WARNING
• The front air bags ordinarily will not in-
flate 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 in-
jury in various kinds of accidents.
• The front passenger air bag and front
passenger supplemental knee air bag will
not inflate if the passenger air bag status
light is lit. For additional information,
see “Front passenger air bag and status
light” (P. 1-52). •
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 INFINITI Advanced Air Bag System,
if you are unrestrained, leaning forward,
sitting sideways or out of position 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 in-
flates. Always sit back against the seat-
back and as far away as practical from
the steering wheel or instrument 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
INFINITI Advanced Air Bag System
monitors the severity of a collision and
seat belt usage 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 and front passenger
supplemental knee air bag OFF under
some conditions. 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 acci-
dent. For additional information, see
“Front passenger air bag and status
light” (P. 1-52).
• Keep hands on the outside of the steer-
ing wheel. Placing them inside the steer-
ing 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 INFINITI 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
9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
• Make sure that there is nothing pressing
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
under the front passenger seat.
• Make sure that there is no object placed
between the seat cushion and the 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 and front pas-
senger supplemental knee air bag may
deploy in a collision. Also the front pas-
senger air bag status light may not illu-
minate. For additional information, see
“Child restraints” (P. 1-22).
• 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 an INFINITI re-
tailer for this service.
• Until you have confirmed with a retailer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions. •
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 mal-
function has occurred and the front pas-
senger air bag status light may illuminate
and the supplemental air bag warning
light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements un-
der U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual still apply and 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 colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
1-50Safety-Seats, seat belts and supplemental restraint system

The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, door sensors, satellite sensors, the Air
bag Control Unit (ACU), seat belt buckle sen-
sor and occupant classification sensor
(weight sensor). 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 occupants are belted or
unbelted. Additionally, the front passenger
air bag and front passenger supplemental
knee air bag may be automatically turned off
under some conditions, depending on the
weight detected on the passenger seat and
how the seat belt is used. If the front passen-
ger air bag and front passenger supplemental
knee air bag are OFF, the front passenger air
bag status light will be illuminated. For addi-
tional information, see “Front passenger air
bag and status light” (P. 1-52). One front air
bag inflating does not indicate improper per-
formance of the system.If you have any questions about your air bag
system, it is recommended that you visit an
INFINITI retailer to obtain information about
the system. If you are considering modifica-
tion of your vehicle due to a disability, you
may also contact INFINITI. Contact informa-
tion 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, other than the driver and front passen-
ger supplemental knee air bags, do not pro-
vide restraint to the lower body.
Even with INFINITI Advanced Air Bags, seat
belts should be correctly worn and the driver
and passenger seated upright as far as prac-
tical away from the steering wheel or instru-
ment 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 and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF under
some conditions. Read this section care-
fully 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 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 sen-
sor) that turns the front passenger air bag
and front passenger supplemental knee air
bag on or off depending on the weight ap-
plied to the front passenger seat. The status
of the front passenger air bag and front pas-
senger supplemental knee 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 illuminated depending on the front
passenger seat occupied status. The light
operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE 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, see “Normal opera-
tion” (P. 1-54) and “Troubleshooting” (P. 1-55).
LRS0865
1-52Safety-Seats, seat belts and supplemental restraint system

Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically 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 and
front passenger supplemental knee air bag
are OFF, they 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
automatically 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 INFINITI Advanced
Air Bag System is designed to turn the front
passenger air bag and front passenger
supplemental knee 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 and front passenger
supplemental knee air bag to be automati-
cally turned OFF. For small adults it may be
turned OFF, however, if the occupant takes
his/her weight off the seat cushion (for ex-
ample, 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 bags 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.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI 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 and front passenger
supplemental knee 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 front passenger air
bag and front passenger supplemental knee
air bag inflating in a crash instead of being
OFF. For additional information, see “Child
restraints” (P. 1-22).
If the front passenger seat is not occupied,
the front passenger air bag and front passen-
ger supplemental knee air bags are 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 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 occu-
pants are seated and restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag and front passenger supplemental knee
air bags are automatically turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illumi-
nated (indicating that the front passenger air
bag and front passenger supplemental knee
air bags are 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
Safety-Seats, seat belts and supplemental restraint system1-53

NOTE:
This vehicle’s occupant classification sensor
system generally keeps the classification
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 re-
calculate the weight of the occupant under
some conditions (both while driving and
when stopped), so front passenger seat oc-
cupants 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 occupyingthe front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front pas-
senger air bag and front passenger supple-
mental knee air bag are suppressed. However, if the occupant is not a small adult,
then this may be due to the following condi-
tions 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.
• 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 passenger 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 ve-
hicle 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 after 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 an INFINITI retailer for
this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front pas-
senger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• Small adult or child is not sitting upright, leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
• The child restraint is not properly installed, as outlined in the “Child Restraints”
(P. 1-22) section of this manual.
• An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back 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.
