WARNING
.The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity frontal collision. Always wear
your seat belts to help reduce the
risk or severity of injury in various
kinds of accidents.
. The front passenger air bag will not
inflate if the passenger air bag status
light is lit. See “Front passenger air
bag and status light” (P.1-48).
. The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor. The
front air bags inflate with great
force. Even with the INFINITI Ad-
vanced 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
or instrument panel. Always use the
seat belts.

.The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
. The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. These sensors are only
used in this seat. Failure to be
properly seated and wearing the seat
belt can increase the risk or severity
of injury in an accident. See “Front
passenger air bag and status light”
(P.1-48).
. 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.

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
“Child restraints” (P.1-21) for details.

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.

.Do not use seat covers on the front
seatbacks. They may interfere with
side air bag inflation.

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.

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.

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.

Status light:
The front passenger seat is equipped with an
occupant classification sensors (weight sen-
sors) that turn the front passenger air bag on
or off depending on the weight applied to
the front passenger seat. The status of the
front passenger air bag (ON or OFF) is
indicated by the front passenger air bag
status light
which is located on the
instrument panel.
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 remains illuminated de-
pending on the front passenger seat occu-
pied status. The light operates as follows:
