1-36Safety — Seats, seat belts and supplemental restraint system
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
restraints 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 or headrest to obtain the
correct child restraint 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
child restraint 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 child
restraint fit, try another seating position
or a different child restraint.

Forward-facing — step 3
3. Route the seat belt tongue through the child restraint and insert it into the buckle
until you hear and feel the latch engage.
Be sure to follow the child restraint
manufacturer’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). 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.

Forward-facing — step 4
4. Pull the shoulder belt until the belt is fully extended. At this time, the seat belt
retractor is in the Automatic Locking
Retractor (ALR) mode (child restraint
mode). It reverts to Emergency Locking
Retractor (ELR) mode when the seat belt
is fully retracted.

.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.
Refer to all Warnings and Cautions in the
“Child safety”, “Child restraints” and “Boos-
ter seats” sections 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:

.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 system1-49

1-50Safety — 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 anaccident.

In addition to the above, certain objects
placed on the front passenger seat may also
cause the light to operate as described
above depending on their weight.
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 airbag 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.1-23)
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

If the light illuminates when the FEB system
is ON, it may indicate that the system is
unavailable. See “Forward Emergency Brak-
ing (FEB)” (P.5-106) for more details.
Low fuel warning light
This light illuminates when the fuel in the
tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the 0 (empty) position.
There will be a small reserve of fuel remain-
ing in the tank when the fuel gauge reaches
the 0 position.
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors
the tire pressure of all tires except the spare
tire (if so equipped).
The low tire pressure warning light warns of
low tire pressure and flat tire (if so equipped)
or indicates that the TPMS is not functioning
properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1
second and turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.The “Tire Pressure Low - Add Air” warning
also appears in the vehicle information dis-
play.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label. The low tire pressure
warning light does not automatically turn
off when the tire pressure is adjusted. After
the tire is inflated to the recommended
pressure, the vehicle must be driven at
speeds above 16 MPH (25 km/h) to activate
the TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge to
check the tire pressure.
The “Tire Pressure Low - Add Air” warning is
active as long as the low tire pressure
warning light remains illuminated.
For additional information, see “Vehicle
information display” (P.2-19), “Tire Pressure
Monitoring System (TPMS)” (P.5-5) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-3).
Flat tire warning (if so equipped):
The flat tire warning warns of a flat tire.
If the vehicle is being driven with one or more
flat tires, the low tire pressure warning light
will illuminate continuously and a chime will
sound for 10 seconds. A “Flat Tire - Visit
dealer” warning also appears in the vehicleinformation display.
The chime will only sound at the first
indication of a flat tire and the warning light
will illuminate continuously. When the flat
tire warning is activated, have the system
reset and the tire checked, and replaced if
necessary. It is recommended you visit an
INFINITI retailer for these services. Even if
the tire is inflated to the specified COLD tire
pressure, the warning light will continue to
illuminate until the system is reset.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.6-4).
TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on after the 1 minute. Have the
system checked. It is recommended you visit
an INFINITI retailer for this service. The “Tire
Pressure Low - Add Air” warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P.5-5).
