PREPARING YOUR VEHICLE 
 
BREAK-IN AND MAINTENANCE SCHEDULE 
 CAUTION- INFINITI recommends that you allow a sufficient âbreak-inâ (500 miles) 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 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 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 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 ownerâs 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 manufacturerâs specifications. 
 
MEASURING VEHICLE WEIGHT 
The key to safer, efficient towing has to do with weight. Your vehicle â SUV, crossover, or 
passenger car â is capable of carrying and towing only a certain amount of weight. You must 
compare your vehicleâs 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 vehicleâs tow 
weight ratings. There are four weights to consider when towing:  
ďˇ Gross Vehicle Weight 
ďˇ Gross Axle Weight (Front and Rear) 
ďˇ Gross Combined Weight 
ďˇ Trailer Tongue Load 
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, 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 could cause a serious accident, personal injury or death.

  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 â whether you are purchasing 
equipment or actually pulling the trailer.  
 
 WARNING- Always make sure your vehicleâs 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 ownerâs 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, âtail wagging,â 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. 
 
â 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.

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, void warranty coverage or 
possible 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. To begin with,
