FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
Locking Retractor (ALR) must be used
when installing a child restraint. 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. For addi-
tional information, see “Front passenger
air bag and status light” (P. 1-52). For additional information, see “Child safety”
(P. 1-20) and “Child restraints” (P. 1-22) be-
fore installing a child restraint.
Do not use the lower anchors if the combined
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 vehi-
cle's seat belt (not the lower anchors) to in-
stall 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 passenger
seat:
1.
If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move the
seat to the rearmost position. Child re-
straints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-7).

is interfering with the proper child re-
straint fit, try another seating position or a
different child restraint.3. Route the seat belt tongue through thechild restraint and insert it into the buckle
until you hear and feel the latch engage.
Be sure to follow the child restraint manu-
facturer’s instructions for belt routing.
If the child restraint is equipped with a top
tether strap, route the top tether strap
and secure the tether strap to the tether
anchor point (rear seat installation only).
For additional information, see “Installing
top tether strap” (P. 1-38). Do not install child restraints that require
the use of a top tether strap in seating
positions that do not have a top tether
anchor.

4. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack.
If you have any questions when installing a
top tether strap, it is recommended that you
visit an INFINITI retailer for this service.
WARNING
Child restraint anchorages are designed to
withstand only those loads imposed by
correctly fitted child restraints. Under no
circumstances are they to be used to attach
adult seat belts, or other items or equip-
ment to the vehicle. Doing so could damage
the child restraint anchorages. The child re-
straint will not be properly installed using
the damaged anchorage, and a child could
be seriously injured or killed in a collision.
BOOSTER SEATS
For additional information on installing a
booster seat in your vehicle, follow the in-
structions outlined in this section.
Precautions on booster seats
WARNING
If a booster seat and seat belt are not used
properly, the risk of a child being injured or
killed in a sudden stop or collision greatly
increases:
– Make sure the shoulder portion of the
belt is away from the child's face and
neck and the lap portion of the belt does
not cross the stomach.
– Make sure the shoulder belt is not be-
hind the child or under the child's arm.
– A booster seat must only be installed in a
seating position that has a lap/shoulder
belt.

Booster seat installation
WARNING
To avoid injury to child, do not use the lap/
shoulder belt in the Automatic Locking Re-
tractor (ALR) mode when using a booster
seat with the seat belts.
For additional information, see “Child safety”
(P. 1-20), “Child restraints” (P. 1-22) and
“Booster seats” (P. 1-38) before installing a
child restraint.
Follow these steps to install a booster seat in
the rear seats or in the front passenger seat:
1.If you must install a booster seat in the
front seat, move the seat to the rearmost
position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manufac-
turer’s instructions. 3. The booster seat should be positioned on
the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional informa-
tion, see “Head restraints/headrests”
(P. 1-7).

If the seating position does not have an
adjustable head restraint/headrest and it
is interfering with the proper booster seat
fit, try another seating position or a differ-
ent 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 manufacturer’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 posi-
tioned across the top, middle portion 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 in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” (P. 1-16). 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in 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 being
used. For additional information, see
“Front passenger air bag and status light”
(P. 1-52).

SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
Safety-Seats, seat belts and supplemental restraint system1-41

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. 1-22).
• 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.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the interfer-
ence) separate from the registered key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
