3. The booster seat should be positionedon the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
high back booster seat fit. If the head
restraint/headrest is removed, store it in
a secure place. Be sure to reinstall the
head restraint/headrest when the
booster seat is removed. For additional
information about head restraint/
headrest adjustment, removal and in-
stallation, see "Head restraints/
headrests" (P. 1-8). If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper booster
seat fit, try another seating position or a
different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure
to follow the booster seat manufactur-
er’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up ex-
tra slack. Be sure the shoulder belt is
positioned across the top, middle por-
tion of the child’s shoulder. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” (P. 1-15). 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in the ON position. The front passenger
air bag status light
may or may not
illuminate, depending on the size of the
child and the type of booster seat being
used. For additional information, see
“Front passenger air bag and status
light” (P. 1-57).

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
• Rear outboard seat-mounted side- impact supplemental air bag
• Roof-mounted curtain side-impact and rollover supplemental air bag
• Driver and front passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front and rear outboard seats)
Supplemental front-impact air bag
system
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
impacted.
Rear outboard seat-mounted side-
impact supplemental air bag system
This system can help cushion the impact
force to the chest area of the rear outboard
seat passengers in certain side-impact
collisions. The side air bags are designed to
inflate on the side where the vehicle is
impacted.
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.Driver and front passenger supplemen-
tal knee air bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.
The SRS is designed to
supplementthe
crash protection provided by the driver and
front passenger and rear 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, see “Seat belts” (P. 1-12).
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 system1-47

WARNING
• The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity 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 and front
passenger knee air bag will not in-
flate if the passenger air bag status
light is lit. For additional information,
see “Front passenger air bag and sta-
tus light” (P. 1-57). •
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 (weight sensor) that turns the
front passenger air bag and passen-
ger knee 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 infor-
mation, see “Front passenger air bag
and status light” (P. 1-57).
• 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.

ously injure or kill your child. For ad-
ditional information, see “Child re-
straints” (P. 1-23).WARNING
Front and rear outboard seat-mounted
side-impact supplemental air bags and
roof-mounted curtain side-impact and
rollover 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.
ARS1045ARS1046WRS0431
Safety-Seats, seat belts and supplemental restraint system1-51

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 with both feet on
the floor. 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 and
rear 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 window
or lean against the door. Some ex-
amples 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 or
rear seatbacks. They may interfere
with side air bag inflation.

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
seat 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/headrest or in the
seatback pocket.
• Make sure that there is nothing
pressing against the rear of the seat-
back, such as a child restraint in-
stalled 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 re-
straint does contact the instrument
panel, the system may determine the
seat is occupied and the passenger
air bag and front passenger supple-
mental knee air bag may deploy in a
collision. Also the front passenger air
bag status light may not illuminate.
For additional information about in-
stalling and using child restraints,
see "Child restraints" (P. 1-23).
• 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
occupant 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 oc-
cupant classification system is work-
ing 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 sta-
tus light may illuminate and the
supplemental 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.
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 dash-
board 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 inflate in certain fron-
tal collisions. Vehicle damage (or lack of it) is
not always an indication of proper front air
bag system operation.
Safety-Seats, seat belts and supplemental restraint system1-55

The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensors and occupant classifi-
cation 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 and
front passenger supplemental knee air
bag may be automatically turned off under
some conditions, depending on the weight
detected on the front passenger seat and
how the seat belt is used. If the front pas-
senger air bag and front passenger
supplemental knee air bag are OFF, the
front passenger air bag status light will be
illuminated. For additional information, see
“Front passenger air bag and status light”
(P. 1-57). 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.
The front 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.

light
WARNING
The front passenger air bag and front
passenger supplemental knee air bag
are designed to automatically turn OFF
under some conditions. Read this sec-
tion carefully to learn how it operates.
Proper use of the seat, seat belt, and
child restraints is necessary for most
effective protection. Failure to follow all
instructions in this manual concerning
the use of seats, seat belts, and child
restraints can increase the risk or se-
verity 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 and front passenger supplemental
knee air bag on or off depending on the
weight applied to the front passenger seat.
The status of the front passenger air bag
and front passengers supplemental knee
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 DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE 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, see “Normal op-
eration” (P. 1-59) and “Troubleshooting”
(P. 1-60).
