seat, contrary to the instructions in this
manual. Always be sure that you and all
vehicle occupants are seated and re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag is automatically turned OFF
with the seat occupied. The light will not
illuminate when the front passenger seat is
unoccupied.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (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 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 occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). A
NISSAN dealer can check that the system is
OFF by using a special tool. However, until
you have confirmed with a dealer that your
air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the passenger seat status. For example, if a
large adult who is sitting in the front pas-
senger seat exits the vehicle, the front pas-
senger air bag status light will go from OFF
to ON for a few seconds and then to OFF.
This is normal system operation and does
not indicate a malfunction.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will blink. Have the system checked. It
is recommended that you visit a NISSAN
dealer for this service. Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment 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 in-
jury if the front air bags inflate.
• Immediately af ter 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 dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.
Safety-Seats, seat belts and supplemental restraint system1-81

•Tampering with the front air bag sys-
tem may result in serious personal
injury. Tampering includes changes
to the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad
and above the instrument panel or
by installing additional trim material
around the air bag system.
• Modif ying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that are not specifically designed to
assure proper air bag operation. Ad-
ditionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (pressure sensor).
• No unauthorized changes should be
made to any components or wiring
of the seat belt system. This may af-
fect the front air bag system. Tam-
pering with the seat belt system may
result in serious personal injury. •
It is recommended that you visit a
NISSAN dealer for work on and
around the front air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices should not be used on the air
bag system.
• A cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
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 cur-
tain air bags are located in the side roof
rails. All of the information, cautions and
warnings in this manual apply and must
be followed. The side air bags and curtain
air bags are designed to inflate in higher
severity side collisions, although they may
LRS2501
1-82Safety-Seats, seat belts and supplemental restraint system

inflate if the forces in another type of colli-
sion 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,
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.
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 occu-
pants. Curtain air bags help to cushion the
impact force to the head of occupants in
the front and rear outboard seating posi-
tions. They can help save lives and reduce
serious injuries. However, an inflating sideair bag or curtain air bag may cause abra-
sions 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 up-
right 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 occupants. Be-
cause 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 dur-
ing inflation. The side air bag will deflate
quickly af ter the collision is over.
The curtain air bags will remain inflated for
a short time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON or START position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
• Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door fin-
isher and the front seat. Such objects
may become dangerous projectiles
and cause injury if a side air bag
inflates.
• Right af ter inflation, several side air
bag and curtain air bag system com-
ponents 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 systems.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or side panel.
This could affect proper operation of
the curtain air bag systems.
Safety-Seats, seat belts and supplemental restraint system1-83

•Tampering with the side air bag sys-
tem may result in serious personal
injury. For example, do not change
the front 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 a
NISSAN dealer for work on and
around the side air bag and curtain
air bag. It is also recommended that
you visit a NISSAN dealer for installa-
tion of electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Unauthor-
ized electrical test equipment and
probing devices should not be used
on the side air bag or curtain air bag
systems.
* The SRS wiring harness or connectors
are yellow or orange for easy identifica-
tion.
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 re-
used af ter 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
activated, 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
prevent damage to or accidental ac-
tivation of the pretensioner(s). Tam-
pering with the pretensioner system
may result in serious personal injury. •
It is recommended that you visit a
NISSAN dealer for work on and
around the pretensioner system. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. Unauthorized elec-
trical 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 per-
sonal 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 be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt an-
chor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts.
1-84Safety-Seats, seat belts and supplemental restraint system

When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. For additional infor-
mation, refer to "Supplemental air bag
warning light" in this section. If the opera-
tion 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 ser-
vice.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner's
Manual.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
• If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if
the vehicle is parked. Some recre-
ational vehicle appliances such as
stoves, refrigerators, heaters, etc.
may also generate carbon monoxide.
