The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensor and occupant classifica-
tion sensor (weight sensor). Inflator opera-
tion is based on the severity of a collision and
seat belt usage for the driver. For the front
passenger, the occupant classification sensor
is also monitored. Based on information from
the sensor, 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 un-
der some conditions, depending on the
weight detected on the passenger seat and
how the seat belt is used. If the front passen-
ger air bag is OFF, the front passenger air
bag status light will be illuminated. For addi-
tional information, refer to “Front passenger
air bag and status light” in this section. One
front air bag inflating does not indicate im-
proper performance of the system.
If you have any questions about your air bag
system, it is recommended that you visit an
INFINITI retailer to obtain information about
the system. If you are considering modifica-
tion of your vehicle due to a disability, you
may also contact INFINITI. Contact informa-
tion 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 the release
of smoke. This smoke is not harmful and does
not indicate a fire. Care should be taken to
not 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
face 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, other than the driver and passenger
knee 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 prac-
tical away from the steering wheel or instru-
ment 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
front air bag module during inflation.
The front air bags deflate quickly after a col-
lision.
The front air bags operate only when the
ignition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds 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 condi-
tions. 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 con-
cerning 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 sensor (weight sen-
sor) that turns 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 on the instrument panel illuminates for
about 7 seconds and then turns off or re-
mains illuminated depending on the front
passenger seat occupied status. The light op-
erates as follows:
CONDITION
DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
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, refer to “Normal
operation” and “Troubleshooting” in this sec-
tion.
Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle isoperated under some conditions as described
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.
LRS0865
1-54Safety—Seats, seat belts and supplemental restraint system
Page 81 of 580
The purpose of the regulation is to help re-
duce the risk of injury or death from an inflat-
ing air bag to certain front passenger seat
occupants, such as children, by requiring the
air bag to be automatically turned OFF. Cer-
tain sensors are used to meet the require-
ments.
The occupant classification sensor in this ve-
hicle 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 INFINITI Advanced
Air Bag System is designed to turn the front
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
front 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 posi-
tion), this could cause the sensor to turn the
air bag OFF. Always be sure to be seated andwearing 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 properly
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 information, refer to “Child re-
straints” in this section.
If the front passenger seat is not occupied,
the front 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 de-
tected 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, con-
trary to the instructions in this manual. Al-ways be sure that you and all vehicle occu-
pants 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 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 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
restraint being used. If the air bag status light
is not illuminated (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 prop-
erly and the occupant is positioned properly.
If the air bag status light is still not illumi-
nated, reposition the occupant or child re-
straint 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 oc-
cupant are properly positioned, it is recom-
Safety—Seats, seat belts and supplemental restraint system1-55
Page 82 of 580
mended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check system status by using a special tool.
However, until you have confirmed with a
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 front
passenger seat status. This is normal system
operation and does not indicate a malfunc-
tion.
If a malfunction occurs in the front passenger
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 that you
visit an INFINITI retailer for this service.
Normal operation
In order for the occupant classification sen-
sor system to classify the front passenger
based on weight, please follow the precau-
tions 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 in the “Seats” section of this manual. Sit upright, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual. Front
passenger seat belt buckle status is
monitored by the occupant classification
system, and is used as an input to deter-
mine occupancy status. So, it is highly
recommended that the front passenger
fasten their 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. However,
the occupant classification sensor may re-
calculate the weight of the occupant under
some conditions (both while driving and
when stopped), so front passenger seat oc-
cupants should continue to remain seated as
outlined above.
Troubleshooting
If you think the front passenger air bag status
light is incorrect: 1. If the light is ON with an adult occupying the front passenger seat:
∙ Occupant is a small adult — the air bag light is functioning as intended. The front
passenger air bag is suppressed.
1-56Safety—Seats, seat belts and supplemental restraint system
Page 83 of 580
However, if the occupant is not a small adult,
then this may be due to the following condi-
tions 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 cush- ion 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 ve-
hicle 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 ini-
tially.
If the light is still ON after this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
2. 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 condi-
tions 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 in the “Child re-
straints” section of this manual.
∙ An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back 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 cush- ion and center console.
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 ve-
hicle 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 ini-
tially.
If the light is still OFF after this, the small
adult, child or child restraint should be repo-
sitioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit an INFINITI re-
tailer for this service.
Safety—Seats, seat belts and supplemental restraint system1-57

3. If the light is OFF with no front passen-ger and no objects on the front passen-
ger seat the vehicle should be checked. It
is recommended that you visit an
INFINITI retailer for this service.
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 be-
come dangerous projectiles and cause in-
jury if the front air bags inflate.
∙ 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, suspen-
sion system or front end structure. This
could affect proper operation of the
front air bag system.
∙ Tampering with the front air bag system may result in serious personal injury.
Tampering includes changes to the steer-
ing wheel and the instrument panel as-
sembly by placing material over the
steering wheel pad and above the instru-
ment panel or by installing additional
trim material around the air bag system.
∙ Removing or modifying the front passen- ger seat may affect the function of the air
bag system and result in serious personal
injury. ∙ Modifying or tampering with the front
passenger seat may result in serious per-
sonal injury. For example, do not change
the front seats by placing material on the
seat cushion or by installing additional
trim material, such as seat covers, on the
seat that are not specifically designed to
assure proper air bag operation. Addi-
tionally, do not stow any objects under
the front passenger seat or the seat cush-
ion and seatback. Such objects may inter-
fere with the proper operation of the oc-
cupant classification sensor (weight
sensor).
∙ No unauthorized changes should be made to any components or wiring of the seat
belt system. This may affect the front air
bag system. Tampering with the seat belt
system may result in serious personal
injury.

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down
hills.
The gauge needle returns to 0 (Empty) after
the ignition switch is placed in the OFF posi-
tion.
The low fuel warning comes on when the
amount of fuel in the tank is getting low. Refill the fuel tank once the Low Fuel warn-
ing indicator in the vehicle information dis-
play illuminates as indicated by
Low
Fuel.
The
indicates that the fuel-filler door
is located on the driver’s side of the vehicle.
CAUTION
∙ If the vehicle runs out of fuel, theMalfunction Indicator Light (MIL) may
come on. Refuel as soon as possible. After
a few driving trips. the
light should
turn off. If the light remains on after a
few driving trips, have the vehicle in-
spected. It is recommended that you visit
an INFINITI retailer for this service.
∙ For additional information, refer to “Malfunction Indicator Light (MIL)” in
this section.
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the vehicle
can be driven before refueling. The value is
calculated based on recent fuel economy, the
amount of fuel remaining in the fuel tank, and
the actual fuel consumption. Changes in driving patterns or conditions can
cause the DTE value to vary. As a result, the
value displayed may differ from the actual
distance that can be driven.
DTE display will change to “---” when the fuel
level in the tank is getting low, prior to the fuel
gauge reaching 0 (Empty).
NOTE:
∙ The DTE value after refill is estimated
based on recent fuel economy and
amount of fuel added.
∙ If a small amount of fuel is added, or the
ignition is on during refueling, the dis-
play may not be updated.
∙ Conditions that affect the fuel economy
will also affect the estimated DTE value
(city/highway driving, idle time, remote
start time, terrain, seasonal weather,
added vehicle weight, added deflectors,
roof racks, etc.).

∙ Heavy loading of the crossbars has thepotential to affect the vehicle stability
and handling during sudden or unusual
handling maneuvers.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding or
shifting. In a sudden stop or collision, un-
secured cargo could cause personal
injury.
∙ Drive extra carefully when the vehicle is loaded at or near the cargo carrying ca-
pacity, especially if the significant por-
tion of that load is carried on the
crossbars.
CAUTION
∙ Use care when placing or removing itemsfrom the roof rack. If you cannot com-
fortably lift the items onto the roof rack
from the ground, use a ladder or a stool.
Do not apply any load directly to the roof side
rails
A. CrossbarsBmust be installed be-
fore applying load/cargo/luggage to the
roof of the vehicle.
INFINITI accessory crossbars may be avail-
able through an INFINITI retailer. It is recom-
mended that you visit an INFINITI retailer for
additional information. The service load capacity for the roof side
rails is 165 lbs. (74 kg.), however do not ex-
ceed the crossbars load capacity.
Be careful that your vehicle does not exceed
the Gross Vehicle Weight Rating (GVWR) or
its Gross Axle Weight Rating (GAWR front
and rear).
For additional information regarding GVWR
and GAWR, refer to:
∙ F.M.V.S.S. or C.M.V.S.S. certification la- bel (located on the driver’s door pillar).
Installing crossbars (if so equipped)
WARNING
∙ It is recommended that you have the roofrack crossbars installed by an INFINITI
retailer.
∙ Make sure the moonroof (if so equipped) is in the closed position during the instal-
lation process.
∙ Protect the painted area on the vehicle’s roof under the crossbars by placing a
piece of cloth under the cross bars to pre-
vent scratch damage. ∙ Do not load the crossbars more than the
rated load capacity and always distribute
the load uniformly.
The roof rack crossbars may be installed or
removed. Use the provided wrench in the tool
kit to install and remove the crossbars. The
wrench will be in the glove box.

∙When the electronic parking brake is fre-
quently applied and released in a short
period of time, the parking brake may
not operate in order to prevent the park-
ing brake system from overheating. If
this occurs, operate the electronic park-
ing brake switch again after waiting ap-
proximately 1 minute.
∙ If the electronic parking brake must be
applied while driving in an emergency,
pull up and hold the parking brake
switch. When you release the parking
brake switch, the parking brake will be
released.
∙ While pulling up the electronic parking
brake switch during driving, the parking
brake is applied and a chime sounds. The
electronic parking brake indicator light
(red) in the meter and in the parking
brake switch illuminates. This does not
indicate a malfunction. The electronic
parking brake indicator light (red) in the
meter and in the parking brake switch
turns off when the parking brake is re-
leased. ∙
When pulling the electronic parking
brake switch up with the ignition switch
in the OFF or AUTO ACC position, the
parking brake switch indicator light will
continue to illuminate for a short period
of time.
WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
∙ Release the parking brake switch as soon as the engine is delivering enough torque
to the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-
matic brake hold can be displayed on the
vehicle information display.
WARNING
∙ The automatic brake hold function is not
designed to hold the vehicle on a steep hill
or slippery road. Never use the automatic
brake hold when the vehicle is stopped on
a steep hill or slippery road. Failure to do
so may cause the vehicle to move.
∙ When the automatic brake hold function is activated but fails to maintain the ve-
hicle at a standstill, depress the brake
pedal to stop the vehicle. If the vehicle
unexpectedly moves due to outside con-
ditions, the chime may sound and auto-
matic brake hold warning may illuminate
in the vehicle information display.
∙ Be sure to deactivate the automatic brake hold function when using a car
wash or towing your vehicle.

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. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this ca-
pacity. Overloading your vehicle
may result in reduced tire life, un-
safe operating conditions due to
premature tire failure, or unfavor-
able handling characteristics and
could also lead to a serious acci-
dent. Loading beyond the speci-
fied capacity may also result in
failure of other vehicle
components.
∙ Before taking a long trip, or when- ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level. ∙ For additional information re-
garding tires, refer to “Important
