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

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 front
passenger supplemental knee air bag will
not inflate if the passenger air bag status
light is lit. For additional information,
see “Front passenger air bag and status
light” (P. 1-52). •
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 front passenger
supplemental 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 acci-
dent. For additional information, see
“Front passenger air bag and status
light” (P. 1-52).
• 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.
WRS0031
Safety-Seats, seat belts and supplemental restraint system1-43

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 and front pas-
senger supplemental knee air bag may
deploy in a collision. Also the front pas-
senger air bag status light may not illu-
minate. For additional information, see
“Child restraints” (P. 1-21).
• 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.
1-50Safety-Seats, seat belts and supplemental restraint system

The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, door sensors, satellite sensors, the Air
bag Control Unit (ACU), seat belt buckle sen-
sor and occupant classification sensor
(weight 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
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 front passenger supplemental
knee air bag may be automatically turned off
under some conditions, depending on the
weight detected on the passenger seat and
how the seat belt is used. If the front passen-
ger air bag and front passenger supplemental
knee air bag are OFF, the front passenger air
bag status light will be illuminated. For addi-
tional information, see “Front passenger air
bag and status light” (P. 1-52). One front air
bag inflating does not indicate improper per-
formance 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 front passen-
ger supplemental knee air bags, do not pro-
vide 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.

Front passenger air bag and status light
WARNING
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF under
some conditions. Read this section care-
fully 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 an accident.Status light
The front passenger seat is equipped with an
occupant classification sensor (weight sen-
sor) that turns the front passenger air bag
and front passenger supplemental knee air
bag on or off depending on the weight ap-
plied to the front passenger seat. The status
of the front passenger air bag and front pas-
senger supplemental knee 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 on the instrument panel illuminates for
about 7 seconds and then turns off or re-
mains illuminated depending on the front
passenger seat occupied status. The light op-
erates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
In addition to the above, certain objects
placed on the front passenger seat may also
cause the light to operate as described above
depending on their weight.For additional information, see “Normal op-
eration” (P. 1-54) and “Troubleshooting”
(P. 1-55).

the size of the child and the type of child
restraint being used. If the air bag status light
is not illuminated (indicating that the front
passenger air bag and front passenger
supplemental knee 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 prop-
erly, the seat belt is used properly and the
occupant is positioned properly. If the air bag
status light is still not illuminated, reposition
the occupant or child restraint in a rear seat.
If the front passenger air bag status light will
not illuminate even though you believe that
the child restraint, the seat belts and the oc-
cupant are properly positioned, it is recom-
mended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check system status by using a special tool.
However, until you have confirmed with a
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
front passenger air bag status light will take a
few seconds to register a change in the front
passenger seat status. This is normal system
operation and does not indicate a
malfunction.If a malfunction occurs in the front passenger
air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area of the instrument panel, will be
illuminated (blinking or steadily lit). Have the
system checked. It is recommended that you
visit an INFINITI retailer for this service.
Normal operation
In order for the occupant classification sen-
sor system to classify the front passenger
based on weight, please follow the precau-
tions and steps outlined below:
Precautions
• Make sure that there are no objects weigh- ing over 9.1 lbs. (4 kg) hanging on the seat
or placed in the seatback pocket.
• Make sure that a child restraint or other object is not pressing against the rear of the
seatback.
• Make sure that a rear passenger is not pushing or pulling on the back of the front
passenger seat.
• Make sure that the front passenger seat or seatback is not forced back against an ob-
ject on the seat or floor behind it.
• Make sure that there is no object placed under the front passenger seat. Steps
1. Adjust the seat as outlined in the “Seats”
(P. 1-2) section of this manual. Sit upright,
leaning against the seatback, and cen-
tered on the seat cushion with your feet
comfortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” (P. 1-11) section of this
manual. Front passenger seat belt buckle
status is monitored by the occupant clas-
sification system, and is used as an input
to determine occupancy status. So, it is
highly recommended that the front pas-
senger fasten their seat belt.
4. Remain in this position for 30 seconds allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
1-54Safety-Seats, seat belts and supplemental restraint system

• An object placed under the front passengerseat.
• An object placed between the seat cushion and center console.
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 passenger and 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).

injuries. However, an inflating side air bag
and curtain air bag 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, front passenger and rear outboard
occupants seated upright as far as practical
away from the side air bag. Rear seat passen-
gers should be seated as far away as practi-
cal 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 bag
and curtain air bag inflating can increase the
risk of injury if the occupant is too close to, or
is against, these air bag modules during infla-
tion. The side air bag will deflate quickly after
the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags oper-
ate 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.WARNING
• Do not place any objects near the seat-
back of the front and rear seats. Also, do
not place any objects (an umbrella, bag,
etc.) between the front and rear door
finisher and the front and rear seat. Such
objects may become dangerous projec-
tiles and cause injury if a side air bag
inflate.
• Right after inflation, several side air bag
and curtain 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
side air bag and curtain air bag systems.
This is to prevent damage to or acciden-
tal inflation of the side air bag and cur-
tain air bag or damage to the side air bag
and curtain air bag systems.
• Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or side panel. This could af-
fect proper operation of the side air bag
and curtain air bag systems. •
Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front and
rear seats by placing material near the
seatbacks or by installing additional trim
material, such as seat covers, around the
side air bag.
• It is recommended that you visit a
INFINITI retailer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit a
INFINITI retailer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or curtain
air bag system.
* The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner's Manual.
1-58Safety-Seats, seat belts and supplemental restraint system

Driver and front passenger
supplemental knee air bagThe knee air bag is located in the knee bolster,
on the driver’s and passenger’s side.All of the
information, cautions and warnings in this
manual apply and must be followed. The
knee air bag is designed to inflate in higher
severity frontal collisions, although it may in-
flate if the forces in another type of collision
are similar to those of a higher severity fron-
tal impact. It may not inflate in certain
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation. When the knee 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.
The knee air bag helps to cushion the impact
force on the knees of the driver and passen-
ger. It can help reduce serious injuries. How-
ever, an inflating knee air bag may cause
abrasions or other injuries. The knee air bag
provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of this,
the force of the knee air bag inflating can
increase the risk of injury if the occupant is
too close to, or is against, this air bag module
during inflation. The knee air bag will deflate
quickly after the collision is over OR the knee
air bag will remain inflated for a short time.
The knee air bag operates only when the ig-
nition 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.
