BALL MOUNT
A ball mount (also known as a drawbar) is a bar that holds a hitch ball and is inserted into a
receiver-type hitch. Ball mounts are available for a number of weight capacities (3,500 lbs.,
5,000 lbs., etc.), heights, fit different hitch sizes (1 1/4”, 2”, etc.), and can be weight-
distributing or non-weight-distributing. Choose a proper ball mount based on class, hitch
size, weight rating, and the vehicle’s tow capacity.


HITCH BALL
A hitch ball is bolted through a ball mount or a hitch
hole in the tow vehicle’s rear bumper. The coupler on
the trailer tongue attaches over the hitch ball.
Like ball mounts, hitch balls are available in a
number of weight capacities and sizes. Always make
sure the hitch ball selected has the proper shank
diameter and weight rating for the ball mount as
well as the coupler on your trailer. Using a 1 7/8”
hitch ball in a 2” coupler, for example, could result in the trailer separating from the tow
vehicle. The required hitch ball size is stamped on most trailer couplers.
The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The
shank should be no more than 1/16” smaller than the hole in the ball mount. To keep the
hitch ball in top condition, a simple maintenance routine is recommended. Coating it with
light grease will minimize wear of both the coupler and hitch ball. Also, by removing the
hitch ball when not towing, or by protecting it with a special cover, you will help prevent
rust from forming on it.

TRAILER TONGUE
The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it
also carries the coupler assembly. Knowledge of the trailer minimum and maximum tongue
load is critical as it can have a significant effect on the handling and capacity of the tow
vehicle. Refer to your vehicle owner’s manual to view the maximum conventional trailer
tongue load listed for your vehicle. Trailer tongue weight is the amount of downward
pressure exerted onto the hitch ball. Keep the tongue load between 10-15% of the total
trailer weight. DO NOT exceed the maximum tongue load specification. If the tongue
weight is below the recommended amount, you must move some of the load forward or
add weight to the front frame of the trailer.

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.

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.

if the vehicle is equipped with a front passenger air bag. Children 12 and under should
ride in the rear seat properly secured in child restraints, booster seats, or seat belts,
according to their size. Please see your vehicle owner's manual for more details.
