Nissan Altima (2024 year). Manual in english

WARNING

•

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
additional information, see “Child re-
straints” (P. 1-22).

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.

WARNING

•

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 with both feet on
the floor. 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 outboard seats to
extend their hand out of the window
or lean against the door. Some ex-
amples of dangerous riding positions
are shown in the previous illustrations.

WARNING

•

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 especially
careful with children, who should al-
ways be properly restrained. Some ex-
amples of dangerous riding positions
are shown in the illustrations.

•

Do not use seat covers on the front or
rear seatbacks. They may interfere
with side air bag inflation.

WARNING

To ensure proper operation of the
passenger’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 9.1 lbs. (4 kg) on the seatback,
head restraint/headrest or in the
seatback pocket.

•

Make sure that there is nothing
pressing against the rear of the seat-
back, such as a child restraint in-
stalled in the rear seat or an object
stored on the floor.

•

Make sure that there is no object
placed under the front passenger seat.

•

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
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts
the instrument panel. If the child re-
straint does contact the instrument
panel, the system may determine the
seat is occupied and the passenger
air bag and front passenger supple-
mental knee 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,
see "Child restraints" (P. 1-22).

•

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 described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service.

•

Until you have confirmed with a dealer
that your passenger seat occupant
classification system is working prop-
erly, position the occupants in the rear
seating positions.

•

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
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.

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 dash-
board 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 fron-
tal collisions. Vehicle damage (or lack of it) is
not always an indication of proper front air
bag system operation.

Safety-Seats, seat belts and supplemental restraint system

1-53

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 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 unbelted. Addi-
tionally, the front passenger air bag and
front passenger supplemental knee air
bag may be automatically turned off under
some conditions, depending on the weight
detected on the front passenger seat and
how the seat belt is used. If the front pas-
senger

air

bag

and

front

passenger

supplemental knee air bag are OFF, the
front passenger air bag status light will be
illuminated. For additional information,
see “Front passenger air bag and status
light” (P. 1-55). One front air bag inflating
does not indicate improper 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 dis-
ability, you may also contact NISSAN. Con-
tact information is contained in the front of
this Owner's Manual.

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.

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 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 front air bag
module during inflation.

The front air bags deflate quickly after a
collision.

The front air bags operate 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 supple-
mental air bag warning light will turn off
after about 7 seconds if the system is
operational.

Front passenger air bag and status
light

WARNING

The front passenger air bag and front
passenger supplemental knee air bag
are designed to automatically turn OFF
under some conditions. Read this sec-
tion carefully to learn how it operates.
Proper use of the seat, seat belt, and
child restraints is necessary for most
effective protection. Failure to follow all
instructions in this manual concerning
the use of seats, seat belts, and child
restraints can increase the risk or se-
verity of injury in an accident.

Status light

The front passenger seat is equipped with
an occupant classification sensor (weight
sensor) that turns the front passenger air
bag and front passenger supplemental
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 front passengers supplemental knee
air bag (ON or OFF) is indicated by the front
passenger air bag status light

which

is located on the instrument panel.

After the ignition switch is placed in the
"ON" position, the front passenger air bag
status light on the instrument panel illumi-
nates for about 7 seconds and then turns
off or remains illuminated depending on
the front passenger seat occupied status.
The light operates as follows:

Front passenger air bag

The front passenger air bag and front pas-
senger supplemental knee air bag is de-
signed to automatically turn OFF when the
vehicle is operated under some conditions
as described below in accordance with U.S.
regulations. If the front passenger air bag
and front passenger supplemental knee
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.

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 air bags 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 front pas-
senger supplemental 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 be detected and
cause the air bag to turn OFF.

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
front passenger supplemental 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 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 bags
OFF. Always be sure to be seated and wear-
ing the seat belt properly for the most ef-
fective protection by the seat belt and
supplemental air bag.

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 classifi-
cation sensor is designed to operate as
described above to turn the front passen-
ger air bag and front passenger supple-
mental knee air bag OFF for specified child
restraints as required by the regulations.
Failing to properly 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 and front passenger
supplemental knee air bag inflating in a
crash instead of being OFF. For additional
information about proper use and installa-
tion, see “Child restraints” (P. 1-22).

If the front passenger seat is not occupied,
the front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed 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 detected by the occupant
classification sensor. Other conditions could
also result in air bag inflation, such as if a
child is standing on the seat, or if two chil-
dren are on the seat, contrary to the instruc-
tions in this manual. Always be sure that you
and all vehicle occupants are seated and
restrained properly.

Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag and front passenger supple-
mental knee air bag are automatically
turned OFF.

1-56

Safety-Seats, seat belts and supplemental restraint system

If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the front passen-
ger air bag and front passenger supple-
mental knee air bag are 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.

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 dealer. A NISSAN dealer can
check system status 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 front passenger seat status. This is nor-
mal system operation and does not indi-
cate 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 be illuminated (blinking or
steadily lit). Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.

Normal operation

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:

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.

• Make sure that a child restraint or other

object is not pressing against the rear of
the seatback.

• Make sure that a rear passenger is not

pushing or pulling on the back of the front
passenger seat.

• 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.

Steps

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

(P. 1-2) section of this manual. Sit upright,
leaning against the seatback, and cen-
tered on the seat cushion with your feet
comfortably extended to the floor.

2. Make sure there are no objects on your

lap.

3. Fasten the seat belt as outlined in the

“Seat belts” (P. 1-12) section of this
manual. Front passenger seat belt
buckle status is monitored by the occu-
pant classification system, and is used
as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fasten their seat
belt.

Safety-Seats, seat belts and supplemental restraint system

1-57

4. Remain in this position for 30 seconds

allowing the system to classify the front
passenger before the vehicle is put into
motion.

5. Ensure proper classification by checking

the front passenger air bag status light.

NOTE:

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.

Troubleshooting

If you think the front passenger air bag
status light is incorrect:

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 pas-
senger air bag and front passenger supple-
mental knee air bag are suppressed.

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:
• Occupant is not sitting upright, leaning

against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.

• A child restraint or other object pressing

against the rear of the seatback.

• A rear passenger pushing or pulling on

the back of the front passenger seat.

• Forcing the front seat or seatback against

an object on the seat or floor behind it.

• An object placed under the front passen-

ger seat.

• An object placed between the seat cush-

ion and center console or between the
seat cushion and the door.

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.

NOTE:

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 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 dealer for
this service.

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

or child restraint occupying the front
passenger seat.

This may be due to the following condi-
tions that may be interfering with the
weight sensors:

• Small adult or child is not sitting upright,

leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.

• The child restraint is not properly in-

stalled, as outlined in the “Child restraints”
section of this manual.

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

hanging on the seat or placed in the seat-
back pocket.

• A child restraint or other object pressing

against the rear of the seatback.

• A rear passenger pushing or pulling on

the back of the front passenger seat.

• Forcing the front seat or seatback against

an object on the seat or floor behind it.

1-58

Safety-Seats, seat belts and supplemental restraint system

• An object placed under the front passen-

ger seat.

• An object placed between the seat cush-

ion and center console.

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.

NOTE:

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
recommended that you visit a NISSAN
dealer for this service.

3. If the light is OFF with no front passenger

and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.

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 after 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.

•

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.

•

Removing or modifying the front
passenger seat may affect the func-
tion 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 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 (weight sensor).

Safety-Seats, seat belts and supplemental restraint system

1-59

•

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 system. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The Supplemental
Restraint 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
repair 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 identification.

When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.

Front and rear outboard
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 and rear out-
board seats. The curtain air bags are lo-
cated in the side roof rails.

All of the infor-

mation, 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, al-

though they may inflate if the forces in an-
other type of collision are similar to those of
a higher severity impact. They are de-
signed to inflate on the side where the ve-
hicle 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
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.

When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by the release of smoke. 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.

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 and
rear outboard occupants. Curtain air bags
help to cushion the impact force to the
head of occupants in the front and rear

LRS3142

1-60

Safety-Seats, seat belts and supplemental restraint system

outboard seating positions. They can help
save lives and reduce serious injuries. How-
ever, 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, front passenger and rear
outboard occupants 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 finish-
ers and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the 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 in-
flation. The side air bag 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
operate only when the ignition switch is
placed in the ON position.

WARNING

•

Do not place any objects near the
seatback of the front and rear seats.
Also, do not place any objects (an
umbrella, bag, etc.) between the front
and rear door finisher and the front
and rear seat. Such objects may be-
come

dangerous

projectiles

and

cause injury if a side air bag inflate.

•

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 or dam-
age to 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 side air bag and curtain air bag
systems.

•

Tampering with the side air bag sys-
tem may result in serious personal
injury. For example, do not change
the front and rear seats by placing
material near the seatbacks or by in-
stalling

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
system.

Driver and front passenger
supplemental knee air bags

The knee air bag is located in the knee
bolster, on the driver’s and front passen-
ger’s side.

All of the information, cautions

and warnings in this manual apply and
must be followed.

The knee air bag is de-

signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another type of collision are simi-
lar to those of a higher severity frontal im-
pact. It may not inflate in certain collisions.

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag
operation.

When the knee 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

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.

The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly after the collision is over
OR the knee air bag will remain inflated for
a short time.

The knee air bag operates only when the
ignition switch is placed in the ON
position.

WARNING

•

Do not place any objects between the
knee bolster and the driver’s or pas-
senger’s seat. Such objects may be-
come

dangerous

projectiles

and

cause injury if a knee air bag inflates.

•

Right after inflation, the knee 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 knee air bag system. This is to
prevent damage to or accidental in-
flation of the knee air bag system.

•

Do not make unauthorized changes
to your vehicle's electrical system or
suspension system. This could affect
proper operation of the knee air bag
system.

•

Tampering with the knee air bag sys-
tem may result in serious personal
injury. For example, do not change
the driver or passenger knee bolster
or install additional trim material
around the knee air bag.

•

It is recommended that you visit a
NISSAN dealer for work on and
around the knee air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The 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 knee
air bag system.

*The SRS wiring harness or connectors are
yellow or orange for easy identification.

When selling your vehicle, we request that
you inform the buyer about the knee air
bag system and guide the buyer to the
appropriate sections in this manual.

Safety-Seats, seat belts and supplemental restraint system

1-63

Seat belt with pretensioner(s)
(front and rear outboard seats)

WARNING

•

The pretensioner(s) cannot be re-
used 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
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 and rear out-
board seat occupants.

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.

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.

The supplemental air bag warning light

is used to indicate malfunctions in the

pretensioner system. For additional infor-
mation, see "Supplemental air bag warning
light" (P. 1-65). If the operation of the supple-
mental 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 preten-
sioner system and guide the buyer to the
appropriate

sections

•

Once a front air bag, side air bag, cur-
tain air bag or knee air bag has in-
flated, the air bag module will not
function again and must be replaced.
Additionally, the activated preten-
sioner(s) must also be replaced. The
air bag module and pretensioner(s)
should be replaced. It is recom-
mended 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, knee air bag systems and the
pretensioner system should be in-
spected if there is any damage to the
front end or side portion of the ve-
hicle. It is recommended that you
visit a NISSAN dealer for this service.

•

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 contact a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.

•

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

DISTANCE TO EMPTY (DTE)

Displays the estimated distance the vehicle
can be driven before refueling. The value is
calculated based on recent fuel economy,
the amount of fuel remaining in the fuel tank,
and the actual fuel consumption.

Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the
actual distance that can be driven.

DTE display will change to “---” when the
fuel level in the tank is getting low, prior to
the fuel gauge reaching 0 (Empty).

NOTE:
• The DTE value after refill is estimated

based on recent fuel economy and
amount of fuel added.

• If a small amount of fuel is added, or

the ignition is on during refueling, the
display may not be updated.

• Conditions that affect the fuel economy

will also affect the estimated DTE value
(city/highway driving, idle time, remote
start time, terrain, seasonal weather,
added vehicle weight, added deflectors,
roof racks, etc.).
