BRAKES
As with hitc hes, several types of braking systems are available. Most states require a
separate braking system on t railers 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
b rakes 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 runnin g 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 tr ailer
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, Q X80 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 reta iler
or professional supplier of towing equipment for compatible equipment and to have
it installed.

GENUINE INFINITI PARTS AND ACCESSORIES

PREPARING YOUR VEHICLE
BREAK-IN AND MAINTENANCE SCHEDULE
CAUTION- INFINITI recommends that you allow a su fficient “break-in” 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 50 0 miles. For the first 500 miles
that you tow a trail er, do not drive over 50 mph and do not make starts at full throttle .
F ollowing 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 ve hicle
components, so more frequent maintenance is called for. Your INFINITI S ervice &
Maintenance G uide provides the accelerated maintenance schedule for towing
purposes. Engine oil, filter, transmission oil, and possibly other fluids should be changed
mor e frequently when towing.

TIRE PRESSURE
When towing a trailer, increase the tow vehicle tire pressures to the recommended
cold specifications . You wi ll find these figures in the vehicle owner’s manual and on the
tire pressure chart located with in 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. Y our vehicle — SUV, or
crossover vehicle — is capable of carrying and towing only a certain amount of
weight. You must compare your vehicle’s tow weight rating s with the combined
weight of the vehicle, trailer , and their contents. This will help ensure that the total
weight doe s not exceed any of your vehicle’s tow weight rating s. There are four
weights to consider when towing:
 Gross Vehicle Weight - curb weight of vehicle plus the combined weight of
passengers and cargo
 Gross Axle Weight (Front and Rear)- maximum weight (load limit) that can be
specified for front or rear axle
 Gross Combined Weight- maximum total weight of vehicle, passengers, cargo,
and trailer
 Trailer Tongue Load - the weight exerted at the vehicle- trailer coupling point

These ratings are based upon normal high way 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 t railer tongue l oad 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 c ould cause a
serious accident, personal injury or death.

GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the actual weight of the fully loaded vehicle or
trailer , including passengers, cargo , and fuel, hitch, trailer tongue weight , and any
optional equipment.

The best way to determine the GVW is by having
the vehicle — loaded and ready to tow —
weighed at a public scale. That figure must
include the combined weight of all passengers
and cargo that are normally in the vehicle when
towing a trailer .

The GVW of the towing vehicle must not exceed
the G ross Vehicle Weight Rating (G VWR) shown
on t he Federal Motor Vehicle Safety Standard
(F .M .V .S .S./C.M.V.S.S. ) certification label located
in the driver’s -side door area. Weigh your veh icle
on a platform type scale with all of the
passengers and cargo that are normally in the
vehicle when towing a trailer. Subtract the actual
vehicle weight from the GVWR. The remaining
amount is the available maximum tongue/king
pin load.

To avoid over loading the vehicle, be sure to
include the trailer tongue weight as a part of the
cargo when determining how much weight can
be safely carried inside the vehicle. The weight of
any roof rack cargo should also be included.






F.M.V.S.S Certification Label

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 t he 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 G ross Axle Weight Rating (GAWR) for
your vehicle . On INFINITI vehicles , the GAWR f or 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 al l 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.

The GCW you come up with must not exceed the Gross Combined Weight Rating
(GCWR) for your vehicle . R efer to yo ur vehicle owner’s manual to view the maximum \
GCWR specification listed for your vehicle.


TRAILER TONGUE LOAD
Trailer t ongue 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 meas urement 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 allow able.
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, th e
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 tr ansfer and hitch ball
he ight . 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 a re 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 o f 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 caus ing instability, which may lead to swaying, “tail wagging ,” or jackknif ing
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.





TOWING SAFETY

2020 INFINITI Towing Guide

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 carg o should be firmly
secured to prevent shifting. I f 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
anaccident or personal injury .
● D O N OT carry flammable materials, such as
gasoline, in your t railer. In the event of an
a ccident, an explosion or fire could occur.

PROVIDING FOR VEHICLE/TRAILER STABILITY

WARNING - Improper loading, excessive or in sufficient trailer tongue load,
overloading, excessive trailer weight, po orly 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 loa d 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.

I f the swaying contin ues and your trailer is suitably balanced and within the towing
capacity limits of your vehicle, discontinue towing and consult your INFINITI retailer or
trailer m anufacturer to determine the problem.

VEHICLE SPEED
Please note that s ome states have speci fic 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 emergenc ies.

PASSENGERS

WARNING - Never allow passengers to ride inside a trailer while it is being towed.
Not only is this unlawful in m ost areas, passengers could be seriously injured during
sudden t railer 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

WARNING - DO NOT modify your vehicle beyond those required for proper hitch
installation, wiring hook -up , or adding extended mirrors on any INFINITI vehicle being
used for towing purposes. Changes to the drivetrain, suspension, exhaust systems,
electrical, frame structure/un ibody, 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 , void warranty coverage or possible result in loss
of vehicle control and ca use an accident, personal injury or death.


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. Choose a jack that can raise and lower the
trailer so that you can connect the coupler to and disconnect it from the ball of your
hitch. Choose on e with a weight capacity that matches or surpasses your trailer
tongue weight.

WARNING- Be aware that your automotive jack is designed for lifting only your
vehicle during a tire change. Using an automobile jack to lift a tr ailer-bearing load may
be unstable possibly causing it to fall off the jack stand which may result in property
damage or serious injury or death.

BEFORE STARTING OUT
Before starting out on a trip, make one last inspection of the tow vehicle and the traile r.
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 inspect . When towing, vehicle engine oil, transmission
oil, and coolant should always be checked before starting out. Finding a poten tial
problem while in your driveway is better than discovering it miles from home.
If you ha ve never towed a trailer before, be aware that it does take getting used to.
