●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 buffeting
caused by other vehicles can affect trailer han-
dling. 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.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lb
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lb
(1,588 kg).
CAUTION
● Special hitches which include frame rein-
forcements are required for towing above
2,000 lb (907 kg). Suitable genuine INFINITI
hitches for pickup trucks and sport utility
vehicles are available at an INFINITI retailer.
● 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 dam-
age if your vehicle is struck from the rear,
where practical, remove the hitch and/or re-
ceiver when not in use. After the hitch is
removed, seal the bolt holes to prevent ex-
haust fumes, water or dust from entering the
passenger compartment.
● Regularly check that all trailer hitch mount-
ing bolts are securely mounted.
Tire pressures
●When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire and
Loading Information label.
●Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturers’ specifications.
Safety chains
Always use a suitable chain between your ve-
hicle and the trailer. The safety chains should
be crossed and should be attached to the hitch,
not to the vehicle bumper or axle. The safety
chains can be attached to the bumper if the
hitch ball is mounted to the bumper. Be sure to
leave enough slack in the chains to permit
turning corners.
