PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be worn
snug, and always position the lap belt as low
as possible around the hips, not the waist,
and place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific re-
commendations.
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts, depending on the injury.
Check with your doctor for specific recom-
mendations.
PRE-CRASH SEAT BELTS WITH
COMFORT FUNCTION (if so
equipped for front seats)
The pre-crash seat belt tightens the seat belt
with a motor to help restrain front seat
occupants. This helps reduce the risk of
injury in a collision.
The motor retracts the seat belt under the
following emergency conditions:
.During emergency braking
. During sudden steering maneuvers
. Activation of the Forward Emergency
Braking (FEB) with pedestrian detection system. (See “Forward Emergency Brak-
ing (FEB) with pedestrian detection”
(P.5-95).)
. In the event of a high severity rollover
collision.
The pre-crash seat belt will not be active
when:
. the seat belt is not fastened
. the vehicle speed is under 10 MPH (15
km/h) during emergency braking
. the vehicle speed is under 19 MPH (30
km/h) during sudden steering maneuvers
or in the event of a high severity rollover
collision.
The pre-crash seat belt will not be active
when the brake pedal is not depressed
except when sudden steering maneuvers
occur or the Forward Emergency Braking
(FEB) with pedestrian detection system
activates.
The motor also retracts the seat belt when
the seat belt is fastened or unfastened.
When the seat belt is fastened, the motor
tightens the seat belt for a snug fit. When
the seat belt is unfastened, the motor
retracts the seat belt. If the seat belt is not
fully retracted, the motor retracts the seat
belt when the door is opened.
Always wear your seat belt correctly and sit
upright and well back. If the motor cannot retract the seat belt
when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat belt
system has a malfunction. Have the system
checked and repaired. It is recommended you
visit an INFINITI retailer for this service.
When the seat belt is retracted repeatedly in
a short period of time, the motor may not be
able to retract the seat belt. After 8 minutes,
the motor reactivates and retracts the seat
belt. If the seat belt still cannot be retracted
by the motor, the pre-crash seat belt system
has a malfunction. Have the system checked
and repaired. It is recommended you visit an
INFINITI retailer for this service.
THREE-POINT TYPE SEAT BELT
WARNING
.
Every person who drives or rides in
this vehicle should use a seat belt at
all times.
. Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
Safety — seats, seat belts and supplemental restraint system1-21

seat belts.
. The driver and front passenger seat
belt buckles are equipped with sen-
sors 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. Failure to prop-
erly wear seat belts can increase the
risk or severity of injury in an acci-
dent.
. The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. This sensor is 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.1-60).
. 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.

flash.
. 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.

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
