and a child could be seriously injured or
killed in a collision.

The child restraint top tether strap must be
used when installing forward-facing child
restraints with the seat belts.
First, secure the child restraint with the seat
belt.
1. Position the top tether strap

over the

seatback.
If necessary, raise or remove the head
restraint 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.

8) for head restraint or headrest adjust-
ment, removal and installation informa-
tion.

2. Secure the tether strap to the tether

anchor point

as shown.

3. 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 you
visit an INFINITI retailer for this service.

BOOSTER SEATS

For additional information on installing a
booster seat in your vehicle, follow the
instructions 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
behind 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.

LRS0455

Booster seats of various sizes are offered by
several manufacturers. When selecting any
booster seat, keep the following points in
mind:

.

Choose only a booster seat with a label

certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.

.

Check the booster seat in your vehicle to

be sure it is compatible with the vehicle’s
seat and seat belt system.

.

Make sure the child’s head will be

properly supported by the booster seat
or vehicle seat. The seatback must be at
or above the center of the child’s ears.
For example, if a low back booster seat

is chosen, the vehicle seatback must be

at or above the center of the child’s ears.
If the seatback is lower than the center
of the child’s ears, a high back booster
seat

should be used.

LRS0464

.

If the booster seat is compatible with

your vehicle, place your child in the
booster seat and check the various
adjustments to be sure the booster seat
is compatible with your child. Always
follow all recommended procedures.

All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved child
restraint at all times while the vehicle is
being operated.

The instructions in this section apply to
booster seat installation in the rear seats or
the front passenger seat.

Booster seat installation

WARNING

To avoid injury to child, do not use the
lap/shoulder belt Automatic Locking
Retractor (ALR) mode when using a
booster seat with the seat belts.

For additional information, refer to all
Warnings and Cautions in the “Child safety”,
“Child restraints” and “Booster seats” sec-
tions earlier in this section before installing a
child restraint.
Follow these steps to install a booster seat in
the rear seat or in the front passenger seat:

SSS0640

1.

If you must install a booster seat in the
front seat, move the seat to the rear-
most position.

2. Position the booster seat on the seat.

Only place it in a forward-facing direc-
tion. Always follow the booster seat
manufacturer’s instructions.

LRS0454

Front passenger position

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/headrests” (P.1-8) for head
restraint or headrest adjustment, re-
moval 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 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

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.1-12) 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

.

The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity 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. See “Front passenger air
bag and status light” (P.1-50).

.

The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor. The
front air bags inflate with great
force. Even with the INFINITI Ad-
vanced 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
seat belts.

Safety — Seats, seat belts and supplemental restraint system

.

The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.

.

The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. These sensors are 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 accident. See “Front
passenger air bag and status light”
(P.1-50).

.

Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could increase
the risk of injury if the front air bag
inflates.

WARNING

.

Never let children ride unrestrained
or extend their hands or face out of
the window. Do not attempt to hold
them in your lap or arms. Some
examples of dangerous riding posi-
tions are shown in the illustrations.

.

Children may be severely injured or
killed when the front air bags, side air
bags or curtain air bags inflate if they
are not properly restrained. Pre-
teens and children should be properly
restrained in the rear seat, if possible.

.

Even with the INFINITI Advanced Air
Bag System, never install a rear-
facing child restraint in the front
seat. An inflating front air bag could
seriously injure or kill your child. See

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 supplemental side air bag
inflates, you may be seriously injured.
Be especially careful with children,
who should always be properly re-
strained. Some examples of danger-
ous riding positions are shown in the

WARNING

To ensure proper operation of the pas-
senger’s Advanced Air Bag System, ob-
serve 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.

.

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.1-50) 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.

Safety — Seats, seat belts and supplemental restraint system

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 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 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 increase
the risk or severity of injury in an

accident.

Status light:

The front passenger seat is equipped with an
occupant classification sensors (weight sen-
sors) 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 passenger air bag status
light illuminates for about 7 seconds and
then turns off or remains illuminated de-
pending on the front passenger seat occu-
pied status. The light operates as follows:

For additional information related to the
normal operation and troubleshooting of
this occupant classification sensor system,
please refer to “Normal operation” (P.1-54)
and “Troubleshooting” (P.1-55).

Front passenger air bag:

The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S.
regulations. If the front passenger air bag
is OFF, it will not inflate in a crash. The driver
air bag and other air bags in your vehicle are
not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requiring
the air bag to be automatically turned OFF.
Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child is in the
front passenger seat, the Advanced Air Bag
System is designed to turn the passenger air

bag OFF in accordance with the regulations.
Also, if a child restraint of the type specified
in the regulations is on the seat, its weight
and the child’s weight can be detected and
cause the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not cause
the passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant takes
his/her weight off the seat cushion (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 supplemental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be prop-
erly 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 as required by the
regulations. Failing to properly secure child
restraints and to use the ALR mode may
allow the restraint to tip or move in a
collision or sudden stop. This can also result

in the passenger air bag inflating in a crash
instead of being OFF. For additional infor-
mation, refer to “Child restraints” (P.1-22)
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’s weight
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 front passenger air bag status
light, you can monitor when the front
passenger air bag is automatically turned
OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is
illuminated (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 or
not using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending on
the size of the child and the type of child

Safety — Seats, seat belts and supplemental restraint system

1-53

Safety — 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 system
operation and does not indicate a malfunc-
tion.
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.1-12). 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.
