OC.Be
sure the shoulder belt is routed over
your shoulder and across your chest.
The front passenger seat and the rear
seating positions’ three-point seat belts
have two modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR) The ELR mode allows the seat belt to ex-
tend and retract to allow the driver and
passengers some freedom of movement
in the seat. The ELR locks the seat belt
when the vehicle slows down rapidly or
during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the
seat belt tongue is detached from the
buckle and fully retracted. The seat belt re-
turns to the ELR mode af ter the seat belt
fully retracts. For additional information,
see “Child restraints” (P. 1-23).
The ALR mode should be used only for
child restraint installation. During nor-
mal seat belt use by an occupant, the
ALR mode should not be activated. If it is
activated, it may cause uncomfortable
seat belt tension. It can also change
the operation of the front passenger
air bag. For additional information, see
“Front passenger air bag and status
light” (P. 1-55).
WARNING
When fastening the seat belts, be cer-
tain that the seatbacks are completely
secured in the latched position. If they
are not completely secured, passen-
gers may be injured in an accident or
sudden stop.

Unfastening the seat belts
To unfasten the seat belt, press the button
on the buckle
O1. The seat belt automati-
cally retracts.
Checking seat belt operation
Seat belt retractors are designed to lock
seat belt movement by two separate
methods:
• When the seat belt is pulled quickly from the retractor
• When the vehicle slows down rapidly To increase your confidence in the seat
belts, check the operation as follows:
• Grasp the shoulder belt and pull forward
quickly. The retractor should lock and re-
strict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service, or to learn more about seat
belt operation.
Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. For
additional information, see “Precautions on
seat belt usage” (P. 1-12). To adjust, pull out
the adjustment button
O1and move the
shoulder belt anchor to the desired posi-
tion
O2, so the belt passes over the center
of the shoulder. The belt should be away
from your face and neck, but not falling off
your shoulder. Release the adjustment but-
ton to lock the shoulder belt anchor into
position.

WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes
tight. This can occur even if the vehicle
is parked. Unbuckle the seat belt to re-
lease the child. If the seat belt cannot
be unbuckled or is already unbuckled,
release the child by cutting the seat
belt with a suitable tool (such as a knife
or scissors) to release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in
this manual, child safety information is
available from many other sources, includ-
ing doctors, teachers, government traffic
safety offices, and community organiza-
tions. Every child is different, so be sure to
learn the best way to transport your child.
There are three basic types of child re-
straint systems:
• Rear-facing child restraints • Forward-facing child restraints
• Booster seats
The proper restraint depends on the child's
size. Generally, infants up to about 1 year
and less than 20 lbs. (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for chil-
dren who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle
lap/shoulder belt on a child who can no
longer use a forward-facing child restraint.
WARNING
Infants and children need special pro-
tection. The vehicle's seat belts may
not fit them properly. The shoulder belt
may come too close to the face or neck.
The lap belt may not fit over their small
hip bones. In an accident, an improp-
erly fitting seat belt could cause serious
or fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children.
For additional information, see “Child re-
straints” (P. 1-23). A child restraint may be secured in the ve-
hicle by using either the LATCH (Lower An-
chors and Tethers for CHildren) system or
with the vehicle seat belt. For additional
information, see “Child restraints” (P. 1-23).
NISSAN recommends that all pre-teens
and children be restrained in the rear
seat. Studies show that children are
safer when properly restrained in the
rear seat than in the front seat.
This is especially important because
your vehicle has a supplemental re-
straint system (air bag system) for the
front passenger. For additional informa-
tion, see “Supplemental Restraint Sys-
tem (SRS)” (P. 1-44).
INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
NISSAN recommends that infants be
placed in child restraints that comply with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.
You should choose a child restraint that fits
your vehicle and always follow the manu-
facturer's instructions for installation and
use.

3. 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 hand to com-
press the vehicle seat cushion and seat-
back while tightening the webbing of
the anchor attachments. 4. 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.
5. Check to make sure the child restraint is properly secured prior to each use. If the
child restraint is loose, repeat steps 1
through 4.

FORWARD-FACING CHILD RESTRAINT
INSTALLATION USING LATCH
For additional information, see all Warnings
and Cautions in the “Child safety” (P. 1-21)
and “Child restraints” (P. 1-23) before install-
ing 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 LATCH system:
1. Position the child restraint on the seat. Always follow the child restraint manu-
facturer's instructions. 2. Secure the child restraint anchor at-
tachments to the LATCH lower anchors.
Check to make sure the LATCH attach-
ment is properly attached to the lower
anchors.

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.

All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved
child restraint at all times while the ve-
hicle is being operated.
The instructions in this section apply to
booster seat installation in the rear seats
or the front passenger seat.
Booster seat installation
WARNING
To avoid injury to child, do not use the
lap/shoulder belt in the Automatic
Locking Retractor (ALR) mode when us-
ing a booster seat with the seat belts.
For additional information, see all Warnings
and Cautions in the “Child safety” (P. 1-21),
“Child restraints” (P. 1-23) and “Booster seats”
(P. 1-40) 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 manu-
facturer’s instructions.

3. Fasten the seat belt as outlined in “Seatbelts” (P. 1-12). Front passenger seat belt
buckle status is monitored by the occu-
pant classification system, and is used
as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fasten their seat
belt.
4. Remain in this position for 30 seconds allowing the system to classif y the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification
sensor system generally keeps the clas-
sification locked during driving, so it is
important that you confirm that the
front passenger is properly classified
prior to driving. However, the occupant
classification sensor may recalculate the
weight of the occupant under some con-
ditions (both while driving and when
stopped), so front passenger seat occu-
pants should continue to remain seated
as outlined above.
Troubleshooting
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front
passenger air bag and front passen-
ger supplemental knee air bag are
suppressed.
However, if the occupant is not a small
adult, then this may be due to the following
conditions that may be interfering with the
weight sensors:
• Occupant is not sitting upright, leaning against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.
• A child restraint or other object pressing against the rear of the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
•
Forcing the front seat or seatback against
an object on the seat or floor behind it.
• An object placed under the front passen- ger seat. • An object placed between the seat cush-
ion and center console or between the
seat cushion and the door.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON af ter this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• Small adult or child is not sitting upright, leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.
