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
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, sus-
pension 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 instrument 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
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. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equipment.
The Supplemental Restraint System
(SRS) wiring harnesses* should not be
modified or disconnected. Unauthor-
ized electrical test equipment and prob-
ing 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.
1-54Safety—Seats, seat belts and supplemental restraint system

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 are designed to inflate on the side where the
vehicle is impacted. They may not inflate in cer-
tain 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, 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 con-
dition 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 occupants. Curtain air
bags help to cushion the impact force to the head
of occupants in the front and rear outboard seat-
ing positions. They can help save lives and re-
duce 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 and passenger seated upright as far as
practical away from the side air bag. Rear seat
passengers should be seated as far away as
practical from the door finishers and side roof
rails. The side air bags and curtain air bags inflate
quickly in order to help protect the front and rear
outboard 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 inflation. The side air bag and 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 op-
erate 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.

Safety—Seats, seat belts and supplemental restraint system1-55

WARNING
●Do not place any objects near the seat-
back of the front seats. Also, do not
place any objects (an umbrella, bag,
etc.) between the front door finisher
and the front seat. Such objects may
become dangerous projectiles and
cause injury if a side air bag inflates.
● 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
accidental inflation of the side air bag
and curtain 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, sus-
pension system or side panel. This
could affect 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
seats by placing material near the seat-
backs or by installing additional trim
material, such as seat covers, around
the side air bag.
● It is recommended that you visit a
NISSAN dealer for work on and around
the side air bag and curtain air bag
systems. It is also recommended that
you visit a NISSAN dealer for installa-
tion of electrical equipment. The SRS
wiring harnesses* should not be modi-
fied or disconnected. Unauthorized
electrical test equipment and probing
devices should not be used on the side
air bag or curtain air bag systems.
*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 side air bag and
curtain air bag systems and guide the buyer to
the appropriate sections in this Owner’s Manual.
Seat belt with pretensioner(s) (front
seats)
WARNING
● The pretensioner(s) cannot be reused
after activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
collision but pretensioner(s) are not ac-
tivated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit a NISSAN dealer for this
service.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioner(s) . Tampering with
the pretensioner system may result in
serious personal injury.
1-56Safety—Seats, seat belts and supplemental restraint system

●It is recommended that you visit a
NISSAN dealer for work on and around
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
● If you need to dispose of the preten-
sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause personal
injury.
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 involved in certain
types of collisions, helping to restrain front 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 limiters
allow the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
The supplemental air bag warning light
is
used to indicate malfunctions in the pretensioner
system. For additional information, refer to
Supplemental air bag warning light in this sec-
tion. If the operation of the supplemental air bag
warning light indicates there is a malfunction,
have the system checked. It is recommended that
you visit a NISSAN dealer for this service.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual. 1. SRS Air bag warning labels
The warning labels are located on the sur-
face of the sun visor.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel, moni-
tors the circuits for the air bag systems, preten-
sioner(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 and preten-
sioner 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 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

NOTE:
In the event of a crash involving an air bag
deployment (side, front or both) , the vehi-
cle’s hazard lamps (turn indicators) will
turn ON automatically.
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

● 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.
