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

2013 Infiniti Towing Guide
5
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.

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 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. 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.

SWAY CONTROL DEVICE
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.
Sway control devices may help control these effects. 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). 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.

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. 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.
**QX56 and JX35 vehicles are pre-wired for trailer lighting and do not require a converter.

NOTE – 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 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. Have a professional supplier of towing equipment
demonstrate proper brake function testing.
NOTE – Never connect a hydraulic trailer brake system directly to the vehicle hydraulic brake system.

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 all-electronic actuation because with this
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, QX56 and JX35 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.
NOTE – 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.

GENUINE INFINITI PARTS AND ACCESSORIES

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

2013 Infiniti Towing Guide

PASSENGERS
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
Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, or
adding extended mirrors — are not recommended for any Infiniti vehicle being used for towing
purposes. Changes to the drivetrain, suspension, exhaust systems, 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.

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.
Be aware that not all automotive jacks can be used safely on a trailer.

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 be inspected. 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,
towing noticeably affects your vehicle’s performance:
Š It will not accelerate as quickly — an important point to keep in mind when merging onto a
highway.
Š It will not stop as quickly. Leave more room than usual between you and the traffic ahead, and
brake sooner when coming to a stop.
Š Abrupt maneuvering can unbalance the load and reduce the handling and stability of your tow
vehicle. Plan ahead and make lane changes and turns smoothly.

If possible, before you actually hit the open road, practice towing in a large uncrowded area such as
a stadium or shopping center parking lot. Become especially familiar with backing up a trailer — the
maneuver many people find most difficult.

BRAKE SOONER
The combination of your tow vehicle and trailer obviously requires a greater distance to stop. A
good rule of thumb to remember is that for each 10 mph of speed, allow yourself one tow vehicle
and trailer length of distance between the front of your vehicle and the vehicle ahead.

When braking, use firm but gradual pressure on the pedal rather than panic braking. Applying the
brakes abruptly or with too much force can cause the trailer to skid or jackknife at its point of
attachment with the vehicle. This, in turn, can throw the tow vehicle out of control. If equipped with
an electric trailer brake controller, follow the recommended operational instructions.

CORNER MORE SLOWLY
Know your vehicle and trailer capabilities. Entering a sharp corner too quickly or abruptly can “crack
the whip,” whereby the trailer can actually pull the tow vehicle off the road. Therefore, when
approaching a relatively sharp corner, begin braking sooner than you would when not towing. Do
your braking in a straight line prior to the corner, and turn smoothly into it. In addition, remember to
make a wider turn than normal to ensure that the trailer safely clears the inside of the turn.

BACK UP WITH CAUTION
Backing up with a trailer is a difficult maneuver. Steer with one hand at the bottom of the steering
wheel. To turn the trailer to the left, first move the steering wheel to the left. To turn the trailer to the
right, move the wheel to the right. All movements of the wheel should be done in small increments.
Of course, backing up should be done only at very slow speeds. For large trailers that obstruct your

your vehicle is equipped with Tow Mode, see your vehicle owner’s manual for information about the
use of this function.

Avoid long or repeated use of the brakes when descending a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a lower gear instead provides “engine braking” and
reduces the need to brake as frequently.

HIGH-ALTITUDE PERFORMANCE
An engine will lose about 4% of its performance for every 1,000 feet above sea level that you travel.
If you will be towing in high altitudes, it is a good idea to allow more time than usual due to the
engine’s reduced performance.

AUTOMATIC CRUISE CONTROL
Do not use cruise control while towing a trailer.

BLIND SPOT INTERVENTION
Do not use the Blind Spot Intervention system (BSI) when towing a trailer.

TOW MODE (IF EQUIPPED)
Tow Mode is recommended when towing a heavy trailer or hauling a heavy load, in stop-and-go
traffic, rolling terrain, or a busy parking lot. Driving the vehicle in Tow Mode may affect fuel
economy and transmission/engine driving characteristics. See your vehicle owner’s manual for
additional information about Tow Mode.

IF YOUR ENGINE OVERHEATS
A moderate increase in engine operating temperature is normal when towing a trailer. If, however,
the coolant temperature gauge reading is abnormally high, or if you are experiencing a significant
loss of power, or if you hear unusual engine noises,* the engine may be overheating and you
should immediately take the following steps:

1. Pull your vehicle safely over to the side of the road, out of traffic. Apply the parking brake
and move the gearshift lever to NEUTRAL (manual) or PARK (automatic). DO NOT STOP THE
ENGINE.

2. Turn off the air conditioning and, after opening all the windows, turn the heater on to

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).
