. 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

indicate that the front passenger air bag
is operational.
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.1-62)
and “Troubleshooting” (P.1-62) in this sec-
tion.
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 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 Advanced Air Bag
System is designed to turn the passenger
air bag OFF in accordance with the regula-
tions. Also, if a child restraint of the type
specified in the regulations is on the seat, the
occupant classification sensors 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 automatically
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 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 sensors
are designed to operate as described above
to turn the front passenger air bag OFF for
specified child restraints. Failing to properly
secure child restrains and to use the ALR
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.1-31) 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 de-
tected by the occupant classification sen-
sors. 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 prop-
erly.
Using the front 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 unoccupied.
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.
If a child restraint must be used in the front
seat, the front passenger air bag status light
Safety — seats, seat belts and supplemental restraint system1-61

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

sensors:
.An object weighing over 9.1 lbs (4 kg)
hanging on the seat or placed in the
seatback pocket.
. A child restraint or other object pressing
against the rear of the seatback.
. A rear passenger pushing or pulling on
the back of the front passenger seat.
. Forcing the front seat or seatback
against an object on the seat or floor
behind it.
. An object placed under the front passen-
ger seat.
. An object placed between the seat
cushion and center console or between
the seat cushion and the door.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Restart
the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, it is
recommended that the vehicle be checked
by an INFINITI retailer as soon as possible.
2. If the light is ON with an adult occupy- ing the front passenger seat: .
Occupant is a small adult — the front
passenger air bag status light is func-
tioning as intended. The front passenger
air bag is suppressed.
However, if the occupant is not a small adult,
then this may be due to the following
conditions that may be interfering with the
weight sensors:
. Occupant is not sitting upright, leaning
against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.
. A child restraint or other object pressing
against the rear of the seatback.
. A rear passenger pushing or pulling on
the back of the front passenger seat.
. Forcing the front seat or seatback
against an object on the seat or floor
behind it.
. An object placed under the front passen-
ger seat.
. An object placed between the seat
cushion and center console or between
the seat cushion and the door.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Restart
the vehicle and wait 1 minute. NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, the person
should be advised not to ride in the front
passenger seat and it is recommended that
the vehicle be checked by an INFINITI
retailer as soon as possible.
3. If the light is OFF with a small adult, child or child restraint occupying the
front passenger seat.
This may be due to the following
conditions that may be interfering with
the weight sensors:
. Small adult or child is not sitting upright,
leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.
. The child restraint is not properly in-
stalled, as outlined. (See “Child re-
straints” (P.1-31).)
. An object weighing over 9.1 lbs (4 kg)
hanging on the seat or placed in the
seatback pocket.
. A child restraint or other object pressing
against the rear of the seatback.
. A rear passenger pushing or pulling on
the back of the front passenger seat.

air bag precautions
WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment 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 in-
jury 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 personal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification 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 supplemental 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,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
. Tampering with the air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly 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
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury.
. Modifying or tampering with the
front passenger seat may result in
serious personal injury. For example,

ROOF RACK
Do not apply any load directly to the roof
side rails. Cross bars must be installed before
applying load/cargo/luggage to the roof of
the vehicle. Genuine INFINITI accessory
cross bars are available through an INFINITI
retailer. It is recommended that you visit an
INFINITI retailer for additional information.
The service load capacity for the roof side
rails is 221 lb (100 kg), however do not
exceed the accessory cross bars load capa-
city.
Be careful that your vehicle does not exceed
the Gross Vehicle Weight Rating (GVWR) or
its Gross Axle Weight Rating (GAWR frontand rear). The GVWR and GAWR are
located on the F.M.V.S.S. or C.V.M.S.S.
certification label (located on the driver’s
door pillar). For additional information re-
garding GVWR and GAWR, refer to “Vehicle
loading information” (P.10-15).
WARNING
.
Always install the cross bars onto the
roof side rails before loading cargo of
any kind. Loading cargo directly onto
the roof side rails or the vehicle’s roof
may cause vehicle damage.
. Drive extra carefully when the vehicle
is loaded at or near the cargo carrying
capacity, especially if the significant
portion of that load is carried on the
roof rack.
. Heavy loading of the roof rack has
the potential to affect the vehicle
stability and handling during sudden
or unusual handling maneuvers.
. Roof rack load should be evenly
distributed.
. Do not exceed maximum roof rack
load weight capacity.
. Properly secure all cargo with ropes
or straps to help prevent it from
sliding or shifting. In a sudden stop or collision, unsecured cargo could
cause personal injury.
Instruments and controls2-67

If you have a flat tire, see “Flat tire” (P.6-3).
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 informa-
tion 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.2-16), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-5) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires (in-
cluding the spare) often and always
prior to long distance trips. The
recommended tire pressure specifica-
tions are shown on the Tire andLoading 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 when
driven over potholes or other ob-
jects 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 un-
der inflation, may adversely affect tire life and vehicle handling.
WARNING
.
Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rat-
ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. certifica-
tion 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 con-
ditions due to premature tire
failure, or unfavorable handling
characteristics and could also
lead to a serious accident.
Loading beyond the specified
capacity may also result in fail-
ure of other vehicle compo-
nents.
. Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
