signed to withstand only those loads
imposed by correctly fitted child re-
straints. Under no circumstances are
they to be used to attach adult seat
belts, or other items or equipment to
the vehicle. Doing so could damage the
child restraint anchorages. The child re-
straint will not be properly installed us-
ing the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rearseat 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 press- ing against the rear of the seatback,
such as a child restraint installed 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 restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
and passenger knee air bag may de-
ploy in a collision. Also the front pas-
senger air bag status light may not
illuminate. For additional information
about installing and using child re-
straints, refer to "Child restraints" in
this section.
∙ 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 occu-
pant classification system is working
properly, 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 supple-
mental 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
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
Safety—Seats, seat belts and supplemental restraint system1-55

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 inthe 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 classif y 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” 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.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual.
Front passenger seat belt buckle sta-
tus is monitored by the occupant clas-
sification system, and is used as an in-
put to determine occupancy status. So,
it is highly recommended that the front
passenger fasten their seat belt.
4. Remain in this position for 30 seconds allowing the system to classif y the
front passenger before the vehicle is
put into motion.
Safety—Seats, seat belts and supplemental restraint system1-59

5. Ensure proper classification by check-ing 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 passenger air bag and passenger
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 pas- senger seat.
∙ An object placed between the seat cushion 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 af ter 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 con-
ditions 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 re-
straints” section of this manual.
∙ An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the
seatback pocket.

∙ 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 pas- senger seat.
∙ An object placed between the seat cushion 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 af ter 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 passen-
ger and no objects on the front pas-
senger seat, the vehicle should be
checked. It is recommended that you
visit a NISSAN dealer as soon as pos-
sible.
Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer- ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter 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 damage
to the supplemental air bag system. ∙ Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. 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 in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury.
Safety—Seats, seat belts and supplemental restraint system1-61

∙ It is recommended that you visit aNISSAN dealer for work on and around
the knee air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equip-
ment. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the knee air
bag system.
*The SRS wiring harness or connectors
are yellow or orange for easy identifica-
tion.
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.Seat belt with pretensioner(s)
(front and rear outboard seats)
WARNING
∙ The pretensioner(s) cannot be reused af ter activation. They must be re-
placed 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

∙ No unauthorized changes should be made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental acti-
vation of the pretensioner(s). Tamper-
ing 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 rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical
test equipment and probing devices
should not be used on the preten-
sioner 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.
