2003 NISSAN SENTRA Owners Manual

cThe seat belts and the supplemental
side air bag are most effective when
you are sitting well back and upright in
the seat. The side air bag inflates with
great force. Do not allow anyone to
place their hand, leg or face near the
side air bag on the side of the seatback
of the front seat. Do not allow anyone
sitting in the front seat to extend their
hand out of the window or lean against
the door.
cWhen sitting in the rear seat, do not
hold onto the seatback of the front seat.
If the side air bag inflates, you may be
seriously injured. Be especially careful
with children, who should always be
properly restrained. Some examples of
dangerous riding positions are shown
in the illustrations.
cDo not use seat covers on the front
seatbacks. They may interfere with
supplemental side air bag inflation.

Supplemental front air bag system
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.

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.
cRight after inflation, several front 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 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 around and on 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 air bag system (if
so equipped)
The supplemental side air bags are located 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 supplemental 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 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 re-
straint 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.

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

cWork around and on the pre-tensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
cIf you need to dispose of the pre-
tensioner or scrap the vehicle, contact a
NISSAN dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate NISSAN Service Manual.
Incorrect disposal procedures could
cause personal injury.
The front seat pre-tensioner seat belt system
activates in conjunction with the supplemental
front air bag. Working with the seat belt retractor,
it helps tighten the seat belt the instant the ve-
hicle becomes involved in certain types of colli-
sions, thereby restraining seat occupants.
The pre-tensioner is encased with the seat belt’s
retractor. These seat belts are used the same as
conventional seat belts.
When the pre-tensioner seat belt activates,
smoke is released and a loud noise may be heard.
This smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it maycause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
If any abnormality occurs in the pre-tensioner
system, the supplemental air bag warning
light
will flash intermittently after the igni-
tion key is turned to the ON or START position. In
this case, the pre-tensioner seat belt will not
function properly. They must be checked and
repaired. Take your vehicle to the nearest
NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pre-tensioner seat belt
system and guide the buyer to the appropriate
sections in this Owner’s Manual.

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, 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 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.
Repair and replacement procedure
The supplemental front air bags, pre-tensioner
seat belts and supplemental side air bags (if soequipped) 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
LOCK position when working under the hood or
inside the vehicle.
WARNING
cOnce a supplemental front air bag or
supplemental side air bag has inflated,
the air bag module will not function
again and must be replaced. Addition-
ally, if any of the supplemental front air
bags inflate, the activated pre-
tensioner seat belts must also be re-
placed. The air bag module and pre-
tensioner seat belt system should be
replaced by a NISSAN dealer. The air
bag module and pre-tensioner seat belt
system cannot be repaired.

PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly ad-
justed and you are sitting upright and well back in
your seat, your chances of being injured or killed
in an accident and/or the severity of injury may be
greatly reduced. NISSAN strongly encourages
you and all of your passengers to buckle up every
time you drive, even if your seating position in-
cludes a supplemental air bag.
Most U.S. states and Canadian provinces
or territories specify that seat belts be worn
at all times when a vehicle is being driven.
