tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maxi-

All season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ``ALL SEASON'' and/or ``M&S'' on
the tire sidewall. Snow tires have better
snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance ondry roads. Summer tire performance in
snow and ice will be substantially reduced.
Summer tires do not have the tire traction
rating ``M&S'' on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' or ``ALL SEASON'' tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
States and Canadian provinces prohibit
their use. Check local, state and provinciallaws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or undercarriage. If possible, avoid fully
loading your vehicle when using tire chains.
In addition, drive at a reduced speed. Oth-
erwise, your vehicle may be damaged
and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.

for the front or rear axle.
DETERMINING VEHICLE PAY-
LOAD CAPACITY
The payload capacity of this vehicle is de-
termined by weight, not by available cargo
space. For example, a roof rack, bike car-
rier, or similar equipment does not increase
payload carrying capacity of your vehicle.
To determine vehicle payload capacity:
Vehicle weight can be determined by using
a commercial-grade scale, found at places
such as a truck stop, gravel quarry, grain
elevator, or a scrap metal recycling facility.
1) Determine the curb weight of your ve-
hicle.
2) Compare the curb weight amount to the
GVWR specified for your vehicle to de-
termine how much more weight your
vehicle can carry.3) After loading (cargo and passengers),
reweigh your vehicle to determine if ei-
ther GVWR or GAWR for your vehicle is
exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
SECURING THE LOAD
For your convenience, tie down hooks are
placed at each corner of the truck box.
These may be used to help secure cargo
loaded into the truck box.
WARNING
cProperly secure all cargo with ropes
or straps to help prevent it from
sliding or shifting. Do not place
cargo higher than the seat backs. In
a sudden stop or collision, unse-
cured cargo could cause personal
injury.
ATI1020
9-16Technical and consumer information

cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWR's. If you do,
parts on your vehicle can break, tire
damage could occur, or it can
change the way your vehicle
handles. This could result in loss of
control and cause personal injury.
CAUTION
Overloading can shorten the life of your
vehicle. Failures caused by overloading
are not covered by your warranty.
LOADING TIPS
cThe GVW must not exceed GVWR or
GAWR as specified on the FMVSS Cer-
tification Label located on the driver's
door jamb pillar.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the
GVWR.
cLoads should be spread out, and cargo
should be properly secured. Large or
heavy objects should be placed towardthe front of the truck box to help prevent
sliding or shifting.
Crew Cab models:
Crew Cab models should not be used to
carry a slide-in camper.
Regular and King Cab models:
This information is provided for you to prop-
erly install a slide-in camper and is based on
the National Highway Traffic Safety Admin-
istration regulations. It is recommended
that, before installing the camper, you care-
fully read the following information and en-
sure that the camper meets the specifica-
tions.
This information may not apply to some
Canada model vehicles.
Special body vehicles
Some vehicles are equipped with commer-
cial or camper bodies. However, this Own-
er's Manual does not cover these options.
For further information, please refer to the
body manufacturer's instruction manual.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the truck camper is loaded, drive to a
scale and weigh the front and the rear
wheels separately to determine axle loads.
Individual axle loads should not exceed
either of the gross axle weight ratings
(GAWR). The total of the axle loads should
not exceed the gross vehicle weight rating
(GVWR). These ratings are given on the
vehicle certification label that is located on
the driver's door lock pillar. If weight ratings
are exceeded, move or remove items to
bring all weights below the ratings.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer will place
additional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
ANissan Trailer Towing Guideis avail-
able from an authorized NISSAN dealer.
This guide includes information on trailer
towing ability and the special equipment
required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart. The total trailer
load equals trailer weight plus its cargo
weight.
cWhen towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake
system MUST be used.
The maximum GCWR (Gross Combined
Weight Rating) should not exceed the value
specified in the following Towing Load/
Specification Chart.
The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect
vehicle handling, braking and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced on very

TOWING A TRAILER
Technical and consumer information9-21
ZX

TOWING SAFETY
Trailer hitch
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 Nissan trailer hitch is
available from your NISSAN 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.
CAUTION
cSpecial hitches which include frame
reinforcements are required for tow-
ing above 2,000 lb (907 kg). Suitable
genuine NISSAN hitches for pickup
trucks and sport utility vehicles are
available at an authorized NISSAN
dealer.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use. Remove receiver
when not in use. After the hitch is
removed, seal the bolt holes to pre-
vent exhaust fumes, water or dust
from entering the passenger com-
partment.
cRegularly check that all trailer hitch
mounting bolts are securely
mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (af-
fixed to the inside of the glove box lid).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chain
Always use suitable safety chains between
your vehicle and the trailer. Safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. Be sure to leave enough slack in the
chain to permit turning corners.
Trailer lights
Trailer lights should comply with Federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an autho-
rized NISSAN dealer.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
