Infiniti Advanced Air Bag System
(front seats)
WARNING
To ensure proper operation of the passen-
ger's INFINITI Advanced Air Bag System,
please observe the following items:
•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. For additional information
about installing and using child re-
straints, refer to "Child restraints".
•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
described in this section. It is recom-
mended that you visit an INFINITI re-
tailer to check the occupant classifica-
tion system.
•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.
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 warn-
ings 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 supple-
mental 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 frontalcollisions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
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 (pressure 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 may be automatically turned off un-
der some conditions, depending on the infor-
mation provided by the Occupation Classifi-
cation System Sensor. If the front passenger
air bag is OFF, the
indicator light will be illuminated.
For additional information, refer to "Front
passenger air bag and status light". One front
air bag inflating does not indicate improper
performance of the system.
If a crash occurs in which the vehicle's air
bags deploy, by design the vehicle may not
restart. If this occurs, it is recommended that
you visit an INFINITI retailer for repair.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 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
1-44Safety — seats, seat belts and supplemental restraint system
Page 63 of 436
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 a few seconds af-
ter the engine starts if the system is opera-
tional.
Front passenger air bag and status
light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some condi-
tions. 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 instructions in this manual con-
cerning the use of seats, seat belts and
child restraints can increase the risk or se-
verity of injury in an accident.

cator light
2
dicator light
Status light
The front passenger seat is equipped with an
occupant classification sensor (pressure sen-
sor) that turns the front passenger air bag on
or off depending on the weight applied to the
front passenger seat. The indicator lights in-
form you whether the front passenger front
air bag is disabled or enabled.
Place the ignition in the ON position. The
system carries out a self-diagnosis.The
light up simultaneously for approximately six
seconds.
The indicator lights display the status of the
front passenger front air bag:
•
front passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front passenger front
air bag is deployed.
•
the front passenger front air bag is dis-
abled. It will then not be deployed in the
event of an accident.
If the status of the front passenger front air
bag changes while the vehicle is in motion, an
air bag display message appears in the ve-
hicle information display. When the front
passenger seat is occupied, always pay at-
tention to the
and
lights. Be aware of the status of the front
passenger front air bag both before and dur-
ing the journey.
If neither the
or the
lights light up, or if either indicator light only
lights up intermittently during the journey, the
front passenger seat may not be used for a

child restraint. Use another seating position
for the child restraint. INFINITI recommends
that all child restraints be installed in the rear
seat. Preteen children should be seated in
the rear seat. For further information see
"Troubleshooting" later 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 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 automatically turned OFF
under some conditions. Certain sensors are
used to meet the requirements.
The occupant classification sensor in this ve-
hicle is a pressure sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child up to the
approximate size and weight of a one year
old is properly restrained is in the front pas-
senger seat, the INFINITI Advanced Air Bag
System is designed to turn the front passen-
ger air bag OFF. For a properly restrained
child who is larger than the approximate sizeand weight of a one year old, the front pas-
senger air bag may or may not be automati-
cally turned OFF, depending on the size of
the child and the type of child restraint being
used. After installing the child restraint and
positioning the child, place the ignition switch
in the ON position: if the
air bag is OFF. If the
will inflate in a crash. 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 oth-
erwise 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 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 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 passenger air bag
inflating in a crash instead of being OFF. For
additional information about proper use and
installation, refer to "Child restraints".
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 bag
inflation, because of the object's weight de-
tected 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, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
If the automatic front passenger air bag de-
activation system detects that:
•The front passenger seat is unoccupied,
the
tor light lights up after the system self-test
and remains lit. This indicates that the
front passenger front air bag is disabled.

•The front passenger seat is occupied by a
properly restrained child up to the approxi-
mate size and weight of a one year old, the
light lights up after the system self-test
and remains lit. This indicates that the
front passenger front air bag is disabled.
If neither the
indicator lights light up, or if either indica-
tor light only lights up intermittently during
the journey, the front passenger seat
may not be used for a child restraint. Use
another seating position for the child re-
straint. For further information see
"Troubleshooting" later in this section.
•The front passenger seat is occupied by a
properly restrained child who is larger than
the approximate size and weight of a one
year old, either the
indicator light lights up and remains lit af-
ter the system self-test depending on the
result of the classification. The result of
the classification is dependent on, among
other factors, the child restraint system
and the child's build.
Move the front passenger seat as far back
as possible. See "Child restraints" earlier in
this section.
•The front passenger seat is occupied by a
person with a smaller build (e.g. a teenager
or small adult), either the
lit after the system self-test depending on
the result of the classification.
– If the
cator light lights up, move the front
passenger seat as far back as possible.
Alternatively, a person with a small
build can sit on a rear seat.
– If the
indicator light is lit, a person with a
smaller build should not use the front
passenger seat.
•The front passenger seat is occupied by an
adult or a person with a build correspond-
ing to that of an adult, the
the system self-test and remains lit. This
indicates that the front passenger front air
bag is enabled.If the automatic front passenger front air bag
deactivation system is malfunctioning, the

combination meter and the
taneously. The front passenger front air bag
is disabled in this case and does not deploy
during an accident. Have the system checked
as soon as possible by qualified technicians. It
is recommended that you visit an INFINITI
retailer for this service.

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.
•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 in-
strument panel or by installing addi-
tional 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
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, 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 (pressure 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 seri-
ous 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
installation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modi-
fied 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 facil-
ity. A cracked windshield could affect
the function of the supplemental air bag
system.

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 curtain
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 de-
signed to inflate in higher severity side colli-
sions, 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 ofrollover collisions or near rollovers. As a re-
sult, certain vehicle movements (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 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 in all rows. 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 front passenger seated upright
as far as practical away from the side air bag.
Rear seat passengers should be seated as faraway 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 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 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 oper-
ate 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 a few seconds after the engine starts 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 sys-
tems. This is to prevent damage to or
accidental inflation of the side air bag

Driver and passenger supplemental
knee air bags
The driver's knee air bag deploys under the
steering column, while the passenger's knee
air bag deploys under the glove box. All of the
information, cautions and warnings in this
manual apply and must be followed. The driv-
er's and passenger's knee air bags are trig-
gered together with the front air bag. The
knee 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 fron-
tal impact. They may not inflate in certain
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation.
When a knee air bag inflates, 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 promptlyThe knee air bags help to cushion the impact
force on the knees of the driver and front
passenger. They can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee air
bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of this,
the force of the knee air bag inflating can
increase the risk of injury if the occupant is
too close to, or is against, this air bag module
during inflation. The knee air bag will deflate
quickly after the collision is over OR the knee
air bag will remain inflated for a short time.
The knee air bags operate only when the ig-
nition 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 a few seconds af-
ter the engine starts if the system is opera-
tional.
WARNING
•Do not place any objects between the
knee bolster and the driver’s seat. Such
objects may become dangerous projec-
tiles and cause injury if a knee air bag
inflates.

vent damage to or accidental activation
of the pretensioner(s). Tampering with
the pretensioner system may result in
serious personal injury.
•It is recommended that you visit an
INFINITI retailer for work on and around
the pretensioner system. It is also rec-
ommended that you visit an INFINITI
retailer for installation of electrical
equipment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
•If you need to dispose of the pretension-
er(s) or scrap the vehicle, it is recom-
mended that you visit an INFINITI re-
tailer for this service. 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 pretensioner(s) help tighten the
seat belt when the vehicle becomes involved
in certain types of collisions, helping to re-
strain front seat and rear outboard occu-
pants. The pretensioner(s) are encased within
the seat belt retractor and to the seat belt
anchor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts. When pretension-
er(s) activate, smoke is released and a loud
noise may be heard. This smoke is not harm-
ful and does not indicate a fire. Care should
be taken not to inhale it, as it may cause
