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.1-9) 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 side air bag inflates, you
may be seriously injured. Be espe-
cially careful with children, who
should always be properly restrained.
Some examples of dangerous riding
positions are shown in the illustra-
tions.

INFINITI ADVANCED AIR BAG
SYSTEM (front seats)
WARNING
To ensure proper operation of the pas-
senger’s 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 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.
Safety — Seats, seat belts and supplemental restraint system1-43

1-44Safety — Seats, seat belts and supplemental restraint system
.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.1-45) 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.

1-48Safety — Seats, seat belts and supplemental restraint system
restraint being used. If the front passenger
air bag status light is not illuminated (in-
dicating 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
front passenger 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
occupant are properly positioned, it is re-
commended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check the system status by using a special
tool. However, until you have confirmed
with your retailer that your air bag is work-
ing 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
passenger seat status. This is normal opera-
tion and does not indicate a malfunction.
If a malfunction occurs in the front passen-
ger 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 you visit
an INFINITI retailer for this service.
Normal operation:
In order for the occupant classification
sensor system to classify the front passen-
ger based on weight, please follow the
precautions and steps outlined below:
Precautions
.
Make sure that there are no objects
weighing 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
object on the seat or floor behind it.
. Make sure that there is no object placed
under the front passenger seat.
. Make sure that the front passenger seat
head restraint does not contact the roof
when adjusting the front passenger seat.
Steps
1. Adjust the seat as outlined in “Seats” (P.1-2). Sit upright, leaning against the
seatback, and centered on the seat
cushion with your feet comfortably ex- tended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in “Seat belts” (P.1-9). Front passenger seat belt
buckle status is monitored by the occu-
pant classification sensor system, and is
used as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fastens his/her 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.
NOTE:
This vehicle’s occupant classification sensor
system generally keeps the classification
locked during driving, so it is important that
you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor may
recalculate the weight of the occupant
under some conditions (both while driving
and when stopped), so the front passenger
seat occupant should continue to remain
seated as outlined above.

Troubleshooting:
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
.Occupant is a small adult - the air bag
light is functioning as intended. The
front passenger air bag is suppressed.
However, if the occupant is not a small
adult, then this may be due to the
following conditions that may be inter-
fering with the weight sensors:
.Occupant is not sitting upright, lean- ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the
floor.
.A child restraint or other object press-ing against the rear of the seatback.
.A rear passenger pushing or pulling onthe back of the front passenger seat.
.Forcing the front seat or seatback
against an object on the seat or floor
behind it.
.An object placed under the frontpassenger seat.
.An object placed between the seat cushion and center console or be-
tween the seat cushion and the door.
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 vehicle 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 ON after this, the
person should be advised not to ride in
the front passenger seat and the vehicle
should be checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
.Small adult or child is not sitting
upright, leaning against the seatback,
and centered on the seat cushion with
his/her feet comfortably extended to
the floor.
.The child restraint is not properly installed as outlined in “Child re-
straints” (P.1-18).
.An object weighing over 9.1 lbs (4 kg) hanging on the seat or placed in the
seatback pocket.
.A child restraint or other object press-ing against the rear of the seatback.
.A rear passenger pushing or pulling on
the back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the frontpassenger seat.
.An object placed between the seat
cushion and center console.
.The front passenger seat head re-straint contacting the roof.
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 vehicle 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
repositioned in the rear seat and the
vehicle should be checked as soon as
possible.
3. If the light is OFF with no front passen- ger and no objects on the front passen-
ger seat, the vehicle should be checked
as soon as possible. It is recommended
