TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an optional
trailer tow package. The trailer tow package in-
cludes a receiver-type frame mounted hitch. This
hitch is rated for the maximum towing capacity of
this vehicle when the proper towing equipment is
used. Choose a proper ball mount and hitch ball
that is rated for the trailer to be towed. Genuine
INFINITI ball mounts and hitch balls are available
from your INFINITI dealer.
If your vehicle is not equipped with the optional
trailer tow package, check the towing capacity of
your bumper hitch or receiver-type frame
mounted hitch. Choose a proper hitch for your
vehicle and trailer. A genuine INFINITI trailer hitch
is available from your INFINITI dealer. Make sure
the trailer hitch is securely attached to the vehicle
to help avoid personal injury or property damage
due to sway caused by crosswinds, rough road
surfaces or passing trucks.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause
serious personal injury or property
damage.
Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:● The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.
● Choose the proper class hitch ball based on
the trailer weight.
● The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should
be no more than 1/16” smaller than the hole
in the ball mount.
● The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount and
the ball mount is inserted into the hitch receiver.
Choose a proper class ball mount based on the
trailer weight. Additionally, the ball mount should
be chosen to keep the trailer tongue level with the
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball mount is
one that is designed to carry the whole amount of
tongue weight and gross weight directly on the
ball mount and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling” or
“equalizing” hitch. A set of bars attach to the ball
mount and to the trailer to distribute the tongue
weight (hitch weight) of your trailer. Many vehicles
can’t carry the full tongue weight of a given trailer,
and need some of the tongue weight transferred
through the frame and pushing down on the front
wheels. This gives stability to the tow vehicle.
A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs. Check with the
trailer and towing equipment manufacturers to
determine if they recommend the use of a weight-
distributing hitch system.
