2004 NISSAN SENTRA wiring

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.
cWork on and around the supplemental
front air bag system should be done by
a NISSAN dealer. Installation of electri-
cal equipment should also be done by a
NISSAN dealer. The Supplemental Re-
straint System (SRS) wiring should not
be modified or disconnected. Unautho-
rized electrical test equipment and
probing devices should not be used on
the air bag system.
cA cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield could
affect inflation of the supplemental air
bag system.

bag system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.
Supplemental side-impact air bag sys-
tem (if so equipped)
The supplemental side-impact air bags are lo-
cated in the outside of the seatback of the front
seats. The supplemental side air bag (on the
driver or front passenger seat) is designed to
inflate in higher severity side collisions, although
it may inflate if the forces in another type of
collision are similar to those of a higher severity
side impact. It is designed to inflate on the side
where the vehicle is impacted. It may not inflate in
certain side collisions. Vehicle damage (or lack of
it) is not always an indication of proper supple-
mental side air bag operation.When the supplemental side air bag inflates, a
fairly loud noise may be heard, followed by re-
lease 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 side air bags, along with the use of
seat belts, help to cushion the impact force on
the head and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating side air bag may cause
abrasions or other injuries. Side air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn and the
driver and passenger seated upright as far as
practical away from the supplemental side air
bag. The side air bag inflates quickly in order to
help protect the front occupants. Because of this,
the force of the side air bag inflating can increase
the risk of injury if the occupant is too close to, or
is against, the side air bag module during infla-
tion. The side air bag will deflate quickly after a
collision.
The supplemental side 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 near the seat-
back of the front seats. Also, do not
place any objects (an umbrella, bag,
etc.) between the front door finisher
and the front seat. Such objects may
become dangerous projectiles and
cause injury if the supplemental side air
bag inflates.
cRight after inflation, several supple-
mental side air bag system components
will be hot. Do not touch them; you may
severely burn yourself.
cNo unauthorized changes should be
made to any components or wiring of
the supplemental side air bag system.
This is to prevent accidental inflation of
the side air bag or damage to the side
air bag system.cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the
side air bag system.
cTampering with the supplemental side
air bag system may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial near the seatback or by installing
additional trim material, such as seat
covers, around the side air bag.
cWork around and on the supplemental
side air bag system should be done by a
NISSAN dealer. Installation of electrical
equipment should also be done by a
NISSAN dealer. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag system.
* The SRS wiring harness connectors are
yellow for easy identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental side air
bag system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.
Pre-tensioner seat belt system (for
front seats)
WARNING
cThe pre-tensioner seat belt cannot be
reused after activation. It must be re-
placed together with the retractor and
buckle as a unit.
cIf the vehicle becomes involved in a
frontal collision but the pre-tensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
cNo unauthorized changes should be
made to any components or wiring of
the pre-tensioner seat belt system. This
is to prevent accidental activation of
the pre-tensioner seat belt or damage
to the pre-tensioner seat belt operation.
Tampering with the pre-tensioner seat
belt system may result in serious per-
sonal injury.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel, moni-
tors the circuits of the supplemental front air
bags, pre-tensioner seat belt and supplemental
side air bag (if so equipped) systems. The circuits
monitored by the supplemental air bag warning
light are the diagnosis sensor unit, 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 lightilluminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag and pre-tensioner seat belt systems need
servicing:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light does
not come on at all.
Under these conditions, the supplemental front
air bag, supplemental side air bag or pre-
tensioner seat belt systems may not operate
properly. It must be checked and repaired. Take
your vehicle to the nearest NISSAN dealer.
WARNING
If the supplemental air bag warning light
is on, it could mean that the supplemental
front air bag or supplemental side air bag
system will not operate in an accident. To
help avoid injury to yourself or others,
have your vehicle checked by a NISSAN
dealer as soon as possible.
Repair and replacement procedure
The supplemental front air bags, pre-tensioner
seat belts and supplemental side air bags (if so
equipped) are designed to inflate on a one-time-
only basis. As a reminder, unless it is damaged,
the supplemental air bag warning light remains
illuminated after inflation has occurred. Repair
and replacement of these supplemental air bag
systems should be done only by a NISSAN
dealer.
When maintenance work is required on the ve-
hicle, the supplemental front air bags, supple-
mental side air bags (if so equipped) , pre-
tensioner seat belts and related parts should be
pointed out to the person performing the mainte-
nance. The ignition key should always be in the

WARNING
cOn hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or possi-
bly fatal injuries to people or animals.
Do not leave children or adults who
would normally require the support of
others in your vehicle. Unattended pets
should not be left alone either.
cClosely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.cIf you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
cDo not run the engine in closed spaces
such as a garage.
cDo not park the vehicle with the engine
running for any extended length of time.
cKeep the trunk lid closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the trunk lid
open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the fan
control dial to 4 (high) to circulate
the air.
cIf electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
cThe exhaust system and body should be
inspected by a qualified mechanic
whenever:a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
