WARNING
Child restraint anchorages are designed
to withstand only those loads imposed by
correctly fitted child restraints. Under no
circumstances are they to be used to at-
tach 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 anchorages,
and a child could be seriously injured or
killed in a collision.
The child restraint top tether strap must be used
when installing the child restraint with the seat
belts.
Before securing the child restraint with the seat
belt, 1. If necessary, raise or remove the head restraint/headrest to position the top tether
straps over the top of the seatback. If the
head restraint/headrest is removed, store it
in a secure place. Be sure to reinstall the
head restraint/headrest when the child re-
straint is removed. For additional informa-

WARNING
● Do not secure the top tether strap to the
routing bracket. If the child restraint is
not anchored properly, the risk of a
child being injured or killed in a colli-
sion or a sudden stop greatly increases. ●
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

1.If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only place it in a front-facing direction. Always
follow the booster seat manufacturer’s in-
structions. 3. The booster seat should be positioned on
the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head
restraint/headrest is removed, store it in a
secure place. Be sure to reinstall the
head restraint/headrest when the
booster seat is removed. For additional
information, refer to “Head
restraints/headrests” in this section for head
restraint/headrest adjustment, removal and
installation information. If the seating position does not have an
adjustable head restraint/headrest and it is
interfering with the proper booster seat fit,
try another seating position or a different
booster seat.

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 does not sit in the seat properly (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 improp-
erly uses the seat belt in the ALR mode, this could
cause the air bag to be turned 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 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 touse the ALR mode may allow the restraint to tip or
move in a collision or sudden stop. This can also
result in the passenger air bag inflating in a crash
instead of being OFF. For additional information,
refer to “Child restraints” 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 notbe 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,
until you have confirmed with your dealer that
your air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The air bag system and passenger air bag status
light will take a few seconds to register a change
in the passenger seat status. For example, if a
large adult who is sitting in the front passenger
seat exits the vehicle, the passenger air bag
status light will go from OFF to ON for a few
seconds and then to OFF. This is normal system
operation and does not indicate a malfunction.
