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, refer to “Precau-
tions on seat belt usage” in this section. To
adjust, pull out the adjustment button
O1
and move the shoulder belt anchor to the
desired position
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 ad-
justment button to lock the shoulder belt
anchor into position.
WRS0139LRS0242

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.

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 manufacturer's instruc-
tions 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 possible up
to the height or weight limit of the child re-
straint. 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 har-
ness. Refer to the manufacturer’s instruc-
tions for minimum and maximum weight
and height recommendations. NISSAN rec-
ommends that small children be placed in
child restraints that comply with Federal Mo-
tor Vehicle Safety Standards or Canadian
Motor Vehicle Safety Standards. You should
choose a child restraint that fits your vehicle
and always follow the manufacturer’s in-
structions 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.A booster seat should be used until the
child can pass the seat belt fit test below:
• Are the child’s back and hips against the
vehicle seatback?
• Is the child able to sit without slouching?
• Do the child’s knees bend easily over the front edge of the seat with feet flat on the
floor?
• Can the child safely wear the seat belt (lap belt low and snug across the hips and
shoulder belt across mid-chest and
shoulder)?
• Is the child able to use the properly ad- justed head restraint/headrest?
• Will the child be able to stay in position for the entire ride?
1-22Safety-Seats, seat belts and supplemental restraint system

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 certi-f ying that it complies with Federal Motor
Vehicle Safety Standard 213 or Canadian
Motor Vehicle Safety Standard 213.
• Check the child restraint in your vehicle to be sure it is compatible with the vehicle'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 re-
straint.
• Be sure to follow the child restraint manufacturer’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 vehi-
cle’s seat belt (not the lower anchors) to

–Suspension parts other than
those designated as Genuine
NISSAN parts are used. (If the ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect an obstacle
correctly.)
• Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Sys-
tem fault” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them.

O1Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de- signed for passenger vehicles (not
all tires have this information).
2. Three-digit number (215): This number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge. 3. Two-digit number (65): This num-
ber, known as the aspect ratio,
gives the tire's ratio of height to
width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This num- ber is the wheel or rim diameter in
inches. 6. Two- or three-digit number (95):
This number is the tire's load in-
dex. It is a measurement of how
much weight each tire can sup-
port. You may not find this infor-
mation on all tires because it is
not required by law.
7. H: Tire speed rating. You should not drive the vehicle faster than
the tire speed rating.
