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 vehicle
information display (seeSupplemental Re-
straint System (SRS) air bag warning light
earlier in this section). When the front passen-
ger seat is occupied, always pay attention to
the and AIRBAG OFF> indicator lamps. Be aware of the
status of the front-passenger front air bag both
before and during the journey.
If the indicator lamp
remains off and/or the ON> indicator lamp lights up, do not install a
rearward-facing child restraint system on the
front-passenger seat. For further information
seeTroubleshootinglater 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 seatoccupants, 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 pressure 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
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. INFINITI recommends that pre-
teens and children be properly restrained in a
rear seat. INFINITI also recommends that appro-
priate child restraints and booster seats beproperly 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 toChild restraintsin the1. Safety —
seats, seat belts and supplemental restraint
systemsection.
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, contrary
to the instructions in this manual. Always be
sure that you and all vehicle occupants are
seated and restrained properly.

If the automatic front-passenger air bag deacti-
vation system detects that:
•The front-passenger seat is unoccupied, the
indicator lamp
lights up after the system self-test and re-
mains lit. This indicates that the front pas-
senger front air bag is disabled.
•The front-passenger seat is occupied by a
child in a rearward-facing child restraint sys-
tem, the indicator
lamp lights up after the system self test and
remains lit. This indicates that the front-
passenger front air bag is disabled.
If the indicator
lamp remains off and/or the BAG ON> indicator lamp lights up, do not
install a rearward facing child restraint sys-
tem on the front passenger seat. For further
information seeTroubleshootinglater in

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.
•Immediately after inflation, several front air
bag system components will be hot. Do not
touch them; you may severely burn your-
self.
•No unauthorized changes should be made
to any components or wiring of the supple-
mental air bag system. This is to prevent
accidental inflation of the supplemental air

•Removing or modifying the front passenger
seat may affect the function of the air bag
system and result in serious personal in-
jury.
•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 are 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 ob-
jects may interfere with the proper opera-
tion 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 sys-
tem may result in serious personal injury.

Front seat-mounted side-impact
supplemental air bag and window
bag/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 designed to
inflate in higher severity side collisions, al-
though 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. Cur-
tain air bags are also designed to inflate incertain types of rollover collisions or near roll-
overs. As a result, 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 occu-
pants in the front and rear outboard seating
positions in all rows. They can help save lives
and reduce serious injuries. However, an inflat-
ing 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. Rearseat passengers should be seated as far away
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 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 after the
engine starts if the system is operational.
WARNING
•Do not place any objects near the seatback
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.
NPA849Z
1-52Safety — seats, seat belts and supplemental restraint system

•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 systems. This is to
prevent damage to or accidental inflation of
the side air bag and curtain air bag systems.
•Do not make unauthorized changes to your
vehicle’s electrical system, suspension sys-
tem or side panel. This could affect proper
operation of the curtain air bag systems.
•Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front seats by
placing material near the seatbacks or by
installing additional trim material, such as
seat covers, around the side air bag.
•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 electri-
cal equipment. The SRS wiring harnesses*
should not be modified or disconnected. Un-
authorized electrical test equipment and
probing devices should not be used on the
side air bag or curtain air bag systems.
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 sever-
ity 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 colli-
sions.
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 promptly
The 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 maycause 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 infla-
tion. 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 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 between the knee
bolster and the driver’s seat. Such objects
may become dangerous projectiles and
cause injury if a knee air bag inflates.
•Right after inflation, the knee air bag sys-
tem components will be hot. Do not touch
them; you may severely burn yourself.
Safety — seats, seat belts and supplemental restraint system1-53

•No unauthorized changes should be made to
any components or wiring of the knee air bag
system. This is to prevent damage to or acci-
dental inflation of the knee air bag system.
•Do not make unauthorized changes to your
vehicle’s electrical system or suspension
system. This could affect proper operation
of the knee air bag system.
•Tampering with the knee air bag system
may result in serious personal injury. For
example, do not change the driver knee bol-
ster or install additional trim material
around the knee air bag.
•It is recommended that you visit an INFINITI

Seat belt with pretensioner(s)
WARNING
•The pretensioner(s) cannot be reused after
activation. They must be replaced together
with the retractor and buckle as a unit.
•If the vehicle becomes involved in a colli-
sion but pretensioner(s) are not activated,
be sure to have the pretensioner system
checked and, if necessary, replaced. It is
recommended that you visit an INFINITI re-
tailer for this service.
•No unauthorized changes should be made
to any components or wiring of the preten-
sioner system. This is to prevent damage to
or accidental activation of the pretension-
er(s). Tampering with the pretensioner sys-
tem may result in serious personal injury.
•It is recommended that you visit an INFINITI
retailer for work on and around the preten-
sioner system. It is also recommended that
you visit an INFINITI retailer for installation
of electrical equipment. Unauthorized elec-
trical test equipment and probing devices
should not be used on the pretensioner sys-
tem.
•If you need to dispose of the pretension-
er(s) or scrap the vehicle, it is recommended
that you visit an INFINITI retailer 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 restrain front seat
occupants. 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 pretensioner(s)
activate, smoke is released and a loud noise
may be heard. 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. After
the pretensioner(s)’s activation, load limiters
allow the seat belt to release webbing (if nec-
essary) to reduce forces against the chest. The
supplemental air bag warning light is used to
