Front passenger air bag and status light
WARNING
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF under
some conditions. Read this section care-
fully 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 sensor (weight sen-
sor) that turns the front passenger air bag
and front passenger supplemental knee air
bag on or off depending on the weight ap-
plied to the front passenger seat. The status
of the front passenger air bag and front pas-
senger supplemental knee 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
remains illuminated depending on the front
passenger seat occupied status. The light
operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE 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, see “Normal opera-
tion” (P. 1-54) and “Troubleshooting” (P. 1-55).
LRS0865

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 front
passenger air bag and front passenger
supplemental knee 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 prop-
erly, the seat belt is used properly and the
occupant is positioned properly. If the 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 oc-
cupant are properly positioned, it is recom-
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
malfunction.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 weigh- ing 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 ob-
ject 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”
(P. 1-2) section of this manual. Sit upright,
leaning against the seatback, and cen-
tered on the seat cushion with your feet
comfortably 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” (P. 1-12) section of this
manual. Front passenger seat belt buckle
status is monitored by the occupant clas-
sification system, and is used as an input
to determine occupancy status. So, it is
highly recommended that the front pas-
senger 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.
1-54Safety-Seats, seat belts and supplemental restraint system

• An object placed under the front passengerseat.
• An object placed between the seat cushion 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 initially.
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.
3. If the light is OFF with no front passenger and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit an INFINITI
retailer as soon as possible.
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.
• Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely 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
steering wheel and the instrument panel
assembly 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 pas-
senger 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 addi-
tional trim material, such as seat covers,
on the seat that are not specifically
designed to assure proper air bag opera-
tion. Additionally, do not stow any ob-
jects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classification
sensor (weight sensor).
1-56Safety-Seats, seat belts and supplemental restraint system

•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.
• It is recommended that you visit an
INFINITI retailer for work on and around
the front air bags. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modified
or disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag system.
• A cracked windshield should be replaced
immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.
*The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.
Front and rear outboard
seat-mounted side-impact
supplemental air bag and
roof-mounted curtain side-impact
and rollover supplemental air bag
systems
The side air bags are located in the outside of
the seatback of the front and rear outboard
seats. The curtain air bags are located in the
side roof rails. All of the information, cau-
tions and warnings in this manual must be
followed. The side air bags and curtain air
bags are designed to inflate in higher severity side collisions, although they may inflate if
the forces in another type of collision are
similar to those of a higher severity impact.
They are designed to inflate on the side
where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near roll-
overs. As a result, certain vehicle movements
(for example, during severe off-roading) may
cause the curtain air bags to inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain
air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard, fol-
lowed by the 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.
Side air bags, along with the use of seat belts,
help to cushion the impact force on the chest
and pelvic area of the front and rear outboard
occupants. Curtain air bags help to cushion
the impact force to the head of occupants in
the front and rear outboard seating positions.
LRS3142
Safety-Seats, seat belts and supplemental restraint system1-57

They can help save lives and reduce serious
injuries. However, an inflating side air bag
and curtain air bag may cause abrasions or
other injuries. Side air bags and curtain air
bags do not provide restraint to the lower
body.
The seat belts should be correctly worn and
the driver, front passenger and rear outboard
occupants seated upright as far as practical
away from the side air bag. Rear seat passen-
gers should be seated as far away as practi-
cal from the door finishers and side roof rails.
The side air bags and curtain air bags inflate
quickly in order to help protect the occupants.
Because of this, the force of the side air bag
and curtain air bag inflating can increase the
risk of injury if the occupant is too close to, or
is against, these air bag modules during infla-
tion. The side air bag will deflate quickly after
the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags oper-
ate 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.WARNING
• Do not place any objects near the seat-
back of the front and rear seats. Also, do
not place any objects (an umbrella, bag,
etc.) between the front and rear door
finisher and the front and rear seat. Such
objects may become dangerous projec-
tiles and cause injury if a side air bag
inflate.
• Right after inflation, several side air bag
and curtain 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
side air bag and curtain air bag systems.
This is to prevent damage to or acciden-
tal inflation of the side air bag and cur-
tain air bag or damage to the side air bag
and curtain air bag systems.
• Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or side panel. This could af-
fect proper operation of the side air bag
and curtain air bag systems. •
Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front and
rear seats by placing material near the
seatbacks or by installing additional trim
material, such as seat covers, around the
side air bag.
• It is recommended that you visit an
INFINITI retailer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit an
INFINITI retailer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or curtain
air bag system.
* The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner's Manual.
1-58Safety-Seats, seat belts and supplemental restraint system

Driver and front passenger
supplemental knee air bagsThe knee air bag is located in the knee bolster,
on the driver’s and passenger’s side.All of the
information, cautions and warnings in this
manual apply and must be followed. The
knee air bag is designed to inflate in higher
severity frontal collisions, although it may
inflate if the forces in another type of collision
are similar to those of a higher severity fron-
tal impact. It may not inflate in certain
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation. When the knee 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.
The knee air bag helps to cushion the impact
force on the knees of the driver and passen-
ger. It can help reduce serious injuries. How-
ever, an inflating knee air bag may cause
abrasions or other injuries. The knee air bag
provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of this,
the force of the knee air bag inflating can
increase the risk of injury if the occupant is
too close to, or is against, this air bag module
during inflation. The knee air bag will deflate
quickly after the collision is over OR the knee
air bag will remain inflated for a short time.
The knee air bag operates only when the ig-
nition 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.

• Do not make unauthorized changes to
your vehicle's electrical system or sus-
pension system. This could affect proper
operation of the knee air bag system.
• Tampering with the knee air bag system
may result in serious personal injury. For
example, do not change the driver knee
bolster or install additional trim material
around the knee air bag. •
It is recommended that you visit an
INFINITI retailer for work on and around
the knee air bag. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
SRS wiring harnesses* should not be
modified or disconnected. Unauthorized
electrical test equipment and probing
devices should not be used on the knee
air bag system.

yellow or orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the knee air bag
system and guide the buyer to the appropri-
ate sections in this manual.
Seat belt with pretensioner(s) (front
seats and rear outboard seats)
WARNING
• The pretensioner(s) cannot be reused af-
ter activation. They must be replaced to-
gether with the retractor and buckle as a
unit. •
If the vehicle becomes involved in a colli-
sion but pretensioner(s) are not acti-
vated, be sure to have the pretensioner
system checked and, if necessary, re-
placed. It is recommended that you visit
an INFINITI retailer for this service.
• No unauthorized changes should be
made to any components or wiring of the
pretensioner system. This is to prevent
damage to or accidental activation of the
pretensioner(s). Tampering with the pre-
tensioner system may result in serious
personal injury.
• It is recommended that you visit an
INFINITI retailer for work on and around
the pretensioner system. It is also recom-
mended that you visit an INFINITI re-
tailer for installation of electrical equip-
ment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
• If you need to dispose of the pretension-
er(s) or scrap the vehicle, it is recom-
mended that you visit an INFINITI re-
tailer for this service. Incorrect disposal
procedures could cause personal injury.
1-60Safety-Seats, seat belts and supplemental restraint system

The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat belt
retractor, the pretensioner(s) help tighten
the seat belt when the vehicle becomes in-
volved in certain types of collisions, helping
to restrain front and rear outboard seat
occupants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt anchor
affixed to the floor of the vehicle. These seat
belts are used the same way as conventional
seat belts.
When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. 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.
After the pretensioner(s’) activation, load lim-
iters allow the seat belt to release webbing
(if necessary) to reduce forces against the
chest.The supplemental air bag warning lightis used to indicate malfunctions in the preten-
sioner system. For additional information,
see "Supplemental air bag warning light"
(P. 1-62). If the operation of the supplemen-
tal air bag warning light indicates there is a
malfunction, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When selling your vehicle, we request that
you inform the buyer about the pretensioner
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light, dis-
playingin the instrument panel, moni-
tors the circuits for the air bag systems, pre-
tensioner(s) and all related wiring.
When the ignition switch is placed in the ON
position, the supplemental air bag warning
light illuminates for about 7 seconds and
then turns OFF. This means the system is
operational. If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
knee air bag and pretensioner systems need
servicing:
• The supplemental air bag warning light re-
mains on after approximately 7 seconds.
• The supplemental air bag warning light flashes intermittently.
• The supplemental air bag warning light does not come on at all.
Under these conditions, the front air bag, side
air bag, curtain air bag, knee air bag or pre-
tensioner systems may not operate properly.
They must be checked and repaired. It is rec-
ommended that you visit an INFINITI retailer
for this service.
WARNING
If the supplemental air bag warning light is
on, it could mean that the front air bag, side
air bag, curtain air bag, knee air bag and/or
pretensioner systems will not operate in an
accident. To help avoid injury to yourself or
others, have your vehicle checked as soon
as possible. It is recommended that you
visit an INFINITI retailer for this service.
Repair and replacement procedure
The front air bags, side air bags, curtain air
bags, knee air bags and pretensioner(s) are
designed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag warning light remains
illuminated after inflation has occurred.

LRS0100
1-62Safety-Seats, seat belts and supplemental restraint system

WARNING
• Once a front air bag, side air bag, curtain
air bag or knee air bag has inflated, the
air bag module will not function again
and must be replaced. Additionally, the
activated pretensioner(s) must also be
replaced. The air bag module and preten-
sioner(s) should be replaced. It is recom-
mended that you visit an INFINITI re-
tailer for this service. However, the air
bag module and pretensioner(s) cannot
be repaired.
• The front air bag, side air bag, curtain air
bag, knee air bag systems and the pre-
tensioner system should be inspected if
there is any damage to the front end or
side portion of the vehicle. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
• If you need to dispose of a supplemental
air bag or pretensioner systems or scrap
the vehicle, it is recommended that you
visit an INFINITI retailer. Incorrect dis-
posal procedures could cause personal
injury. •
If there is an impact to your vehicle from
any direction, your Occupant Classifica-
tion Sensor (OCS) should be checked to
verify it is still functioning correctly. It is
recommended that you visit an INFINITI
retailer for this service. The OCS should
be checked even if no air bags deploy as a
result of the impact. Failure to verify
proper OCS function may result in an im-
proper air bag deployment resulting in
injury or death. In certain frontal collisions with a pedestrian,
the pop-up engine hood system can help re-
duce impact to the head of a pedestrian. This
system is designed to pop up the rear end of
the hood in certain frontal collisions to pro-
vide specified clearance between the hood
and the engine compartment to reduce im-
pact to a pedestrian.
The pop-up engine hood system activates in
certain frontal collisions with pedestrians or
objects when the vehicle is driven at speeds
between approximately 12 and 37 mph (20
and 60 km/h). While driving, the pop-up en-
gine hood may activate in the event of an
impact collision involving the bottom of the
vehicle or bumper. The system activates
when the collision impact reaches a certain
level even though the collision does not cause
damage to the bumper.
The pop-up engine hood operates only when
the ignition switch is in the ON position.
When the ignition switch is in the ON posi-
tion, the pop-up engine hood warning light
illuminates for about 7 seconds and then
turns off. This indicates that the pop-up
engine hood is operational. For additional
information, see “Warning lights, indicator
lights and audible reminders” (P. 2-9).
