2015 NISSAN SENTRA warning light

8. After attaching the child restraint, test it be-fore you place the child in it. Push it from side
to side while holding the child restraint near
the seat belt path. The child restraint should
not move more than 1 inch (25 mm) , from
side to side. Try to tug it forward and check
to see if the belt holds the restraint in place.
If the restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may need
to try a different child restraint. Not all child
restraints fit in all types of vehicles. 9. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 2
through 8.
10. If the child restraint is installed in the frontpassenger seat, place the ignition switch in
the ON position. The front passenger air bag
status light
should illuminate. If this
light is not illuminated, refer to “Supplemen-
tal air bag warning light” in this section.
Move the child restraint to another
seating position. Have the system
checked by a NISSAN dealer.
After the child restraint is removed and the seat
belt is fully retracted, the ALR mode (child re-
straint mode) is canceled.

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 manufacturer’s in-
structions for adjusting the seat belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up extra slack.
Be sure the shoulder belt is positioned
across the top, middle portion 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 instruc- tions for properly fastening a seat belt
shown in “Three-point type seat belt with
retractor” in this section. 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 addi-
tional information, refer to “Front passenger
air bag and status light” in this section.
PRECAUTIONS ON SRS
This SRS section contains important information
concerning the following systems:
● Driver and passenger supplemental front-
impact air bag (NISSAN Advanced Air Bag
System)
● Front seat-mounted side-impact supple-
mental air bag
● Roof-mounted curtain side-impact and roll-
over supplemental air bag
● Seat belt with pretensioner
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 supple-
mental 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 collisions. The side air bags
are designed to inflate on the side where the
vehicle is impacted.
WRS0475
SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
Safety—Seats, seat belts and supplemental restraint system1-37

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 the outboard seating
positions in certain side-impact or rollover colli-
sions. In a side impact, the curtain air bags are
designed to inflate on the side where the vehicle
is impacted. In a rollover, curtain air bags on both
sides are designed to inflate and remain inflated
for a short time.
The SRS is designed tosupplementthe crash
protection provided by the driver and front pas-
senger seat belts and is not a substitutefor
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 information,
refer to “Seat belts” 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 posi-
tion.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
WARNING
● The front air bags ordinarily will not
inflate 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 sitting well
back and upright in the seat. The front
air bags inflate with great force. Even
with the NISSAN Advanced Air Bag Sys-
tem, if you are unrestrained, leaning
forward, sitting sideways or out of posi-
tion 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
WRS0031
1-38Safety—Seats, seat belts and supplemental restraint system

WARNING
To ensure proper operation of the passen-
ger’s advanced air bag system, please ob-
serve 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
2.2 lb (1 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
● Do not store luggage behind the seat
that can press into the seatback.
● 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 supplemental
air bag warning light may flash. ●
If a forward facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem 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 information, refer to
“Child restraints” in this section for in-
formation about installing and using
child restraints.
● 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 de-
scribed in this section, please take your
vehicle to your NISSAN dealer to check
the occupant classification system.
● Until you have confirmed with your
dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in the
rear seating positions.
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.
All of the
information, cautions and warnings in this
manual must be followed.
The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
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 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 front air bag system opera-
tion.
The NISSAN Advanced Air Bag System has dual
stage inflators. It also monitors information from
the crash zone sensor, the Air bag Control Unit
(ACU) , seat belt buckle sensors and occupant
classification sensor (weight sensor) . Inflator op-
eration is based on the severity of a collision and
seat belt usage for the driver. For the front pas-
senger, the occupant classification sensors are
also monitored. Based on information 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 un-
belted. Additionally, the front passenger air bag
may be automatically turned off under some con-
Safety—Seats, seat belts and supplemental restraint system1-45

ditions, depending on the weight detected 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 illuminated (if the seat is
unoccupied, the light will not be illuminated, but
the air bag will be off) . For additional information,
refer to “Front passenger 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, 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 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 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 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
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 front air bags operate only when the
ignition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds 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 condi-
tions. Read this section 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 con-
cerning the use of seats, seat belts and
child restraints can increase the risk or
severity of injury in an accident.

ger air bag inflating in a crash instead of being
OFF. For additional information about proper use
and installation, refer to “Child restraints” in this
section.
If the front passenger seat is not occupied, the
front 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.
Using the front passenger air bag status light, you
can monitor when the front passenger air bag is
automatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the front
passenger air bag status light is illuminated (indi-
cating 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 beingused. 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 properly and the occupant is posi-
tioned properly. If the air bag status light is still not
illuminated, reposition the occupant or child re-
straint 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 sys-
tem is OFF by using a special tool. However, until
you have confirmed with your 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 passen-
ger seat status. For example, if a large adult who
is sitting in the front passenger seat exits the
vehicle, the front passenger 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 passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
of the instrument panel, will blink. Have the sys-
tem checked by a NISSAN dealer.
Normal operation
In order for the occupant classification sensor
system to classify the front passenger based on
weight, please follow the precautions and steps
outlined below:
Precautions
● Make sure that there are no objects weigh-
ing over 2.2 lbs (1 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 push-
ing or pulling on the back of the front pas-
senger seat.
● Make sure that the front passenger seat or
seatback is not forced back against an ob-
ject on the seat or floor behind it.
● Make sure that there is no object placed
under the front passenger seat.
1-48Safety—Seats, seat belts and supplemental restraint system

●An object placed under the front passenger
seat.
● An object placed between the seat cushion
and center console or between the seat
cushion and the door.
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. Restart 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 ON after this, the person should
be advised not to ride in the front passenger seat
and the vehicle should be checked by a NISSAN
dealer as soon as possible. 3. If the light is OFF with a small adult, child or child restraint occupying the front passen-
ger seat.
This may be due to the following conditions
that may be interfering with the weight sen-
sors: ●
Small adult or child is not sitting upright,
leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
● The child restraint is not properly installed,
as outlined in the “Child restraints” section of
this manual.
● An object weighing over 2.2 lbs (1 kg) hang-
ing on the seat or placed in the seatback
pocket.
● A child restraint or other object pressing
against 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 passenger
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. Restart 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 after this, the small adult,
child or child restraint should be repositioned in
the rear seat and the vehicle should be checked
by a NISSAN dealer as soon as possible.
Other supplemental front-impact air bag
precautions
WARNING
●
Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause
injury if the front air bags inflate.
● Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
1-50Safety—Seats, seat belts and supplemental restraint system

Front seat-mounted side-impact
supplemental air bag and roof-
mounted curtain side-impact and
rollover supplemental air bag systems
The side air bags are located in the outside of the
seatback of the front seats. The curtain air bags
are located in the side roof rails.All of the
information, cautions and warnings in this
manual must be followed. The side air bags
and curtain air bags are designed to inflate in
higher severity side collisions, although they may
inflate if the forces in another type of collision 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 cer-
tain 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 con-
dition 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 occupants. Curtain air
bags help to cushion the impact force to the head
of occupants in the front and rear outboard seat-
ing positions. They can help save lives and re-
duce serious injuries. However, an inflating side
air bag and 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 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 front and rear
outboard occupants. Because 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
during inflation. The side air bag and will deflate
quickly after the collision is over.
The curtain air bag will remain inflated for a short
time.
The side air bags and curtain air bags op-
erate only when the ignition switch is
placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
