children. See “Child restraints” (P.1-19).
A child restraint may be secured in the
vehicle by using either the LATCH (Lower
Anchor and Tethers for CHildren) system or
with the vehicle seat belt. See “Child
restraints” (P.1-19) for more information.
INFINITI recommends that all pre-teens
and children be restrained in the rear seat.
Studies show that children are safer when
properly restrained in the rear seat than in
the front seat.
This is especially important because your
vehicle has a supplemental restraint sys-
tem (Air bag system) for the front passen-
ger. See “Supplemental restraint system ”
(P.1-37).
INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
INFINITI recommends that infants be placed
in child restraints that comply with Federal
Motor Vehicle Safety Standards or Cana-
dian Motor Vehicle Safety Standards. You
should choose a child restraint that fits
your vehicle and always follow the manu-
facturer’s instructions for installation and
use.
SMALL CHILDREN
Children that are over 1 year old and weigh
at least 20 lbs (9 kg) should remain in a
rear-facing child restraint as long as
possible up to the height or weight limit
of the child restraint. Children who outgrow
the height or weight limit of the rear-facing
child restraint and are at least 1 year old
should be secured in a forward-facing child
restraint with a harness. Refer to the
manufacturer’s instructions for minimum
and maximum weight and height recom-
mendations. INFINITI recommends that
small children be placed in child restraints
that comply with Federal Motor Vehicle
Safety Standards or Canadian Motor Vehi-
cle Safety Standards. You should choose a
child restraint that fits your vehicle and
always follow the manufacturer’s instruc-
tions for installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they
reach the maximum height or weight limit
allowed by the child restraint manufac-
turer.
Once a child outgrows the height or weight
limit of the harness-equipped forward- facing child restraint, INFINITI recommends
that the child be placed in a commercially
available booster seat to obtain proper
seat belt fit. For a seat belt to fit properly,
the booster seat should raise the child so
that the shoulder belt is properly posi-
tioned across the chest and the top,
middle portion of the shoulder. The
shoulder belt should not cross the neck
or face and should not fall off the shoulder.
The lap belt should lie snugly across the
lower hips or upper thighs, not the abdo-
men.
A booster seat can only be used in seating
positions that have a three-point type seat
belt. The booster seat should fit the vehicle
seat and have a label certifying that it
complies with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle
Safety Standards. Once the child has
grown so the shoulder belt is no longer
on or near the face and neck, and the lap
belt can be positioned properly across the
lower hips or upper thighs, use the seat
belt without the booster seat.

tion using the seat belts” (P.1-29).
—Even with the INFINITI Advanced Air
Bag System, never install a rear-
facing child restraint in the front
seat. An inflating air bag could
seriously injure or kill a child. A
rear-facing child restraint must only
be used in the rear seat.
—Be sure to purchase a child restraint
that will fit the child and vehicle.
Some child restraints may not fit
properly in your vehicle.
—Child restraint anchor points aredesigned to withstand loads from
child restraints that are properly
fitted.
—Never use the anchor points foradult seat belts or harnesses.
—A child restraint with a top tetherstrap should not be used in the front
passenger seat.
—Keep seatbacks as upright as pos-sible after fitting the child restraint.
—Infants and children should alwaysbe placed in an appropriate child
restraint while in the vehicle. .
When the child restraint is not in use,
keep it secured with the LATCH system
or a seat belt. In a sudden stop or
collision, loose objects can injure occu-
pants or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating surface
and buckles before placing a child in the
child restraint.
This vehicle is equipped with a universal
child restraint anchor system, referred to
as the LATCH (Lower Anchors and Tethers
for CHildren) system. Some child restraints
include rigid or webbing-mounted attach-
ments that can be connected to these
anchors.
For details, see “Lower Anchors and
Tethers for CHildren System (LATCH)” (P.1-
21).
If you do not have a LATCH compatible
child restraint, the vehicle seat belts can
be used.
Several manufacturers offer child restraints for infants and small children of various
sizes. When selecting any child restraint,
keep the following points in mind:
.
Choose only a restraint with a label
certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.
. Check the child restraint in your vehicle
to be sure it is compatible with the
vehicle’s seat and seat belt system.
. If the child restraint is compatible with
your vehicle, place your child in the
child restraint and check the various
adjustments to be sure the child
restraint is compatible with your child.
Choose a child restraint that is de-
signed for your child’ s height and
weight. 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. Canadian law requires the
top tether strap on forward-facing child
restraints be secured to the designated
anchor point on the vehicle.

panel. Always use the seat belts.
. The driver and front passenger seat belt
buckles are equipped with sensors 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. Failure 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.1-44).
. 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
To ensure proper operation of the passen-
ger’
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 luggage behind the seat
that can press into the seatback.
. 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 description,
please take your vehicle to your INFINITI
retailer to check the passenger seat
advanced air bag system.

.Until you have confirmed with your
retailer that your passenger seat ad-
vanced 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
designed to meet certification require-
ments under U.S. regulations. It is also
permitted in Canada. However, 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
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).
Inflator operation is based on the severity
of a collision and seat belt usage for the
driver. For the front passenger, the occu-
pant classification sensors are also mon-
itored. 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 pas-
senger air bag may be automatically turned
OFF under some conditions, depending on
the information provided by the occupant
classification sensors. If the front passen-
ger 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” (P.1-44) for further details.) One front
air bag inflating does not indicate improper
performance of the system.
If you have any questions about your air
bag system, contact an INFINITI retailer. If
you are considering modification of your vehicle due to a disability, you may also
contact an INFINITI retailer. Contact infor-
mation 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 increase
the risk of injury if the occupant is too

operated under some conditions as de-
scribed below as permitted by U.S. regula-
tions. 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.
The occupant classification sensors
(weight sensors) are on the seat cushion
frame under the front passenger seat and
are designed to detect an occupant and
objects on the seat. For example, if a child
is in the front passenger seat, the Ad-
vanced 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, the occupant
classification sensor can detect it 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 auto-matically turned OFF. For small adults it
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
sensors are designed to operate as de-
scribed above to turn the front passenger
air bag OFF for specified child restraints.
Failing to properly secure child restraints
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” (P.1-19) 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

1-46Safety—Seats, seat belts and supplemental restraint system
(indicating 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 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.
If a malfunction occurs in the front
passenger air bag system, the supplemen- tal air bag warning light, located in the
meter and gauges area will blink. Have the
system checked by an INFINITI retailer.
Other supplemental front-impact
air bag precautions
WARNING
. Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may
become dangerous projectiles and cause
injury if the front air bags inflate.
. Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat. Such
objects can damage the seat or occupant
classification sensors (weight sensors).
This can affect the operation of the air
bag system and result in serious perso-
nal injury.
. Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensors. This can also affect the operation of the air bag system and
result in serious personal injury.
. Immediately after inflation, several front
air bag system components will be hot.
Do not touch them; you may severely
burn yourself.
. No unauthorized changes should be
made to any components or wiring of
the air bag system. This is to prevent
accidental inflation of the supplemental
air bag or damage to the supplemental
air bag system.
. Do not make unauthorized changes to
your vehicle’s electrical system, suspen-
sion system or front end structure. This
could affect proper operation of the front
air bag system.
. Tampering with the air bag system may
result in serious personal injury. Tamper-
ing includes changes to the steering
wheel and the instrument panel assem-
bly by placing material over the steering
wheel pad and above the instrument
panel or by installing additional trim
material around the air bag system.
. Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low - Add Air” warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15),“Tire Pressure Mon-
itoring System (TPMS)” (P.5-4) and“Tire
Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire pressure. (See
“TPMS with Tire Infla-
tion Indicator” (P.5-7) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WARNING
. Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. label. The vehicle
weight capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics and could also lead to a
serious accident. Loading beyond
