2002 NISSAN SENTRA dashboard

Supplemental front air bag system
The driver supplemental front air bag is lo-
cated 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 op-
tional certification requirements under U.S.
regulations. They are also permitted in
Canada. The optional certification allows
the front air bags to be designed to inflate
somewhat less forcefully than previously.
However, all of the information, cautions
and warnings in this manual still applyand must be followed.
The front air bag system is designed to
inflate in higher severity frontal collisions,
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 supplemental front air
bag system operation.
When the supplemental front air bag in-
flates, 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 choking.
Those with a history of a breathing condition
should get fresh air promptly.
The supplemental front air bags, along with
the use of seat belts, help to cushion the
impact force on the face and chest of the
occupant. They can help save lives and
reduce serious injuries. However, an inflat-
ing 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
instrument panel. The supplemental front air
bags inflate quickly in order to help protect
the front occupants. Because of this, the
force of the front air bag inflating can in-
crease 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 warn-
ing light illuminates. The supplemental
air bag warning light will turn off after
about 7 seconds if the system is opera-
tional.
WARNING
c
Do 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 steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the supple-
mental front air bag inflates.
cRight after inflation, several front air
bag system components will be hot.
Do not touch them; you may se-
verely burn yourself.
c
No unauthorized changes should be
made to any components or wiring of
the supplemental front air bag sys-
tem. This is to prevent accidental in-
flation of the front air bags or damage
to the front air bag system.cDo not make unauthorized changes to
your vehicle's electrical system, sus-
pension system or front end struc-
ture. This could affect proper opera-
tion of the supplemental front air bag
system.
cTampering with the supplemental
front air bag system may result in
serious personal injury. For ex-
ample, do not change the steering
wheel and instrument panel assem-
bly by placing material over the
steering wheel pad and above the
dashboard or by installing additional
trim material around the front air bag
system.
cWork around and on the supplemen-
tal front air bag system should be
done by an authorized NISSAN
dealer. Installation of electrical
equipment should also be done by
an authorized NISSAN dealer. The
SRS wiring should not be modified
or disconnected. Unauthorized elec-
trical test equipment and probing
devices should not be used on the
supplemental front air bag system.

locking up, the actuator (under the hood)
rapidly applies and releases hydraulic pres-
sure (like pumping the brakes very quickly).
While the actuator is working, you may feel
a pulsation in the brake pedal and hear a
noise or vibration from the actuator under
the hood. This is normal and indicates that
the anti-lock system is working 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 is a sophisti-
cated device with electronic sensors, elec-
tric pumps, and hydraulic solenoids con-
trolled by a computer. The computer has a
built-in diagnostic feature that tests the sys-
tem 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
pulsation 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 in
the dashboard. The brake system then op-erates normally, but without anti-lock assis-
tance.
If the light comes on during the self-test or
while driving, take the vehicle to an autho-
rized NISSAN dealer for repair.
WARNING
c
The anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces, but remember that the stop-
ping distance on slippery surfaces
will be longer than on normal sur-
faces, even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow
covered roads, or if you are using tire
chains. Always maintain a safe dis-
tance from the vehicle in front of you.
Ultimately, the responsibility for
safety of self and others rests in the
hands of the driver.
Tire type and condition of tires may
also affect braking effectiveness.cWhen replacing tires, install the
specified tire size on all four wheels.
c
When installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the ``Technical and
consumer information'' section of
this manual.
cFor additional information, refer to
``Wheels and tires'' in the ``Mainte-
nance and do-it-yourself'' section of
this manual.
