1-14Safety—Seats, seat belts and supplemental restraint system
WARNING
. Every person who drives or rides in this
vehicle should use a seat belt at all
times. Children should be properly re-
strained in the rear seat and, if appro-
priate, in a child restraint.
. The seat belt should be properly ad-
justed to a snug fit. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the chance
or severity of injury in an accident.
Serious injury or death can occur if the
seat belt is not worn properly.
. Always route the shoulder belt over your
shoulder and across your chest. Never
put the belt behind your back, under
your arm or across your neck. The belt
should be away from your face and neck,
but not falling off your shoulder.
. Position the lap belt as low and snug as
possible AROUND THE HIPS, NOT THE
WAIST. A lap belt worn too high could
increase the risk of internal injuries in an
accident.
. Be sure the seat belt tongue is securely
fastened to the proper buckle. .
Do not wear the seat belt inside out or
twisted. Doing so may reduce its effec-
tiveness.
. Do not allow more than one person to
use the same seat belt.
. Never carry more people in the vehicle
than there are seat belts.
. If the seat belt warning light glows
continuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked by an INFINITI retailer.
. No changes should be made to the seat
belt system. For example, do not modify
the seat belt, add material or install
devices that may change the seat belt
routing or tension. Doing so may affect
the operation of the seat belt system.
Modifying or tampering with the seat
belt system may result in serious perso-
nal injury.
. Once a seat belt pretensioner has
activated, it cannot be reused and must
be replaced together with the retractor.
See an INFINITI retailer.
. Removal and installation of pretensioner
system components should be done by an INFINITI retailer.
. All seat belt assemblies, including re-
tractors and attaching hardware, should
be inspected after any collision by an
INFINITI retailer. INFINITI recommends
that all seat belt assemblies in use
during a collision be replaced unless
the collision was minor and the belts
show no damage and continue to oper-
ate properly.
Seat belt assemblies not in use during a
collision should also be inspected and
replaced if either damage or improper
operation is noted.
. All child restraints and attaching hard-
ware should be inspected after any
collision. Always follow the restraint
manufacturer’s inspection instructions
and replacement recommendations. The
child restraints should be replaced if
they are damaged.

8. After attaching the child restraint, test
it before you place the child in it. Push
it from side to side while holding the
child restraint near the seat belt path.
The child restraint should not move
more than 1 inch (25 mm), from side to
side. Try to tug it forward and check to
see if the belt holds the restraint in
place. If the restraint is not secure,
tighten the seat belt as necessary, or
put the restraint in another seat and
test it again. You may need to try a
different child restraint. Not all child
restraints fit in all types of vehicles. 9. Check to make sure the child restraint
is properly secured prior to each use. If
the seat belt is not locked, repeat steps
2 through 8.

10. If the child restraint is installed in the
front passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should illuminate. If this light is not
illuminated, see “Front passenger air
bag and status light” in this section.
Move the child restraint to another
seating position. Have the system
checked by an INFINITI retailer.
After the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

3. The booster seat should be positioned
on the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint or headrest to obtain the
correct booster seat fit. If the head
restraint or headrest is removed, store
it in a secure place. Be sure to reinstall
the head restraint or headrest when
the booster seat is removed. See“Head
restraints” earlier in this section or
“Adjustable headrest” earlier in this
section for head restraint or headrest
adjustment, removal and installation
information. If the seating position does not have an
adjustable head restraint or headrest
and it is interfering with the proper
booster seat fit, try another seating
position or a different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be
sure to follow the booster seat manu-
facturer’s instructions for adjusting the
seat belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up
extra slack. Be sure the shoulder belt is
positioned across the top, middle por-
tion of the child’s shoulder. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
6. Follow the warnings, cautions and
instructions for properly fastening a
seat belt shown in the “Seat belts”
earlier in this section.

7. If the booster seat is installed in the
front passenger seat, push the ignition
switch to the ON position. The front
passenger air bag status light
may
or may not illuminate depending on the
size of the child and the type of booster
seat used. (See “Front passenger air
bag and status light” later in this
section.)

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” 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 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 inflates. Always sit
back against the seatback and as far-
away as practical from the steering

dual stage air bag inflators. The system
monitors 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 in-
formation 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. Addi-
tionally, the front passenger air bag may
be automatically turned OFF under some
conditions, depending on the information
provided by the occupant classification
sensor. If the front passenger 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” later in this section
for further details.) One front air bag
inflating does not indicate improper per-
formance 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 increasethe 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.

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 severity of injury in an accident.
Status light:GUID-4D508F5D-FA8E-49D6-A9E2-6F8E76C17033
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 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.
Front passenger air bag:
GUID-4D508F5D-FA8E-49D6-A9E2-6F8E76C17033

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
sensor is designed to operate as described
above to turn the front passenger air bag
OFF for specified child restraints. Failing to
properly secure child restrains 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 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 inflatein 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.

WARNING
.The pretensioners cannot be reused after
activation. They must be replaced to-
gether with the retractor and buckle as a
unit.
. If the vehicle becomes involved in a
collision but a pretensioner is not
activated, be sure to have the preten-
sioner system checked and, if necessary,
replaced by an INFINITI retailer.
. No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental activa-
tion of the pretensioners. Tampering
with the pretensioner system may result
in serious personal injury.
. Work around and on the pretensioner
system should be done by an INFINITI
retailer. Installation of electrical equip-
ment should also be done by an INFINITI
retailer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system. .
If you need to dispose of the preten-
sioner or scrap the vehicle, contact an
INFINITI retailer. Correct pretensioner
disposal procedures are set forth in the
appropriate INFINITI Service Manual.
Incorrect disposal procedures could
cause personal injury.
The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat
belt retractor, it helps tighten the seat belt
when the vehicle 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
released 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 breath-
ing condition should get fresh air promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest. The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. (See “Supplemental
air bag warning light” later in this section
for more details.) If the supplemental air
bag warning light indicates there is a
malfunction, have the system checked by
an INFINITI retailer.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.
