WARNING
●The front air bags ordinarily will not
inflate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat
belts to help reduce the risk or severity
of injury in various kinds of accidents
● The front passenger air bag will not
inflate if the passenger air bag status
light is lit. For additional information,
refer to “Front passenger air bag and
status light” in this section. ●
The seat belts and the front air bags are
most effective when you are sitting well
back and upright in the seat. The front
air bags inflate with great force. Even
with the NISSAN Advanced Air Bag Sys-
tem, if you are unrestrained, leaning
forward, sitting sideways or out of posi-
tion in any way, you are at greater risk of
injury or death in a crash. You may also
receive serious or fatal injuries from the
front air bag if you are up against it
when it inflates. Always sit back against the seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always properly 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
NISSAN 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 an occupant classification sensor
(weight sensor) that turns the front pas-
senger air bag OFF under some condi-
tions. 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.
For additional information, refer to
“Front passenger air bag and status
light” in this section.
● Keep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the front
air bag inflates.

WARNING
To ensure proper operation of the passen-
ger’s NISSAN 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
2.2 lbs (1 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
● Make sure that there is nothing press-
ing against the rear of the seatback,
such as a child restraint installed in the
rear seat or an object stored on the
floor.
● Make sure that there is no object placed
between the seat cushion and center
console or between the seat cushion
and the door. ●
If a forward facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem 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.
For additional information about in-
stalling and using child restraints, refer
to Child restraints in this section.
● 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 as de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.
● Until you have confirmed with a dealer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions.
Safety—Seats, seat belts and supplemental restraint system1-49

●Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status light
may illuminate and the supplemental
air bag warning light may flash.
This vehicle is equipped with the NISSAN Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S. regu-
lations. It is also permitted in Canada. However,
all of the information, cautions and warn-
ings 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 dashboard 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 sys-
tem operation. The NISSAN Advanced Air Bag System monitors
information from the crash zone sensor, the Air
bag Control Unit (ACU) , seat belt buckle sensors
and occupant classification sensor (weight sen-
sor) . Inflator operation 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 un-
belted. Additionally, the front passenger air bag
may be automatically turned off under some con-
ditions, depending on the weight detected on the
front passenger seat and how the seat belt is
used. If the front passenger air bag is OFF, the
front passenger air bag status light will be illumi-
nated. For additional 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 a
NISSAN dealer to obtain information about the
system. If you are considering modification of
your vehicle due to a disability, you may also
contact NISSAN. Contact information is con-
tained 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 do not provide
restraint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the driver and
front 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 front air bag module during infla-
tion.
The front air bags deflate quickly after a collision.
1-50Safety—Seats, seat belts and supplemental restraint system

●Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects 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) .
● 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 seri-
ous personal injury. ●
It is recommended that you visit a
NISSAN dealer for work on and around
the front air bag system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Restraint
System (SRS) wiring harnesses* should
not be modified or disconnected. Unau-
thorized electrical test equipment and
probing devices should not be used on
the air bag system.
● A cracked windshield should be re-
placed immediately by a qualified repair
facility. A cracked windshield could af-
fect the function of the supplemental air
bag system.
*The SRS wiring harness connectors are
yellow 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 appropriate sections
in this Owner’s Manual.
Front 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 seats. The curtain air bags
are located in the side roof rails. All of the
information, cautions 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

1-56Safety—Seats, seat belts and supplemental restraint system

If any of the following conditions occur, the front
air bag, side air bag and curtain 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 and curtain air bag or pretensioner systems
may not operate properly. They must be checked
and repaired. It is recommended that you visit a
NISSAN dealer 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 and/or preten-
sioner systems will not operate in an acci-
dent. To help avoid injury to yourself or
others, have your vehicle checked as soon
as possible. It is recommended that you
visit a NISSAN dealer for this service.
Repair and replacement procedure
The front air bags, side air bags, curtain 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.
These systems should be repaired and/or re-
placed as soon as possible. It is recommended
that you visit a NISSAN dealer for this service.
When maintenance work is required on the ve-
hicle, the front air bags, side air bags, curtain air
bags, pretensioner(s) and related parts should be
pointed out to the person performing the mainte-
nance. The ignition switch should always be
placed in the LOCK position when working under
the hood or inside the vehicle.
WARNING
● Once a front air bag, side air bag, or
curtain air bag has inflated, the air bag
module will not function again and
must be replaced. Additionally, the acti-
vated pretensioner(s) must also be re-
placed. The air bag module and preten-
sioner(s) should be replaced. It is
recommended that you visit a NISSAN
dealer for this service. However, the air
bag module and pretensioner(s) cannot
be repaired. ●
The front air bag, side air bag, curtain
air bag systems and the pretensioner
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 a NISSAN dealer
for this service.
● If you need to dispose of the supple-
mental air bag or pretensioner systems
or scrap the vehicle, it is recommended
that you visit a NISSAN dealer. Incorrect
disposal procedures could cause per-
sonal 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 a NISSAN
dealer 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
improper air bag deployment resulting
in injury or death.
