ommended or equivalent ones.

LOAD1,000 (454)

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and trailer.
A genuine NISSAN trailer hitch is available from
your NISSAN dealer (Canada only) . Make sure
the trailer hitch is securely attached to the ve-
hicle, to help avoid personal injury or property
damage due to sway caused by crosswinds,
rough road surfaces or passing trucks.
Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:
cThe required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.cChoose the proper class hitch ball based on
the trailer weight.
cThe 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.
cThe 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.
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 (909 kg) .
You may add Class I trailer hitch equipment that
has a 2,000 lb (909 kg) maximum weight rating to
the vehicle, but your vehicle is only capable of
towing the maximum trailer weights shown in the
Towing Load/Specification Chart earlier in this
section.
CAUTION
cDo not use axle-mounted hitches.cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.
cTo 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.
cAfter the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
cTrailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
