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.

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.

 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.
