2013 NISSAN Towing Guide 10 NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical
system. Use only a NISSAN approved wiring harness, or consult your dealer or a professional
supplier of towing equipment for compatible equipment.
SWAY CONTROL DEVICE
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer
handling. Sway control devices may be used to 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. Follow the instructions
provided by the manufacturer for installing and using the sway control device.

for your NISSAN vehicle.
BREAK-IN AND MAINTENANCE SCHEDULE
NISSAN recommends that you allow a sufficient “break-in” (500 miles) of both the engine and
drivetrain before towing with your new NISSAN vehicle. In addition, for the first 500 miles that
you tow a trailer, do not drive over 50 mph and do not make starts at full throttle.
Keep in mind, too, that towing places higher demands and added loads on vehicle
components, so more frequent maintenance is called for. Your NISSAN Service &
Maintenance Guide provides the accelerated maintenance schedule for towing purposes.
Engine oil, filter, transmission oil, and possibly other fluids should be changed more frequently

2013 NISSAN Towing Guide 11 MEASURING VEHICLE WEIGHT
The key to safe, efficient towing has to do with weight. Your vehicle — SUV, crossover, truck
or passenger car — is capable of carrying and towing only a certain amount of weight. You
must compare your vehicle’s tow weight ratings with the combined weight of the vehicle,
trailer, and their contents. This will help ensure that the total weight does not exceed any of
your vehicle’s tow weight ratings.
There are four weights to consider when towing:
Š Gross Vehicle Weight
Š Gross Axle Weight (Front and Rear)
Š Gross Combined Weight
Š Trailer Tongue/King Pin Load
These ratings are based upon normal highway driving and may be reduced if operating in
reduced-traction situations, for example, slippery boat ramps.
NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and/or the trailer
tongue/king pin load specified could adversely affect vehicle handling, braking, and
performance. Damage to your vehicle resulting from overloading may not be covered by your
GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo,
fuel, hitch, trailer tongue/king pin load, 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. To that figure, add the combined weight of all passengers.
Then, add the trailer tongue/king pin load to determine the approximate GVW. The GVW you
come up with must not exceed the Gross Vehicle Weight Rating (GVWR) for your
Page 13 of 27
2013 NISSAN Towing Guide 12 On all NISSAN vehicles, the GVWR is shown on the
Federal Motor Vehicle Safety Standard (F.M.V.S.S.)
certification label located in the driver’s-side door area.
To avoid overloading the vehicle, be sure
to include the trailer tongue/king pin load as a
part of the cargo when determining how much weight
can be safely carried inside the vehicle. The weight of
the roof rack cargo should also be included.
GROSS AXLE WEIGHT (GAW)
The Gross Axle Weight (GAW) is the maximum weight each axle (front and rear) 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 GAW you come up with must not exceed the Gross Axle Weight Rating (GAWR)
for your vehicle. On NISSAN vehicles, the GAWR for both axles is listed on the F.M.V.S.S.

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.
The GCW you come up with must not exceed the Gross Combined Weight Rating
(GCWR) for your vehicle. Refer to your vehicle owner’s manual to view the GCWR listed for
TRAILER TONGUE/KING PIN LOAD
The amount of weight pressing down on the tow vehicle hitch is called trailer tongue load
(conventional trailer) or king pin load (5th wheel and gooseneck trailers).
To measure trailer tongue/king pin 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/king pin 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 conventional trailer tongue load between 10-15% of
the actual trailer weight, within the limits of the maximum trailer tongue load allowable.
Page 15 of 27
2013 NISSAN Towing Guide 14 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. 5th wheel and gooseneck trailer
king pin load must be kept between 15-25% of the actual trailer weight, within the limits of
the king pin load allowable.
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 conventional 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 are available in different configurations to adjust the hitch ball height.
When towing a trailer, increase the tow vehicle tire pressures to the recommended cold
specifications. You will find these figures in the vehicle owner’s manual and on the tire
pressure chart located in the vehicle. Trailer tire condition, size, load rating, and inflation
pressure must be in accordance with the trailer and tire manufacturer’s specifications.

2013 NISSAN Towing Guide 15
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
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. King pin load — if using a 5th wheel or gooseneck trailer — must be
between 15-25% of the total trailer weight.
Excessive tongue/king pin 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 tongue/king pin load can cause
instability, which may lead to “tail wagging” or
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/king pin load ratio is achieved.
Page 17 of 27
2013 NISSAN Towing Guide 16 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
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/king pin 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/king pin 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
If the swaying continues and your trailer is suitably balanced and within the towing capacity
limits of your vehicle, discontinue towing and consult your NISSAN dealer or trailer
manufacturer to determine the problem.
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.
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.

2013 NISSAN Towing Guide 17 VEHICLE MODIFICATIONS
Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, or
adding extended mirrors — are not recommended for any NISSAN 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 possibly void warranty coverage.
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
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.
Page 19 of 27
2013 NISSAN Towing Guide 18 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.
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
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. Never attempt to pass
on hills or when going around curves.
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.
When towing a 5th wheel or gooseneck trailer, do not make sharp turns while driving or
backing as the trailer may contact the vehicle and cause damage to both the trailer and
vehicle. A special extended 5th wheel pin box or sliding hitch may be required to provide
additional trailer-to-truck clearance for tight maneuvering.
BACK UP WITH CAUTION
Backing up with a trailer is a difficult maneuver. The best way to steer is by placing one hand
at the bottom of the steering wheel to direct the trailer. The trailer will go in the same direction
Page 20 of 27
2013 NISSAN Towing Guide 19 your hand moves. If you want to turn the trailer to the left, you will turn 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.
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
Š Have someone block the wheels once the tow vehicle and trailer are in position and being
held by the vehicle’s brake.
Š Next, apply the parking brake and only then move the gear lever into PARK. If you move the
lever into PARK before blocking the wheels and applying the parking brake, it may be
difficult later to shift out of PARK. Transmission damage may also occur.
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.
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.
HILLS – UPGRADES
As the incline increases, your vehicle — if equipped with an automatic transmission — is
designed to automatically select the correct gear for the best towing comfort and
performance. To maintain speed or avoid up and down shifts, manually shift to a lower gear as
