7. If the booster seat is installed in the frontpassenger seat, push the ignition switch
to the ON position. The front passenger
air bag status light
may or may not
illuminate depending on the size of the
child and the type of booster seat used.
See “Front passenger air bag and status
light” (P.1-50).
PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems:
. Driver and passenger front-impact sup-
plemental air bags (INFINITI Advanced
Air Bag System)
. Front seat-mounted side-impact supple-
mental air bag
. Roof-mounted curtain side-impact and
rollover supplemental air bag
. Seat belt with pretensioner
Supplemental front-impact air bag system:
The INFINITI Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact supple-
mental air bag system: This system can help
cushion the impact force to the chest and
pelvis area of the driver and front passenger
in certain side impact collisions. The side air
bag is designed to inflate on the side where
the vehicle is impacted.
Roof-mounted curtain side-impact and roll-
over supplemental air bag system: This
system can help cushion the impact force
to the head of occupants in front and rear
outboard seating positions in certain side impact or rollover collisions. In a side impact,
the curtain air bags are designed to inflate
on the side where the vehicle is impacted. In
a rollover, the curtain air bags on both sides
are designed to inflate and remain inflated
for a short time.
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.
These supplemental restraint systems are
designed to
supplement the crash protection
provided by the driver and passenger seat
belts and are not a substitute for them. Seat
belts should always be correctly worn and
the occupant seated a suitable distance
away from the steering wheel, instrument
panel and door finishers. (See “Seat belts”
(P.1-12) for instructions and precautions on
seat belt usage.)
The supplemental 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 systems are operational.

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.1-50) 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.
