10. Check to make sure that the child re-straint is properly secured prior to each
use. If the seat belt is not locked, repeat
steps 3 through 9.
11. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front pas-
senger air bag status light
should
illuminate. If this light is not illuminated,
refer to “Front passenger air bag and
status light” in this section. Move the
child restraint to another seating po-
sition. 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.

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 re-
straint will not be properly installed us-
ing 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. First, secure 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 seat-
back. 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 re-
moved. For additional information, refer
to “Head restraints/headrests” in this
section.
2. Position the top tether strap as shown.
3. Secure the tether strap to the tether anchor point as shown.
4. Tighten the tether strap according to the manufacturer’s instructions to re-
move any slack.
If you have any questions when install-
ing a top tether strap, it is recommended
that you visit a NISSAN dealer for this
service.

BOOSTER SEATS
For additional information on installing a
booster seat in your vehicle, follow the in-
structions outlined in this section.
Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured or killed in a sudden stop or col-
lision greatly increases: – Make sure the shoulder portion ofthe belt is away from the child’s
face and neck and the lap portion
of the belt does not cross the
stomach.
– Make sure the shoulder belt is not behind the child or under the
child’s arm.
– A booster seat must only be in- stalled in a seating position that
has a lap/shoulder belt.

3. The booster seat should be positionedon the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect 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 ad-
ditional information, refer to “Head
restraints/headrests” in this section. 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.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be
sure to follow the booster seat manu-
facturer’s instructions 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 adjust-
ing the seat belt routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat
belt with retractor” in this section. 7. If the booster seat is installed in the
front passenger seat, place the ignition
switch in the ON position. The front pas-
senger air bag status light
may or
may not illuminate, depending on the
size of the child and the type of booster
seat being used. For additional infor-
mation, refer to “Front passenger air
bag and status light” in this section.

If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect booster seat fit. If the head
restraint/headrest is removed, store it

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.
One sensor used is the occupant classifi-
cation sensor (pressure sensor). It is in the
bottom of the front passenger seat cush-
ion and is designed to detect an occupant
and objects on the seat by weight. It works
together with seat belt sensors described
in this section. 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 causethe air bag to turn OFF. Occupant classifi-
cation sensor operation can vary depend-
ing on the front passenger seat belt sen-
sors.
The front passenger seat belt sensors are
designed to detect if the seat belt is buck-
led and the amount of tension on the seat
belt, such as when it is in the Automatic
Locking Retractor (ALR) mode (child re-
straint mode). Based on the weight on the
seat detected by the occupant classifica-
tion sensor and the belt tension detected
on the seat belt, the NISSAN 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 outlined in this manual should not
cause the front passenger air bag to be
automatically turned OFF. For small adults
it may be turned OFF, however, if the occu-
pant 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 improperly uses the seat belt in
the ALR 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
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 and seat belt sensors are de-
signed 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 may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag inflating in a crash
instead of being OFF. For additional infor-
mation, refer to “Child restraints” in this sec-
tion.
If the front passenger seat is not occupied,
the front 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 de-
tected by the occupant classification sen-
sor. 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
