SEAT BELT WARNING LIGHT
Both the driver’s and passenger’s front seats are
equipped with a seat belt warning light. The
warning light, located on the instrument panel,
will show the status of the driver and passenger
seat belt.
NOTE:
The front passenger seat belt warning light
will not light up if the seat is not occupied.
For additional information, refer to “Warning
lights, indicator lights and audible reminders” in
the “Instruments and controls” section of this
manual.
PREGNANT WOMEN
NISSAN recommends that pregnant women use
seat belts. The seat belt should be worn snug and
always position the lap belt as low as possible
around the hips, not the waist. Place the shoulder
belt over your shoulder and across your chest.
Never run the lap/shoulder belt over your ab-
dominal area. Contact your doctor for specific
recommendations.
INJURED PERSONS
NISSAN recommends that injured persons use
seat belts. Check with your doctor for specific
recommendations.
THREE-POINT TYPE SEAT BELT
WITH RETRACTOR
WARNING
●Every person who drives or rides in this
vehicle should use a seat belt at all
times. ●
Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and receive
neck or other serious injuries. You
could also slide under the lap belt and
receive serious internal injuries.
● For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back and
upright in the seat with both feet on the
floor and adjust the seat belt properly.
● 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
release 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.

2. Slowly pull the seat belt out of the retractorand insert the tongue into the buckle
Auntil
you hear and feel the latch engage.
● The retractor is designed to lock dur-
ing a sudden stop or on impact. A
slow pulling motion permits the seat
belt to move and allows you some
freedom of movement in the seat.
● If the seat belt cannot be pulled from
its fully retracted position, firmly pull
the belt and release it. Then
smoothly pull the belt out of the re-
tractor. 3. Position the lap belt portion
low and snug
on the hipsBas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
C. Be sure
the shoulder belt is routed over your shoul-
der 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 extend 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 returns to the ELR mode
after the seat belt fully retracts. For additional
information, refer to “Child restraints” in this sec-
tion.
The ALR mode should be used only for
child restraint installation. During normal
seat belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt ten-
sion. It can also change the operation of
the front passenger air bag. For additional
information, refer to “Front passenger air
bag and status light” in this section.
WARNING
When fastening the seat belts, be certain
that the seatbacks are completely secured
in the latched position. If they are not
completely secured, passengers may be
injured in an accident or sudden stop.

Unfastening the seat belts
To unfasten the seat belt, press the button on the
buckle
1. The seat belt automatically 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 recommended 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 ad-
justed to the position best for you. For additional
information, refer to “Precautions on seat belt
usage” in this section. To adjust, pull out the
adjustment button
1and move the shoulder belt
anchor to the desired position
2, 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
button to lock the shoulder belt anchor into posi-
tion.

WARNING
Do not allow children to play with the seat
belts. Most seating positions are
equipped with Automatic Locking Retrac-
tor (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. Un-
buckle the seat belt to release 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, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child. There are three basic types of child restraint
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 children who outgrow rear-
facing child restraints 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 protec-
tion. 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 improperly fitting seat
belt could cause serious or fatal injury.
Always use appropriate child restraints.
All U.S. states and Canadian provinces or territo-
ries require the use of approved child restraints
for infants and small children. For additional infor-
mation, refer to “Child restraints” in this section. A child restraint may be secured in the vehicle by
using either the LATCH (Lower Anchors and
Tethers for CHildren) system or with the vehicle
seat belt. For additional information, refer to
“Child restraints” in this section.
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 restraint sys-
tem (air bag system) for the front passen-
ger. For additional information, refer to
“Supplemental Restraint System (SRS)” in
this section.INFANTS
Infants up to at least 1 year old should be placed
in a rear-facing child restraint. NISSAN recom-
mends 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.

child restraint is loose, repeat steps 1
through 4.
REAR-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.
For additional information, refer to all Warnings
and Cautions in the “Child safety” and “Child
restraints” sections of this manual before install-
ing a child restraint. Do not use the lower anchors if the combined
weight of the child and the child restraint exceeds
65 lbs (29.5 kg) . If the combined 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 anchors) to install the child restraint. Be
sure to follow the child restraint manufacturer’s
instructions for installation.
Follow these steps to install a rear-facing child
restraint using the vehicle seat belts in the rear
seats:
1.Child restraints for infants must be
used in the rear-facing direction and
therefore must not be used in the front
seat. Position the child restraint on the seat.
Always follow the child restraint manufactur-
er’s instructions.

5. Remove any additional slack from the seatbelt; press downward and rearward firmly in
the center of the child restraint to compress
the vehicle seat cushion and seatback while
pulling up on the seat belt. 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 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. 7. Check to make sure that the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 1
through 6.
After the child restraint is removed and the seat
belt fully retracted, the ALR mode (child restraint
mode) is canceled.

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 seat is 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 should be used.
● If the booster seat is compatible with your
vehicle, place the child in the booster seat
and check the various adjustments to be
sure the booster seat is compatible with the
child. Always follow all recommended pro-
cedures. 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 vehicle 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 Lock-
ing Retractor (ALR) mode when using a
booster seat with the seat belts.
For additional information, refer to all Warnings
and Cautions in the “Child safety”, “Child re-
straints” and “Booster seats” sections of this
manual before installing a child restraint.

The NISSAN Advanced Air Bag System and front
passenger air bag status light will take a few
seconds to register a change in the front passen-
ger seat status. For example, if a large adult who
is sitting in the front passenger seat exits the
vehicle, the front 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.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
of the instrument panel, will be illuminated (blink-
ing or steadily lit) . Have the system checked. It is
recommended that you visit a NISSAN dealer for
this service.
Normal operation
In order for the occupant classification sensor
system to classify the front passenger based on
weight, please follow the precautions and steps
outlined below:
Precautions
● Make sure that there are no objects weigh-
ing over 2.2 lbs (1 kg) hanging on the seat or
placed in the seatback pocket.
● Make sure that a child restraint or other
object is not pressing against the rear of the
seatback. ●
Make sure that a rear passenger is not push-
ing or pulling on the back of the front pas-
senger seat.
● Make sure that the front passenger seat or
seatback is not forced back against an ob-
ject on the seat or floor behind it.
● Make sure that there is no object placed
under the front passenger seat.
Steps 1. Adjust the seat as outlined in the “Seats” section of this manual. Sit upright, leaning
against the seatback, and centered on the
seat cushion with your feet comfortably ex-
tended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual. Front passen-
ger seat belt buckle status is monitored by
the occupant 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 al- lowing the system to classify the front pas-
senger 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 sen-
sor system generally keeps the classifica-
tion locked during driving, so it is important
that you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor
may recalculate the weight of the occupant
under some conditions (both while driving
and when stopped) , so front passenger
seat occupants 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 occupying the front passenger seat:
● Occupant is a small adult — the air bag light
is functioning as intended. The front passen-
ger air bag is 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 comfortably
extended to the floor.
