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
• 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 shoul-
der 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 dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.

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
manufacturer.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, see
“LATCH (Lower Anchors and Tethers for
CHildren) system” (P. 1-25).
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
restraint.
• Be sure to follow the child restraint manufacturer’s instructions for
installation.
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

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The BSW system cannot detect all ve-
hicles under all conditions.
• The radar sensors may not be able to
detect and activate BSW when cer-
tain objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec-
tion zone when you accelerate
from a stop.
– A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly
from behind.
– A vehicle which your vehicle over-
takes rapidly. –
A vehicle that passes through the
detection zone quickly.
– When overtaking several vehicles
in a row, the vehicles af ter the first
vehicle may not be detected if
they are traveling close together.
• The radar sensors’ detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sen-
sors may detect vehicles driving two
lanes away.
• The radar sensors are designed to ig-
nore most stationary objects; how-
ever, objects such as guardrails,
walls, foliage and parked vehicles
may occasionally be detected. This is
a normal operation condition.
• The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on
the vehicle •
Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
• Excessive noise (for example, audio
system volume, open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.
Starting and driving5-51

•Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep
hill.
– The vehicle’s posture is changed
(e.g., when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by
turning the steering wheel fully.
– Snow chains are used. –
Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started.
– The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.
– The vehicle is towing an object (if
so equipped). –
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.)
– If the vehicle is using an accessory
like a bike rack, or cargo carrier
that blocks the sensors.
• Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
Starting and driving5-133

–When your vehicle or the vehicle
or pedestrian ahead moves
quickly or significantly such that
the system cannot detect and re-
act in time (for example, pedes-
trian moving quickly toward the
vehicle at close range, vehicle cut-
ting in, changing lanes, making a
turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is
offset from the vehicle’s forward
path.
– If the speed difference between
the two vehicles is small.
– The pedestrian’s profile is par-
tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
– There is poor contrast of a person
to the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds af-
ter starting the engine. –
If the vehicle ahead has a unique
or unusual shape, extremely low
or high clearance heights, or un-
usual cargo loading or is narrow
(for example, a motorcycle).
– When the vehicle or pedestrian is
located near a traffic sign, a reflec-
tive area (for example, water on
road), or is in a shadow.
– When multiple pedestrians are
grouped together.
– When the view of the pedestrian is
obscured by a vehicle or other
object.
– While towing a trailer or other
vehicle.
• The system performance may be de-
graded in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is
loaded in the rear seat or the
cargo area of your vehicle.
• The system is designed to automati-
cally check the sensor’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect some forms of obstruction of the
sensor area such as ice, snow or stickers, for example. In these cases,
the system may not be able to warn
the driver properly. Be sure that you
check, clean and clear sensor areas
regularly.
• In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
• The AEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of ve-
hicles or pedestrians, or if they are
the same size and position as a ve-
hicle or motorcycle’s tail lights.
• The system may keep operating
when the vehicle ahead is turning
right or lef t.
• The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
•
Depending on the road shape (curved
road, entrance and exit of the curve,
winding road, lane regulation, under
construction, etc.), the system may
operate temporarily for the oncoming
vehicle in front of your vehicle.
