2004 NISSAN FRONTIER sensor

WARNING
cThe supplemental front air bags ordi-
narily will not inflate in the event of a
side impact, rear impact, rollover, or
lower severity frontal collision. Always
wear your seat belts to help reduce the
risk or severity of injury in various kinds
of accidents.cThe seat belts and the supplemental
front air bags are most effective when
you are sitting well back and upright in
the seat. The front air bags inflate with
great force. If you are unrestrained,
leaning forward, sitting sideways or out
of position in any way, you are at
greater risk of injury or death in a crash.
You may also receive serious or fatal
injuries from the supplemental front air
bag if you are up against it when it
inflates. Always sit back against the
seatback and as far away as practical
from the steering wheel or instrument
panel. Always use the seat belts.cThe driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
air bag system monitors the severity of
a collision and then inflates the air bags
based on belt usage. Failure to properly
wear seat belts can increase the risk or
severity of injury in an accident.
cKeep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the
supplemental front air bag inflates.

The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box.These systems are designed to meet optional
certification requirements under U.S. regulations.
They are also permitted in Canada. The optional
certification allows the front air bags to be de-
signed to inflate somewhat less forcefully than
previously.However, all of the information,
cautions and warnings in this manual still
apply and must be followed.
The supplemental front air bag system is de-
signed to inflate in higher severity frontal colli-
sions, although it may inflate if the forces in an-
other type of collision are similar to those of a
higher severity frontal impact. It may not inflate in
certain frontal collisions. Vehicle damage (or lack
of it) is not always an indication of proper supple-
mental front air bag system operation.
King Cab models are equipped with a supple-
mental front passenger air bag ON/OFF switch.
Because no rear seat exists where a rear facing
child restraint can be secured as in other models,
the switch is designed to turn OFF the passenger
supplemental air bag so that a rear facing child
restraint can be used in the front passenger seat.
See “Passenger supplemental air bag ON/OFF
switch and light” later in this section for details.
Crew Cab models are not equipped with a
supplemental front passenger air bag ON/OFF
switch because they have a rear seat for child
restraint installation. Further, for Crew Cab mod-

els, the supplemental air bag system has dual
stage inflators for both the driver and passenger
air bags. The system monitors information from
the crash zone sensor, the diagnosis sensor unit
and seat belt buckle sensors that detect if the
seat belts are fastened. Inflator operation is
based on the severity of a collision and whether
the seat belts are being used. Only one front air
bag may inflate in a crash, depending on the
crash severity and whether the front occupants
are belted or unbelted. This does not indicate
improper performance of the system. If you have
any questions about the performance of your air
bag system, please contact your NISSAN dealer.
When the supplemental front air bag inflates, a
fairly loud noise may be heard, followed by the
release of smoke. This smoke is not harmful and
does not indicate a fire. Care should be taken to
not inhale it, as it may cause irritation and chok-
ing. Those with a history of a breathing condition
should get fresh air promptly.
Supplemental front air bags, along with the use of
seat belts, help to cushion the impact force on
the face and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air bags
do not provide restraint to the lower body.Seat belts should be correctly worn and the
driver and passenger seated upright as far as
practical away from the steering wheel or instru-
ment panel. The supplemental front air bags in-
flate quickly in order to help protect the front
occupants. Because of this, the force of the front
air bag inflating can increase the risk of injury if
the occupant is too close to, or is against, the
front air bag module during inflation.
The front air bags deflate quickly after a collision.
The supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
WARNING
cDo not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steering
wheel or instrument panel. Such ob-
jects may become dangerous projec-
tiles and cause injury if the supplemen-
tal front air bag inflates.cImmediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
cNo unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the supplemental front air bag system.
cTampering with the supplemental front
air bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the instrument panel or by
installing additional trim material
around the air bag system.

cIf the supplemental air bag warning
light located in the instrument panel
next to the speedometer comes on
when the passenger supplemental air
bag OFF light is also illuminated, some-
thing may be wrong with the air bag
system. Infants, children ages 1-12 or
persons with special medical condi-
tions should not use the front passen-
ger seat until the system is checked by
your NISSAN dealer.
SUPPLEMENTAL AIR BAG
WARNING LABELS
Warning labels about the supplemental front air
bag system are placed in the vehicle as shown in
the illustration.
SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel, moni-
tors the circuits of the supplemental air bag and
pre-tensioner seat belt systems. The circuits
monitored by the supplemental air bag warning
light are the diagnosis sensor unit, crash zone
sensor, supplemental air bag modules, pre-
tensioner seat belts and all related wiring.
When the ignition key is in the ON or START
position, the supplemental air bag warning light
illuminates for about 7 seconds and then turns
off. This means the system is operational.

Zone variation change procedure
The difference between magnetic north and geo-
graphical north is known as variance. In some
areas, this difference can sometimes be great
enough to cause false compass readings. Follow
these instructions to set the variance for your
particular location if this happens:1. Establish your location on the zone map.
Refer to the illustration. Record your zone
number.
2. Turn the ignition switch to the ON position.
3. Push the MODE button in for 5 seconds until
the current zone entry number and the

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.

CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
low tire pressure warning system will not
function properly.

ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary cars. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle.As with
any vehicle, loss of control could result in a
collision with other vehicles or objects, or
cause the vehicle to roll over, particularly if
the loss of control causes the vehicle to
slide sideways.Be attentive at all times, and
avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental air bags” section of this manual,
and also instruct your passengers to do so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person wearing a seat belt.

properly. However, the pulsation may indicate
that road conditions are hazardous and extra care
is required while driving.
Self-test feature
The anti-lock brake system consists of electronic
sensors and hydraulic solenoids controlled by a
computer. The computer has a built-in diagnostic
feature that tests the system each time you start
the engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ‘‘clunk’’ noise and/or feel a pulsa-
tion in the brake pedal. This is normal and is not
an indication of any malfunction. If the computer
senses any malfunction, it switches the anti-lock
brake system off and turns on the ABS brake
warning light on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.
If a malfunction occurs in the system, the anti-
lock function will not operate, but the standard
vehicle brake system will continue to operate
normally. The ABS brake warning light will then
come on.
If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to “Tire plac-
ard” in the “Technical and consumer
information” section of this manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.
