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.

PREPARING YOUR VEHICLE  
BREAK-IN AND MAINTENANCE SCHEDULE  
  CAUTION- INFINITI recommends that you allow a sufficient “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 500 miles. For the first 500 miles 
that you tow a trailer, do not drive over 50 mph and do not make starts at full throttle.   
Following 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 vehicle 
components, so more frequent maintenance is called for. Your INFINITI Owner’s 
Manual & Maintenance Guide provides the accelerated maintenance schedule for 
towing purposes. Engine oil, filter, transmission oil, and possibly other fluids should be 
changed more frequently when towing. 
 
TIRE PRESSURE 
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 within 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. Your 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 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: 
 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 highway 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 trailer tongue load specified could adversely affect vehicle handling, stability, 
braking, and performance.  Parts of your vehicle can break, and tire damage could 
occur as a result of overloading; this may not be covered by your vehicle warranty.  
Overloading can also result in loss of control of your vehicle and which could 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 Gross Vehicle Weight Rating (GVWR) shown 
on the 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 vehicle 
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 overloading 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.

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.

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 maximum  
GCWR specification listed for your vehicle.
  
 
TRAILER TONGUE LOAD 
Trailer tongue load is the amount 
of the 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 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.   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, 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.  On some tandem axle trailers an incorrect hitch height can result in uneven 
trailer axle loading. 
 
  WARNING- Towing can significantly alter the handling, stability 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 avoid 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. Refer to your vehicle 
owner’s manual for details.  It is recommended you visit an INFINITI retailer for service. 
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 and stability 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 and 
stability 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, it may result in an explosion, fire,  
or personal injury or death. 
 
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.

PASSENGERS 
 
 WARNING- 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 
 
  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/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 or may possibly result in loss of 
vehicle control and cause 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 one 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 trailer-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 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 inspect. 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.  
*When checking or replacement is required, it is recommended you visit an INFINITI retailer for       
service.
