WARNING
. Never let children ride unrestrained or
extend their hands or face out of the
window. Do not attempt to hold them in
your lap or arms. Some examples of
dangerous riding positions are shown in
the illustrations.
. Children may be severely injured or
killed when the front air bags, side air
bags or curtain air bags inflate if they
are not properly restrained. Pre-teens
and children should be properly re-
strained in the rear seat, if possible.
. Even with the INFINITI Advanced Air Bag
System, never install a rear facing child
restraint in the front seat. An inflating
front air bag could seriously injure or kill
your child. See “Child restraints” earlier
in this section for details.

WARNING
Front seat-mounted side-impact supplemen-
tal air bags and roof-mounted curtain side-
impact supplemental air bags:
.The side air bags and curtain air bags
ordinarily will not inflate in the event of
a frontal impact, rear impact, rollover or
lower severity side collision. Always
wear your seat belts to help reduce the
risk or severity of injury in various kinds
of accidents.
. The seat belts, the side air bags and curtain air bags are most effective when
you are sitting well back and upright in
the seat. The side air bags and curtain
air bags inflate with great force. Do not
allow anyone to place their hand, leg or
face near the side air bags on the side of
the seatback of the front seat or near the
side roof rails. Do not allow anyone
sitting in the front seats or rear outboard
seats to extend their hand out of the
window or lean against the door. Some
examples of dangerous riding positions
are shown in the previous illustrations.
. When sitting in the rear seat, do not
hold onto the seatback of the front seat.
If the side air bags inflates, you may be
seriously injured. Be especially careful
with children, who should always be
properly restrained. Some examples of
dangerous riding positions are shown in
the illustrations.
. Do not use seat covers on the front
seatbacks. They may interfere with side
air bags inflation.

dual stage air bag inflators. The system
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), the
diagnosis sensor unit, seat belt buckle
sensors 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 monitored. Based on in-
formation 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. Addi-
tionally, the front passenger air bag may
be automatically turned OFF under some
conditions, 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 illuminated, 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 per-
formance of the system.
If you have any questions about your air
bag system, contact INFINITI or an INFINITI retailer. If you are considering modification
of your vehicle due to a disability, you may
also contact INFINITI. 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 increasethe 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
collision.
The front air bags operate only when the
ignition switch is in the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warn-
ing light illuminates. The supplemental air
bag warning light will turn off after about
7 seconds if the system is operational.

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 concerning
the use of seats, seat belts and child
restraints can increase the risk or severity of injury in an accident.
Status light:GUID-4D508F5D-FA8E-49D6-A9E2-6F8E76C17033
is located under the climate controls.
After the ignition switch is placed in the ON
position, the front passenger air bag status
light illuminates for about 7 seconds and
then turns off or illuminates depending on
the front passenger occupied status. 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 out-
lined in this section: The
illumi-
nates to indicate that the front
passenger air bag is OFF and will not
inflate in a crash.
. Occupied passenger seat and the pas-
senger meets the conditions outlined in
this section: The light
is OFF to
indicate that the front passenger air
bag is operational.
Front passenger air bag:
GUID-4D508F5D-FA8E-49D6-A9E2-6F8E76C17033

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 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 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. Failing to
properly secure child restrains 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 installation.)
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 occupied. The light will not illuminate
when the front passenger seat is unoccu-
pied.
If an adult occupant is in the seat but the
passenger air bag status light is illumi-
nated (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 inflatein 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 passenger 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
passenger air bag status light will take a
few seconds to register a change in the
passenger seat status. However, if the seat
becomes unoccupied, the air bag status
light will remain off.

passenger air bag system, the supplemen-
tal air bag warning light

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
become dangerous projectiles and cause
injury if the front air bag inflates.
. 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 (pattern sensor).
This can affect the operation of the air
bag system and result in serious perso-
nal injury.
. Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensor. 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 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 air bag system may
result in serious personal injury. Tamper-
ing includes changes to the steering
wheel and the instrument panel assem-
bly by placing material over the steering
wheel pad and above the instrument
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
personal 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 is not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant 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. Installation of electrical equip-
ment should also be done by an INFINITI
retailer. The Supplemental Restraint
System (SRS) wiring harnesses* should
not be modified or disconnected. Un-
authorized electrical test equipment and
probing devices should not be used on

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.
. Right after inflation, several front seat-
mounted side air bags and roof-mounted
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 bags.
This is to prevent damage to or acci-
dental inflation of the side air bag and
curtain air bag systems.
. Do not make unauthorized changes to
your vehicle’s electrical system, suspen-
sion system or side panel. This could
affect proper operation of the side air
bag and curtain air bag systems.
. Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front seat by placing material near the seatback or by
installing additional trim material, such
as seat covers, around the side air bag.
. Work around and on the side air bag and
curtain air bag systems should be done
by an INFINITI retailer. Installation of
electrical equipment should also be
done by an INFINITI retailer. The Supple-
mental Restraint System (SRS) wiring
harnesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the side air bag
or curtain air bag systems.
* 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 side-impact
air bag and curtain side-impact air bag
system and guide the buyer to the appro-
priate sections in this Owner’s Manual.

WARNING
.The pretensioners cannot be reused after
activation. They must be replaced to-
gether with the retractor and buckle as a
unit.
. If the vehicle becomes involved in a
collision but a pretensioner is not
activated, be sure to have the preten-
sioner system checked and, if necessary,
replaced by an INFINITI retailer.
. No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental activa-
tion of the pretensioners. Tampering
with the pretensioner system may result
in serious personal injury.
. Work around and on the pretensioner
system should be done by an INFINITI
retailer. Installation of electrical equip-
ment should also be done by an INFINITI
retailer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system. .
If you need to dispose of the preten-
sioner or scrap the vehicle, contact an
INFINITI retailer. Correct pretensioner
disposal procedures are set forth in the
appropriate INFINITI Service Manual.
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, it helps tighten the seat belt
when the vehicle 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 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 breath-
ing condition should get fresh air promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest. The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. (See “Supplemental
air bag warning light” later in this section
for more details.) If the supplemental air
bag warning light indicates there is a
malfunction, have the system checked by
an INFINITI retailer.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.
