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 of 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. Do not
exceed maximum speed suggested by the
chain manufacturer. Otherwise, your ve-
hicle may be damaged and/or vehicle han-
dling and performance may be adversely
affected.
Never install tire chains on T-type and small
size spare tires. Do not use tire chains on
dry roads.
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
Tighten wheel nuts to 72 to 87 ft-lb (98 to
118 Nzm).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
WARNING
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the lug nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
cDo not include the T-type spare tire
or any other small size spare tire in
the tire rotation.

ing any brakes.
UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically, for example, each
time you check the engine oil or refuel.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself section'' of this manual.
Windshield washer fluid* ÐCheck that
there is adequate fluid in the reservoir.
Engine coolant level*Ð Check the cool-
ant level when the engine is cold.
Radiator and hosesÐ Check the front ofthe 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.
Brake fluid level*Ð Make sure the brake
fluid level is between the MIN and MAX
lines on the reservoir.
Battery*Ð Check the fluid level in each
cell. It should be between the MAX and MIN
lines.
Engine drive belts*Ð Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*Ð Check the level after
parking the vehicle on a level surface with

ately have the exhaust system inspected by
an authorized NISSAN dealer. See the car-
bon monoxide warning in the ``Starting and
driving'' section of this manual.
UnderbodyÐ The 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 leaksÐ Check 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 by
an authorized NISSAN dealer.

WARNING
cIt is extremely dangerous to ride in a
cargo area inside of a vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
cDo not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
c
Be sure everyone in your vehicle is in
a seat and using a seat belt properly.
Terms
It is important to familiarize yourself with the
following terms before loading your vehicle:
cCurb Weight (actual weight of your ve-
hicle) - vehicle weight including: standard
and optional equipment, fluids, emer-
gency tools, and spare tire assembly.
This weightdoes notinclude passen-
gers and cargo.
cGVW (Gross Vehicle Weight) - curb
weight plus the combined weight of pas-
sengers and cargo.
cGVWR (Gross Vehicle Weight Rating) -maximum total weight (load) limit speci-
fied for the vehicle.
cGAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified for
the front or rear axle.
cGross combined weight - GVW plus the
total weight of the trailer and all its cargo.
Determining Vehicle Load Capacity
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a luggage rack, bike
carrier, cartop carrier 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 vehicle.
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 & passengers), re-weigh your vehicle to determine if either
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.
Loading Tips
cThe GVW must not exceed GVWR or
GAWR specified on the F.M.V.S.S. Cer-
tification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
c
Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWRs. 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.
