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.

Safety—Seats, seat belts and supplemental restraint system1-19

All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. For
additional information, refer to “Child re-
straints” in this section.
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, 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 re-
straint system (air bag system) for the
front passenger. For additional informa-
tion, 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 recommends that infants be
placed in child restraints that comply with
Federal Motor Vehicle Safety Standards orCanadian 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.
SMALL CHILDREN
Children that are over 1 year old and weigh
at least 20 lbs. (9 kg) should remain in a
rear-facing child restraint as long as pos-
sible up to the height or weight limit of the
child restraint. Children who outgrow the
height or weight limit of the rear-facing
child restraint and are at least 1 year old
should be secured in a forward-facing child
restraint with a harness. Refer to the manu-
facturer’s instructions for minimum and
maximum weight and height recommen-
dations. NISSAN recommends that small
children 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 al-
ways follow the manufacturer’s instruc-
tions for installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they
reach the maximum height or weight limit
allowed by the child restraint manufac-
turer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-
facing child restraint, NISSAN recommends
that the child be placed in a commercially
available booster seat to obtain proper
seat belt fit. For a seat belt to fit properly, the
booster seat should raise the child so that
the shoulder belt is properly positioned
across the chest and the top, middle por-
tion of the shoulder. The shoulder belt
should not cross the neck or face and
should not fall off the shoulder. The lap belt
should lie snugly across the lower hips or
upper thighs, not the abdomen. A booster
seat can only be used in seating positions
that have a three-point type seat belt. The
booster seat should fit the vehicle seat and
have a label certif ying that it complies with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.
Safety—Seats, seat belts and supplemental restraint system1-21

– Child restraint anchorages are de-signed to withstand only those
loads imposed by correctly fitted
child restraints. Under no circum-
stances 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 re-
straint anchorages. The child re-
straint will not be properly in-
stalled using the damaged
anchorage, and a child could be se-
riously injured or killed in a
collision.
– Never use the anchor points for adult seat belts, or other items.
– A child restraint with a top tether strap should not be used in the
front passenger seat.
– Keep seatbacks as upright as pos- sible af ter fitting the child
restraint.
– Infants and children should always be placed in an appropriate child
restraint while in the vehicle. ∙ When the child restraint is not in use,
keep it secured with the LATCH system
or a seat belt. In a sudden stop or col-
lision, loose objects can injure occu-
pants or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating
surface and buckles before placing a
child in the child restraint.
This vehicle is equipped with a universal
child restraint anchor system, referred to
as the LATCH (Lower Anchors and Tethers
for CHildren) system. Some child restraints
include rigid or webbing-mounted attach-
ments that can be connected to these an-
chors. For additional information, refer to
“LATCH (Lower Anchors and Tethers for
CHildren) system” in this section.
If you do not have a LATCH compatible
child restraint, the vehicle seat belts can be
used.
Several manufacturers offer child re-
straints for infants and children of various
sizes. When selecting any child restraint,
keep the following points in mind: ∙ Choose only a restraint with a label cer-
tif ying that it complies with Federal Mo-
tor Vehicle Safety Standard 213 or Cana-
dian Motor Vehicle Safety Standard 213.
∙ Check the child restraint in your vehicle to be sure it is compatible with the vehi-
cle’s seat and seat belt system.
∙ If the child restraint is compatible with your vehicle, place your child in the child
restraint and check the various adjust-
ments to be sure the child restraint is
compatible with your child. Choose a
child restraint that is designed for your
child’s height and weight. Always follow
all recommended procedures.
∙ If the combined weight of the child and child restraint is less than 65 lbs.
(29.5 kg), you may use either the LATCH
anchors or the seat belt to install the
child restraint (not both at the same
time).
∙ If the combined weight of the child and 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 restraintmanufacturer’s instructions for installa-
tion.
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. Canadian law re-
quires the top tether strap on forward-
facing child restraints be secured to the
designated anchor point on the vehicle.
LATCH (Lower Anchors and
Tethers for CHildren) SYSTEM
Your vehicle is equipped with special an-
chor points that are used with LATCH sys-
tem compatible child restraints. This sys-
tem may also be referred to as the ISOFIX
or ISOFIX compatible system. With this sys-
tem, you do not have to use a vehicle seat
belt to secure the child restraint unless the
combined weight of the child and child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and child restraint
is greater than 65 lbs. (29.5 kg), use the ve-
hicle’s seat belt (not the lower anchors) to install the child restraint. Be sure to follow
the child restraint manufacturer’s instruc-
tions for installation.
The LATCH anchor points are provided to
install child restraints in the rear outboard
seating positions only. Do not attempt to
install a child restraint in the center position
using the LATCH anchors.

WARNING
Failure to follow the warnings and in-
structions for proper use and installa-
tion of child restraints could result in
serious injury or death of a child or
other passengers in a sudden stop or
collision:
– Attach LATCH system compatiblechild restraints only at the loca-
tions shown in the illustration.
– Do not secure a child restraint in the center rear seating position us-
ing the LATCH lower anchors. The
child restraint will not be secured
properly.

– Inspect the lower anchors by in-serting your fingers into the lower
anchor area. Feel to make sure
there are no obstructions over the
anchors such as seat belt webbing
or seat cushion material. The child
restraint will not be secured prop-
erly if the lower anchors are
obstructed.
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 re-
straint will not be properly installed us-
ing the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

lower anchor attachments
LATCH compatible child restraints include
two rigid or webbing-mounted attach-
ments that can be connected to two an-
chors located at certain seating positions
in your vehicle. With this system, you do not
have to use a vehicle seat belt to secure the
child restraint. Check your child restraint for
a label stating that it is compatible with
LATCH. This information may also be in the
instructions provided by the child restraint
manufacturer.

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 rear-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 an-
chors. Check to make sure the LATCH
attachment is properly attached to the
lower anchors.

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
seatback 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
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.
