2017 NISSAN SENTRA warning

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 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 examples
of dangerous riding positions 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 especially careful
with children, who should always be
properly restrained. Some examples of
dangerous riding positions are shown
in the illustrations.
● Do not use seat covers on the front
seatbacks. They may interfere with side
air bag inflation.

To ensure proper operation of the passen-
ger’s NISSAN Advanced Air bag System,
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
2.2 lbs (1 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
● Make sure that there is nothing press-
ing against the rear of the seatback,
such as a child restraint installed in the
rear seat or an object stored on the
floor.
● 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 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 about in-
stalling and using child restraints, refer
to “Child restraints” in this section.
● 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, get the occupant
classification system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.
● Until you have confirmed with a dealer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions.
1-48Safety—Seats, seat belts and supplemental restraint system

●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.
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
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 inflate in certain frontal
collisions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag sys-
tem operation.
The NISSAN Advanced Air Bag System monitors
information from the crash zone sensor, the Air bag Control Unit (ACU) . Inflator operation is
based on the severity of a collision and seat belt
usage for the driver. For the front passenger, the
occupant classification 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 occu-
pants are belted or unbelted. Additionally, the
front passenger 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 passen-
ger air bag is OFF, the passenger air bag status
light will be illuminated. For additional informa-
tion, 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, 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 disability, you may also
contact NISSAN. Contact information is con-
tained 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 maycause 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
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 increase
the risk of injury if the occupant is too close to, or
is against, the front air bag module during infla-
tion.
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.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 lo-
cated 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:
CONDITION DESCRIPTIONPASSENGER AIR BAG INDI-
CATOR LIGHT () FRONT PASSENGER 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 described above depending
on their weight.
For additional information related to the normal
operation and troubleshooting of this occupantclassification 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 operatedunder 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.
WRS0475
1-50Safety—Seats, seat belts and supplemental restraint system

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 be illuminated (blink-
ing or steadily lit) . Have the system checked. It is
recommended that you visit a NISSAN dealer for
this service.
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.
Steps 1. Adjust the seat as outlined in the “Seats” section of this manual. Sit upright, leaning
against the seatback, and centered on the
seat cushion with your feet comfortably ex-
tended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual. Front passen-
ger seat belt buckle status is monitored by
the occupant classification system, and is
used as an input to determine occupancy
status. So, it is highly recommended that the
front passenger fasten their seat belt.
4. Remain in this position for 30 seconds al- lowing the system to classify the front pas-
senger before the vehicle is put into motion.
5. Ensure proper classification by checking the front passenger air bag status light. NOTE:
This vehicle’s occupant classification sen-
sor system generally keeps the classifica-
tion locked during driving, so it is important
that you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor
may recalculate the weight of the occupant
under some conditions (both while driving
and when stopped) , so front passenger
seat occupants should continue to remain
seated as outlined above.
Troubleshooting
If you think the front passenger air bag status light
is incorrect:
1. If the light is ON with an adult occupying the front passenger seat:
● Occupant is a small adult — the air bag light
is functioning as intended. The front passen-
ger air bag is suppressed.
However, if the occupant is not a small adult, then
this may be due to the following conditions that
may be interfering with the weight sensors: ● Occupant is not sitting upright, leaning
against the seatback, and centered on the
seat cushion with his/her feet comfortably
extended to the floor.

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.
● No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
● Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the front air bag system. ●
Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and above
the instrument panel or by installing
additional trim material around the air
bag system.
● Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious
personal injury.
● Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classification
sensor (weight sensor) . ●
No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
front air bag system. Tampering with
the seat belt system may result in seri-
ous personal injury.
● It is recommended that you visit a
NISSAN dealer for work on and around
the front air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equipment.
The Supplemental Restraint System
(SRS) wiring harnesses* should not be
modified or disconnected. Unauthor-
ized electrical test equipment and prob-
ing devices should not be used on the
air bag system.
● A cracked windshield should be re-
placed immediately by a qualified repair
facility. A cracked windshield could af-
fect the function of the supplemental air
bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the front air bag system
and guide the buyer to the appropriate sections
in this Owner’s Manual.
1-54Safety—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.

WARNING
●Do not place any objects near the seat-
back of the front seats. Also, do not
place any objects (an umbrella, bag,
etc.) between the front door finisher
and the front seat. Such objects may
become dangerous projectiles and
cause injury if a side air bag inflates.
● Right after inflation, several side air bag
and curtain air bag system components
will be hot. Do not touch them; you may
severely burn yourself.
● No unauthorized changes should be
made to any components or wiring of
the side air bag and curtain air bag
systems. This is to prevent damage to or
accidental inflation of the side air bag
and curtain air bag or damage to the
side air bag and curtain air bag systems.
● Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the
side air bag and curtain air bag systems. ●
Tampering with the side air bag system
may result in serious personal injury.
For example, do not change the front
seats by placing material near the seat-
backs or by installing additional trim
material, such as seat covers, around
the side air bag.
● It is recommended that you visit a
NISSAN dealer for work on and around
the side air bag and curtain air bag
systems. It is also recommended that
you visit a NISSAN dealer for installa-
tion of electrical equipment. The SRS
wiring harnesses* should not be modi-
fied or disconnected. Unauthorized
electrical test equipment and probing
devices should not be used on the side
air bag or curtain air bag systems.
*The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the side air bag and
curtain air bag systems and guide the buyer to
the appropriate sections in this Owner’s Manual.
