2000 NISSAN ALTIMA Owners Manual

cNo unauthorized changes should be
made to any components or wiring
of the pre-tensioner seat belt sys-
tem. 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 personal in-
jury.
cWork around and on the pre-
tensioner system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN 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, con-
tact an authorized NISSAN dealer.
Correct pre-tensioner disposal pro-
cedures are set forth in the appropri-
ate NISSAN Service Manual. Incor-
rect disposal procedures could
cause personal injury.The front seat pre-tensioner seat belt sys-
tem activates in conjunction with the supple-
mental front air bag. Working with the seat
belt retractor, it helps tighten the seat belt
the instant the vehicle becomes involved in
certain types of collisions, thereby restrain-
ing 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. The smoke is not harmful, but care
should be taken not to inhale it as it may
cause irritation and choking.
If any abnormality occurs in the pre-
tensioner system, the seat belt warning light
will flash intermittently after the igni-
tion key is turned to the ON or START
position. In this case, the pre-tensioner seat
belt will not function properly.
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.

SUPPLEMENTAL AIR BAG
WARNING LABELS
Warning labels about the supplemental air
bag systems are placed in the vehicle as
shown in the illustration.
SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel,
monitors the circuits of the supplemental
front air bag system and supplemental side
air bag (if so equipped) systems. The cir-
cuits monitored by the air bag warning light
are the diagnosis sensor unit, satellite sen-
sors, front air bag modules, side air bag
modules 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 and supplemen-
tal side air bag needs servicing:
cThe supplemental air bag warning light
remains on after approximately 7 sec-
onds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light
does not come on at all.
Under these conditions, the supplemental
front air bag or supplemental side air bags
may not operate properly. It must be
checked and repaired. Take your vehicle to
the nearest authorized NISSAN dealer.
WARNING
If the supplemental air bag warning
light is on, it could mean that the
supplemental front air bag or supple-
mental side air bag system will not
operate in an accident.
Repair and replacement procedure
The supplemental front air bag modules or
supplemental side air bags are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag light remains illuminated
after inflation has occurred. Repair and re-
placement of these supplemental air bag
systems should be done only by an autho-
rized NISSAN dealer.
To ensure long-term functioning, these
supplemental air bag systems must be
inspected 10 years after the date of
manufacture as noted on the certifica-
tion label located on the driver side front
pillar.
When maintenance work is required on the
vehicle, the supplemental front air bags,
supplemental side air bags and related
parts should be pointed out to the person
conducting the maintenance. The ignition
key should always be in the LOCK position
when working under the hood or inside the
vehicle.
WARNING
cOnce the supplemental front air bag
or supplemental side air bag has
inflated, the air bag module will not
function again and must be re-
placed. The air bag module should
be replaced by an authorized
NISSAN dealer. The air bag module
cannot be repaired.
cThe supplemental front air bag and
supplemental side air bag systems
should be inspected by an autho-
rized NISSAN dealer if there is any
damage to the front end or side por-
tion of the vehicle.
cIf you need to dispose of a supple-
mental air bag or scrap the vehicle,
contact an authorized NISSAN
dealer. Correct supplemental air bag
disposal procedures are set forth in
the appropriate NISSAN Service
Manual. Incorrect disposal proce-
dures could cause personal injury.

PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly
adjusted, 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 includes
a supplemental air bag.
Most U.S. states and all Canadian prov-
inces and territories, require 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 prop-
erly restrained and, if appropriate, in
a child restraint.
c
The belt should be properly adjusted
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.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 inter-
nal injuries in an accident.

cBe sure the seat belt tongue is se-
curely fastened to the proper buckle.
cDo not wear the belt inside out or
twisted. Doing so may reduce its
effectiveness.
cDo not allow more than one person
to use the same belt.
cNever carry more people in the ve-
hicle than there are seat belts.cIf the seat belt warning light glows
continuously while the ignition is
turned ON with all doors closed and
all seat belts fastened, it may indi-
cate a malfunction in the system.
Have the system checked by an au-
thorized NISSAN dealer.
cOnce the pre-tensioner seat belt has
activated, it cannot be reused and
must be replaced together with the
retractor. See you NISSAN dealer.cRemoval and installation of the pre-
tensioner seat belt system compo-
nents should be done by an autho-
rized NISSAN dealer.
cAll seat belt assemblies including
retractors and attaching hardware
should be inspected after any colli-
sion by an authorized NISSAN
dealer. NISSAN recommends that all
seat belt assemblies in use during a
collision be replaced unless the col-
lision 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.

CHILD SAFETY
Children need adults to help protect
them. They need to be properly re-
strained.
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. Forward
facing child restraints are available for chil-
dren who outgrow rear facing child restraints.
WARNING
Infants and children need special pro-
tection. 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 improp-
erly fitting seat belt could cause seri-
ous or fatal injury. Always use appro-
priate child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. See
``Child Restraints'' later in this section.
In addition, there are many types of child
restraints available for larger children whichshould be used for maximum protection.
NISSAN recommends that all pre-teens
and children be restrained in the rear
seat if possible. According to accident
statistics, children are safer when prop-
erly restrained in the rear seat than in the
front seat. This is especially important
because your vehicle has a supplemen-
tal 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
children be placed in child restraints that
comply with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle
Safety Standards. You should choose a
child restraint that fits your vehicle and
always follow the manufacturer's instruc-
tions for installation and use.
Larger children
Children who are too large for child re-
straints 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 avail-able) may help overcome this. The booster
seat should raise the child so that the shoul-
der belt is properly positioned 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 mov-
ing. The child could be seriously in-
jured or killed in an accident.
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 possible 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 rec-
ommendations.
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 acci-
dent you could be thrown into it and
receive neck or other serious inju-
ries. You could also slide under the
lap belt and receive serious internal
injuries.

cFor 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
properly. See ªPrecautions on seat
belt usageº earlier in this section.
Fastening the seat belts
1. Adjust the seat.
2. Slowly pull the seat belt out of the retrac-
tor 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.3. Position the lap belt portionlow and
snug on the hipsas shown.
4. Pull the shoulder belt portion toward the
retractor to take up extra slack.
The front passenger seat belt and the rear
three-point seat belts have a cinching
mechanism for child restraint installation. It
is referred to as the automatic locking
mode.
When automatic locking mode is activated
the seat belt cannot be withdrawn further
until the seat belt tongue is detached from
the buckle and fully retracted. Once re-
