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.
Sway control device
Sudden maneuvers, wind gusts and buffet-
ing caused by other vehicles can affect
trailer handling. Sway control devices may
be used to help control these affects. If you
choose to use one, contact a reputable
trailer hitch supplier to make sure the sway
control device will work with the vehicle,
hitch, trailer and the trailer’s brake system.
Follow the instructions provided by the
manufacturer for installing and using the
sway control device.

ball mount and hitch ball) can be used to
tow trailers of a maximum weight of 2,000
lb (907 kg).

reinforcements are required for towing
above 2,000 lb (907 kg). Suitable
genuine INFINITI hitches for pickup
trucks and sport utility vehicles are

. The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
. Do not use axle-mounted hitches.
. Do not modify the vehicle exhaust
system, brake system, etc. to install a
trailer hitch. .
To reduce the possibility of additional
damage if your vehicle is struck from the
rear, where practical, remove the hitch
and/or receiver when not in use. After
the hitch is removed, seal the bolt holes
to prevent exhaust fumes, water or dust
from entering the passenger compart-
ment.
. Regularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
.When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
.Trailer tire condition, size, loadrating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains

vehicle and the trailer. The safety chains
should be crossed and should be attached
