WARNING
cNever let children ride unrestrained.
Do not attempt to hold them in your
lap or arms. Some examples of dan-
gerous riding positions are shown in
the previous illustrations.
cChildren may be severely injured or
killed when the supplemental air bag
inflates if they are not properly re-
strained.
cNever install a rear-facing child re-
straint in the front seat. An inflating
supplemental air bag could seri-
ously injure or kill your child. See

The driver supplemental air bag is located in
the center of the steering wheel. The front
passenger supplemental 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 air
bags to be designed to inflate somewhat
less forcefully than previously.However, all
of the information, cautions and warn-
ings in this manual still apply and must
be followed.
The supplemental air bag system is de-signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another 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 air bag
system operation.
When the supplemental 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, but
care should be taken not to unintentionally
inhale it, as it may cause irritation andchoking. Those with a history of breathing
trouble should get fresh air promptly.
The supplemental 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 seri-
ous injuries. However, an inflating supple-
mental air bag may cause facial abrasions
or other injuries. Supplemental 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. Since the supplemental air
bags inflate quickly in order to help protect
the front occupants, the force of the supple-
mental air bag inflating can increase the risk
of injury if the occupant is too close to or is
against the supplemental air bag module
during inflation.
The supplemental air bags deflate quickly
after a collision.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.

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 air bag inflates.
cRight after inflation, several supple-
mental air bag system components
will be hot. Do not touch them; you
may severely burn yourself.
c
No 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,
suspension system or front end
structure. This could affect proper
operation of the supplemental air
bag system.c
Tampering with the supplemental air
bag system may result in serious per-
sonal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the dashboard, or by install-
ing additional trim material around the
supplemental air bag system.
cWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN dealer. The yellow SRS wiring
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the supple-
mental air bag system.
cThe SRS wiring harnesses are cov-
ered with yellow insulation either
just before the harness connectors
or over the complete harness for
easy identification.When selling your vehicle, we request that
you inform the buyer about the supple-
mental air bag system and guide the buyer
to the appropriate sections in this owner's
manual.

Warning labels about the supplemental air
bag system are placed in the vehicle as
shown in the illustration.The supplemental air bag warning light,
displayingin the instrument panel,
monitors the circuits of the supplemental air
bag system. The circuits monitored by the
supplemental air bag warning light are the
diagnosis sensor unit, supplemental air bag
modules 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.

If any of the following conditions occur, the
supplemental air bag needs servicing:
1. The supplemental air bag warning light
does not come on and remain on for 7
seconds and then go off as described.
2. The supplemental air bag warning light
flashes intermittently or remains on.
3. The supplemental air bag warning light
does not come on at all.
Under these conditions, the supplemental
restraint system air bag may not operate
properly. It must be checked and repaired.
Take your vehicle to the nearest authorized
NISSAN dealer.
WARNING
If the supplemental air bag warning
light is on, it could mean that the
supplemental air bag system will not
operate in an accident.
Repair and replacement procedure
The supplemental air bag modules are de-
signed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag light remains illumi-nated after inflation has occurred. Repair
and replacement of the supplemental air
bag system should be done only by an
authorized NISSAN dealer.
To ensure long-term functioning, the
supplemental air bag system must be
inspected 10 years after the date of
manufacture as noted on the certifica-
tion label located on the driver side front
pillar.
When maintenance work is required on the
vehicle, the supplemental air bag system
and related parts should be pointed out to
the person conducting the maintenance.
The ignition key should always be in the
LOCK position when working under the
hood or inside the vehicle.
WARNING
cOnce the supplemental air bag in-
flates, the supplemental air bag
module will not function again and
should be replaced by an authorized
NISSAN dealer. The supplemental air
bag module cannot be repaired.cThe supplemental air bag system
should be inspected by an autho-
rized NISSAN dealer if there is any
damage to the front end portion of
the vehicle.
cIf you need to dispose of a supple-
mental air bag or scrap the vehicle,
contact an authorized NISSAN
dealer. Correct supplemental air bag
disposal procedures are set forth in
the appropriate NISSAN Service
Manual. Incorrect disposal proce-
dures could cause personal injury.

PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly
adjusted, 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 includes
a supplemental air bag.
Most U.S. states and all Canadian prov-
inces and territories, require that seat belts
be worn at all times when a vehicle is being
driven.
WARNING
cEvery person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be prop-
erly restrained and, if appropriate, in
a child restraint.
c
The belt should be properly adjusted
to a snug fit. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an acci-
dent. Serious injury or death can occur
if the seat belt is not worn properly.cAlways route the shoulder belt over
your shoulder and across your chest.
Never run the belt behind your back,
under your arm or across your neck.
The belt should be away from your
face and neck, but not falling off your
shoulder.cPosition the lap belt as low and snug
as possible AROUND THE HIPS,
NOT THE WAIST. A lap belt worn too
high could increase the risk of inter-
nal injuries in an accident.

cBe sure the seat belt tongue is se-
curely fastened to the proper buckle.
cDo not wear the belt inside out or
twisted. Doing so may reduce its
effectiveness.
cDo not allow more than one person
to use the same belt.
cNever carry more people in the ve-
hicle than there are seat belts.cIf the seat belt warning light glows
continuously while the ignition is
turned ON with all doors closed and
all seat belts fastened, it may indi-
cate a malfunction in the system.
Have the system checked by an au-
thorized NISSAN dealer.c
All seat belt assemblies including
retractors and attaching hardware
should be inspected after any colli-
sion by an authorized NISSAN
dealer. NISSAN recommends that all
seat belt assemblies in use during a
collision be replaced unless the col-
lision was minor and the belts show
no damage and continue to operate
properly. Seat belt assemblies not in
use during a collision should also be
inspected and replaced if either dam-
age or improper operation is noted.
