●The driver and front passenger seat belt
buckles are equipped with sensors that de-
tect if the seat belts are fastened. The Ad-
vanced Air Bag System monitors the severity
of a collision and seat belt usage then in-
flates the air bags. 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 (pattern sen-
sor) that turns the front passenger 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 in-
crease the risk or severity of injury in an
accident. See “Front passenger air bag and
status light” later in this section.
● Keep hands on the outside of the steering
wheel. Placing them inside the steering
wheel rim could increase the risk of injury if
the front air bag inflates.

INFINITI ADVANCED AIR BAG SYSTEM
(front seats)
This vehicle is equipped with the INFINITI Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S.
regulations. It is also permitted in Canada.
However, 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 instrument panel 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 an-
other type of collision are similar to those of a
higher severity frontal impact. They may not
inflate in certain frontal collisions. Vehicle dam-
age (or lack of it) is not always an indication of
proper front air bag operation.

The INFINITI Advanced Air Bag System has dual
stage air bag inflators. The system monitors
information from the crash zone sensor, the Air
bag Control Unit (ACU), seat belt buckle
switches and the occupant classification sensor
(pattern 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 moni-
tored. Based on information from the sensors,
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 under some condi-
tions, depending on the information provided
by the occupant classification sensor. If the
front passenger air bag is OFF, the passenger
air bag status light will be illuminated (if the
seat is unoccupied, the light will not be illumi-
nated, but the air bag will be off). (See “Front
passenger air bag and status light” later in this
section for further details.) One front air bag
inflating does not indicate improper perfor-
mance of the system.
If you have any questions about your air bag
system, contact an INFINITI retailer. If you are
considering modification of your vehicle due to
a disability, you may also contact an INFINITI
retailer. Contact 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 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.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the head
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 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
increase the risk of injury if the occupant is too
close to, or is against, the air bag module
during inflation.
The front air bags deflate quickly after a colli-
sion.
The supplemental front air bags operate only
when the ignition switch is in the ON position.
After pushing the ignition switch to the ON posi-
tion, the supplemental air bag warning light illu-
minates. The supplemental air bag warning light
will turn off after about 7 seconds if the system is
operational.

Front passenger air bag and status
light
WARNING
The front passenger air bag is designed to au-
tomatically turn OFF under some conditions.
Read this section carefully to learn how it oper-
ates. Proper use of the seat, seat belt and child
restraints is necessary for most effective pro-
tection. 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 air bag status light
is located above the ashtray. The light operates
as follows:
●
Unoccupied passenger seat: The
is
OFF and the front passenger air bag is OFF
and will not inflate in a crash.
● Passenger seat occupied by a small adult,
child or child restraint as outlined in this
section: The
illuminates to indicate
that the front passenger air bag is OFF and
will not inflate in a crash.
● Occupied passenger seat and the passenger
meets the conditions outlined in this sec-
tion: The light
is OFF to indicate that
the front passenger air bag is operational.
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 as permitted by 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.
The occupant classification sensor (pattern sen-
sor) is in the front passenger seat cushion and
is designed to detect an occupant and objects
on the seat. 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 sen-
sor 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 occupant does not sit in the seat
properly (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 supplemental air bag.
INFINITI recommends that pre-teens and chil-
dren 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 re-
straints. Failing to properly secure child re-
straints and to use the ALR mode (child restraint
mode) may allow the restraint to tip or move in
an accident or sudden stop. This can also result
in the passenger air bag inflating in a crash
instead of being OFF. (See “CHILD RESTRAINTS”
earlier in this section for proper use and instal-
lation.)
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 being 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
automatically turned OFF with the seat occu-
pied. The light will not illuminate when the front
passenger seat is unoccupied.If an adult occupant is in the seat but the
passenger 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.
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 passenger 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 passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the 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, the system may be
sensing an unoccupied seat (in which case the
air bag is OFF). Your INFINITI retailer can check
that the system is OFF by using a special tool.
However, until you have confirmed with your
retailer that your air bag is working properly,
reposition the occupant or child restraint in a
rear seat.The INFINITI advanced air bag system and pas-
senger air bag status light will take a few
seconds to register a change in the passenger
seat status. However, if the seat becomes un-
occupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag warn-
ing light
, located in the meter and
gauges area will blink. Have the system
checked by an INFINITI retailer.
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 occu-
pant and the steering wheel or instrument
panel. Such objects may become dangerous
projectiles and cause injury if the front air
bags inflate.

01/11/10—pattie


●Do not place objects with sharp edges on the
seat. Also, do not place heavy objects on the
seat that will leave permanent impressions
in the seat. Such objects can damage the
seat or occupant classification sensor (pat-
tern sensor). This can affect the operation of
the air bag system and result in serious per-
sonal injury.
● Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sor. This can also affect the operation of the
air bag system and result in serious personal
injury.
● Immediately after inflation, several front 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 air bag sys-
tem. 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, suspension sys-
tem or front end structure. This could affect
proper operation of the front air bag system. ●
Tampering with the air bag system may re-
sult 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 instrument panel or by installing
additional trim material around the air bag
system.
● Modifying or tampering with the front pas-
senger seat may result in serious personal
injury. For example, do not change the front
seats by placing material on the seat cush-
ion or by installing additional trim material,
such as seat covers, on the seat that is not
specifically 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.
● 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. ●
Work on and around the front air bag system
should be done by an INFINITI retailer. Instal-
lation of electrical equipment should also be
done by an INFINITI retailer. The Supplemen-
tal Restraint System (SRS) wiring har-
nesses* 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 replaced im-
mediately by a qualified repair 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 identification.
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.

becomes involved in certain types of collisions,
helping to restrain front seat occupants.
The pretensioner is encased with the seat belt
retractor. These seat belts are used the same
way as conventional seat belts.
When a pretensioner seat belt activates, smoke
is released and a loud noise may be heard. The
smoke is not harmful, and it 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 al-
low the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
The supplemental air bag warning light
is used to indicate malfunctions in the preten-
sioner system. See “SUPPLEMENTAL AIR BAG
WARNING LIGHT” later in this section. If the
supplemental air bag warning light illuminates,
have the system checked by a NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the seat belt pretension-
ers and guide the buyer to the appropriate
sections in this Owner’s Manual.
