Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact
force to the head of occupants in front and
rear outboard seating positions in certain
side-impact or rollover collisions. In a side-
impact, the curtain air bags are designed
to inflate on the side where the vehicle is
impacted. In a rollover, the curtain air bags
are designed to inflate and remain inflated
for a short time.
The SRS is designed tosupplementthe
crash protection provided by the seat belts
and is not a substitute for them. Seat belts
should always be correctly worn and the
occupant seated a suitable distance away
from the steering wheel, instrument panel
and door finishers. For additional informa-
tion, refer to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
•
The front air bags ordinarily will not in-
flate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat
belts to help reduce the risk or severity
of injury in various kinds of accidents.
•The front passenger air bag will not
inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.
• The seat belts and the front air bags
are most effective when you are sit-
ting well back and upright in the seat.
The front air bags inflate with great
force. Even with the NISSAN Ad-
vanced Air Bag System, if you are un-
restrained, 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 re-
ceive serious or fatal injuries from
the 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

This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada.However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.
The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensors, occupant classifica-
tion sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator opera-
tion is based on the severity of a collision
and seat belt usage for the driver. For the front passenger, it additionally monitors
the weight of an occupant or object on the
seat and seat belt tension. Based on infor-
mation from the sensors, only one front air
bag may inflate in a crash, depending on
the crash severity and whether the front
occupants are belted or unbelted. Addi-
tionally, the front passenger air bag may be
automatically turned off under some con-
ditions, depending on the weight detected
on the front passenger seat and how the
seat belt is used. If the front passenger air
bag is OFF, the front passenger air bag sta-
tus light will be illuminated (if the seat is
unoccupied, the light will not be illumi-
nated, but the air bag will be off ). For addi-
tional information, refer to “Front passen-
ger air bag and status light” in this section.
One front air bag inflating does not indicate
improper performance of the system.
If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact NISSAN. Con-
tact information is contained in the front of
this Owner's Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by the 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 irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.
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 seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front passenger seated upright
as far as practical away from the steering
wheel or instrument panel. The 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 af ter a
collision.
1-78Safety-Seats, seat belts and supplemental restraint system

The front air bags operate only when the
ignition switch is in the ON or START po-
sition.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
Front passenger air bag and status light
WARNING
The front passenger air bag is designed
to automatically turn OFF under some
conditions. Read this section carefully
to learn how it operates. Proper use of
the seat, seat belt and child restraints is
necessary for most effective protec-
tion. Failure to follow all instructions in
this manual concerning the use of
seats, seat belts and child restraints
can increase the risk or severity of in-
jury in an accident. Status light
The front passenger air bag status light
is located near the climate controls.
Af ter the ignition switch is placed in the
"ON" position, the front passenger air bag
status light on the instrument panel illumi-
nates for about 7 seconds and then turns
off or remains illuminated depending on
the front passenger seat occupied status.
The light operates as follows:
• Unoccupied front passenger's seat: The
light is OFF and the front passenger
air bag is OFF and will not inflate in a
crash.
• Front passenger's seat occupied by a small adult, child or child restraint as out-
lined in this section: The
light illumi-
nates to indicate that the front passen-
ger air bag is OFF and will not inflate in a
crash.
• Occupied front passenger seat and the passenger meet the conditions outlined
in this section: The
light is OFF to
indicate that the front passenger air bag
is operational.

seat, contrary to the instructions in this
manual. Always be sure that you and all
vehicle occupants are seated and re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag is automatically turned OFF
with the seat occupied. The light will not
illuminate when the front passenger seat is
unoccupied.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the air bag is OFF),
it could be that the person is a small adult,
or is not sitting on the seat properly or not
using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending
on the size of the child and the type of child
restraint being used. If the air bag status light
is not illuminated (indicating that the air bag
might inflate in a crash), it could be that the
child restraint or seat belt is not being used
properly. Make sure that the child restraint is
installed properly, the seat belt is used prop-
erly and the occupant is positioned properly.
If the air bag status light is not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the front passenger air bag status light
will not illuminate even though you believe
that the child restraint, the seat belts and
the occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). A
NISSAN dealer can check that the system is
OFF by using a special tool. However, until
you have confirmed with a dealer that your
air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the passenger seat status. For example, if a
large adult who is sitting in the front pas-
senger seat exits the vehicle, the front pas-
senger air bag status light will go from OFF
to ON for a few seconds and then to OFF.
This is normal system operation and does
not indicate a malfunction.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will blink. Have the system checked. It
is recommended that you visit a NISSAN
dealer for this service. Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
• 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 dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.

inflate if the forces in another type of colli-
sion are similar to those of a higher severity
impact. They are designed to inflate on the
side where the vehicle is impacted. They
may not inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near roll-
overs. As a result, certain vehicle movements
(for example, during severe off-roading) may
cause the curtain air bags to inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by release of smoke. This smoke is
not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it
may cause irritation and choking. Those
with a history of a breathing condition
should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvic area of the front occu-
pants. Curtain air bags help to cushion the
impact force to the head of occupants in
the front and rear outboard seating posi-
tions. They can help save lives and reduce
serious injuries. However, an inflating sideair bag or curtain air bag may cause abra-
sions or other injuries. Side air bags and
curtain air bags do not provide restraint to
the lower body.
The seat belts should be correctly worn
and the driver and passenger seated up-
right as far as practical away from the side
air bag. Rear seat passengers should be
seated as far away as practical from the
door finishers and side roof rails. The side
air bags and curtain air bags inflate quickly
in order to help protect the occupants. Be-
cause of this, the force of the side air bag
and curtain air bag inflating can increase
the risk of injury if the occupant is too close
to, or is against, these air bag modules dur-
ing inflation. The side air bag will deflate
quickly af ter the collision is over.
The curtain air bags will remain inflated for
a short time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON or START position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
• Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door fin-
isher and the front seat. Such objects
may become dangerous projectiles
and cause injury if a side air bag
inflates.
• Right af ter inflation, several side air
bag and curtain air bag system com-
ponents will be hot. Do not touch
them; you may severely burn
yourself.
• No unauthorized changes should be
made to any components or wiring
of the side air bag and curtain air bag
systems. This is to prevent damage
to or accidental inflation of the side
air bag and curtain air bag systems.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or side panel.
This could affect proper operation of
the curtain air bag systems.
Safety-Seats, seat belts and supplemental restraint system1-83

When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. For additional infor-
mation, refer to "Supplemental air bag
warning light" in this section. If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner's
Manual.
