3. For child restraints that are equipped with
webbing-mounted attachments, remove any
additional slack from the anchor attach-
ments. Press downward and rearward firmly
in the center of the child restraint with your
hand to compress the vehicle seat cushion
and seatback while tightening the webbing
of the anchor attachments.4. After attaching the child restraint, test it be-
fore you place the child in it. Push it from side
to side while holding the seat 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 restraint 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. Not all child re-
straints fit in all types of vehicles.

CHILD RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
●Even with the NISSAN Advanced Air
Bag System, never install a rear-facing
child restraint in the front passenger
seat. Front air bags inflate with great
force. A rear-facing child restraint could
be struck by the front air bag in a crash
and could seriously injure or kill your
child.●NISSAN recommends that child re-
straints be installed in the rear seat.
However, if you must install a front-
facing child restraint in the front pas-
senger seat, move the passenger seat
to the rearmost position. Also, be sure
the front passenger air bag status light
is illuminated to indicate the passenger
air bag is OFF. See “Front passenger air
bag and status light” later in this sec-
tion for details
●The three-point seat belt in your vehicle
is equipped with an Automatic Locking
Retractor (ALR) which 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
otherwise be unsecured and cause in-
jury to the child in a sudden stop or
collision. Also, it can change the opera-
tion of the front passenger air bag. See
“Front passenger air bag and status
light” later in this section.

●When using the rear center seat belt to
install a child restraint, make sure the
connector tongue and the seat belt
tongue are secured. Do not use the seat
belt with only the seat belt tongue at-
tached. This could result in serious per-
sonal injury in case of an accident or
sudden stop.
●A child restraint with a top tether strap
should not be used in the front passen-
ger seat.
The instructions in this section apply to child
restraint installation using the vehicle seat belts in
the rear seat or the front passenger seat.
Front-facing
Follow these steps to install a front-facing child
restraint using the vehicle seat belt in the rear
seats or in the front passenger seat:
1.If you must install a child restraint in
the front seat, it should be placed in a
front-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. Al-
ways follow the child restraint manufactur-
er’s instructions
The back of the child restraint should be secured
against the vehicle seatback.
If necessary, adjust or remove the head restraint
to obtain the correct child restraint fit. See “Head
restraint adjustment” in this section.
If the head restraint is removed, store it in a
secure place. Be sure to reinstall the head re-
straint when the child restraint is removed.
If the seating position does not have an adjust-
able head restraint and it is interfering with the
proper child restraint fit, try another seating posi-
tion or a different child restraint.

6. Remove any additional slack from the seat
belt; press downward and rearward firmly in
the center of the child restraint with your
knee to compress the vehicle seat cushion
and seatback while pulling up on the seat
belt.7. If the child restraint is equipped with a top
tether strap, route the top tether strap and
secure the tether strap to the tether anchor
point (rear seat installation only) . See “Top
tether strap child restraint” in this section.
Do not install child restraints that require the
use of a top tether strap to seating positions
that do not have a top tether anchor.8. After attaching the child restraint, test it be-
fore you place the child in it. Push it from side
to side while holding the seat 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 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 re-
straints fit in all types of vehicles.
9. Check that the retractor is in the ALR mode
by trying to pull more seat belt out of the
retractor. If you cannot pull any more belt
webbing out of the retractor, the retractor is
in the ALR mode.
10. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 3
through 8.

●After placing the child in the booster
seat and fastening the seat belt, make
sure the shoulder portion of the belt is
away from the child’s face and neck and
the lap portion of the belt does not
cross the abdomen.
●Do not put the shoulder belt behind the
child or under the child’s arm. If you
must install a booster seat in the front
seat, see “Booster seat installation”
later in this section.
●When your booster seat is not in use,
keep it secured with a seat belt to pre-
vent it from being thrown around in
case of a sudden stop or accident.
CAUTION
Remember that a booster seat left in a
closed vehicle can become very hot.
Check the seating surface and buckles
before placing your child in the booster
seat.Booster seats of various sizes are offered by
several manufacturers. When selecting any
booster seat, keep the following points in mind:
●Choose only a booster seat with a label
certifying that it complies with Federal Motor
Vehicle Safety Standard 213 or Canadian
Motor Vehicle Safety Standard 213.
●Check the booster seat in your vehicle to be
sure it is compatible with the vehicle’s seat
and seat belt system.●Make sure the child’s head will be properly
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 seat1is 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
2should be used.
●If the booster seat is compatible with your
vehicle, place your child in the booster seat
and check the various adjustments to be
sure the booster seat is compatible with your
child. Always follow all recommended pro-
cedures.

3. The booster seat should be positioned on
the vehicle seat so that it is stable. If neces-
sary, adjust or remove the head restraint to
obtain the correct booster seat fit. See
“Head restraint adjustment” earlier in this
section.
If the head restraint is removed, store it in a
secure place. Be sure to reinstall the head
restraint when the booster seat is removed.
If the seating position does not have an
adjustable head restraint and it is interfering
with the proper booster seat fit, try another
seating position or a different booster seat.4. Position the lap portion of the seat belt low
and snug on the child’s hips. Be sure to
follow the booster seat manufacturer’s in-
structions for adjusting the seat belt routing.
5. Pull the shoulder belt portion of the seat belt
toward the retractor to take up extra slack.
Be sure the shoulder belt is positioned
across the top, middle portion of the child’s
shoulder. Be sure to follow the booster seat
manufacturer’s instructions for adjusting the
seat belt routing.

tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . Based on the
weight on the seat detected by the occupant
classification sensor and the belt tension de-
tected on the seat belt, the Advanced Air Bag
System determines whether the front passenger
air bag should be automatically turned OFF as
required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger 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 cush-
ion (for example, 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. In addition, if the occupant
improperly uses the seat belt in the ALR mode
(child restraint mode) , this could cause the air
bag to be turned OFF. Always be sure to beseated 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 chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the ALR mode (child restraint mode) may
allow the restraint to tip or move in an accident or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. See “Child restraints” earlier in this section
for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is 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 inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.Using the passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the passen-
ger air bag status light is illuminated (indicating
that the air bag is 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 passenger air bag status light may or may not
be illuminated, depending on the size of the child
and the type of child restraint being used. If the air
bag status light is not illuminated (indicating 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 occupant is positioned properly. If the air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF) . Your NISSAN dealer can check that the
system is OFF by using a special tool. However,
