3. The back of the child restraint should besecured against the vehicle seatback.
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.
See “Head restraints/headrests” in this sec-
tion for head restraint/headrest adjustment
information. If the seating position does not have an
adjustable head restraint/headrest and it is
interfering with the proper child restraint fit,
try another seating position or a different
child restraint.
4. For child restraints that are equipped withwebbing-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
knee to compress the vehicle seat cushion
and seatback while tightening the webbing
of the anchor attachments.
5. Tighten the tether strap according to the manufacturer’s instructions to remove any
slack.

6. After attaching the child restraint, test it be-fore you place the child in it. Push it from side
to side while holding the child restraint near
the LATCH attachment path. The child re-
straint 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 at-
tachment 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 restraints fit in all types of vehicles. 7. Check to make sure the child restraint is
properly secured prior to each use. If the
child restraint is loose, repeat steps 1
through 6.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
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 passenger air bag. See
“Supplemental air bag warning light” in
this section. Refer to all Warnings and Cautions in the “Child
Safety” and “Child Restraint” sections before in-
stalling a child restraint.
Follow these steps to install a forward-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
forward-facing direction only. Move
the seat to the rearmost position. Child
restraints for infants must be used in
the rear-facing direction and, there-
fore, 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/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.
See “Head restraints/headrests” in this sec-
tion 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 child restraint fit,
try another seating position or a different
child restraint. 3. Route the seat belt tongue through the child
restraint and insert it into the buckle until you
hear and feel the latch engage. Be sure to
follow the child restraint manufacturer’s in-
structions for belt routing.
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. See “Installing top tether strap” in this
section. Do not install child restraints that
require the use of a top tether strap in seat-
ing positions that do not have a top tether
anchor. 4. Pull the shoulder belt until the belt is fully
extended. At this time, the seat belt retractor
is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . It reverts to
Emergency Locking Retractor (ELR) mode
when the seat belt is fully retracted.

5. Allow the seat belt to retract. Pull up on theshoulder belt to remove any slack in the belt. 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. Tighten the tether strap according to the manufacturer’s instructions to remove any
slack. 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 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 isproperly 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 the frontpassenger seat, place the ignition switch in
the ON position. The front passenger air bag
status light
should illuminate. If this
light is not illuminated, see “Supplemental
air bag warning light” in this section. Move
the child restraint to another seating
position. Have the system checked by a
NISSAN dealer.
After the child restraint is removed and the seat
belt is fully retracted, the ALR mode (child re-
straint mode) is canceled.
INSTALLING TOP TETHER STRAP
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 anchorage,
and a child could be seriously injured or
killed in a collision.

First, secure the child restraint with the LATCH
lower anchors (rear outboard seat positions only)
or the seat belt, as applicable.1. Flip up the anchor cover
1from the anchor
point which is located directly behind the
child seat.
2. Position the top tether strap over the top of the head rest.
3. Secure the tether strap to the tether anchor point on the rear parcel shelf.
4. Refer to the appropriate child restraint in- stallation procedure steps in this section
before tightening the tether strap.
If you have any questions when installing a
top tether strap, consult your NISSAN
dealer for details.
BOOSTER SEATS
Precautions on booster seats
WARNING
If a booster seat and seat belt are not used
properly, the risk of a child being injured in
a sudden stop or collision greatly
increases: – 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 stomach.
– Make sure the shoulder belt is not behind the child or under the child’s
arm.
– A booster seat must only be installed in a seating position that has a
lap/shoulder belt.

Booster seat installation
CAUTION
Do not use the lap/shoulder belt in the
Automatic Locking Retractor mode when
using a booster seat with the seat belts.
Refer to all Warnings and Cautions in the “Child
safety”, “Child restraints” and “Booster seats”
sections before installing a child restraint.
Follow these steps to install a booster seat in the
rear seat or in the front passenger seat:
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. See “Head
restraints/headrests” in this section for head
restraint/headrest adjustment, removal and
installation information.

Status light
The front passenger air bag status light
is
located above the audio controls. After the igni-
tion switch is placed in the ONposition, the
front passenger air bag status light on the instru-
ment panel illuminates for about 7 seconds and
then turns off or remains illuminated depending
on the front passenger seat occupied status. The
light operates as follows:
● Unoccupied passenger’s seat: The
is
OFF and the front passenger air bag is OFF
and will not inflate in a crash.
● Passenger’s seat occupied by a small adult,
child or child restraint as outlined in this
section: The
illuminates to indicate
that the front passenger air bag is OFF and
will not inflate in a crash.
● Occupied passenger seat and the passen-
ger meet the conditions outlined in this sec-
tion: The light
is OFF to indicate that
the front passenger air bag is operational.
Front passenger air bag
The front passenger air bag is designed to auto-
matically turn OFF when the vehicle is operated
under some conditions as described below in
accordance with U.S. regulations. 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 requiring the air bag to be auto-
matically turned OFF. Certain sensors are used to
meet the requirements.
The occupant classification sensors (weight sen-
sors) are on the seat cushion frame under the
front passenger seat and are designed to detect
an occupant and objects on the seat. For ex-
ample, if a child is in the front passenger seat, the
Advanced Air Bag System is designed to turn the
passenger air bag OFF in accordance with the
regulations. Also, if a child restraint of the type
specified in the regulations is on the seat, the
occupant classification sensors can detect it and
cause the air bag to turn OFF.
The front passenger seat belt sensor is designed
to detect if the seat belt is buckled. Based on the
weight on the seat detected by the occupant
classification sensor and the buckle state, the
Advanced Air Bag System determines whether
the front passenger air bag should be automati-
cally 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. Always be sure to be seated and
wearing the seat belt properly for the most effec-
tive 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” 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
