weight NISSAN MAXIMA 2018 Owner´s Manual

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 in-
flate in certain frontal collisions. Vehicle
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 occupation classi-
fication 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 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
occupants are belted or unbelted. Addi-
tionally, the front passenger air bag may be
automatically turned off under some con-
ditions, depending on the weight detected
on the front passenger seat and how theseat belt is used. If the front passenger air
bag is OFF, the front passenger air bag sta-
tus light will be illuminated. For additional
information, refer to “Front passenger air
bag and status light” in this section. One
front air bag inflating does not indicate im-
proper 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 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 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 in-
crease 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 in the ON 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.

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:
CONDITION DESCRIPTIONPASSENGER AIR BAG STA-
TUS 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 de-
scribed above depending on their weight.For additional information, 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-
WRS0475
1-52Safety—Seats, seat belts and supplemental restraint system

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-
ing the air bag to be automatically 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 Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions 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 outlined 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 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
protection by the seat belt and supple-
mental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag OFF for specified child restraints as
required by the regulations. Failing to prop-
erly 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 passenger air bag inflat-
ing in a crash instead of being OFF. For
additional information, refer to “Child re-
straints” 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 baginflation, because of the object’s weight de-
tected by the occupant classification sen-
sor. 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 re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag is automatically turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (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 front passenger air bag status
light may or may not be illuminated, de-
pending on the size of the child and the
type of child restraint being used. If the air
bag status light is not illuminated (indicat-
ing 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 occu-
Safety—Seats, seat belts and supplemental restraint system1-53

pant is positioned properly. If the air bag
status light is still not illuminated, reposi-
tion the occupant or child restraint 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, it is
recommended that you take your vehicle
to a NISSAN dealer. A NISSAN dealer can
check system status 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. This is nor-
mal system operation and does not indi-
cate 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 be illuminated (blinking 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 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.
Front passenger seat belt buckle sta-
tus is monitored by the occupant clas-
sification system, and is used as an in-
put 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 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.
1-54Safety—Seats, seat belts and supplemental restraint system

NOTE:
This vehicle’s occupant classification
sensor system generally keeps the clas-
sification locked during driving, so it is
important that you confirm that the
front passenger is properly classified
prior to driving. However, the occupant
classification sensor may recalculate the
weight of the occupant under some con-
ditions (both while driving and when
stopped), so front passenger seat occu-
pants 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 passenger 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 com-
fortably extended to the floor.
∙ 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 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. 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.
2. 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.
Safety—Seats, seat belts and supplemental restraint system1-55

∙ Modif ying or tampering with the frontpassenger seat may result in serious
personal injury. For example, do not
change the front seats by placing ma-
terial on the seat cushion or by install-
ing additional trim material, such as
seat covers, on the seat that are not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant 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 serious 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 equip-
ment. The Supplemental Restraint
System (SRS) wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the air bag
system.
∙ A cracked windshield should be re- placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
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.

WARNING
∙ Improperly inflated tires can fail suddenly and cause an
accident.
∙ The Gross Vehicle Weight Rating (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label
(if so equipped). Do not load
your vehicle beyond this capac-
ity. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure, or
unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading be-
yond the specified capacity
may also result in failure of
other vehicle components. ∙ Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
∙ Increase the cold tire inflation pressure as indicated in "Check-
ing tire pressure" in this section
when using the tires specified
by NISSAN above 100 mph
(162 km/h) where it is legal to do
so (on a race track for example).
Failure to increase the cold tire
inflation pressure may result in
tire failure, loss of control and
possible injury. Af ter such use,
readjust tire pressure.
∙ For additional information re- garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
