To check the fluid level, use your finger to plug
the center hole of the cap/tube assembly (as
shown above), then remove it from the tank. If
there is no fluid in the tube, add fluid. Add awasher solvent to the water for better cleaning.
In the winter season, add a windshield washer
anti-freeze. Follow the manufacturer's instruc-
tions for the mixture ratio.
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.
IKeep the battery surface clean and dry. Any
corrosion should be washed off with a
solution of baking soda and water.
IMake certain the terminal connections are
clean and securely tightened.
IIf the vehicle is not to be used for 30 days or
longer, disconnect the ªÐº negative battery
terminal cable to prevent discharge.
Do not expose the battery to flames or

Summer tires
NISSAN specifies summer tires on some mod-
els 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 ªM&Sº on
the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, NISSAN recommends the use
of ªSNOWº or ªALL SEASONº 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 handling 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 provinces
and states 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 bepoorer than that of non-studded snow tires.
Tire chains
Use of tire chains may be prohibited according
to location. Check the local laws before install-
ing 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 suggestions. 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 possibility
of whipping action damage to the fenders or
undercarriage. In addition, drive at a reduced
speed. Otherwise, your vehicle may be dam-
aged and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a T-type spare tire.
Do not use the chains on dry roads.
Tire rotation
NISSAN recommends that tires be rotated
every 7,500 miles (12,000 km).
Wheel nut tightening torque:
72 to 87 ft-lb (98 to 118 )
See ªFlat tireº in the ªIn case of emergencyº
section for tire replacing procedures.

During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer do it promptly. In addition,
you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, closely observe the precautions in the
ªDo-it-yourself operationsº section.
Additional information on the following
items with ª*º is found in the ªDo-it-
yourself operationsº section.
OUTSIDE THE VEHICLE
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.

odically when at a service station, including the
spare, and adjust to the specified pressure if
necessary. Check carefully for damage, cuts
or excessive wear.
Wheel nuts*When checking the tires, make
sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every7,500 miles (12,000 km).
Wheel alignment and balanceIf the vehicle
pulls 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 and engine hoodCheck that all doors
and the engine hood operate smoothly as well
as the trunk lid or back hatch. Also make sure
that all latches lock securely. Lubricate if nec-
essary. Make sure that the secondary latch
keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
INSIDE THE VEHICLE
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.

held securely on a fairly steep hill when only
the parking brake is applied.
Automatic transaxle ªParkº mechanismCheck that the brake pedal must be depressed
for the selector lever to be moved from the ªPº
position. On a fairly steep hill check that the
vehicle is held securely with the selector lever
in the ªPº 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).
Windshield washer fluid*Check that there is
adequate fluid in the tank.
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, deformation, dete-
rioration or loose connections.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid levels are between
the ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
Engine drive belts*Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*Check the level on thedipstick after parking the vehicle on a level
spot and turning off the engine. Be sure to wait
a few minutes to allow the oil to drain back into
the sump.
Power steering fluid level* and linesCheck
the level in the reservoir tank with the engine
off. Check the lines for proper attachment,
leaks, cracks, etc.
Automatic transaxle fluid level*Check the
level on the dipstick after putting the selector
lever in ªPº with the engine idling.
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 locate the
trouble and correct it. (See the carbon monox-
ide warning in the ªStarting and drivingº sec-
tion)
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. See the ªAppearance and interior
careº section for additional information.

rear GAWR is exceeded, shift the load or
remove cargo as necessary.
Loading tips
IThe GVW must not exceed GVWR or
GAWR as specified on the FMVSS Certifi-
cation Label.
IDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
IProperly secure all cargo to help pre-
vent it from sliding or shifting. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
IDo 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.
IOverloading can shorten the life of
your vehicle. Failures caused by
overloading are not covered by yourwarranty.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
Information on trailer towing ability and the
special equipment required should be ob-
tained from your Nissan dealer. He can obtain
aNissan Trailer Towing Guidefor you.

Maximum load limits
Maximum trailer loads
Never allow the total trailer load to exceed
1,000 lb (454 kg). The total trailer load equals
trailer weight plus its cargo weight. Towing
loads greater than 1,000 lb (454 kg) or using
improper towing equipment could adversely
affect vehicle handling, braking and perfor-
mance.
Vehicle damage and/or personal injury
resulting from improper towing proce-
dures is not covered by NISSAN warran-
ties. Information on trailer towing and
required towing equipment should be
obtained from dealers who specialize in
providing trailers or other towing
equipment.
Tongue load
Keep the tongue load between 9 and 11% of
the total trailer load. If the tongue load be-
comes excessive, rearrange cargo to allow for
proper tongue load.Maximum gross vehicle weight/maximum
gross axle weight
The gross vehicle weight of the towing vehicle
must not exceed the gross vehicle weight
rating (GVWR) shown on the F.M.
V.S.S. certification label. The gross vehicle
weight equals the combined weight of the
unloaded vehicle, passengers, luggage, hitch,
trailer tongue load and any other optional
equipment. In addition, front or rear gross axle
weight must not exceed the gross axle weight
rating (GAWR) shown on the F.M.V.S.S. cer-
tification label.

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 personal
injury or property damage due to sway caused
by crosswinds, rough road surfaces or passing
trucks.
IAxle-mounted hitches should not be used.
IThe hitch should not be attached to or affect
the operation of the impact-absorbing
bumper
IDo not modify the vehicle exhaust system,
brake system, etc. when the hitch is in-
stalled.
ITo reduce the possibility of additional dam-
age 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 compartment.
TI1012M

Z01.2.1/A32-DX

IRegularly check that all hitch mounting
bolts are securely mounted.
Tire pressures
IWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pressure
indicated on the tire placard (located on the
inside of the center console lid.)
ITrailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer and tire manufac-
turers' 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 to
leave enough slack in the chain to permit
turning corners.
Trailer lights
Trailer lights should comply with Federal
and/or local regulations. When wiring the ve-
hicle for towing, connect the stop and tail light
pickup into the vehicle electrical circuit at a
point between the sensor and stop light or light
switch.
Trailer brakes
If your trailer is equipped with a braking sys-
tem, make sure it conforms to Federal and/or
local regulations and that it is properly in-
stalled.
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
IBe 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 or other pos-
sible causes of either condition.
IAlways secure items in the trailer to prevent
load shifts while driving.
IBe certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so, and if your vehicle is equipped
with automatic transmission, first block the
wheels and apply the parking brake, and
then move the transmission shift lever into
the ªPº position. If you move the shift lever
to the ªPº position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
