability,
which may lead to “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

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 quickly affect
the handling of your vehicle and cause a very
unsafe situation.


Finally, do not carry flammable materials, such as
gasoline, in your trailer. In the event of an accident, an explosion or fire could occur.

ENSURING VEHICLE/TRAILER STABILITY
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.

If swaying does occur, 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 emergency situations.

NOTES












Passenger Vehicles – Infiniti
does not recommend trailer towing with G25, G37 (Coupe, Convertible,
Sedan), M37/M56, or M Hybrid vehicles.

Cross-Over Vehicles – Infiniti
does not recommend trailer towing with EX35, or the FX35 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).
