PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
• Driver and front passenger supplementalfront-impact air bag (INFINITI Advanced
Air Bag System)
• Front seat-mounted side-impact supple- mental air bag
• Rear outboard seat-mounted side-impact supplemental air bag system
• Roof-mounted curtain side-impact and rollover supplemental air bag
• Driver and passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front and rear outboard seats)
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 area of the driver and front
passenger in certain side-impact collisions.
The side air bags are designed to inflate on
the side where the vehicle is impacted. Rear outboard seat-mounted side-impact
supplemental air bag system
This system can help cushion the impact
force to the chest area of the rear seat pas-
sengers in certain side-impact collisions. The
side air bags are 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 im-
pacted. In a rollover, the curtain air bags are
designed to inflate and remain inflated for a
short time.
The SRS is designed to
supplementthe crash
protection provided by the driver and front
passenger seat belts and is not a substitute
for them. Seat belts should always be cor-
rectly worn and the occupant seated a suit-
able distance away from the steering wheel,
instrument panel and door finishers. For ad-
ditional information, see “Seat belts” (P. 1-11). Driver and passenger supplemental knee air
bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.
The SRS is designed to
supplementthe crash
protection provided by the driver and front
passenger seat belts and is not a substitute
for them. Seat belts should always be cor-
rectly worn and the occupant seated a suit-
able distance away from the steering wheel,
instrument panel and door finishers. For ad-
ditional information, see “Seat belts” (P. 1-11).
The supplemental air bags operate 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 sec-
onds if the system is operational.
SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
Safety-Seats, seat belts and supplemental restraint system1-41

WARNING
• The front air bags ordinarily will not in-
flate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat belts
to help reduce the risk or severity of in-
jury in various kinds of accidents.
• The front passenger air bag and passen-
ger knee air bag will not inflate if the
passenger air bag status light is lit. For
additional information, see “Front pas-
senger air bag and status light” (P. 1-51). •
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 in-
flates. Always sit back against the seat-
back and as far away as practical from
the steering wheel or instrument panel.
Always properly use the seat belts. •
The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
INFINITI Advanced Air Bag System
monitors the severity of a collision and
seat belt usage then inflates the air bags
as needed. Failure to properly wear seat
belts can increase the risk or severity of
injury in an accident.
• The front passenger seat is equipped
with an occupant classification sensor
(weight sensor) that turns the front pas-
senger air bag and passenger knee air
bag OFF under some conditions. This
sensor is 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. For additional in-
formation, see “Front passenger air bag
and status light” (P. 1-51).
• Keep hands on the outside of the steer-
ing wheel. Placing them inside the steer-
ing wheel rim could increase the risk that
they are injured when the front air bag
inflates.

1-42Safety-Seats, seat belts and supplemental restraint system

WARNING
To ensure proper operation of the passen-
ger’s INFINITI 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
9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
• Make sure that there is nothing pressing
against the rear of the seatback, such as
a child restraint installed 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 the center
console or between the seat cushion and
the door. •
If a forward-facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem may determine the seat is occupied
and the passenger air bag may deploy in
a collision. Also the front passenger air
bag status light may not illuminate. For
additional information, see “Child re-
straints” (P. 1-22).
• 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 de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
• Until you have confirmed with a retailer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing 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 mal-
function has occurred and the front pas-
senger air bag status light may illuminate
and the supplemental 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 un-
der U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual still 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 dashboard
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 colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
Safety-Seats, seat belts and supplemental restraint system1-49

The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensor and occupant classifica-
tion sensor (weight sensor). Inflator opera-
tion 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 information from
the sensor, 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 passenger knee air bag may be
automatically turned off under some condi-
tions, depending on the weight detected on
the passenger seat and how the seat belt is
used. If the front passenger air bag and pas-
senger knee air bag is OFF, the front passen-
ger air bag status light will be illuminated. For
additional information, see “Front passenger
air bag and status light” (P. 1-51). 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 that you visit an
INFINITI retailer to obtain information about
the system. If you are considering modifica-
tion of your vehicle due to a disability, youmay also contact INFINITI. Contact informa-
tion 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 the release
of smoke. This smoke is not harmful and does
not indicate a fire. Care should be taken to
not 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
face 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 and passenger
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 prac-
tical away from the steering wheel or instru-
ment 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
front 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 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 sec-
onds if the system is operational.
1-50Safety-Seats, seat belts and supplemental restraint system

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 ve-
hicle 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 repo-
sitioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit an INFINITI re-
tailer for this service.
3. If the light is OFF with no front passengerand no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit 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 instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
• No unauthorized changes should be
made to any components or wiring of the
supplemental 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 front 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 instru-
ment 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 per-
sonal 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 are not specifically designed to
assure proper air bag operation. Addi-
tionally, 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 classification sensor
(weight sensor).
