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 passen-
ger knee air bag will not inflate if the
passenger air bag status light is lit. For
additional information, see “Front pas-
senger air bag and status light” (P. 1-51). •
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 passenger 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 accident. For additional in-
formation, see “Front passenger air bag
and status light” (P. 1-51).
• 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 may deploy in
a collision. Also the front passenger air
bag status light may not illuminate. For
additional information, see “Child re-
straints” (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.
Safety-Seats, seat belts and supplemental restraint system1-49

The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensor and occupant classifica-
tion sensor (weight sensor). Inflator opera-
tion 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 passenger knee air bag may be
automatically turned off under some condi-
tions, depending on the weight detected on
the passenger seat and how the seat belt is
used. If the front passenger air bag and pas-
senger knee air bag is OFF, the front passen-
ger air bag status light will be illuminated. For
additional information, see “Front passenger
air bag and status light” (P. 1-51). 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 an
INFINITI retailer to obtain information about
the system. If you are considering modifica-
tion of your vehicle due to a disability, youmay 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 passenger
knee air bags, do not provide 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 passenger
knee air bag are 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
protection. Failure to follow all instruc-
tions 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 passenger knee air bag on or off depend-
ing on the weight applied to the front passen-
ger seat. The status of the front passenger air
bag and passenger 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 re-
mains illuminated depending on the front
passenger seat occupied status. The light op-
erates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND PASSENGER 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 op-
eration” (P. 1-53) and “Troubleshooting”
(P. 1-54).

Front passenger air bag
The front passenger air bag and passenger
knee air bag is designed to automatically turn
OFF when the vehicle is operated under
some conditions as described below in accor-
dance with U.S. regulations. If the front pas-
senger air bag and passenger knee 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 re-
duce the risk of injury or death from an inflat-
ing air bag to certain front passenger seat
occupants, such as children, by requiring the
air bag to be automatically turned OFF. Cer-
tain 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 OFF in accordance with
the regulations. Also, if a child restraint of the
type specified in the regulations 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 occupant 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 posi-
tion), 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
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 passenger knee
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 front passenger air bag and pas-
senger knee air bag inflating in a crash in-
stead of being OFF. For additional informa-
tion, see “Child restraints” (P. 1-22).If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee 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 occu-
pant 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 in-
structions in this manual. Always be sure that
you and all vehicle occupants are seated and
restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag and passenger knee air bag is automati-
cally 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 passenger knee 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, 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 front
1-52Safety-Seats, seat belts and supplemental restraint system

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 prop-
erly classified prior to driving. However, the
occupant classification sensor may recalculate
the weight of the occupant under some condi-
tions (both while driving and when stopped),
so front passenger seat occupants should con-
tinue 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 passenger 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 4 kg (9.1 lbs.) 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.
• An object placed under the front passenger seat.
• An object placed between the seat cushion and center console.

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 in-
jury 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, suspen-
sion 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 instru-
ment 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 per-
sonal injury. For example, do not change
the front seats by placing material on the
seat cushion or by installing additional
trim material, such as seat covers, on the
seat that are not specifically designed to
assure proper air bag operation. Addi-
tionally, 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 serious
personal injury.
• It is recommended that you visit an
INFINITI retailer for work on and around
the front air bag. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modified
or disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag system.
• A cracked windshield should be replaced
immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.

low 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 appropri-
ate sections in this Owner's Manual.
Front and rear outboard
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 and rear outboard
seats. The curtain air bags are located in the
side roof rails. All of the information, cau-
tions 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 certain side collisions.
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, fol-
lowed by the 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
and pelvic area of the front and rear outboard
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
