SUPPLEMENTAL RESTRAINT SYSTEM

(SRS)

signed to inflate on the side where the ve-

hicle is impacted.

The SRS is designed to supplement the

crash protection provided by the driver,

passenger and rear outboard seat belts

and is not a substitute for them. Seat belts

should always be correctly worn, and the

occupant should be seated a suitable dis-

tance away from the steering wheel, instru-

ment panel and door finishers. For addi-

tional information, refer to “Seat belts” in

this section.

PRECAUTIONS ON SRS

This SRS section contains important infor-

mation concerning the following systems.

Rear outboard seat-mounted side-

impact supplemental air bag system

• Driver and front passenger supplemental

front-impact air bag (NISSAN Advanced

Air Bag System)

This system can help cushion the impact

force to the chest area of the rear outboard

seat passengers in certain side impact col-

lisions. The side air bags are designed to

inflate on the side where the vehicle is im-

pacted.

• Front seat-mounted side-impact supple-

mental air bag

• Rear outboard seat-mounted side-

impact supplemental air bag

The supplemental air bags operate only

when the power switch is in the ON posi-

tion.

• Roof-mounted curtain side-impact and

rollover supplemental air bag

Roof-mounted curtain side-impact and

rollover supplemental air bag system

• Driver and passenger supplemental knee

air bag

This system can help cushion the impact

force to the head of occupants in front and

rear outboard seating positions in certain

side impact collisions. In a side impact, the

curtain air bags are designed to inflate on

the side where the vehicle is impacted. In a

rollover, the curtain air bags are designed

to inflate and remain inflated for a short

time.

After the power switch is placed 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

•

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 and pas-

senger knee air bag will not inflate if

the passenger air bag status light is

lit. For additional information, refer

to “Front passenger air bag and sta-

tus light” in this section.

1-44 Safety–Seats, seat belts and supplemental restraint system

•

The seat belts and the front air bags

are most effective when you are sit-

ting well back and upright in the seat

with both feet on the floor. The front

air bags inflate with great force. Even

with the NISSAN Advanced Air Bag

System, if you are unrestrained, lean-

ing 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 inju-

ries 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 practical from the steering

wheel or instrument panel. Always

properly use the seat belts.

•

The front passenger seat is equipped

with occupant classification sensor

(weight sensor) that turns the front

passenger air bag and passenger

knee 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 in-

crease 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.

•

Keep hands on the outside of the

steering wheel. Placing them inside

the steering wheel rim could increase

the risk that they are injured if the

front air bag inflates.

SSS0007

•

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

inflates the air bags as needed. Fail-

ure to properly wear seat belts can

increase the risk or severity of injury

in an accident.

WARNING

•

Never let children ride unrestrained

or extend their hands or face out of

the window. Do not attempt to hold

them in your lap or arms. Some ex-

amples of dangerous riding posi-

tions are shown in the illustrations.

Children may be severely injured or

killed when the front air bags, side air

bags or curtain air bags inflate if they

are not properly restrained. Pre-

teens and children should be prop-

erly restrained in the rear seat, if

possible.

SSS0008

SSS0099

•

Even with the NISSAN Advanced Air

Bag System, never install a rear-

facing child restraint on the front

seat. An inflating front air bag could

seriously injure or kill your child. For

additional information, refer to “Child

restraints” in this section.

•

When sitting in the rear seat, do not

hold onto the seatback of the front

seat. If the side air bag inflates, you

may be seriously injured. Be espe-

cially careful with children, who

should always be properly re-

strained. Some examples of danger-

ous riding positions are shown in the

illustrations.

WARNING

Front and rear outboard seat-mounted

side-impact supplemental air bags and

roof-mounted curtain side-impact and

rollover supplemental air bags:

•

The side air bags and curtain air bags

ordinarily will not inflate in the event

of a frontal impact, rear impact, or

lower severity side collision. Always

wear your seat belts to help reduce

the risk or severity of injury in various

kinds of accidents.

•

Do not use seat covers on the front

and rear seatbacks. They may inter-

fere with side air bag inflation.

•

The seat belts, the side air bags and

curtain air bags are most effective

when you are sitting well back and

upright in the seat. The side air bag

and curtain air bag inflate with great

force. Do not allow anyone to place

their hand, leg or face near the side

air bag on the side of the seatback of

the front and rear seat or near the

side roof rails. Do not allow anyone

sitting in the front seats or rear out-

board seats to extend their hand out

of the window or lean against the

door. Some examples of dangerous

riding positions are shown in the pre-

vious illustrations.

WARNING

To ensure proper operation of the front

passenger’s NISSAN Advanced Air Bag

System, please observe the following

items.

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. All of the information, cautions

and warnings in this manual apply and

must be followed.

•

Do not allow a passenger in the rear

seat to push or pull on the seatback

pocket (if so equipped).

•

Do not place heavy loads heavier

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

head restraint/headrest or in the

seatback pocket (if so equipped).

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 in-

strument 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. Ve-

1-50 Safety–Seats, seat belts and supplemental restraint system

The NISSAN Advanced Air Bag System

monitors information from the crash zone

sensor and the Air bag Control Unit (ACU).

Inflator operation is based on the severity

of a collision and seat belt usage for the

driver. For the front passenger, the occu-

pant classification sensor is also moni-

tored. Based on information from the sen-

sor, only one front air bag may inflate in a

crash, depending on the crash severity. Ad-

ditionally, the front passenger air bag and

passenger knee air bag may be automati-

cally turned OFF under some conditions,

depending on the weight detected on the

passenger seat and how the seat belt is

used. If the front passenger air bag and

passenger knee air bag are OFF, the pas-

senger 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 improper performance of the

system.

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 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

power switch is in the ON position.

After the power switch is placed 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 head 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, other than the driv-

er’s knee air bag, 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 in-

crease the risk of injury if the occupant is

too close to, or is against, the air bag mod-

ule during inflation.

If you have any questions about your air

bag system, it is recommended that you

visit a NISSAN certified LEAF dealer to ob-

tain information about the system. If you

are considering modification of your ve-

hicle due to a disability, you may also con-

tact NISSAN. Contact information is con-

tained in the front of this Owner’s Manual.

The front air bags deflate quickly after a

collision.

WARNING

The front passenger seat is equipped with

an occupant classification sensor (weight

sensor) that turns the front passenger air

bag and passenger knee air bag on or off

depending on the weight applied to the

front passenger seat. The status of the

front passenger air bag and passenger

knee air bag (ON or OFF) is indicated by the

front passenger air bag status light

The front passenger air bag and pas-

senger knee air bag are designed to au-

tomatically turn OFF under some con-

ditions. 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 in-

jury in an accident.

allow the restraint to tip or move in a colli-

sion or sudden stop. This can also result in

the front passenger air bag and passenger

knee air bag inflating in a crash instead of

being OFF. For additional information, refer

to “Child restraints” in this section.

The front passenger air bag and passen-

ger knee air bag are designed to automati-

cally turn OFF when the vehicle is operated

under some conditions as described be-

low in accordance with U.S. regulations. If

the front passenger air bag and passenger

knee air bag are 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.

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 and pas-

senger knee air bag to be automatically

turned OFF. For small adults it may be

turned OFF, however if the occupant takes

his/her weight off the seat cushion (for ex-

ample, by not sitting upright, by sitting on

an edge of the seat, or by otherwise being

out of position), this could cause the sen-

sors to turn the front passenger air bag

and passenger knee 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 supplemental air bag.

If the front passenger seat is not occupied,

the front passenger air bag and passenger

knee air bag are 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 being 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.

The purpose of the regulation is to help

reduce the risk of injury or death from an

inflating air bag to certain front passenger

seat occupants, such as children, by requir-

ing the front passenger air bag and pas-

senger knee air bag to be automatically

turned OFF. Certain sensors are used to

meet the requirements.

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 and passenger

knee air bag OFF in accordance with the

regulations. Also, if a child restraint of the

type specified in the regulations is on the

seat, its weight and the child’s weight can

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 and passenger knee air bag OFF for

specified child restraints as required by

regulations. Failing to properly secure child

Using the front passenger air bag status

light, you can monitor when the front pas-

your air bag is working properly, reposition

the occupant or child restraint in a rear

seat.

• Make sure that a child restraint or other

object is not pressing against the rear of

the seatback.

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

front passenger air bag status light is not

illuminated (indicating that the front pas-

senger air bag and passenger knee 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 occupant is positioned

properly. If the front passenger air bag sta-

tus light is still not illuminated, reposition

the occupant or child restraint in a rear

seat.

• Make sure that the rear passenger is not

pushing or pulling on the back of the front

passenger 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 front passenger seat status. This is nor-

mal system operation and does not indi-

cate a malfunction.

• Make sure that the front passenger seat

or seatback is not forced back against an

object on the seat or floor behind it.

• Make sure that there is no object placed

under the front passenger seat.

If a malfunction occurs in the front passen-

ger air bag system, the supplemental air

bag warning light

, located in the me-

Steps

ter and gauges area of the instrument

panel, will be illuminated (blinking or

steadily lit). Have the system checked. It is

recommended that you visit a NISSAN cer-

tified LEAF dealer for this service.

1. Adjust the seat as outlined in the “Seats”

section of this manual. Sit upright, lean-

ing against the seatback, and centered

on the seat cushion with your feet com-

fortably extended to the floor.

2. Make sure there are no objects on your

lap.

In order for the occupant classification

sensor system to classify the front passen-

ger based on weight, please follow the pre-

cautions and steps outlined below:

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, it is

recommended that you take your vehicle

to a NISSAN certified LEAF dealer. A NISSAN

certified LEAF dealer can check system

status by using a special tool. However, un-

til you have confirmed with a dealer that

3. Fasten the seat belt as outlined in the

“Seat belts” section of this manual. Front

passenger seat belt buckle status is

monitored by the occupant classifica-

tion system, and is used as an input to

determine occupancy status. So, it is

highly recommended that the front pas-

senger fasten their seat belt.

Precautions

• Make sure that there are no objects

weighing over 9.1 lbs. (4 kg) hanging on

the seat or placed in the seatback pocket

(if so equipped).

1-54 Safety–Seats, seat belts and supplemental restraint system

4. Remain in this position for 30 seconds

allowing the system to classify the front

passenger before the vehicle is put into

motion.

However, if the occupant is not a small

adult, then this may be due to the following

conditions that may be interfering with the

weight sensors:

NOTE:

A system check will be performed during

which the front passenger air bag status

light will remain lit for about 7 seconds

initially.

• Occupant is not sitting upright, lean-

ing against the seatback, and cen-

tered on the seat cushion with his/her

feet comfortably extended to the floor.

5. Ensure proper classification by checking

the front passenger air bag status light.

If the light is still ON after this, the person

should be advised not to ride in the front

passenger seat and the vehicle should be

checked as soon as possible. It is recom-

mended that you visit a NISSAN certified

LEAF dealer for this service.

NOTE:

• A child restraint or other object press-

ing against the rear of the seatback.

This vehicle’s occupant classification

sensor system generally keeps the clas-

sification locked during driving, so it is

important that you confirm that the

front passenger is properly classified

prior to driving. However, the occupant

classification sensor may recalculate the

weight of the occupant under some con-

ditions (both while driving and when

stopped), so front passenger seat occu-

pants should continue to remain seated

as outlined above.

• A rear passenger pushing or pulling on

the back of the front passenger seat.

2. If the light is OFF with a small adult, child

or child restraint occupying the front

passenger seat.

• Forcing the front seat or seatback

against an object on the seat or floor

behind it.

This may be due to the following condi-

tions that may be interfering with the

weight sensors:

• An object placed under the front pas-

senger seat.

• An object placed between the seat

cushion and center console or be-

tween the seat cushion and the door.

• Small adult or child is not sitting up-

right, leaning against the seatback,

and centered on the seat cushion with

his/her feet comfortably extended to

the floor.

Troubleshooting

If the vehicle is moving, please come to a

stop when it is safe to do so. Check and

correct any of the above conditions. Re-

start the vehicle and wait 1 minute.

If you think the front passenger air bag

status light is incorrect:

• The child restraint is not properly in-

stalled, as outlined in the “Child re-

straints” section of this manual.

1. If the light is ON with an adult occupying

the front passenger seat:

• Occupant is a small adult — the air bag

light is functioning as intended. The

front passenger air bag and passen-

ger knee air bag are suppressed.

• An object weighting over 9.1 lbs. (4 kg)

hanging on the seat or placed in the

seatback pocket (if so equipped).

NOTE:

•

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.

•

Do not place objects with sharp

edges on the seat. Also, do not place

heavy objects on the seat that will

leave permanent impressions in the

seat. Such objects can damage the

seat or occupant classification sen-

sor (weight sensor). This can affect

the operation of the air bag system

and result in serious personal injury.

A system check will be performed during

which the front passenger air bag status

light will remain lit for about 7 seconds

initially.

If the light is still OFF after this, the small

adult, child or child restraint should be re-

positioned in the rear seat and the vehicle

should be checked as soon as possible. It is

head of occupants in the front and rear

outboard seating positions. They can help

save lives and reduce serious injuries. How-

ever, side air bags and curtain air bags may

cause abrasions or other injuries. Side air

bags and curtain air bags do not provide

restraint to the lower body.

If so equipped, the curtain air bags are also

designed to inflate in certain types of roll-

over collisions or near rollovers. As a result,

certain vehicle movements (for example,

during severe off-roading) may cause the

curtain air bags to inflate.

The seat belts should be correctly worn

and the driver, front passenger and rear

outboard occupants seated upright as far

as practical away from the side air bags.

Rear seat passengers should be seated as

far away as practical from the door finish-

ers and side roof rails. The side air bags and

curtain air bags inflate quickly in order to

help protect the occupants in the outboard

seating positions. Because 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 during inflation. The side

air bags and curtain air bags will deflate

quickly after the collision is over.

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.

The side air bags are located in the outside

of the seatback of the front seats and rear

The knee air bag helps to cushion the im-

pact force on the knees of the driver and

passenger. It can help reduce serious inju-

ries. However, an inflating knee air bag may

cause abrasions or other injuries. The knee

air bag provides restraint to the lower body.
