∙If dirt builds up in the shoulder belt
guide of the seat belt anchors, the
seat belts may retract slowly. Wipe the
shoulder belt guide with a clean, dry
cloth.
∙ Periodically check to see that the seat
belt and the metal components, such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If
loose parts, deterioration, cuts or other
damage on the webbing is found, the
entire seat belt assembly should be re-
placed.WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes
tight. This can occur even if the vehicle
is parked. Unbuckle the seat belt to re-
lease the child. If the seat belt cannot be
unbuckled or is already unbuckled, re-
lease the child by cutting the seat belt
with a suitable tool (such as a knife or
scissors) to release the seat belt.
Children need adults to help protect
them. They need to be properly re-
strained.
In addition to the general information in
this manual, child safety information is
available from many other sources, includ-
ing doctors, teachers, government traffic
safety offices, and community organiza-
tions. Every child is different, so be sure to
learn the best way to transport your child.
There are three basic types of child re-
straint systems: ∙ Rear-facing child restraints
∙ Forward-facing child restraints
∙ Booster seats
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year
and less than 20 lbs. (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for chil-
dren who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle
lap/shoulder belt on a child who can no
longer use a forward-facing child restraint.
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 improperly fit-
ting seat belt could cause serious or fa-
tal injury. Always use appropriate child
restraints.

3. For child restraints that are equippedwith webbing-mounted attachments,
remove any additional slack from the
anchor attachments. Press downward
and rearward firmly in the center of the
child restraint with your hand to com-
press the vehicle seat cushion and
seatback while tightening the webbing
of the anchor attachments. 4. Af ter attaching the child restraint, test
it before you place the child in it. Push it
from side to side while holding the child
restraint near the LATCH attachment
path. The child restraint should not
move more than 1 inch (25 mm), from
side to side. Try to tug it forward and
check to see if the LATCH attachment
holds the restraint in place. If the re-
straint is not secure, tighten the LATCH
attachment as necessary, or put the
restraint in another seat and test it
again. You may need to try a different
child restraint or try installing by using the vehicle seat belt (if applicable). Not
all child restraints fit in all types of ve-
hicles.
5. Check to make sure the child restraint is properly secured prior to each use. If
the child restraint is loose, repeat
steps 1 through 4.

RESTRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must be
used when installing a child restraint.
Failure to use the ALR mode will result in
the child restraint not being properly
secured. The restraint could tip over or
be loose and cause injury to a child in a
sudden stop or collision. Also, it can
change the operation of the front pas-
senger air bag. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and the child
restraint is greater than 65 lbs. (29.5 kg), use
the vehicle’s seat belt (not the lower an-
chors) to install the child restraint. Be sure
to follow the child restraint manufacturer’s
instructions for installation. Follow these steps to install a forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front passen-
ger seat:
1. If you must install a child restraint in
the front seat, it should be placed in a
forward-facing direction only. Move
the seat to the rearmost position.
Child restraints for infants must be
used in the rear-facing direction and,
therefore, must not be used in the
front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should
be secured against the vehicle seat-
back.
If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect child restraint fit. If the head
restraint/headrest (if so equipped) is
removed, store it in a secure place. Be
sure to reinstall the head
restraint/headrest (if so equipped)
when the child restraint is removed.

∙ Make sure the child’s head will be prop-erly supported by the booster seat or
vehicle seat. The seatback must be at
or above the center of the child’s ears.
For example, if a low back booster seat
is chosen, the vehicle seatback must be
at or above the center of the child’s ears.
If the seatback is lower than the center
of the child’s ears, a high back booster
seat should be used. ∙ If the booster seat is compatible with
your vehicle, place the child in the
booster seat and check the various ad-
justments to be sure the booster seat is
compatible with the child. Always follow
all recommended procedures.
All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved
child restraint at all times while the ve-
hicle is being operated.
The instructions in this section apply to
booster seat installation in the rear seats
or the front passenger seat.Booster seat installation
WARNING
To avoid injury to child, do not use the
lap/shoulder belt in the Automatic
Locking Retractor (ALR) mode when us-
ing a booster seat with the seat belts.
For additional information, refer to all Warn-
ings and Cautions in the “Child safety”,
“Child restraints” and “Booster seats” sec-
tions of this manual before installing a child
restraint. Follow these steps to install a booster seat
in the rear seat or in the front passenger

∙ Make sure that a rear passenger is notpushing 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.
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 is 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.

SUPPLEMENTAL AIR BAG WARNING
LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel,
monitors the circuits for the air bag sys-
tems, pretensioner(s) and all related wiring.
When the ignition is placed in the ON or
START position, the supplemental air bag
warning light illuminates for about 7 sec-
onds and then turns off. This means the
system is operational. If any of the following conditions occur, the
front air bag, side air bag and curtain air
bag and pretensioner systems need ser-
vicing:
∙ The supplemental air bag warning light remains on af ter approximately 7 sec-
onds.
∙ The supplemental air bag warning light flashes intermittently.
∙ The supplemental air bag warning light does not come on at all.
Under these conditions, the front air bag,
side air bag and curtain air bag or preten-
sioner systems may not operate properly.
They must be checked and repaired. It is
recommended that you visit a NISSAN
dealer for this service.WARNING
If the supplemental air bag warning
light is on, it could mean that the front
air bag, side air bag, curtain air bag
and/or pretensioner systems will not
operate in an accident. To help avoid
injury to yourself or others, have your
vehicle checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags and pretensioner(s) are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag warning light remains illu-
minated af ter inflation has occurred. These
systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.
