•Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking
Retractor (ALR) mode seat belts. If
the seat belt becomes wrapped
around a child’s neck with the ALR
mode activated, the child can be se-
riously 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 release the
child. If the seat belt cannot be un-
buckled 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.
Fastening the seat belts
1. Adjust the seat. For additional informa- tion, refer to “Seats” in this section.

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,
release 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.

8. Af ter attaching the child restraint, test itbefore you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt 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
belt holds the restraint in place. If the
restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may
need to try a different child restraint. Not
all child restraints fit in all types of
vehicles. 9. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 2
through 8.
10. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should illuminate. If this light is not illu-
minated, refer to “Front passenger air
bag and status light” in this section.
Move the child restraint to another
seating position. Have the system
checked. It is recommended that you
visit a NISSAN dealer for this service.
Af ter the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. If the front passenger air bag is OFF,
it will not inflate in a crash. The driver air bag
and other air bags in your vehicle are not
part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requir-
ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the
seat by weight. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions is on the seat, its weight and the
child’s weight can be detected and cause
the air bag to turn OFF.Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the front passenger air bag and pas-
senger knee air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however if the occupant takes
his/her weight off the seat cushion (for ex-
ample, by not sitting upright, by sitting on
an edge of the seat, or by otherwise being
out of position), this could cause the sensor
to turn the front passenger air bag and
passenger knee air bag OFF. Always be
sure to be seated and wearing the seat belt
properly for the most effective protection
by the seat belt and supplemental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag and passenger knee air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure child
restraints and to use the ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag and passenger kneeair bag inflating in a crash instead of being
OFF. For additional information, refer to
“Child restraints” in this section.
If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag are designed not to inflate in a
crash. However, heavy objects placed on
the seat could result in air bag inflation,
because of the object’s weight detected by
the occupant classification sensor. Other
conditions could also result in air bag infla-
tion, such as if a child is standing on the
seat, or if two children are on the seat, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag and passenger knee air bag
are automatically turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the front passen-
ger air bag and passenger knee air bag are
OFF), it could be that the person is a small
adult, or is not sitting on the seat properly
or not using the seat belt properly.
