PRECAUTIONS ON SRS

This SRS section contains important infor-

mation concerning the following systems:

This system can help cushion the impact

force to the head of occupants in the out-

board seating positions in certain side-

impact or rollover collisions. In a side im-

pact, the curtain air bags are designed to

inflate on the side where the vehicle is im-

pacted. In a rollover, curtain air bags are

designed to inflate and remain inflated for

a short time.

WARNING

∙

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 System, if

you are unrestrained, leaning forward,

sitting sideways or out of position 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 in-

flates. Always sit back against the seat-

back and as far away as practical from

the steering wheel or instrument panel.

Always properly use the seat belts.

∙ The front air bags ordinarily will not

inflate in the event of a side impact,

rear impact, rollover, or lower severity

frontal 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 or if the front passenger seat

is unoccupied. For additional infor-

mation, refer to “Front passenger air

bag and status light” in this section.

Safety—Seats, seat belts and supplemental restraint system 1-45

∙ The driver and front passenger seat

belt buckles are equipped with sen-

sors 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 in-

flates the air bags as needed. Failure

to properly wear seat belts can in-

crease the risk or severity of injury in

an accident.

∙ The front passenger seat is equipped

with an occupant classification sen-

sor (weight sensor) that turns 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. For additional informa-

tion, refer to “Front passenger air bag

and status light” in this section.

strained in the rear seat, if possible.

∙ Even with the NISSAN Advanced Air

Bag System, never install

a

rear-

facing child restraint in the front seat.

An inflating front air bag could seri-

ously injure or kill your child. For addi-

tional information, refer to “Child re-

WARNING

∙ 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. For additional in-

formation, refer to “Child restraints” in

this section.

∙ 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 supple-

mental air bag warning light may

flash.

To ensure proper operation of the pas-

senger’s NISSAN Advanced Air Bag Sys-

tem, 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

4 kg (9.1 lbs.) on the seatback, head

restraint/headrest or in the seatback

pocket.

This vehicle is equipped with the NISSAN

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. However, all of the information,

cautions and warnings in this manual

still apply and must be followed.

∙ Confirm the operating condition with

the front passenger air bag status

light.

∙ Make sure that there is nothing press-

ing against the rear of the seatback,

such as a child restraint installed in

damage (or lack of it) is not always an indi-

cation of proper front air bag system op-

eration.

If you have any questions about your air

bag system, it is recommended that you

visit a NISSAN dealer. If you are considering

modification of your vehicle due to a dis-

ability, you may also contact NISSAN. Con-

tact information is contained in the front of

this Owner’s Manual.

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 inflation.

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 classifi-

cation sensor (weight sensor). Inflator op-

eration is based on the severity of a colli-

sion and seat belt usage for the driver. For

the front passenger, the occupant classifi-

cation sensors are also monitored. Based

on information from the sensors, only one

front air bag may inflate in a crash, depend-

ing on the crash severity and whether the

front occupants are belted or unbelted. Ad-

ditionally, the front passenger air bag may

be automatically turned OFF under some

conditions, depending on the weight de-

tected on the front passenger seat and

how the seat belt is used. If the front pas-

senger air bag is OFF, the front passenger

air bag status light will be illuminated (if the

seat is unoccupied, the light will not be illu-

minated, but the air bag will be off). For

additional information, refer to “Front pas-

senger air bag and status light” in this sec-

tion. One front air bag inflating does not

indicate improper performance of the sys-

tem.

The front air bags deflate quickly after a

collision.

When a front air bag inflates, a fairly loud

noise may be heard, followed by the re-

lease 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 irrita-

tion and choking. Those with a history of a

breathing condition should get fresh air

promptly.

The front air bags operate only when the

ignition switch is placed in the ON posi-

tion.

After 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

after about 7 seconds if the system is

operational.

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 seri-

ous injuries. However, an inflating front air

bag may cause facial abrasions or other

injuries. Front air bags do not provide re-

straint to the lower body.

Even with NISSAN 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 in-

flate quickly in order to help protect the

operated under some conditions as de-

scribed below in accordance with U.S. regu-

lations. If the front passenger air bag is OFF,

it will not inflate in a crash. The driver air bag

and other air bags in your vehicle are not

part of this system.

Unoccupied front passenger’s seat:

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 protec-

tion. 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.

ing the air bag to be automatically turned

OFF. Certain sensors are used to meet the

requirements.

NISSAN recommends that pre-teens and

children be properly restrained in a rear

seat. NISSAN also recommends that ap-

propriate child restraints and booster

seats be properly installed in a rear seat. If

this is not possible, the occupant classifica-

tion sensor is designed to operate as de-

scribed above to turn the front passenger

air bag OFF for specified child restraints as

required by the regulations. Failing to prop-

erly secure child restraints and to use the

ALR mode may allow the restraint to tip or

move in a collision or sudden stop. This can

also result in the passenger air bag inflat-

ing in a crash instead of being OFF. For

additional information, refer to “Child re-

straints” in this section.

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.

The occupant classification sensor in this

vehicle is a weight sensor. It is designed to

detect an occupant and objects on the

seat by weight. For example, if a child is in

the front passenger seat, the NISSAN Ad-

vanced Air Bag System is designed to turn

the front passenger air bag OFF in accor-

dance with the regulations. Also, if a child

restraint of the type specified in the regula-

tions is on the seat, its weight and the

child’s weight can be detected and cause

the air bag to turn OFF.

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, de-

pending on the size of the child and the

type of child restraint being used. If the air

bag status light is not illuminated (indicat-

ing 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 properly and the occu-

pant is positioned properly. If the air bag

status light is still not illuminated, reposi-

tion the occupant or child restraint in a rear

seat.

Front passenger seat adult occupants who

are properly seated and using the seat belt

as outlined in this manual should not

cause the front passenger air bag to be

automatically turned OFF. For small adults

it may be turned OFF, however if the occu-

pant takes his/her weight off the seat

cushion (for example, by not sitting upright,

by sitting on an edge of the seat, or by

otherwise being out of position), this could

cause the sensor to turn the air bag OFF.

Always be sure to be seated and wearing

the seat belt properly for the most effective

protection by the seat belt and supple-

mental air bag.

If the front passenger seat is not occupied,

the front passenger air bag is designed not

to inflate in a crash. However, heavy objects

placed on the seat could result in air bag

inflation, because of the object’s weight de-

tected by the occupant classification sen-

sor. Other conditions could also result in air

bag inflation, such as if a child is standing

on the seat, or if two children are on the

seat, contrary to the instructions in this

manual. Always be sure that you and all

vehicle occupants are seated and re-

strained properly.

Safety—Seats, seat belts and supplemental restraint system 1-55

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.

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 bags

and curtain air bags 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 after the collision is over.

Curtain air bags are also designed to inflate

in certain types of rollover collisions or near

rollovers. As a result, certain vehicle move-

ments (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.

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

inflate if the forces in another type of colli-

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.

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.

Side air bags, along with the use of seat

belts, help to cushion the impact force on

the chest of the front occupants. Curtain

air bags help to cushion the impact force to

the head of occupants in the front and rear

outboard seating positions. They can help

save lives and reduce serious injuries. How-

After 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

after about 7 seconds if the system is

operational.

WARNING

∙ Tampering with the side air bag sys-

tem may result in serious personal in-

jury. For example, do not change the

front seats by placing material near

the seatbacks or by installing addi-

tional trim material, such as seat cov-

ers, around the side air bag.

∙ 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.

WARNING

∙ The pretensioner(s) cannot be reused

after activation. They must be re-

placed together with the retractor

and buckle as a unit.

∙ It is recommended that you visit a

NISSAN dealer for work around and on

the side air bag and curtain air bag

system. 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.

∙ 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.

∙ Right after 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.

∙ No unauthorized changes should be

made to any components or wiring of

the pretensioner system. This is to

prevent damage to or accidental acti-

vation of the pretensioner(s). Tamper-

ing with the pretensioner system may

result in serious personal injury.

* The SRS wiring harness or connectors

are yellow or orange for easy identifica-

tion.

∙ 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.

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.

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.

After the pretensioner(s’) activation, load

limiters allow the seat belt to release web-

bing (if necessary) to reduce forces against

the chest.

∙ 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 preten-

sioner 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 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 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.

1. SRS Air bag warning labels

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 warning labels are located on the

surface of the sun visors.

Repair and replacement

procedure

WARNING

∙ If there is an impact to your vehicle

from any direction, your Occupant

Classification 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 im-

pact. Failure to verify proper OCS

function may result in an improper air

bag deployment resulting in injury or

death.

∙ 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 activated pretensioner(s) must

also be replaced. The air bag module

and pretensioner(s) should be re-

placed. It is recommended that you

visit a NISSAN dealer for this service.

However, the air bag module and pre-

tensioner(s) cannot be repaired.

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 re-

minder, unless it is damaged, the supple-

mental air bag warning light remains illu-

minated after inflation has occurred. These

systems should be repaired and/or re-

placed as soon as possible. It is recom-

mended that you visit a NISSAN dealer for

this service.

∙ 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.

When maintenance work is required on the

vehicle, the front air bags, side air bags,

curtain air bags, pretensioner(s) and re-

lated parts should be pointed out to the

person performing the maintenance. The

ignition switch should always be placed in

the LOCK position when working under the

hood or inside the vehicle.

∙ If you need to dispose of the supple-

mental air bag or pretensioner sys-

tems or scrap the vehicle, it is recom-

mended that you visit

a

NISSAN

dealer. Incorrect disposal procedures

could cause personal injury.
