2004 NISSAN ALTIMA belt

Pre-tensioner seat belt system (For
front seats)
WARNING
cThe pre-tensioner seat belt cannot be
reused after activation. It must be re-
placed together with the retractor and
buckle as a unit.
cIf the vehicle becomes involved in a
frontal collision but the pre-tensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
cNo unauthorized changes should be
made to any components or wiring of
the pre-tensioner seat belt system. This
is to prevent accidental activation of
the pre-tensioner seat belt or damage
to the pre-tensioner seat belt operation.
Tampering with the pre-tensioner seat
belt system may result in serious per-
sonal injury.cWork around and on the pre-tensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
cIf you need to dispose of the pre-
tensioner or scrap the vehicle, contact a
NISSAN dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate NISSAN Service Manual.
Incorrect disposal procedures could
cause personal injury.
The front seat pre-tensioner seat belt system
activates in conjunction with the supplemental air
bag systems. Working with the seat belt retrac-
tor, it helps tighten the seat belt when the vehicle
becomes involved in certain types of collisions,
helping to restrain front seat occupants.
The pre-tensioner is encased with the seat belt’s
retractor. These seat belts are used the same as
conventional seat belts.When the pre-tensioner seat belt activates,
smoke is released and a loud noise may be heard.
This smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
If any abnormality occurs in the pre-tensioner
system, the supplemental air bag warning
light
will not come on, will flash intermit-
tently or will turn on for 7 seconds and remain on
after the ignition key has been turned to the ON or
START position. In this case, the pre-tensioner
seat belt may not function properly. They must be
checked and repaired. Take your vehicle to the
nearest NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pre-tensioner seat belt
system and guide the buyer to the appropriate
sections in this Owner’s Manual.

The supplemental air bag warning light,
displayingin the instrument panel, moni-
tors the circuits of the supplemental front air bag,
supplemental side air bag and curtain side-
impact air bag (if so equipped) and pre-tensioner
seat belt systems. The circuits monitored by the
supplemental air bag warning light are the diag-
nosis sensor unit, crash zone sensor, satellite
sensors, front air bag modules, side air bag mod-
ules, curtain side-impact air bag modules, pre-
tensioner seat belts and all related wiring.When the ignition key is in the ON or START
position, the supplemental air bag warning light
illuminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag and curtain side-impact air bag (if so
equipped) and pre-tensioner seat belt systems
need servicing:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.

PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly ad-
justed and you are sitting upright and well back in
your seat, your chances of being injured or killed
in an accident and/or the severity of injury may be
greatly reduced. NISSAN strongly encourages
you and all of your passengers to buckle up every
time you drive, even if your seating position in-
cludes a supplemental air bag.Most U.S. states and Canadian provinces
or territories specify that seat belts be worn
at all times when a vehicle is being driven.

WARNING
cEvery person who drives or rides in this
vehicle should use a seat belt at all
times. Children should be properly re-
strained in the rear seat and, if appro-
priate, in a child restraint.
WARNING
cThe seat belt should be properly ad-
justed to a snug fit. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an acci-
dent. Serious injury or death can occur
if the seat belt is not worn properly.

WARNING
cAlways route the shoulder belt over
your shoulder and across your chest.
Never run the belt behind your back,
under your arm or across your neck. The
belt should be away from your face and
neck, but not falling off your shoulder.
cPosition the lap belt as low and snug as
possible AROUND THE HIPS, NOT THE
WAIST. A lap belt worn too high could
increase the risk of internal injuries in
an accident.cBe sure the seat belt tongue is securely
fastened to the proper buckle.
cDo not wear the seat belt inside out or
twisted. Doing so may reduce its
effectiveness.
cDo not allow more than one person to
use the same seat belt.
cNever carry more people in the vehicle
than there are seat belts.
cIf the seat belt warning light glows con-
tinuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked by a NISSAN dealer.
cOnce the pre-tensioner seat belt has
activated, it cannot be reused and must
be replaced together with the retractor.
See your NISSAN dealer.
cRemoval and installation of the pre-
tensioner seat belt system components
should be done by a NISSAN dealer.cAll seat belt assemblies, including re-
tractors and attaching hardware,
should be inspected after any collision
by a NISSAN dealer. NISSAN recom-
mends that all seat belt assemblies in
use during a collision be replaced un-
less the collision was minor and the
belts show no damage and continue to
operate properly. Seat belt assemblies
not in use during a collision should also
be inspected and replaced if either
damage or improper operation is noted.
cAll child restraints and attaching hard-
ware should be inspected after any col-
lision. Always follow the restraint
manufacturer’s inspection instructions
and replacement recommendations.
The child restraints should be replaced
if they are damaged.
CHILD SAFETY
Children need adults to help protect them.
They need to be properly restrained.
The proper restraint depends on the child’s size.
Generally, infants up to about 1 year and less
than 20 pounds (9 kg) should be placed in rear
facing child restraints. Front facing child re-
straints are available for children who outgrow
rear facing child restraints.

WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly fit-
ting seat belt could cause serious or fatal
injury. Always use appropriate child
restraints.
All U.S. states and Canadian provinces or terri-
tories require the use of approved child restraints
for infants and small children. See “Child Re-
straints” later in this section.
In addition, there are many types of child re-
straints available for larger children which should
be used for maximum protection.
NISSAN recommends that all pre-teens
and children be restrained in the rear seat.
According to accident statistics, children
are safer when properly restrained in the
rear seat than in the front seat. This is
especially important because your vehicle
has a supplemental restraint system (Air
bag system) for the front passenger. See
“Supplemental restraint system” earlier in
this section.
Infants and small children
NISSAN recommends that infants and small chil-
dren be placed in child restraints that comply with
Federal Motor Vehicle Safety Standards or Ca-
nadian Motor Vehicle Safety Standards. You
should choose a child restraint that fits your ve-
hicle and always follow the manufacturer’s in-
structions for installation and use.
Larger children
Children who are too large for child restraints
should be seated and restrained by the seat belts
which are provided.
If the child’s seating position has a shoulder belt
that fits close to the face or neck, the use of a
booster seat (commercially available) may help
overcome this. The booster seat should raise the
child so that the shoulder belt is properly posi-
tioned across the top, middle portion of the
shoulder and the lap belt is low on the hips. The
booster seat should fit the vehicle seat and have
a label certifying that it complies with Federal
Motor Vehicle Safety Standards or Canadian Mo-
tor Vehicle Safety Standards. Once the child has
grown so the shoulder belt is no longer on or near
the face and neck, use the shoulder belt without
the booster seat.
WARNING
Never let a child stand or kneel on any
seat and do not allow a child in the cargo
areas while the vehicle is moving. The
child could be seriously injured or killed in
an accident or sudden stop.
PREGNANT WOMEN
NISSAN recommends that pregnant women use
seat belts. The seat belt should be worn snug,
and always position the lap belt as low as pos-
sible around the hips, not the waist. Place the
shoulder belt over your shoulder and across your
chest. Never run the lap/shoulder belt over your
abdominal area. Contact your doctor for specific
recommendations.
INJURED PERSONS
NISSAN recommends that injured persons use
seat belts. Check with your doctor for specific
recommendations.

THREE-POINT TYPE SEAT BELT
WITH RETRACTOR
WARNING
cEvery person who drives or rides in this
vehicle should use a seat belt at all
times.
cDo not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and receive
neck or other serious injuries. You
could also slide under the lap belt and
receive serious internal injuries.
cFor the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back in the
seat and adjust the seat belt properly.
Fastening the seat belts
s1Adjust the seat. See “Seats” earlier in this
section.
s2Slowly pull the seat belt out of the retractor
and insert the tongue into the buckle until
you hear and feel the latch engage.
The retractor is designed to lock during a
sudden stop or on impact. A slow pulling
motion permits the seat belt to move, and
allows you some freedom of movement in
the seat.Manual front seat shown
