light NISSAN SENTRA 2015 B17 / 7.G User Guide

The ELR mode allows the seat belt to extend and
retract to allow the driver and passengers some
freedom of movement in the seat. The ELR locks
the seat belt when the vehicle slows down rapidly
or during certain impacts.
The ALR mode (child restraint mode) locks the
seat belt for child restraint installation.
When the ALR mode is activated, the seat belt
cannot be extended again until the seat belt
tongue is detached from the buckle and fully
retracted. The seat belt returns to the ELR mode
after the seat belt fully retracts. For additional
information, refer to “Child restraints” in this sec-
tion.
The ALR mode should be used only for
child restraint installation. During normal
seat belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt ten-
sion. It can also change the operation of
the front passenger air bag. For additional
information, refer to “Supplemental air bag
warning light” in this section.WARNING
When fastening the seat belts, be certain
that the seatbacks are completely secured
in the latched position. If they are not
completely secured, passengers may be
injured in an accident or sudden stop.
Unfastening the seat belts
To unfasten the seat belt, press the button on the
buckle
1. The seat belt automatically retracts.
Checking seat belt operation
Seat belt retractors are designed to lock seat belt
movement by two separate methods:● When the seat belt is pulled quickly from the
retractor
● When the vehicle slows down rapidly

1over the
seatback.
2. Secure the tether strap to the tether anchor point
2on the rear-parcel shelf behind the
child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove any
slack.
If you have any questions when installing a
top tether strap, consult a NISSAN dealer
for details.
WARNING
Child restraint anchorages are designed
to withstand only those loads imposed by
correctly fitted child restraints. Under no
circumstances are they to be used to at-
tach adult seat belts, or other items or
equipment to the vehicle. Doing so could
damage the child restraint anchorages.
The child restraint will not be properly
installed using the damaged anchorage,
and a child could be seriously injured or
killed in a collision.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
Locking Retractor (ALR) must be used
when installing a child restraint. Failure to
use the ALR mode will result in the child
restraint not being properly secured. The
restraint could tip over or be loose and
cause injury to a child in a sudden stop or
collision. Also, it can change the operation
of the front passenger air bag. For addi-
tional information, refer to “Supplemental
air bag warning light” in this section. For additional information, refer to all Warnings
and Cautions in the “Child safety” and “Child
restraint” sections of this manual before installing
a child restraint.
Do not use the lower anchors if the combined
weight of the child and the child restraint exceeds
65 lbs (29.5 kg) . If the combined weight of the
child and the child restraint is greater than 65 lbs
(29.5 kg) , use the vehicle’s seat belt (not the
lower anchors) to install the child restraint. Be
sure to follow the child restraint manufacturer’s
instructions for installation.

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.

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

the seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always properly use the
seat belts.
● The 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 as
needed. Failure 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 sensor
(weight sensor) that turns the front pas-
senger air bag OFF under some condi-
tions. 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 information, refer to
“Front Passenger air bag and status
light” in this section.
● Keep 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 front
air bag inflates.

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.
LRS0865
1-46Safety—Seats, seat belts and supplemental restraint system

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 applied to the front
passenger seat. The status of the front passen-
ger air bag (ON or OFF) is indicated by the front
passenger air bag status light
which is
located on the instrument panel.
After the ignition switch is placed in the ON
position, the front passenger air bag status light
on the instrument panel illuminates for about
7 seconds and then turns off or remains illumi-
nated depending on the front passenger seat
occupied status. The light operates as follows:
● Unoccupied front passenger’s seat:
The
light is OFF and the front passen-
ger air bag is OFF and will not inflate in a
crash.
● Front passenger seat occupied by a small
adult, child or child restraint as outlined in
this section: The
light illuminates to
indicate that the front passenger air bag is
OFF and will not inflate in a crash.
● Occupied front passenger seat and the pas-
senger meets the conditions as outlined in
this section: The
light is OFF to indi-
cate that the front passenger air bag is op-
erational. In addition to the above, certain objects placed
on the front passenger seat may also cause the
light to operate as described above depending
on their weight.
For additional information related to the normal
operation and troubleshooting of this occupant
classification sensor system, please refer to
“Normal operation” and “Troubleshooting” in this
section.
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.
The occupant classification sensor in this vehicle
is a weight sensor. It is designed to detect an
occupant and objects on the seat by weight. For
example, if a child is in the front passenger seat,
the NISSAN Advanced Air Bag System is de- signed to turn the front passenger air bag OFF in
accordance with the regulations. Also, if a child
restraint of the type specified in the regulations is
on the seat, its weight and the child’s weight can
be detected and cause the air bag to turn OFF.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the front
passenger 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 cushion (for example, by not sitting up-
right, 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. Always be
sure to be seated and wearing the seat belt
properly 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 is 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 ALR mode may
allow the restraint to tip or move in a collision or
sudden stop. This can also result in the passen-
Safety—Seats, seat belts and supplemental restraint system1-47

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.
