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.

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.

GROSS AXLE WEIGHT (GAW)
The Gross Axle Weight (GAW) is the maximum weight placed on a single axle (front
and rear) that it is designed to safely carry.

To determine the GAW, load the vehicle as you would for towing and attach the
loaded trailer. At a public scale, with the loaded trailer attached, place only the tow
vehicle front wheels on the scale to determine the actual front axle GAW. To obtain
the rear axle GAW, place all four tow vehicle wheels on the scale. From that figure,
subtract the front GAW and you will have the rear GAW amount. The cargo in the
trailer and the vehicle may have to be moved, or removed to meet the specified
rating.


The GAW you come up with must not exceed the Gross Axle Weight Rating (GAWR) for
your vehicle. On INFINITI vehicles, the GAWR for both axles is listed on the F.M.V.S.S.
certification label.











GROSS COMBINED WEIGHT (GCW)
The Gross Combined Weight (GCW) is the total weight of the tow vehicle with all
passengers, cargo, and fuel, plus the total weight of the trailer and all its cargo.

To determine the GCW, simply weigh your vehicle when fully loaded and ready to tow,
and add in the weight of the loaded trailer.

in different configurations to adjust the tongue load and load transfer and hitch ball
height. On some tandem axle trailers an incorrect hitch height can result in uneven
trailer axle loading.

WARNING- 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.

WARNING- Always make sure your vehicle’s towing capacity is adequate for the
trailer you intend to tow. Be certain that you have all of the proper equipment needed
for safe towing, such as safety chains/cables, electric trailer brakes, electric trailer
brake controller, breakaway switch, and extended rear view mirrors. Make certain
your equipment conforms to all federal, state or local regulations to help ensure
against the possibility of a serious accident and personal injury or death.

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

WARNING- 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 which could result in
a serious accident, personal injury or death. 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
may be 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
which could result in an accident, personal injury or death.

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.

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.
● 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. Vehicle instability may result in loss of vehicle control and
cause an 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.

2019 INFINITI Towing Guide

To begin with, towing noticeably affects your vehicle’s performance:
 It will not accelerate as quickly — an important point to keep in mind when merging
onto a highway.
 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.
 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 safe, open place with minimal traffic. 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.

WARNING- 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.

WARNING- Entering a sharp corner too quickly or abruptly can “crack the whip,”
whereby the trailer can actually pull the tow vehicle off the road resulting in property
damage, a serious accident, personal injury, or death.

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 rearward vision, have someone
outside the vehicle act as a “spotter” to guide you along.

WARNING- Do not use or rely upon the Back-up Collision Intervention system (BCI)
when towing a trailer. The BCI system cannot function properly when objects are
obstructing the radar sensor beams.

PARK SMART

A tow vehicle and trailer can be an unwieldy combination in a small area, so always
try to park where you will have a relatively easy time maneuvering. Once parked,
always block the wheels on both the tow vehicle and the trailer.

Parking on a slope is not recommended. If, however, you must park on a slope and
your vehicle is equipped with an automatic transmission, there are some precautions
you should take:
 Turn the wheels of the tow vehicle towards the side of the road away from the
center of the road, and apply the parking brake and only then move the gear lever
into PARK.
 Next, block/chock the wheels once the tow vehicle and trailer are in position and
are being held by the vehicle’s brake.

CAUTION-If you move the lever into PARK before blocking the wheels and applying
the parking brake, it may be difficult to later shift out of PARK. Transmission damage
may also occur.

PASS CAREFULLY
As mentioned in the introduction to this section, because of the added weight of the
trailer, acceleration capability is reduced and you will require a longer distance to
pass another vehicle. Be certain you have sufficient time and space to pass safely.


WARNING- Never attempt to pass on hills or when going around curves. Doing so
could cause a loss of vehicle control and result in accident, property damage or
personal injury. Because the trailer does not follow the exact path as the tow vehicle
on turns, safely passing and cornering while towing takes considerably more distance
and turning space than normal. Be certain you have sufficient time and space to pass
safely, remember, the length of the trailer must also pass the other vehicle before you
can safely change lanes.

HILLS – UPGRADES
If your vehicle is equipped with an automatic transmission, it is designed to select
automatically the correct gear for the best towing comfort and performance as the
incline increases. To maintain speed or avoid up and down shifts, manually shift to a
lower gear as needed. The added weight of a trailer places an increased load on the
engine and cooling system, so monitor your coolant temperature gauge and
automatic transmission fluid temperature gauge (if equipped) carefully. At the first sign
of overheating, pull to the side of the road. See IF YOUR ENGINE OVERHEATS later in this
section for more information.
