Types of tires
CAUTION
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. Your NISSAN dealer may
be able to help you with information
about tire type, size, speed rating and
availability. Replacement tires may
have a lower speed rating than the
factory equipped tires, and may not
match the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
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 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.
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 prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-stalling studded tires. Skid and traction ca-
pabilities 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 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 underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.

Tire rotation*Ð Tires should be rotated
every 7,500 miles (12,000 km).
Wheel alignment and balanceÐIfthe
vehicle should pull to either side while driv-
ing 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*Ð Check for
cracks or wear if they do not wipe properly.
Doors and engine hoodÐ Check that all
doors and the engine hood operate prop-
erly. Also ensure all latches lock securely.
Lubricate hinges, latches, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when
the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*Ð Make sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.INSIDE THE VEHICLE
The maintenance items listed here should
be checked on a regular basis, such as

that the wipers and washer operate properly
and that the wipers do not streak.
Windshield defrosterÐ Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelÐ Check for changes in
the steering conditions, such as excessive
freeplay, hard steering or strange noises.
SeatsÐ Check seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and that the locks (if so
equipped) hold securely in all latched posi-
tions.Seat beltsÐ Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Accelerator pedalÐ Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mats away from the pedal.
Clutch pedal*Ð Make sure the pedal
operates smoothly and check that it has the
proper free travel.
BrakesÐ Check that the brakes do not pull
the vehicle to one side when applied.
Brake pedal*Ð Check the pedal for
smooth operation and make sure it has the
proper distance under it when depressed
fully. Check the brake booster function. Be
certain to keep floor mats away from the
pedal.

UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the items
marked with ª*º can be found in the
ªDo-It-Yourself operationsº section.
Windshield washer fluid*Ð Check that
there is adequate fluid in the tank.
Engine coolant level*Ð Check the cool-
ant level when the engine is cold.
Radiator and hosesÐ Check 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.
Brake and clutch fluid levels*Ð Make
sure that the brake and clutch fluid level is
between the ``MAX'' and ``MIN'' 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 that no
belt is frayed, worn, cracked or oily.
Engine oil level*Ð Check the level after
parking the vehicle on a level spot and
turning off the engine.
Power steering fluid level* and linesÐ
Check the level when the fluid is cold and
the engine is turned off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level*Ð
Check the level after putting the shift lever in
``P'' with the engine idling.
Exhaust systemÐ Make sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section.)
UnderbodyÐ The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. Itis very important to remove these sub-
stances, otherwise rust will form on the floor
pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. See the ``Appearance and interior
care'' section for additional information.
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.

VEHICLE LOADING INFORMATION
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.
Determining Vehicle Load Capacity
The load capacity of this vehicle is determined
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 and 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 as specified on the FMVSS Cer-
tification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
CAUTION
c
Properly secure all cargo to help pre-
vent it from sliding or shifting. In a
sudden stop or collision, unsecured
cargo could cause personal 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.
cOverloading can shorten the life of
your vehicle. Failures caused by
overloading are not covered by your
warranty.

Trailer hitch
Choose a proper hitch for your vehicle and
trailer. Make sure the trailer hitch is securely
attached to the vehicle, to help avoid per-
sonal injury or property damage due to
sway caused by crosswinds, rough road
surfaces or passing trucks.
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. when the hitch is
installed.
cTo reduce the possibility of additional
damage if your vehicle is struck from the
rear, remove the hitch when not in use.
After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water or
dust from entering the passenger com-
partment.
cRegularly check that all 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 (located
on the inside of the center console lid).
cTrailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer and tire
manufacturer's specifications.
Safety chain
Always use a suitable chain between your
vehicle and the trailer. The chain should be
crossed and should be attached to the hitch,
not to the vehicle bumper or axle. Be sure toleave enough slack in the chain to permit
turning corners.
Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
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.
CAUTION
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
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
