2015 NISSAN ALTIMA light

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 a 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’s seat occupied by a small
adult, child or child restraint as outlined in
the Safety section of the owner’s manual:
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
the Safety section of the owner’s manual:
The
light is OFF to indicate that the
front passenger 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 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 ve-
hicle 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 Advanced Air Bag System 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 regulations is on the seat,
the Occupant Classification Sensors can detect
it and cause the air bag to turn OFF.
Front passenger seat adult occupants who are
properly seated and using the seat belt as outlined
in this manual should not cause the passenger air
bag to be automatically turned OFF. For small
adults it may be turned OFF, however if the occu-
pant takes his/her weight off the seat cushion (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. Always be sure to be seated and wearing
the seat belt properly for the most effective protec-
tion 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
Safety—Seats, seat belts and supplemental restraint system1-51

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-
ger air bag inflating in a crash instead of being
OFF. For additional information, refer to “Child
restraints” in this section for proper use and in-
stallation.
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.
Using the passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically 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 passen-
ger air bag status light is illuminated (indicating
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 passenger air bag status light may or may not
be illuminated, depending on the size of the child
and the type of child restraint being used. 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 positioned properly. If the air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate 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) . Your NISSAN dealer can check that the
system 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
passenger air bag status light will take a few
seconds to register a change in the passenger
seat status. For example, if a large adult who is
sitting in the front passenger seat exits the ve-
hicle, the passenger air bag status light will go
from OFF to ON for a few seconds and then toOFF. 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 system to
classify the right front passenger based on
weight, please follow the precautions and steps
outlined below:
Precautions
● Make sure there are no objects weighing
over 2.2 lbs (1 kg) hanging on the seat or
placed in the seatback pocket.
●
Make sure that a child seat 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’s seat.
● Make sure that the front 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’s seat.
1-52Safety—Seats, seat belts and supplemental restraint system

Steps1. Adjust the seat as outlined in the “Seats” section of the Owner’s Manual. Sit upright,
leaning against the seatback, and centered
on the seat cushion with your feet comfort-
ably extended to the floor.
2. Make sure there are no objects on the occu- pant’s lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of the Owner’s Manual.
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 sys-
tem locks the classification during driving
so it is important that you confirm that the
front passenger is properly classified prior
to driving. Also, the occupant classification
system may recalculate the weight of the
occupant when the vehicle comes to a stop
(i.e stop light, stop sign etc.) , so front pas-
senger 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 no front passenger and no objects on the front passenger seat:
This may be due to the following conditions that
may be interfering with the weight sensors: ● An object weighing over 2.2 lbs (1 kg) hang-
ing on the seat or placed in the seatback
pocket.
● A child seat or other object pressing against
the rear of the seatback.
● A rear passenger pushing or pulling on the
back of the front passenger’s seat.
● The front seat or seatback is forced back
against an object on the seat or floor behind
it.
● An object placed under the front passen-
ger’s seat.
● An object placed between the seat cushion
and center console or between door and
cushion.
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 one 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 vehicle should
be checked by a NISSAN dealer as soon as
possible.
2. 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 feet comfortably extended
to the floor.
● A child seat or other object pressing against
the rear of the seatback.
● A rear passenger pushing or pulling on the
back of the front passenger’s seat.
Safety—Seats, seat belts and supplemental restraint system1-53

●The front seat or seatback is forced back
against an object on the seat or floor behind
it.
● An object placed under the front passen-
ger’s 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 one 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 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 feet comfortably
extended to the floor.
● The child restraint is not properly installed,
as outlined in the “Child restraints” section of
the Owner’s Manual.
● An object weighing over 2.2 lbs (1 kg) hang-
ing on the seat or placed in the seatback
pocket.
● A child seat or other object pressing against
the rear of the seatback.
● A rear passenger pushing or pulling on the
back of the front passenger’s seat.
● The front seat or seatback is forced back
against an object on the seat or floor behind
it.
● An object placed under the front passen-
ger’s 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 one 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.
1-54Safety—Seats, seat belts and supplemental restraint system

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 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 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.
● Work around and on the side air bag
and curtain air bag system 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 modified
or disconnected. Unauthorized electri-
cal test equipment and probing devices
should not be used on the side air bag
or curtain 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 side air bag and
curtain air bag systems and guide the buyer to
the appropriate sections in this Owner’s Manual.

SEAT BELTS WITH
PRETENSIONERS (front seats)
WARNING
●The pretensioners cannot be reused af-
ter activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
collision but a pretensioner is not acti-
vated, be sure to have the pretensioner
system checked and, if necessary, re-
placed by your NISSAN dealer.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioners. Tampering with
the pretensioner system may result in
serious personal injury.
● Work around and on the pretensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system. ●
If you need to dispose of a pretensioner
or scrap the vehicle, contact a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury.
The pretensioner system may activate with the
supplemental air bag system in certain types of
collisions. Working with the seat belt retractor,
the pretensioners help tighten the seat belt when
the vehicle becomes involved in certain types of
collisions, helping to restrain front seat occu-
pants.
The pretensioners are part of the seat belt retrac-
tor assembly. These seat belts are used the same
way as conventional seat belts.
When a pretensioner activates, smoke is re-
leased and a loud noise may be heard. 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.
After pretensioner activation, load limiters allow
the seat belt to release webbing (if necessary) to
reduce forces against the chest. The supplemental air bag warning light
is
used to indicate malfunctions in the pretensioner
system. For additional information, refer to
Supplemental air bag warning light in this sec-
tion. If the operation of the supplemental air bag
warning light indicates there is a malfunction,
have the system checked by a NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.

Repair and replacement procedure
The front air bags, side air bags, curtain air bags
and pretensioners are designed to inflate on a
one-time-only basis. As a reminder, unless it is
damaged, the supplemental air bag warning light
remains illuminated after inflation has occurred.
Repair and replacement of these supplemental
air bag systems should be done only by a
NISSAN dealer.
When maintenance work is required on the ve-
hicle, the front air bags, side air bags, curtain air
bags, pretensioners and related parts should be
pointed out to the person performing the mainte-
nance. The ignition should always be in the LOCK
position when working under the hood or inside
the vehicle.
WARNING
●Once a front air bag, side air bag, or
curtain air bag has inflated, the air bag
module will not function again and
must be replaced. Additionally, the acti-
vated pretensioners must also be re-
placed. The air bag module and preten-
sioners should be replaced by a
NISSAN dealer. The air bag module and
pretensioners cannot be repaired. ●
The front air bag, side air bag, curtain
air bag systems and the pretensioner
system should be inspected by a
NISSAN dealer if there is any damage to
the front end or side portion of the
vehicle.
● If you need to dispose of a supplemen-
tal air bag or pretensioners or scrap the
vehicle, contact a NISSAN dealer. Incor-
rect disposal procedures could cause
personal injury.
