WARNING
Front seat-mounted side-impact supple-
mental air bags and roof-mounted cur-
tain side-impact and rollover
supplemental air bags:
.The side 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 curtain 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, side air bags and
curtain air bags are most effective
when you are sitting well back and
upright in the seat. The side air bag
and curtain air bag inflate with great
force. Do not allow anyone to place
their hand, leg or face near the side
air bag 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 supplemental side air bag
inflates, you may be seriously injured.
Be especially careful with children,
who should always be properly re-
strained. Some examples of danger-
ous riding positions are shown in the
illustrations.

INFINITI ADVANCED AIR BAG
SYSTEM (front seats)
WARNING
To ensure proper operation of the pas-
senger’s Advanced Air Bag System, ob-
serve 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 9.1 lbs. (4 kg) on the seatback,
head restraint or in the seatback
pocket.
. Make sure that there is nothing
pressing against the rear of the seat-
back, such as a child restraint in-
stalled in the rear seat or an object
stored on the floor.
. Make sure that there is no object
placed under the front passenger
seat.

.Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.
. Be sure that the front passenger seat
does not contact the rear seat, in-
strument panel, etc., or the head
restraint does not contact the roof.
. 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
recommended you visit an INFINITI
retailer to check the passenger seat
Advanced Air Bag System.
. Until you have confirmed with a
retailer that your passenger seat
Advanced Air Bag System is working
properly, position the occupants in
the rear seating positions.
. Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
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.
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 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 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 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 sensors (weight sensors). In-
flator 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
may be automatically turned OFF under
some conditions, depending on the informa-
tion provided by the occupant classification
sensors. If the front passenger air bag is
OFF, the front passenger air bag status light
will be illuminated. (See “Front passenger air
bag and status light” (P.1-48) for further
details.) One front air bag inflating does not
indicate improper performance of the sys-
tem.
If you have any questions about your air bag
system, it is recommended you visit an
INFINITI retailer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, 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.
Safety — Seats, seat belts and supplemental restraint system1-47

1-48Safety — Seats, seat belts and supplemental restraint system
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
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 7
seconds if the system is operational.
JVR0192X
Front passenger air bag and status
light
WARNING
The front passenger air bag is 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
belts and child restraints can increase
the risk or severity of injury in anaccident.

1-52Safety — Seats, seat belts and supplemental restraint system
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, it is re-
commended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check the system status by using a special
tool. However, until you have confirmed
with your retailer that your air bag is work-
ing 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. This is normal system
operation and does not indicate a malfunc-
tion.
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 of the instrument panel, will be illuminated (blinking or steadily lit). 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
object on the seat or floor behind it.
. Make sure that there is no object placed
under the front passenger seat.
. Make sure that the front passenger seat
head restraint does not contact the roof
when adjusting the front passenger seat.
Steps
1. Adjust the seat as outlined in “Seats” (P.1-2). Sit upright, leaning against the
seatback, and centered on the seat cushion with your feet comfortably ex-
tended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in “Seat belts” (P.1-12). Front passenger seat belt
buckle status is monitored by the occu-
pant classification sensor system, and is
used as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fastens his/her seat
belt.
4. Remain in this position for 30 seconds allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification sensor
system generally keeps the classification
locked during driving, so it is important that
you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor may
recalculate the weight of the occupant
under some conditions (both while driving
and when stopped), so the front passenger
seat occupant should continue to remain
seated as outlined above.

1-54Safety — Seats, seat belts and supplemental restraint system
ger seat, the vehicle should be checked
as soon as possible. It is recommended
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 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.
. 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 supple-
mental air bag or damage to the
supplemental air bag system.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
. Tampering with the 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 instrument panel or by
installing additional trim material
around the air bag system.
. Removing or modifying the front
passenger seat may affect the func-
tion 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 mate-
rial, 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 classifica-
tion sensors.
. 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.
. It is recommended you visit an
INFINITI retailer for work on and
around the front air bag. It is also
recommended you visit an INFINITI
retailer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag

system.
. A cracked windshield should be re-
placed immediately 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 identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appro-
priate sections in this Owner’s Manual.

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 designed to inflate in higher
severity side collisions, 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 of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental side air
bag and curtain side-impact air bag opera-
tion.
When side air bags and curtain air bags
inflate, 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.
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. However, an inflating side air bags
and curtain air bags may cause abrasions or
Safety — Seats, seat belts and supplemental restraint system1-55

1-56Safety — Seats, seat belts and supplemental restraint system
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 passenger seated upright as
far as practical away from the side air bag.
Rear seat 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 in
the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The air bag warning light
will turn off after about 7 seconds if the
systems are 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 pro-
jectiles and cause injury if side air bag
inflates.
. Right after inflation, several side air
bags and curtain 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
side air bag and curtain air bags. 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 system or side panel. This
could affect proper operation of the
side air bag and curtain air bag
systems.
. Tampering with the air bag system
may result in serious personal injury.
For example, do not change the front seats by placing material near the
seatback or by installing additional
trim material, such as seat covers,
around the side air bags.
. It is recommended you visit an
INFINITI retailer for work on and
around the side air bag and curtain
air bag. It is also recommended you
visit an INFINITI retailer for installa-
tion of electrical equipment. 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 the side-impact air bag
system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner’s Manual.

SEAT BELTS WITH PRETEN-
SIONERS (front seats)
WARNING
.The pretensioners cannot be reused
after activation. They must be re-
placed together 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 pre-
tensioner system checked and, if
necessary, replaced. It is recom-
mended you visit an INFINITI retailer
for this service.
. No unauthorized changes should be
made to any components or wiring of
the pretensioners. This is to prevent
damage to or accidental activation of
the pretensioner system. Tampering
with the pretensioner system may
result in serious personal injury.
. It is recommended you visit an
INFINITI retailer for work on and
around the pretensioner system. It is
also recommended 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 preten-
sioner or scrap the vehicle, it is
recommended you visit an INFINITI
retailer for this service. Correct pre-
tensioner disposal procedures are set
forth in the appropriate INFINITI
Service Manual. Incorrect disposal
procedures could cause personal in-
jury.
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 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
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” (P.1-58) for more
details.) If the operation of the supplemental
air bag warning light indicates there is a
malfunction, have the system checked. It is
recommended you visit an INFINITI retailer
for this service.
When selling your vehicle, we request that
you inform the buyer about the seat belt
pretensioners and guide the buyer to the
appropriate sections in this Owner’s Manual.
