5. 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 knee to com-
press the vehicle seat cushion and
seatback while tightening the webbing
of the anchor attachments.
6. Tighten the tether strap according to the manufacturer’s instructions to re-
move any slack. 7. 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 re-
straint 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 vehicles.
8. Check to make sure the child restraint is properly secured prior to each use. If
the child restraint is loose, repeat
steps 2 through 7.

WARNING
Child restraint anchorages are de-
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
restraint will not be properly installed
using the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

FORWARD-FACING CHILD
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 correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child
restraint is removed.
For additional
information about head restraint/
headrest adjustment, removal and
installation, refer to “Head restraints/
headrests” in this section.

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 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 knee
air bag inflating in a crash instead of beingOFF. For additional information about
proper use and installation, 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.
If a child restraint must be used in the front
seat, the front passenger air bag status
