NISSAN QUEST 2002 V41 / 2.G Service Manual

Supplemental front air bag system
The driver supplemental air bag is located in
the center of the steering wheel. The front
passenger supplemental air bag is mounted in
the dashboard above the glove box.
These systems are designed to meet optional
certification requirements under U.S. regula-
tions. They are also permitted in Canada. The
optional certification allows front air bags to
be designed to inflate somewhat less force-
fully than previously.However, all of the
information, cautions and warnings in this
manual still apply and must be followed.
The supplemental front air bag system is
designed to inflate in higher severity frontal
collisions, although it may inflate if the forces
in another type of collision are similar to those
of a higher severity frontal impact. It may not
inflate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indica-
tion of proper supplemental air bag system
operation.
When the supplemental front air bag in-
flates, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indicate
a fire. Care should be taken to not intention-ally inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
The supplemental front air bags, along with
the use of seat belts, help to cushion the
impact force on the face and chest of the
occupant. They can help save lives and
reduce serious injuries. However, an inflat-
ing front air bag may cause facial abrasions
or other injuries. Front air bags do not
provide restraint to the lower body.
Seat belts should be correctly worn and the
driver and passenger seated upright as far
away as practical from the steering wheel or
instrument panel. The supplemental front air
bag inflates 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 module
during inflation.The air bag deflates quickly
after a collision.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
After turning the ignition key to the ON
position, the supplemental air bag warn-

ing light illuminates. The supplemental
air bag warning light will turn off after
about 7 seconds if the system is opera-
tional.WARNING
cDo 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 supplemental front air bag
inflates.
cRight after inflation, several air bag
system components will be hot. Do
not touch them; you may severely
burn yourself.
cNo unauthorized changes should be
made to any components or wiring
of the supplemental front air bag
system. This is to prevent accidental
inflation of the air bag or damage to
the air bag system.
cDo not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the supplemental front
air bag system.cTampering with the supplemental
front air bag system may result in
serious personal injury. Tampering
includes changes to the steering
wheel and the instrument panel as-
sembly by placing material over the
steering wheel pad and above the
instrument panel or by installing ad-
ditional trim material around the air
bag system.
cWork around and on the supplemen-
tal front air bag system should be
done by an authorized NISSAN
dealer. Installation of electrical
equipment should also be done by
an authorized NISSAN dealer. The
Supplemental Restraint System
(SRS) wiring should not be modified
or disconnected. Unauthorized elec-
trical test equipment and probing
devices should not be used on the
air bag system.
cA cracked windshield should be re-
placed immediately by a qualified
repair facility. A cracked windshield
could affect inflation of the supple-
mental air bag system.

When selling your vehicle, we request that
you inform the buyer about the supplemen-
tal air bag system and guide the buyer to the
appropriate sections in this owner's manual.
Pre-tensioner seat belt system (For
front seats)
WARNING
cThe pre-tensioner seat belt cannot
be reused after activation. It must be
replaced together with the retractor
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 necessary, replaced
by your NISSAN dealer.
cNo unauthorized changes should be
made to any components or wiring
of the pre-tensioner seat belt sys-
tem. This is to prevent accidentalactivation 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
NISSAN dealer. Unauthorized electri-
cal test equipment and probing de-
vices 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 beltthe 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 and does
not indicate a fire. Care should be taken to
not intentionally 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 air bag 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.

then turns off. This means the system is
operational.
If any of the following conditions occur, the
supplemental air bag and pre-tensioner
seat belt systems need servicing and
should be taken to your nearest authorized
NISSAN dealer.
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
air bag and/or pre-tensioner seat belts may
not operate properly. It must be checked
and repaired. Take your vehicle to the near-
est authorized NISSAN dealer.
WARNING
If the supplemental air bag warning
light is on, it could mean that the
supplemental front air bag system will
not operate in an accident.
Repair and replacement procedure
The supplemental front air bag modules are
designed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag light remains illumi-
nated after inflation has occurred. Repair
and replacement of the air bag system
should be done only by an authorized NIS-
SAN dealer.
When maintenance work is required on the
vehicle, the supplemental front air bag sys-
tem 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
inflates, the air bag module will not
function again and should be re-
placed by an authorized NISSAN
dealer. The air bag module cannot be
repaired.
cThe supplemental front air bag sys-
tem should be inspected by an au-
thorized NISSAN dealer if there is
any damage to the front end portion
of the vehicle or replaced if the
supplemental air bag has inflated.
c
If you need to dispose of a supple-
mental air bag or scrap the vehicle,
contact an authorized NISSAN dealer.
Correct supplemental air bag dis-
posal procedures are set forth in the
appropriate NISSAN Service Manual.

PRECAUTIONS ON SEAT BELT
USAGE
Your chances of being injured or killed in an
accident and/or the severity of injury may be
greatly reduced if you are wearing your seat
belt and it is properly adjusted. 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 Canadian prov-
inces or 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 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 accident. Seri-
ous 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 seat 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.
c
All seat belt assemblies, including
retractors and attaching hardware,
should be inspected after any colli-
sion by an authorized NISSAN dealer.
NISSAN recommends that all seatbelt assemblies in use during a colli-
sion be replaced unless 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 dam-
age or improper operation is noted.

cAll child restraints and attaching
hardware should be inspected after
any collision. Always follow the re-
straint manufacturer's inspection in-
structions and replacement recom-
mendations. The child restraints
should be replaced if they are dam-
aged.
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. Forward facing child re-
straints are available for children 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 US States and Canadian provinces re-
quire 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
restraints 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 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 supplemental restraint sys-
tem (Air bag system) for the front passen-ger (For precautions, see ``Supplemental
restraint system'' earlier in this section).
Infants and small children
NISSAN recommends that infants and small
children be placed in a child restraint that
complies with the Federal Motor Vehicle
Safety Standards or Canadian Motor Ve-
hicle 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 available)
may help overcome this. The booster seat
should raise the child so the shoulder 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 Motor Ve-
hicle Safety Standards. Once the child has
Seats, restraints and supplemental air bag systems1-41
ZX

grown enough 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 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 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 injured persons use
seat belts, depending on the injury. Check
with your doctor for specific recommenda-
tions.
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.
c
Do 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 accidentyou could be thrown into it and re-
ceive neck or other serious injuries.
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 seat passenger seat belt and rear
three-point seat belts have a cinching
mechanism for child restraint installation. It is
referred to as the automatic locking mode.
When the automatic locking mode is acti-
vated, the seat belt cannot be withdrawn
again until the seat belt tongue is detached
from the buckle and fully retracted. Refer to``Child restraints'' later in this section for
more information.
The automatic locking mode should be
used only for child restraint installation.
During normal seat belt use by a passen-
ger, the locking mode should not be
activated. If it is activated, it may cause
uncomfortable seat belt tension.
