2004 NISSAN FRONTIER inflation pressure

inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability. Each
tire, including the spare, should be checked
monthly when cold and set to the recommended
inflation pressure as specified in the vehicle plac-
ard and owner’s manual.
Low pressure warning
If the vehicle is being driven with very low tire
pressure (lower than 28 psi, 193 kPa) , the light
will illuminate and the chime will sound for about
10 seconds.
For additional information, see “Low tire pressure
warning system” in the “Starting and driving”
section and “Low tire pressure warning system”
in the “In case of emergency” section.
WARNING
cIf the light does not come on with the
key switch turned ON, have the vehicle
checked by a NISSAN dealer as soon as
possible.cIf the light comes on while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the tire
placard to turn the low tire pressure
warning light OFF. If the light still
comes on while driving after adjusting
the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a
spare tire as soon as possible.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
CAUTION
cThe low tire pressure warning system is
not a substitute for the regular tire pres-
sure check. Be sure to check the tire
pressure regularly.
cIf the vehicle is being driven at speeds
of less than 20 MPH (32 km/h) , the low
tire pressure warning system may not
operate correctly.
cBe sure to install the specified size of
tires to the 4 wheels correctly.

cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.
LOW TIRE PRESSURE WARNING
SYSTEM
The low tire pressure warning system monitors
tire pressure of all tires (except the spare tire) .
The low tire pressure warning system will activate
only when the vehicle is driven at speeds above
20 MPH (32 km/h) . Also, this system may not
detect a sudden drop in tire pressure (for ex-
ample a flat tire while driving) .Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the tire
which can cause a lower tire inflation pressure.
This may cause the low tire pressure warning
light to illuminate.
If the warning light illuminates in low ambient
temperature as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown
on the tire placard to turn the low tire pressure
warning light OFF.
Frequently check the tire pressure and adjust
pressure of each tire properly.
Low tire pressure warning
If the vehicle is being driven with very low tire
pressure (lower than 28 psi, 193 kPa) , the low
tire pressure warning light comes on and the
chime sounds for about 10 seconds.
For additional information regarding the above
warning, see “Warning/indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section.
WARNING
cIf the low tire pressure warning light
flashes while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Serious vehicle
damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pressure
for all four tires. Adjust the tire pressure
to the recommended COLD tire pres-
sure shown on the tire placard to turn
the low tire pressure warning light OFF.
If you have a flat tire, replace it with a
spare tire as soon as possible. (See
“Flat tire” in the “In case of emergency”
section for changing a flat tire.)
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.

TIRE PRESSURE
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips. The
recommended tire pressure specifications are
shown on the Tire and Loading Information label
(this label is also known as the tire placard) under
the9Recommended Cold Tire Inflation Pressure9
heading. The Tire and Loading Information label
is affixed to the driver side center pillar. Tire
pressures should be checked regularly because:
cMost tires naturally lose air over time.
cTires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curb while parking.
The tire pressures should be checked when the
tires are cold. The tires are considered COLD
after the vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km) at
moderate speeds.
Incorrect tire pressure, including under in-
flation, may adversely affect tire life and
vehicle handling.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident.
cThe vehicle weight capacity is indicated
on the Tire and Loading Information
label. Do not load your vehicle beyond
this capacity. Overloading your vehicle
may result in reduced tire life, unsafe
operating conditions due to premature
tire failure, or unfavorable handling
characteristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
cBefore taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
c
Do not drive your vehicle over 85 MPH
(137 km/h) unless it is equipped with high
speed rated tires. Driving faster than 85
MPH (137 km/h) may result in tire failure,
loss of control and possible injury.
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.

Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
Otherwise, your vehicle could be damaged or
involved in an accident:
WARNING
cThe spare tire should be used for emer-
gency use only. It should be replaced
with the standard tire at the first oppor-
tunity to avoid possible tire or differen-
tial damage.
cDrive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
cPeriodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 60 psi (420 kPa, 4.2 bar) .
cWith the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 50 MPH (80 km/h) .cWhen driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
front wheels and the original tire used
on the rear wheels (drive wheels) . Use
tire chains only on the two rear original
tires.
cTire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate
than the standard tire. Replace the
spare tire as soon as the tread wear
indicators appear.
cDo not use the spare tire on other
vehicles.
cDo not use more than one spare tire at
the same time.
cDo not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
cWith the spare tire installed the
transfer control lever must be in the 2H
position to prevent the transfer case
and differential gears from being
damaged.cDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause dam-
age to the vehicle.
cBecause the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.

WARNING
Improper loading may be dangerous. If a
load is too far back, it can affect handling
characteristics. If a load is too far forward,
the front axle may be overloaded.
When the truck is used to carry a slide-in camper,
the total cargo load of the truck consists of the
camper manufacturer’s weight figure, plus:
cthe weight of installed additional camper
equipment not included in the camper
manufacturer’s weight figure,
cthe weight of camper cargo,
cand the weight of occupants in the camper.
The total cargo load should not exceed the
truck’s pay load weight rating and the camper’s
center of gravity should fall within the truck’s
recommended center of gravity location zone
when installed.
WARNING
Overloading or improper loading can ad-
versely affect vehicle handling, braking
and performance and may lead to
accidents.
VEHICLE LOAD WEIGHT CAPACITY
The vehicle load weight capacity shown on fol-
lowing charts indicate the maximum total weight
of passengers, optional equipment (air condition-
ing, trailer hitch, etc) and cargo that your vehicle
is designed to carry.
Before driving a loaded vehicle, confirm that you
do not exceed the Gross Vehicle Weight Rating
(GVWR) or the Gross Axle Weight Rating
(GAWR) for your vehicle. See ’’Vehicle Loading
Information’’ earlier in this section for details.
Also check tires for proper inflation pressures.
See the tire placard.
