2003 NISSAN FRONTIER belt

FLOOR MATS
The use of genuine NISSAN floor mats can ex-
tend the life of your vehicle carpet and make it
easier to clean the interior.No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation.Mats should be maintained
with regular cleaning and replaced if they be-
come excessively worn.
Floor mat positioning aid (driver’s side
only)
This vehicle includes a front floor mat bracket to
act as a floor mat positioning aid. NISSAN floor
mats have been specially designed for your ve-
hicle model. The driver’s side floor mat has a
grommet hole incorporated in it. Position the mat
by placing the floor mat bracket hook through the
floor mat grommet hole while centering the mat in
the footwell.
Periodically check to make certain the mats are
properly positioned.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. See “Seat belt maintenance”
in the “Seats, restraints and supplemental air bag
systems” section of this manual.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely
weaken the seat belt webbing.

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 vehicle
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.
cFor additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet .
WindshieldClean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
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. Lubricatehinges, latches, latch pins, rollers and links as
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*Clean the headlights on a regular basis.
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.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.

Brake pedal and booster*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 the
floor mat away from the pedal.
Parking brake*Check that the pedal 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) position
mechanismCheck that the lock release button
on the shift 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 (for example, each time you
check the engine oil or refuel) .
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 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 between the
MIN and MAX lines on the reservoir.
Power steering fluid level* and linesCheck
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, deformation, 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. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell ofexhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
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 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 thor-
oughly 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 imme-
diately.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For automatic transmission mod-
els, move the selector lever to P (Park) .
cBe sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
cNever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage.If in doubt about any servicing,
have it done by a NISSAN dealer.

ous and should be stored carefully in
marked containers out of the reach of
children.
TEMPERATURE CONDITIONS FOR
CHECKING
cThe fluid level should be checked using the
HOT range on the dipstick after the following
conditions have been met:
– The engine should be warmed up to op-
erating temperature.
– The vehicle should be driven at least 5
minutes.
– The automatic transmission fluid should
be warmed to 122 - 176°F (50 - 80°C) .cThe fluid can be checked at fluid temperatures
of 86 - 122°F (30 - 50°C) using the COLD
range on the dipstick after the engine is

cThe original tires have built-in tread
wear indicators. When the wear indica-
tors are visible, the tire(s) should be
replaced.
cImproper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, con-
tact a NISSAN dealer.
cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels/tire size” in the
“Technical and consumer information” section of
this manual.
WARNING
cThe use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
cIf the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheel/tire size” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.cWhen a spare tire is mounted or a wheel
is replaced, the low tire pressure warn-
ing system will not function. Contact
your NISSAN dealer as soon as pos-
sible for tire replacement and/or sys-
tem resetting (for models with the low
tire pressure warning system) .
cDo not install a deformed wheel or tire
even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warning.
cThe use of retread tires is not
recommended.
cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.
