SEAT BELT WARNING LIGHT
Both the driver’s and passenger’s front
seats are equipped with a seat belt warn-
ing 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 “Warn-
ing lights, indicator lights and audible re-
minders” 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 abdominal
area. Contact your doctor for specific rec-
ommendations.
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 inthis 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 re-
ceive 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 up-
right 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 acti-
vated, the child can be seriously in-
jured 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.LRS0786
Safety—Seats, seat belts and supplemental restraint system1-15

2. Slowly pull the seat belt out of the re-tractor and insert the tongue into the
buckle
Auntil you hear and feel the
latch engage.
∙ The retractor is designed to lock
during 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 retractor. 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 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, re-
fer to “Child restraints” in this section.
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 ac-
tivated, it may cause uncomfortable seat
belt tension. It can also change the op-
eration 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 cer-
tain 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 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 for- ward quickly. The retractor should lock
and restrict 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, refer to “Precau-
tions on seat belt usage” in this section. To
adjust, pull out the adjustment button
1
and 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 ad-
justment button to lock the shoulder belt
anchor into position.
WARNING
∙ Af ter adjustment, release the adjust- ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
∙ The shoulder belt anchor height should be adjusted to the position
best for you. Failure to do so may re-
duce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the
lap/shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available for purchase. The ex-
tender adds approximately 8 in (200 mm)
of length and may be used for either the
driver or front passenger seating position.
It is recommended that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
∙ Only NISSAN seat belt extenders,made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
∙ Adults and children who can use the standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal injury
in the event of an accident.
∙ Never use seat belt extenders to in- stall child restraints. If the child re-
straint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.

SEAT BELT MAINTENANCE
∙To clean the seat belt webbing, apply
a mild soap solution or any solution rec-
ommended for cleaning upholstery or
carpet. Then wipe with a cloth and allow
the seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
∙ If dirt builds up in the shoulder belt
guide of the seat belt anchors, the
seat belts may retract slowly. Wipe the
shoulder belt guide with a clean, dry
cloth.
∙ Periodically check to see that the seat
belt and the metal components, such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If
loose parts, deterioration, cuts or other
damage on the webbing is found, the
entire seat belt assembly should be re-
placed.
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, re-
lease 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 re-
strained.
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 improperly fit-
ting seat belt could cause serious or fa-
tal injury. Always use appropriate child
restraints.

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
restraint 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 ve-
hicles.
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.

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 certif ying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.
∙ Check the booster seat in your vehicle to be sure it is compatible with the vehi-
cle’s seat and seat belt system. ∙ Make sure the child’s head will be prop-
erly 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 ad-
justments to be sure the booster seat is
compatible with the child. Always follow
all recommended procedures.
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.
