2018 NISSAN VERSA SEDAN warning

damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.
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 sensors are also monitored. Based
on information from the sensors, only one
front air bag may inflate in a crash, depend-
ing on the crash severity and whether the
front occupants are belted or unbelted. Ad-
ditionally, the front passenger air bag may
be automatically turned OFF under some
conditions, depending on the weight de-
tected on the front passenger seat and
how the seat belt is used. If the front pas-
senger air bag is OFF, the front passenger
air bag status light will be illuminated (if the
seat is unoccupied, the light will not be illu-
minated, but the air bag will be off ). For
additional information, refer to “Front pas-
senger air bag and status light” in this sec-
tion. One front air bag inflating does not
indicate improper performance of the sys-
tem.If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer. 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 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 in-
flate quickly in order to help protect thefront 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 af ter a
collision.
The front air bags operate only when the
ignition switch is placed in the ON posi-
tion.
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.

Front passenger air bag and status light
WARNING
The front passenger air bag is designed
to automatically turn OFF under some
conditions. Read this section carefully
to learn how it operates. Proper use of
the seat, seat belt and child restraints is
necessary for most effective protec-
tion. Failure 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
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 ap-
plied to the front passenger seat. The sta-
tus of the front passenger 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:
∙ Unoccupied front passenger’s seat:
The
light is OFF and the front pas-
senger 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
passenger meets the conditions as
outlined in this section: The
light is
OFF to indicate that the front passen-
ger air bag is operational.
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 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
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. 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 requir-
WRS0475
Safety—Seats, seat belts and supplemental restraint system1-51

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 system is
OFF by using a special tool. However, until
you have confirmed with a 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 passenger seat status. For ex-
ample, 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 passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will blink. 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 classif y the front passen-
ger based on weight, please follow the pre-
cautions and steps outlined below:
Precautions
∙ Make sure that there are no objects
weighing over 9.1 lbs. (4 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
pushing or pulling on the back of the
front passenger seat.
∙ Make sure that the front passenger
seat or seatback is not forced back
against an object 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, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended 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.
4. Remain in this position for 30 seconds
allowing the system to classif y the
front passenger before the vehicle is
put into motion.
5. Ensure proper classification by check-
ing the front passenger air bag status
light.
Safety—Seats, seat belts and supplemental restraint system1-53

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. Re-
start 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 af ter this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
3. If the light is OFF with a small adult,
child or child restraint occupying the
front passenger seat.
This may be due to the following con-
ditions that may be interfering with the
weight sensors:
∙ Small adult or child is not sitting upright,
leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.∙ The child restraint is not properly in-
stalled, as outlined in the “Child re-
straints” section of this manual.
∙ An object weighing over 9.1 lbs. (4 kg)
hanging 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 pas-
senger 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. Re-
start 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 af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.

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 cur-
tain air bags are located in the side roof
rails.All of the information, cautions, and
warnings in this manual apply and 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 colli-sion are similar to those of a higher severity
side impact. They are designed to inflate on
the side where the vehicle is impacted.
They may not inflate in certain side colli-
sions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (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 condition
should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest of the front occupants. Curtain
air bags help to cushion the impact force to
the head of occupants in the front and rear
outboard seating positions. They can help
save lives and reduce serious injuries. How-ever, an inflating side air bag or 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 up-
right 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 occupants. Be-
cause of this, the force of the side air bags
and curtain air bags inflating can increase
the risk of injury if the occupant is too close
to, or is against, these air bag modules dur-
ing inflation. The side air bag will deflate
quickly af ter the collision is over.
The curtain air bags will remain inflated for
a short time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON or START 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.

WARNING
∙ Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door fin-
isher and the front seat. Such objects
may become dangerous projectiles
and cause injury if a side air bag
inflates.
∙ Right af ter inflation, several side air
bag and curtain air bag system com-
ponents 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 systems.
∙ Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
curtain air bag systems.∙ Tampering with the side air bag sys-
tem may result in serious personal in-
jury. For example, do not change the
front seats by placing material near
the seatbacks or by installing addi-
tional trim material, such as seat cov-
ers, around the side air bag.
∙ Work around and on the side air bag
and curtain air bag systems should be
done by a NISSAN dealer. Installation
of electrical equipment should also be
done by a NISSAN dealer. The SRS wir-
ing 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 or connectors
are yellow or orange for easy identifica-
tion.
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.
Seat belt with pretensioner(s)
(front seats)
WARNING
∙ The pretensioner(s) cannot be reused
af ter activation. They must be re-
placed together with the retractor
and buckle as a unit.
∙ If the vehicle becomes involved in a
collision but pretensioner(s) are not
activated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit a NISSAN dealer for this
service.
∙ No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental acti-
vation of the pretensioner(s). Tamper-
ing with the pretensioner system may
result in serious personal injury.
1-58Safety—Seats, seat belts and supplemental restraint system

∙ It is recommended that you visit a
NISSAN dealer for work around and on
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical
test equipment and probing devices
should not be used on the preten-
sioner system.
∙ If you need to dispose of the preten-
sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with the
seat belt retractor, the pretensioner(s) help
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants.
The pretensioner(s) are encased with the
seat belt retractor. These seat belts are
used the same way as conventional seat
belts.When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
The supplemental air bag warning
light
is used to indicate malfunctions
in the pretensioner(s) system. For addi-
tional information, refer to “Supplemental
air bag warning light” in this section. If the
operation of the supplemental air bag
warning light indicates there is a malfunc-
tion, have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s
Manual.
