PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information
concerning 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 sup-
plemental 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 supple-
mental 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
collisions. The curtain air bags are de-
signed to inflate on the side where the
vehicle is impacted.
These supplemental restraint systems are
designed to
supplementthe crash protec-
tion provided by the driver and passenger
seat belts and are not a substitutefor
them. Seat belts should always be cor-
rectly worn and the occupant seated a
suitable distance away from the steering
wheel, instrument panel and door fin-
ishers. (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 warn-
ing light illuminates. The supplemental air
bag warning light will turn off after about
7 seconds if the systems are operational.

WARNING
.The front air bags ordinarily will not
inflate in the event of a side impact, rear
impact, rollover, or lower severity 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 or if the front passenger seat
is unoccupied. See “Front passenger air
bag and status light” (P.1-49).
. 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 advanced air bag system, if you
are unrestrained, leaning forward, sit-
ting 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 sensors 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. Failure 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.1-49).
. 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 positions 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 re-
strained 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-
24) for details.

This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is
designed to meet certification require-
ments under U.S. regulations. It is also
permitted in Canada. All of the informa-
tion, 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
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).
Inflator operation is based on the severity
of a collision and seat belt usage for the
driver. For the front passenger, the occu-
pant classification sensors are also mon-
itored. 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 pas-
senger air bag may be automatically turned
OFF under some conditions, depending on
the information provided by the occupant
classification sensors. If the front passen-
ger air bag is OFF, the 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.1-49) 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, contact an INFINITI retailer. If
you are considering modification of your vehicle due to a disability, you may also
contact an INFINITI retailer. Contact infor-
mation 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 warn-
ing light illuminates. The supplemental air
bag warning light will turn off after about
7 seconds if the system is operational.

Front passenger air bag and status
light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some condi-
tions. 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 severityof injury in an accident.
Status light:
The front passenger air bag status light
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 illuminates depending on
the front passenger seat occupied status.
The light operates as follows:
. Unoccupied passenger seat: The
is
OFF and the front passenger air bag is
OFF and will not inflate in a crash.
. Passenger seat occupied by a small
adult, child or child restraint as out-
lined in this section: The
illumi-
nates to indicate that the front
passenger air bag is OFF and will not
inflate in a crash.
. Occupied passenger seat and the pas-
senger meets the conditions outlined in
this section: The light
is OFF to
indicate that the front passenger air
bag is operational.

Safety —Seats, seat belts and supplemental restraint system1-49

1-50Safety—Seats, seat belts and supplemental restraint system
operated under some conditions as de-
scribed below as permitted by U.S. regula-
tions. If the front passenger air bag is OFF,
it will not inflate in a crash. The driver air
bag and other air bags in your vehicle are
not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automatically
turned OFF.
The occupant classification sensors
(weight sensors) are on the seat cushion
frame under the front passenger seat and
are designed to detect an occupant and
objects on the seat. For example, if a child
is in the front passenger seat, the Ad-
vanced Air Bag System is designed to turn
the passenger air bag OFF in accordance
with the regulations. Also, if a child
restraint of the type specified in the
regulations is on the seat, the occupant
classification sensor can detect it and
cause the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the passenger air bag to be auto- matically turned OFF. For small adults it
may be turned OFF, however, if the
occupant does not sit in the seat properly
(for example, by not sitting upright, by
sitting on an edge of the seat, or by
otherwise being out of position), this could
cause the sensor to turn the air bag OFF.
Always be sure to be seated and wearing
the seat belt properly for the most effective
protection by the seat belt and supple-
mental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear
seat. INFINITI also recommends that appro-
priate child restraints and booster seats be
properly installed in a rear seat. If this is
not possible, the occupant classification
sensors are designed to operate as de-
scribed above to turn the front passenger
air bag OFF for specified child restraints.
Failing to properly secure child restraints
and to use the ALR mode (child restraint
mode) may allow the restraint to tip or
move in an accident or sudden stop. This
can also result in the passenger air bag
inflating in a crash instead of being OFF.
(See
“Child restraints” (P.1-24) for proper
use and installation.)
If the front passenger seat is not occupied, the passenger air bag is 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
sensor. 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 passenger air bag status light,
you can monitor when the front passenger
air bag is automatically turned OFF with the
seat occupied. The light will not illuminate
when the front passenger seat is unoccu-
pied.
If an adult occupant is in the seat but the
passenger air bag status light is illumi-
nated (indicating that the air bag is 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 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 passenger
air bag status light is not illuminated

(indicating 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 passenger air bag status
light is still not illuminated, reposition the
occupant or child restraint in a rear seat.
If the 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
system 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
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 air bag status
light will remain off.
If a malfunction occurs in the front
passenger air bag system, the supplemen-tal air bag warning light, located in the
meter and gauges area will blink. Have the
system checked by an INFINITI retailer.
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
become dangerous projectiles and cause
injury 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 perso-
nal injury.
. Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion 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 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 air bag system may
result in serious personal injury. Tamper-
ing includes changes to the steering
wheel and the instrument panel assem-
bly 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 pas-
senger seat may affect the function of
the air bag system and result in serious
