2007 NISSAN SENTRA light

cNISSAN recommends that child re-
straints be installed in the rear seat.
However, if you must install a forward
facing child restraint in the front pas-
senger seat, move the passenger seat
to the rearmost position. Also, be sure
the front passenger air bag status light
is illuminated to indicate the passenger
air bag is OFF. See “Front passenger air
bag and status light” later in this sec-
tion for details.
cThe three-point seat belt in your vehicle
is equipped with an automatic locking
mode retractor which must be used
when installing a child restraint.
cFailure to use the retractor’s locking
mode will result in the child restraint
not being properly secured. The re-
straint could tip over or otherwise be
unsecured and cause injury to the child
in a sudden stop or collision. Also, it can
change the operation of the front pas-
senger air bag. See “Front passenger
air bag and status light” later in this
section.
cA child restraint with a top tether strap
should not be used in the front passen-
ger seat.The instructions in this section apply to child
restraint installation using the vehicle seat belts in
the rear seat or the front passenger seat.
1.If you must install a child restraint in
the front seat, it should be placed in a
front-facing direction only. Move the
seat to the rearmost position. Child
restraints for infants must be used in
the rear-facing direction and therefore
must not be used in the front seat.
2. Position the child restraint on the seat. Al-
ways follow the child restraint manufactur-
er’s instructions
The back of the child restraint should be secured
against the vehicle seatback. If necessary, adjust
or remove the head restraint to obtain the correct
child restraint fit. See “Head restraint adjust-
ment” in this section.
If the head restraint is removed, store it in a
secure place. Be sure to install the head restraint
when the child restraint is removed. If the seating
position does not have an adjustable head re-
straint and it is interfering with the proper child
restraint fit, try another seating position or a dif-
ferent child restraint.3. Route the seat belt tongue through the child
restraint and insert it into the buckle until you
hear and feel the latch engage. Be sure to
follow the child restraint manufacturer’s in-
structions for belt routing.

7. If the child restraint is equipped with a top
tether strap, route the top tether strap and
secure the tether strap to the tether anchor
point (rear seat installation only) . See “Top
tether strap child restraint” in this section.
Do not install child restraints that require the
use of a top tether strap to seating positions
that do not have a top tether anchor.8. Before placing the child in the child restraint,
hold the child restraint near the seat belt
path and use force to push the child restraint
from side to side, and tug it forward to make
sure that it is securely held in place. It should
not move more than 1 in (25 mm) . If it does
move more than 1 in (25 mm) , pull again on
the shoulder belt to further tighten the child
restraint. If you are unable to properly secure
the restraint, move the restraint to another
seating position and try again, or try a differ-
ent child restraint. Not all child restraints fit in
all types of vehicles.
9. Check that the retractor is in the automatic
locking mode by trying to pull more seat belt
out of the retractor. If you cannot pull any
more belt webbing out of the retractor, the
retractor is in the automatic locking mode.
10. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 3
through 8.11. If the child restraint is installed in the front
passenger seat, turn the ignition switch to
the ON position. The front passenger air bag
status light
orshould illumi-
nate. If this light is not illuminated see9Front

other seating position.Have the system
checked by a NISSAN dealer.
After the child restraint is removed and the seat
belt is fully retracted, the automatic locking mode

PRECAUTIONS ON
SUPPLEMENTAL RESTRAINT
SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the driver and passenger supplemental front air
bags (NISSAN Advanced Air Bag System) ,
supplemental side air bags, curtain side-impact
air bags and pre-tensioner seat belts.
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.
Supplemental side-impact air bag system:
This system can help cushion the impact force to
the chest and pelvic area of the driver and front
passenger in certain side impact collisions. The
front seat side-impact supplemental side air bags
are designed to inflate on the side where the
vehicle is impacted.
Supplemental curtain side-impact air bag
system:This system can help cushion the im-
pact force to the head of occupants in front and
rear outboard seating positions in certain side
impact collisions. The curtain side-impact air
bags are designed to inflate on the side where
the vehicle is impacted.

These supplemental restraint systems are de-
signed tosupplementthe crash protection pro-
vided by the driver and front passenger seat belts
and arenot a substitutefor them. Seat belts
should always be correctly worn and the occu-
pant seated a suitable distance away from the
steering wheel, instrument panel and door finish-
ers. (See “Seat belts” earlier in this section for
instructions and precautions on seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
WARNING
cThe supplemental front air bags ordi-
narily will not inflate 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.
cThe front passenger air bag will not
inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. See “Front passenger air
bag and status light” later in this
section.cThe seat belts and the supplemental
front air bags are most effective when
you are sitting 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 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 supplemental
front air bag if you are up against it
when it inflates. Always sit back against

the seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always use the seat belts.
cThe driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
advanced air bag system monitors the
severity of a collision and seat belt us-
age then inflates the air bags. Failure to
properly wear seat belts can increase
the risk or severity of injury in an
accident.
cThe front passenger seat is equipped
with an occupant classification sensor
(pressure 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 acci-
dent. See “Front Passenger air bag and
status light” later in this section.
cKeep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the
supplemental front air bag inflates.

NISSAN Advanced Air Bag System
(front seats)
This vehicle is equipped with the NISSAN ad-
vanced air bag system for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S. regu-
lations. It is also permitted in Canada.However,
all of the information, cautions and warn-
ings in this manual still apply and must be
followed.
The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box. The supplemen-
tal front air bags are designed to inflate in higher
severity frontal collisions, although they may in-
flate if the forces in another type of collision are
similar to those of a higher severity frontal impact.They may not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always an
indication of proper supplemental front air bag
system operation.
The NISSAN advanced air bag system has dual
stage inflators. It also monitors information from
the crash zone sensor, the diagnosis sensor unit,
seat belt buckle sensors, occupant classification
sensor (pressure sensor) and passenger seat
belt tension sensor. Inflator operation 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 informa-
tion 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. Additionally, the front passenger air
bag may be automatically turned OFF under
some conditions, depending on the weight de-
tected on the passenger seat and how the seat
belt is used. If the front passenger air bag is OFF,
the passenger air bag status light will be illumi-
nated (if the seat is unoccupied, the light will not
be illuminated, but the air bag will be off) . See
“Front passenger air bag and status light” later in
this section for further details. One front air bag
inflating does not indicate improper performance
of the system.If you have any questions about your air bag
system, please contact NISSAN or your NISSAN
dealer. If you are considering modification of your
vehicle due to a disability, you may also contact
NISSAN. Contact information is contained in the
front of this Owner’s Manual.
When a supplemental front 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. Care should be taken to
not inhale it, as it may cause irritation and chok-
ing. Those with a history of a breathing condition
should get fresh air promptly.
Supplemental 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 serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air bags
do not provide restraint to the lower body.
Even with NISSAN advanced air bags, seat belts
should be correctly worn and the driver and pas-
senger seated upright as far as practical away
from the steering wheel or instrument panel. The
supplemental 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

increase 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 after a collision.
The supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after 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 con-
ditions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt and child restraints is nec-
essary for most effective protection. Fail-
ure 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

cOccupied passenger seat and the passen-

tion: The light
oris OFF to in-
dicate that the front passenger air bag is
operational.
Front passenger air bag
The front passenger air bag is designed to auto-
matically turn OFF when the vehicle is operated
under some conditions as described below in
accordance with U.S. regulations. If the front
passenger air bag is OFF, it will not inflate in a
crash. The driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help reduce
the risk of injury or death from an inflating air bag
to certain front passenger seat occupants, such
as children, by requiring the air bag to be auto-
matically turned OFF. Certain sensors are used
to meet the requirements.
One sensor used is the occupant classification
sensor (pressure sensor) . It is in the bottom of the
front passenger seat cushion and is designed to
detect an occupant and objects on the seat by
weight. It works together with seat belt sensors
described later. For example, if a child is in the
front passenger seat, the advanced air bag sys-
tem is designed to turn the passenger air bag
OFF in accordance with the regulations. Also, if a
child restraint of the type specified in the regula-tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the automatic locking mode (child restraint
mode) . Based on the weight on the seat detected
by the occupant classification sensor and the belt
tension detected on the seat belt, the advanced
air bag system determines whether the front pas-
senger air bag should be automatically turned
OFF as required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger air bag to be automatically turned OFF. For
small adults it may be turned OFF, however if the
occupant takes his/her weight off the seat cush-
ion (for example, by not sitting upright, by sitting
on an edge of the seat, or by otherwise being out
of position) , this could cause the sensor to turn
the air bag OFF. In addition, if the occupant
improperly uses the seat belt in the automatic
locking mode (child restraint mode) , this could
cause the air bag to be turned OFF. Always be
sure to be seated and wearing the seat beltproperly for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the automatic locking mode (child restraint
mode) may allow the restraint to tip or move in an
accident or sudden stop. This can also result in
the passenger air bag inflating in a crash instead
of being OFF. See “Child restraints” earlier in this
section for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object’s weight detected by the occupant
classification sensor. Other conditions could also
result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.
