•Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking
Retractor (ALR) mode seat belts. If
the seat belt becomes wrapped
around a child’s neck with the ALR
mode activated, the child can be se-
riously 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 un-
buckled 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.
Fastening the seat belts
1. Adjust the seat. For additional informa- tion, see “Seats” (P. 1-2).

2. Slowly pull the seat belt out of the retrac-tor and insert the tongue into the buckle
OAuntil 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.

4. Pull the shoulder belt portion toward the retractor to take up extra slack
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 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, see “Front
passenger air bag and status light”
(P. 1-57).
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. 1-47).
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.

6. Af ter attaching the child restraint, test itbefore 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.
7. Check to make sure the child restraint is properly secured prior to each use. If the
child restraint is loose, repeat steps 2
through 6.
8. Type A (if so equipped):
If you remove the child restraint, reinstall
the plastic LATCH anchor covers af ter
use by pushing the covers straight onto
the LATCH anchors.
Type B (if so equipped):
If you remove the child restraint, se-
curely replace the flap by pressing the
material firmly against the seat.
REAR-FACING CHILD RESTRAINT
INSTALLATION USING THE SEAT
BELTS
WARNING
The three-point seat belt with Auto-
matic 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, 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.

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.FORWARD-FACING CHILD

• Make sure the child’s head will be properlysupported 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 recom-
mended 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
All booster seats should be installed in
the rear seat. However, if you must in-
stall a booster seat in the front passen-
ger seat, move the passenger's seat to
the rearmost position.
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. 1-43) before installing a child
restraint. Follow these steps to install a booster seat
