WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
(except supercharger)
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
commended or equivalent ones.

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 on
dry 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 maynot 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 provincial
laws 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.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress. When driv-
ing on clear paved roads, be sure to change
to 2WD.

cluding the spare, and adjust to the speci-
fied pressure if necessary. Check carefully
for damage, cuts or excessive wear.
Wheel nuts*When checking the tires, make
sure no wheel nuts are missing, and check for
any loose wheel nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balanceIf the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Check for
cracks or wear if they do not wipe properly.
Doors, hood and tailgateCheck that the
doors, hood and tailgate operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links as necessary. Make sure that the
secondary latch keeps the hood from open-
ing when the primary latch is released.
When driving in areas using road salt orother corrosive materials, check lubrication
frequently.
Lights*Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.INTERIOR MAINTENANCE
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,

for smooth operation and make sure it has
the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission P (Park) posi-
tion mechanismCheck that the lock re-
lease button on the selector lever operates
properly and smoothly. On a fairly steep hill
check that your vehicle is held securely with
the selector lever in the P position without
applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine oil level*Check the level afterparking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.

for the front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a roof rack, bike car-
rier, or similar equipment does not increase
load carrying capacity of your vehicle.
To determine vehicle load 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.

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, 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
