PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the following systems.
●Driver and passenger supplemental front-
impact air bag (INFINITI Advanced Air Bag
System)
● Front seat-mounted side-impact supplemen-
tal air bag
● Roof-mounted curtain side-impact supple-
mental air bag
● Seat belt with pretensioner cap
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 supplemental
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 front seat side-impact
supplemental air bags are designed to inflate
on the side where the vehicle is impacted. Roof-mounted curtain side-impact supplemen-
tal 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 designed to inflate on the side where
the vehicle is impacted.
These supplemental restraint systems are de-
signed to supplement the crash protection pro-
vided by the driver and passenger seat belts
and are not a substitute for them. Seat belts
should always be correctly worn and the occu-
pant seated a suitable distance away from the
steering wheel, instrument panel and door fin-
ishers. (See “SEAT BELTS” earlier in this section
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 posi-
tion, the supplemental air bag warning light illu-
minates. 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, roll-
over, or lower severity frontal collision. Al-
ways 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”
later in this section.
● 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 Ad-
vanced Air Bag System, if you are unre-
strained, 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. Al-
ways use the seat belts.

information from the crash zone sensor, the Air
bag Control Unit (ACU), the diagnosis sensor
unit, seat belt buckle sensors and the occupant
classification sensor (pattern sensor). Inflator
operation 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
sensors, only one front air bag may inflate in a
crash, depending on the crash severity and
whether the front occupants are belted or un-
belted. Additionally, the front passenger air bag
may be automatically turned OFF under some
conditions, depending on the information pro-
vided by the occupant classification sensor. If
the front passenger air bag is OFF, the passen-
ger air bag status light will be illuminated (if the
seat is unoccupied, the light will not be illumi-
nated, but the air bag will be off). (See “Front
passenger air bag and status light” later in this
section for further details.) One front air bag
inflating does not indicate improper perfor-
mance of the system.
If you have any questions about your air bag
system, contact INFINITI or an INFINITI retailer. If
you are considering modification of your vehicle
due to a disability, you may also contact
INFINITI. 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 colli-
sion.
The front air bags operate only when the ignition
switch is in the ON position.
After pushing the ignition switch to the ON posi-
tion, the supplemental air bag warning light illu-
minates. 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 au-
tomatically turn OFF under some conditions.
Read this section carefully to learn how it oper-
ates. Proper use of the seat, seat belt and child
restraints is necessary for most effective pro-
tection. 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 an accident.Status light :
The front passenger air bag status light
is located under the climate controls. 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
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 outlined in this
section: The
illuminates to indicate
that the front passenger air bag is OFF and
will not inflate in a crash.
● Occupied passenger seat and the passenger
meets the conditions outlined in this sec-
tion: The light
is OFF to indicate that
the front passenger air bag is operational.
Front passenger air bag :
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as described
below as permitted by U.S. regulations. 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 sensor (pattern sen-
sor) is in the front passenger seat cushion and
is designed to detect an occupant and objects
on the seat. For example, if a child is in the front
passenger seat, the Advanced 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 sen-
sor 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 automatically 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 supplemental air bag.

1-44Safety — Seats, seat belts and supplemental restraint system

INFINITI recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the front
passenger air bag OFF for specified child re-
straints. Failing to properly secure child re-
strains 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”
earlier in this section for proper use and instal-
lation.)
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 occu-pied. The light will not illuminate when the front
passenger seat is unoccupied.
If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(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 passen-
ger 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 yourretailer 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 un-
occupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag warn-
ing 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 occu-
pant and the steering wheel or instrument
panel. Such objects may become dangerous
projectiles and cause injury if the front air
bag inflates.

FRONT SEAT-MOUNTED SIDE-IMPACT
SUPPLEMENTAL AIR BAG AND
ROOF-MOUNTED CURTAIN SIDE-
IMPACT 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. These
systems are designed to meet voluntary guide-
lines to help reduce the risk of injury to occu-
pants.However, all of the information, cautions
and warnings in this manual still 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 side impact. They are
designed to inflate on the side where the
vehicle is impacted. They may not inflate in
certain side collisions on the side where the
vehicle is impacted.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain air
bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard, fol-
lowed 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
and pelvis of the front occupants. Curtain air
bags help to cushion the impact force to the
head of occupants in the front and rear out-
board seating positions. They can help save
lives and reduce serious injuries. However, in-
flating side air bags and curtain air bags may
cause abrasions or 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 bags. 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 bags and curtain
air bags will deflate quickly after the collision is
over.
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 posi-
tion, the supplemental air bag warning light illu-
minates. The air bag warning light will turn off
after about 7 seconds if the systems are opera-
tional.

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 activates, smoke is re-
leased 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 al-
low the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
The supplemental air bag warning light
is used to indicate malfunctions in the preten-
sioner system. If the operation of the supple-
mental air bag warning light indicates there is a
malfunction (See “SUPPLEMENTAL AIR BAG
WARNING LIGHT” in this section), have the
system checked by an INFINITI retailer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.

When the ignition switch is in the ON position,
the supplemental air bag warning light illumi-
nates for about 7 seconds and then turns off.
This means the system is operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain air bag and
pretensioner systems need servicing:
●The supplemental air bag warning light re-
mains on approximately 7 seconds after the
ignition switch is pushed to the ON position.
● The supplemental air bag warning light
flashes intermittently.
● The supplemental air bag warning light does
not come on at all.
Under these conditions, the front air bag, side
air bag, and curtain air bag or pretensioner
systems may not operate properly. They must
be checked and repaired. Take your vehicle to
the nearest INFINITI retailer.WARNING
If the supplemental air bag warning light is on,
it could mean that the front air bag, side air
bag, curtain air bag and/or pretensioner sys-
tems will not operate in an accident. To help
avoid injury to yourself or others, have your
vehicle checked by an INFINITI retailer as soon
as possible.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain air
bags and pretensioners are designed to acti-
vate on a one-time-only basis. As a reminder,
unless it is damaged, the supplemental air bag
warning light will remain illuminated after infla-
tion has occurred. Repair and replacement of
these systems should be done only by an
INFINITI retailer.
When maintenance work is required on the
vehicle, the front air bags, side air bags, curtain
air bags, pretensioners and related parts
should be pointed out to the person conducting
the maintenance. The ignition switch should
always be in the LOCK position when working
under the hood or inside the vehicle.
WARNING
● Once a front air bag, side air bag or curtain
air bag has inflated, the air bag module will
not function again and must be replaced.
Additionally, the activated pretensioner
must also be replaced. The air bag module
and pretensioner system should be replaced
by an INFINITI retailer. The air bag module
and pretensioner system cannot be
repaired.
● The front air bag, side air bag, curtain air bag
systems and the pretensioner system
should be inspected by an INFINITI retailer if
there is any damage to the front end or side
portion of the vehicle.
● If you need to dispose of a supplemental air
bag or pretensioner systems or scrap the
vehicle, contact an INFINITI retailer. Correct
supplemental air bag and pretensioner sys-
tem disposal procedures are set forth in the
appropriate INFINITI Service Manual. Incor-
rect disposal procedures could cause per-
sonal injury.
