Installing top tether strap
First, secure the child restraint with the
LATCH lower anchors (2nd row captain’s
or bench outboard seating positions only).
1. If necessary, raise or remove the headrestraint or headrest to position the top
tether strap over the top of the seatback.
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 child restraint is
removed. See “Head restraints/head-
rests” (P.1-13) for head restraint or
headrest adjustment, removal and in-
stallation information.
2. Secure the tether strap to the tether anchor point on the back of each seat-
back behind the child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. Make sure the head restraint
or headrest does not contact the top
tether strap.
If you have any questions when installing a
top tether strap on the rear seat, it is
recommended you visit an INFINITI retailer
for this service.
FORWARD-FACING CHILD RE-
STRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
. The three-point seat belt with Auto-
matic Locking Retractor (ALR) must
be used when installing a child re-
straint. Failure to use the ALR mode
will result in the child restraint not
being properly secured. The restraint
could tip over or be loose and cause
injury to a child in a sudden stop or
collision. Also, it can change the
operation of the front passenger air
bag. See “Front passenger air bag
and status light” (P.1-60)
. When installing a child restraint sys-
tem in the 3rd center position, both
the center seat belt connector tongue
and buckle tongue must be secured.
See “3rd row center seat belt” (P.1-
25).
SSS0640
Forward-facing (front passenger seat) —
step 1
Refer to all Warnings and Cautions in the
“Child safety” and “Child restraints” sections
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child
restraint exceeds 65 lbs (29.5 kg). If the
combined weight of the child and the child
restraint is greater than 65 lbs (29.5 kg), use
the vehicle’s seat belt (not the lower an-
chors) to install the child restraint. Be sure to
follow the child restraint manufacturer’s
instructions for installation.
Follow these steps to install a forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front

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 manufac-
turer’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 portion
of the child’s shoulder. Be sure to follow
the booster seat manufacturer’s instruc-
tions for adjusting the seat belt routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Seat belts” (P.1-18).

7. If the booster seat is installed in the frontpassenger 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” (P.1-60).

PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems.
.Driver and passenger supplemental
front-impact air bag (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 supple-
mental 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
(2nd and 3rd) 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. Under
both side-impact and rollover situations, the
curtain air bags will remain inflated for a
short period of time.
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.1-18) 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.
SUPPLEMENTAL RESTRAINT SYSTEM

SSS0131
SSS0132
WARNING
.The supplemental front air bags or-
dinarily will not inflate in the event of
a side impact, rear impact, rollover, 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 front passenger air bag
status light is lit or if the front
passenger seat is unoccupied. See
“Front passenger air bag and status
light” (P.1-60).
. 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 wheel
or instrument panel. Always use the

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 lbs. (4 kg) on the seatback,
head restraint or in the seatback
pocket.
. Do not store cargo behind the seat
that can press into the seatback.
. 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.
. If a forward facing child restraint is
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts
the instrument panel. If the child
restraint does contact the instrument
panel, the system may determine the
seat is occupied and the passenger air
bag may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. See “Child re-
straints” (P.1-31) for information
about installing and using child re-
straints.
. 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 in
accordance with the above descrip-
tion, it is recommended you visit an
INFINITI retailer to check the pas-
senger seat advanced air bag system.
. Until you have confirmed with your
retailer that your passenger seat
advanced air bag is working properly,
position the occupants in the rear
seating positions. 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 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
monitors information from the Air bag
Control Unit (ACU), seat belt buckle sensors
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 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
information provided by the occupant clas-
sification sensors. If the front passenger air
bag is OFF, the front 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.1-60)
for further details.) One front air bag inflat-
ing does not indicate improper performance
of the system.
If you have any questions about your air bag
system, it is recommended you visit an
INFINITI retailer. If you are considering
modification of your vehicle due to a dis-
ability, 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
Safety — seats, seat belts and supplemental restraint system1-59

1-60Safety — seats, seat belts and supplemental restraint system
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 warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

Front passenger air bag status light
Front passenger air bag and status
light
WARNING
The front passenger air bag is designed
to automatically turn OFF under some
conditions. 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 increasethe risk or severity of injury in an
accident.
Status light:
The front passenger seat is equipped with
the occupant classification sensors (weight
sensors) that turn the front passenger air
bag on or off depending on the weight
applied to the front passenger seat. The
status of the front passenger 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 passen-
ger air bag status light on the instrument
panel 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
light 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
light illuminates 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

1-62Safety — seats, seat belts and supplemental restraint system
may or may not be illuminated, depending on
the size of the child and the type of child
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, the sys-
tem 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
front 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 front passenger air
bag status light will remain off.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air bagwarning light, located in the meter and
gauges area will blink. 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.
Steps:
1. Adjust the seat as outlined. (See “Seats” (P.1-3).) 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. (See “Seat belts” (P.1-18).)
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 locks the classification during driv-
ing so it is important that you confirm that
the front passenger is properly classified
prior to driving. Also, the occupant classifi-
cation sensor system may recalculate the
weight of the occupant when the vehicle
comes to a stop (i.e. stop light, stop sign,
etc.), so the front passenger seat occupant
should continue to remain seated as out-
lined above.
Troubleshooting:
If you think the front passenger air bag
status light is incorrect: 1. If the light is ON with no front passenger and no objects on the front
passenger seat:
This may be due to the following conditions
that may be interfering with the weight
