2004 NISSAN FRONTIER fuel

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.

To resume the preset speed,push and re-
lease the RES/ACCEL switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
cAvoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
cDo not accelerate at full throttle in any gear.
cAvoid quick starts.
cAvoid hard braking as much as possible.
cDo not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged.cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
cKeep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.

PROCEDURES
WARNING
cWhen parking always make sure the
transfer control lever is in the 2H, 4H or
4L position and the parking brake is
applied.cDo not leave the transfer control lever in
the N (Neutral) position. Otherwise, the
vehicle could roll unexpectedly even if
the manual transmission is in any gear
or the automatic transmission is in the
P (Park) position. This could result in
serious personal injury or property
damage.
cFailure to engage the transfer control
lever in 2H, 4H or 4L could result in the
vehicle moving unexpectedly, which
could cause serious personal injury or
property damage.
CAUTION
Do not drive on dry hard surface roads in
four-wheel drive. Driving on dry hard sur-
faces in 4H or 4L may cause unnecessary
noise, tire wear, and increased fuel con-
sumption. NISSAN recommends driving in
the 2H position under these conditions.
2H— (2WD, high range) Only the rear wheels
are driven. Use for driving under the same condi-
tions as standard 2WD vehicles or state dyna-
mometer I/M testing.
4H— (4WD, high range) Four wheels are driven.
Use when driving on roads where it is difficult to

drive in the 2H position (for example, driving at
normal speeds on snow covered, icy, wet, muddy
or sandy roads) .
The 4H position provides greater power and
traction. Avoid excessive speed as it will cause
increased fuel consumption, higher oil tempera-
ture and could damage drivetrain components.
Speed over 50 MPH (80 km/h) in 4H are not
recommended.
4L— (4WD, low range) Four wheels are driven.
Use when climbing or descending steep hills, or
during driving in sand, mud or deep snow. The 4L
position provides maximum power and traction.
Avoid raising vehicle speed excessively, as the
recommended maximum speed is approximately
30 MPH (48 km/h) .
N— No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position. Shift
the lever quickly and smoothly when moving
across the N (Neutral) position with the vehicle
stopped.
AUTO-LOCK FREE-
RUNNING HUBS
The auto-lock free-running hub is designed to
allow for automatic four-wheel drive engagement
when the shift lever is moved to the 4H or 4L
position. Follow these operational cautions:
CAUTION
cThe auto-locking hubs will make a
clicking noise when engaging and dis-
engaging. This is normal.cAccelerating quickly from a stop after
shifting from two-wheel drive to four-
wheel drive may not allow engagement
of the auto-locking free-running hubs
and may cause a clattering noise. If this
occurs, release the accelerator pedal to
reduce the engine speed or stop the
vehicle. Continued use of the vehicle
with this noise may damage the hub
lock.
cIf the auto-locking hubs make a clatter-
ing noise after shifting from four-wheel
drive to two-wheel drive, stop and move
the vehicle in reverse gear, in a straight
line, about 7 to 10 feet (2 to 3 m) .
cUnder extremely cold conditions [below
5°F (-15°C)], the front axle shafts may
rotate even with the transfer lever in the
2H position. If this occurs, the auto-
locking hubs may make a clattering
noise. To avoid this, drive first in four-
wheel drive to warm up the vehicle and
differential gear oil. Then, shift to two-
wheel drive.
cIn cold weather, it may be necessary to
reduce speed or stop the vehicle in or-
der to shift from two-wheel drive to
four-wheel drive.
