PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
• Driver and front passenger supplementalfront-impact air bag (NISSAN Advanced
Air Bag System)
• Front seat-mounted side-impact supple- mental 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.
LRS0539
SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)

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

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
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
• The front passenger seat is equipped
with an occupant classification sen-
sor (pressure sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be prop-
erly seated and wearing the seat belt
can increase the risk or severity of
injury in an accident. For additional
information, refer to “Front passen-
ger 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
• Even with the NISSAN Advanced Air
Bag System, never install a rear-
facing child restraint in the front seat.
An inflating front air bag could seri-
ously injure or kill your child. For ad-
ditional information, refer to “Child
restraints” in this section.

WARNING
Front seat-mounted side-impact
supplemental air bags and roof-
mounted curtain side-impact and roll-
over supplemental air bags:
• The side air bags and curtain air bags
ordinarily will not inflate in the event
of a frontal impact, rear impact, or
lower severity side collision. Always
wear your seat belts to help reduce
the risk or severity of injury in various
kinds of accidents.

WARNING
• The seat belts, the side air bags and
curtain air bags are most effective
when you are sitting well back and
upright in the seat. The side air bag
and curtain air bag inflate 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 or near the side roof
rails. Do not allow anyone sitting in
the front seats or rear outboard seats
to extend their hand out of the win-
dow or lean against the door. Some
examples of dangerous riding posi-
tions are shown in the previous
illustrations.
WARNING
• When 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 espe-
cially careful with children, who
should always be properly re-
strained. Some examples of danger-
ous riding positions are shown in the
illustrations.
• Do not use seat covers on the front
seatbacks. They may interfere with
side air bag inflation.

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.
