PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:∙ Driver and front passenger supplemen- tal front-impact air bag (NISSAN Ad-
vanced Air Bag System)
∙ Front seat-mounted side-impact supplemental air bag
∙ Roof-mounted curtain side-impact and rollover supplemental air bag
∙ Seat belt with pretensioner(s) (front seats)
Supplemental front-impact air bag sys-
tem
The NISSAN Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact
supplemental air bag system
This system can help cushion the impact
force to the chest area of the driver and
front passenger in certain side-impact col-
lisions. The side air bags are designed to
inflate on the side where the vehicle is im-
pacted. 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 collisions. 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 to
supplementthe
crash protection provided by the driver and
front passenger seat belts and is not a
substitute for them. Seat belts should al-
ways be correctly worn and the occupant
seated a suitable distance away from the
steering wheel, instrument panel and door
finishers. For additional information, refer
to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is placed in the
ON 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.
SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
Safety—Seats, seat belts and supplemental restraint system1-43

WARNING
∙ The front air bags ordinarily will notinflate in the event of a side impact,
rear impact, rollover, or lower severity
frontal 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. For additional information,
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 Advanced
Air Bag System, if you are unre-
strained, leaning forward, sitting side-
ways or out of position in any way, you
are at greater risk of injury or death in
a crash. You may also receive 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 or instrument panel.
Always properly use the seat belts.
∙ The driver and front passenger seat belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The NISSAN Advanced Air
Bag System monitors the severity of a
collision and seat belt usage, then in-
flates the air bags as needed. Failure
to properly wear seat belts can in-
crease the risk or severity of injury in
an accident.
∙ The front passenger seat is equipped with an occupant classification sen-
sor (weight sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be properly
seated and wearing the seat belt can
increase the risk or severity of injury in
an accident. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.
∙ Keep hands on the outside of the steering wheel. Placing them inside
the steering wheel rim could increase
the risk that they are injured when the
front air bag inflates.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rear bench seats to push or pull on the
seatback pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 kg) on the seatback, head
restraint or in the seatback pocket. ∙ Make sure that there is nothing press-
ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.
∙ Make sure that there is no object placed under the front passenger
seat.
∙ Make sure that there is no object placed between the seat cushion and
center console or between the seat
cushion and the door.
∙ If a forward-facing child restraint is installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. For additional in-
formation, refer to “Child restraints” in
this section.
∙ Confirm the operating condition with the front passenger air bag status
light. ∙ If you notice that the front passenger
air bag status light is not operating as
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service.
∙ Until you have confirmed with a dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.
∙ Do not position the front passenger seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
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.
1-50Safety—Seats, seat belts and supplemental restraint system

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 and occupation classi-
fication sensor (weight sensor). Inflator op-
eration is based on the severity of a colli-
sion and seat belt usage for the driver. For
the front passenger, the occupant classifi-
cation sensor is also monitored. Based on
information from the sensor, 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 theseat belt is used. If the front passenger air
bag is OFF, the front passenger air bag sta-
tus light will be illuminated. For additional
information, refer to “Front passenger air
bag and status light” in this section. One
front air bag inflating does not indicate im-
proper 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.
The front air bags operate only when the
ignition switch is in the ON 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.

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 injury in
an accident.Status light
The front passenger seat is equipped with
an occupant classification sensor (weight
sensor) that turns the front passenger air
bag on or off depending on the weight ap-
plied to the front passenger seat. The sta-
tus of the front passenger air bag (ON or
OFF) is indicated by the front passenger air
bag status light
which is located on
the instrument panel.
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:
CONDITION DESCRIPTIONPASSENGER AIR BAG STA-
TUS LIGHT () FRONT PASSENGER AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
In addition to the above, certain objects
placed on the front passenger seat may
also cause the light to operate as de-
scribed above depending on their weight.For additional information, refer to “Normal
operation” and “Troubleshooting” in this
section.
Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-

pant is positioned properly. If the air bag
status light is still not illuminated, reposi-
tion 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, it is
recommended that you take your vehicle
to a NISSAN dealer. A NISSAN dealer can
check system status 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 front passenger seat status. This is nor-
mal system operation and does not indi-
cate 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 be illuminated (blinking or
steadily lit). Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service. Normal operation
In order for the occupant classification
sensor system to classif y the front passen-
ger based on weight, please follow the pre-
cautions and steps outlined below:
Precautions
∙ Make sure that there are no objects weighing over 9.1 lbs. (4 kg) hanging on
the seat or placed in the seatback
pocket.
∙ Make sure that a child restraint or other object is not pressing against the rear
of the seatback.
∙ Make sure that a rear passenger is not pushing or pulling on the back of the
front passenger seat.
∙ Make sure that the front passenger seat or seatback is not forced back
against an object on the seat or floor
behind it.
∙ Make sure that there is no object placed under the front passenger seat. Steps
1. Adjust the seat as outlined in the “Seats” section of this manual. Sit upright, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual.
Front passenger seat belt buckle sta-
tus is monitored by the occupant clas-
sification system, and is used as an in-
put to determine occupancy status. So,
it is highly recommended that the front
passenger fasten their seat belt.
4. Remain in this position for 30 seconds allowing the system to classif y the
front passenger before the vehicle is
put into motion.
5. Ensure proper classification by check- ing the front passenger air bag status
light.
1-54Safety—Seats, seat belts and supplemental restraint system

∙ A child restraint or other object pressingagainst the rear of the seatback.
∙ A rear passenger pushing or pulling on the back of the front passenger seat.
∙ Forcing the front seat or seatback against an object on the seat or floor
behind it.
∙ An object placed under the front pas- senger seat.
∙ An object placed between the seat cushion and center console.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service. 3. If the light is OFF with no front passen-
ger and no objects on the front pas-
senger seat, the vehicle should be
checked. It is recommended that you
visit a NISSAN dealer as soon as pos-
sible.
Other supplemental front-impact air
bag precautions
WARNING
∙ 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 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 damage
to the supplemental air bag system. ∙ Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury.
1-56Safety—Seats, seat belts and supplemental restraint system

other type of collision are similar to those of
a higher severity impact. They are de-
signed to inflate on the side where the ve-
hicle 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
rollovers. As a result, certain vehicle move-
ments (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 of the front occupants. Curtain
air bags help to cushion the impact force to
the head of occupants in the front and rear
outboard seating positions in all rows. They
can help save lives and reduce serious in-juries. However, an inflating side air bag or
curtain air bag may cause abrasions 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 front passenger seated
upright 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 bags
and curtain air bags 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 bag will remain inflated for a
short time.
The side air bags and curtain air bags
operate only when the ignition switch is
placed in the ON 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.
