WARNING
.The supplemental front air bags or-
dinarily will not inflate in the event of
a side impact, rear impact, rollover, or
lower severity frontal collision. Al-
ways wear your seat belts to help
reduce the risk or severity of injury in
various kinds of accidents.
. The front passenger air bag and front
passenger knee air bag will not
inflate if the front passenger air bag
status light is lit or if the front
passenger seat is unoccupied. See
“Front passenger air bag and status
light” (P.1-59).
. 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 inflates. Always sit back
against the seatback and as far-away
as practical from the steering wheel

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 posi-
tions 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
restrained 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

WARNING
Front seat-mounted side-impact supple-
mental air bags and roof-mounted cur-
tain side-impact and rollover
supplemental air bags:
.The side-impact supplemental air
bags ordinarily will not inflate in the
event of a front impact, rear impact,
rollover, or lower severity side colli-
sion. Always wear your seat belts to
help reduce the risk or severity of
injury in various kinds of accidents.
. The curtain side-impact and rollover
supplemental air bags ordinarily will not inflate in the event of a front
impact, rear impact, 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 bag inflates, you
may be seriously injured. Be espe-
cially careful with children, who
should always be properly restrained.
Some examples of dangerous riding
positions are shown in the illustra-
tions.

WARNING
To ensure proper operation of the pas-
senger’s 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 lbs. (4 kg) on the seatback,
head restraint or in the seatback
pocket.
. Do not store cargo behind the seat
that can press into the seatback.
. Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
Safety — seats, seat belts and supplemental restraint system1-57

1-58Safety — seats, seat belts and supplemental restraint system
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
. If a forward facing child restraint is
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts
the instrument panel. If the child
restraint does contact the instrument
panel, the system may determine the
seat is occupied and the passenger air
bag and front passenger knee air bag
may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. See “Child re-
straints” (P.1-30) for information
about installing and using child re-
straints.
. 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 in
accordance with the above descrip-
tion, it is recommended you visit an
INFINITI retailer to check the pas-
senger seat advanced air bag system. .
Until you have confirmed with your
retailer that your passenger seat
advanced air bag is working properly,
position the occupants in the rear
seating 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
under U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual apply and must be
followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The 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 another type of collision are
similar to those of a higher severity frontal
impact. They may not inflate in certain
frontal collisions. Vehicle damage (or lack
of it) is not always an indication of proper
front air bag operation.
The INFINITI Advanced Air Bag System
monitors information from the Air bag
Control Unit (ACU), seat belt buckle sensors
and the occupant classification sensors (weight sensors). Inflator operation is based
on the severity of a collision and seat belt
usage for the driver. For the front passenger,
the occupant classification sensors are also
monitored. 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 and front passenger knee air bag may
be automatically turned OFF under some
conditions, depending on the information
provided by the occupant classification
sensors. If the front passenger air bag and
front passenger knee air bag are OFF, the
front 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” (P.1-59) for further details.)
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 you visit an
INFINITI retailer. If you are considering
modification of your vehicle due to a dis-
ability, 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, other than the driver’s and
front passenger’s 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
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
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 warning
light illuminates. The supplemental air bag
warning light will turn off after about 7seconds if the system is operational.

Front passenger air bag status light
Front passenger air bag and status
light
WARNING
The front passenger air bag and front
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 instructions in this
manual concerning the use of seats, seat
Safety — seats, seat belts and supplemental restraint system1-59

possible, the occupant classification sensors
are designed to operate as described above
to turn the front passenger air bag and front
passenger knee air bag OFF for specified
child restraints. Failing to properly secure
child restrains and to use the ALR mode may
allow the restraint to tip or move in an
accident or sudden stop. This can also result
in the passenger air bag and front passenger
knee air bag inflating in a crash instead of
being OFF. (See “Child restraints” (P.1-30)
for proper use and installation.)
If the front passenger seat is not occupied,
the passenger air bag and front passenger
knee air bag are 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 sensors. 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 front passenger air bag status
light, you can monitor when the front
passenger air bag and front passenger knee
air bag are automatically turned OFF with
the seat occupied. The light will not illumi-
nate when the front passenger seat is
unoccupied.If an adult occupant is in the seat but the
front passenger air bag status light is
illuminated (indicating that the air bag and
front passenger knee air bag are 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 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 front passenger
air bag status light is not illuminated (in-
dicating 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
front passenger air bag status light is still not
illuminated, reposition the occupant or child
restraint in a rear seat.
If the front 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 sys-
tem 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
front 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 front passenger air
bag status light will remain off.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area will blink. Have the system
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation:
In order for the occupant classification
sensor system to classify the front passen-
ger based on weight, please follow the
precautions and steps outlined below:
Precautions:
. Make sure that there are no objects
weighing over 9.1 lbs (4 kg) hanging on
the seat or placed in the seatback pocket.
. Make sure that a child restraint or other
object is not pressing against the rear of
the seatback.
. Make sure that a rear passenger is not
pushing or pulling on the back of the
front passenger seat.
. Make sure that the front passenger seat
or seatback is not forced back against an

Safety — seats, seat belts and supplemental restraint system1-61

.An object placed under the front passen-
ger 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 vehicle 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 it is recommended that
the vehicle be checked by an INFINITI
retailer as soon as possible.
3. If the light is OFF with a small adult, child or child restraint occupying the
front passenger seat.
This may be due to the following
conditions that may be interfering with
the weight sensors:
. Small adult or child is not sitting upright,
leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor. .
The child restraint is not properly in-
stalled, as outlined. (See “Child re-
straints” (P.1-30).)
. An object weighing over 9.1 lbs (4 kg)
hanging on the seat or placed in the
seatback 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 passen-
ger seat.
. An object placed between the seat
cushion and center console.
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 vehicle 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 OFF after this, the small
adult, child or child restraint should be
repositioned in the rear seat and it is
recommended that the vehicle be checked by an INFINITI retailer as soon as possible.
Other supplemental front-impact
air bag precautions
WARNING
.
Do not place any objects on the
steering wheel pad or on the instru-
ment 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 in-
jury if the front air bags inflate.
. 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 sensors
(weight sensors). This can affect the
operation of the air bag system and
result in serious personal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensors. This can also
affect the operation of the air bag
system and result in serious personal
injury.

DRIVER AND FRONT PASSEN-
GER SUPPLEMENTAL KNEE AIR
BAG
The knee air bag is located in the knee
bolster, on the driver’s and front passenger’s
sides.All of the information, cautions and
warnings in this manual apply and must be
followed. The knee air bag is designed to
inflate in higher severity frontal collisions,
although it may inflate if the forces in
another type of collision are similar to those
of a higher severity frontal impact. It may
not inflate in certain collisions.
WAB0181X
Front passenger’s side
Vehicle damage (or lack of it) is not always
an indication of proper knee air bag opera-
tion.
When the 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 bag helps to cushion the impact
force on the knees of the driver and front
passenger. It can help reduce serious injuries.
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 bag operates 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
seconds if the system is operational.
WARNING
.
Do not place any objects between the
knee bolster and the driver’s or front
passenger’s seat. Such objects may
become dangerous projectiles and
cause injury if a knee air bag inflates.
. Right after inflation, the knee 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
Safety — seats, seat belts and supplemental restraint system1-65

1-66Safety — seats, seat belts and supplemental restraint system
the knee air bag system. This is to
prevent damage to or accidental
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 or front passenger knee
bolster or install additional trim ma-
terial around the knee air bag.
. It is recommended that you visit an
INFINITI retailer for work on and
around the knee air bag. It is also
recommended that you visit an
INFINITI retailer for installation of
electrical equipment. The SRS wiring
harnesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the knee air
bag system. *The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the knee air bag
system and guide the buyer to the appro-
priate sections in this manual.
