lock NISSAN SENTRA 2009 Owner´s Manual

The Emergency Locking Retractor (ELR) mode
allows the seat belt to extend 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 Automatic Locking Retractor (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 returns to the ELR mode
after the seat belt fully retracts. See “Child re-
straints” later in this section for more information.
The ALR mode should be used only for
child restraint installation. During normal
seat belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt ten-
sion. It can also change the operation of
the front passenger air bag. See “Front
passenger air bag and status light” later in
this section.WARNING
When fastening the seat belts, be certain
that the seatbacks are completely se-
cured in the latched position. If they are
not completely secured, passengers may
be injured in an accident or sudden stop.
Unfastening the seat belts
1To unfasten the seat belt, press the button on
the buckle. The seat belt automatically re-
tracts.
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 or
if you have any questions about seat belt opera-
tion, see a NISSAN dealer.
Center of the rear seat (except SE-R
model)
The rear seat center seat belt has a connector
tongue
1and a seat belt tongue2. Both the
connector tongue and the seat belt tongue must
be securely latched for proper seat belt opera-
tion.
WARNING
●Always fasten the connector tongue
and the seat belt in the order shown.
●Always make sure both the connector
tongue and the seat belt tongue are
secured when using the seat belt or
installing a child restraint. Do not use
the seat belt or child restraint with only
the seat belt tongue attached. This
could result in serious personal injury in
case of an accident or a sudden stop.

SHOULDER BELT HEIGHT
ADJUSTMENT (front seats)
The shoulder belt anchor height should be ad-
justed to the position best for you. (See “Precau-
tions on seat belt usage” earlier in this section.)
To adjust, pull out the adjustment button
1and
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 adjustment button to lock the shoul-
der belt anchor into position.
WARNING
●After adjustment, release the adjust-
ment button and try to move the shoul-
der 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 reduce the effec-
tiveness 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 is available which is
compatible with the installed seat belts. The ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver or
front passenger seating position. See a NISSAN
dealer for assistance 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 install
child restraints. If the child restraint is
not secured properly, the child could be
seriously injured in a collision or a sud-
den stop.
SEAT BELT MAINTENANCE
●To clean the seat belt webbing,apply a
mild soap solution or any solution recom-
mended 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
guideof 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 as-
sembly should be replaced.

properly secured prior to each use. If the
child restraint is loose, repeat steps 2
through 4.
CHILD RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
●Even with the NISSAN Advanced Air
Bag System, never install a rear-facing
child restraint in the front passenger
seat. Front air bags inflate with great
force. A rear-facing child restraint could
be struck by the front air bag in a crash
and could seriously injure or kill your
child.●NISSAN recommends that child re-
straints be installed in the rear seat.
However, if you must install a front-
facing child restraint in the front pas-
senger seat, move the passenger seat
to the rearmost position. Also, be sure
the front passenger air bag status light
is illuminated to indicate the passenger
air bag is OFF. See “Front passenger air
bag and status light” later in this sec-
tion for details
●The three-point seat belt in your vehicle
is equipped with an Automatic Locking
Retractor (ALR) which 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
otherwise be unsecured and cause in-
jury to the child in a sudden stop or
collision. Also, it can change the opera-
tion of the front passenger air bag. See
“Front passenger air bag and status
light” later in this section.

6. Remove any additional slack from the seat
belt; press downward and rearward firmly in
the center of the child restraint with your
knee to compress the vehicle seat cushion
and seatback while pulling up on the seat
belt.7. If the child restraint is equipped with a top
tether strap, route the top tether strap and
secure the tether strap to the tether anchor
point (rear seat installation only) . See “Top
tether strap child restraint” in this section.
Do not install child restraints that require the
use of a top tether strap to seating positions
that do not have a top tether anchor.8. After attaching the child restraint, test it be-
fore you place the child in it. Push it from side
to side while holding the seat near the seat
belt 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 belt holds the restraint in place. If the
restraint is not secure, tighten the belt as
necessary, or put the restraint in another
seat and test it again. You may need to try a
different child restraint. Not all child re-
straints fit in all types of vehicles.
9. Check that the retractor is in the ALR mode
by trying to pull more seat belt out of the
retractor. If you cannot pull any more belt
webbing out of the retractor, the retractor is
in the ALR mode.
10. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 3
through 8.

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 vehicle 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
NISSAN recommends that booster seats
be installed in the rear seat. However, if
you must install a booster seat in the front
passenger seat, move the passenger’s
seat to the rearmost position.
CAUTION
Do not use the lap/shoulder belt Auto-
matic Locking Retractor mode when using
a booster seat with the seat belts.
Follow these steps to install a booster seat in the
rear seat or in the front passenger seat:1.If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only
place it in a front-facing direction. Always
follow the booster seat manufacturer’s in-
structions.

tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . Based on the
weight on the seat detected by the occupant
classification sensor and the belt tension de-
tected on the seat belt, the Advanced Air Bag
System determines whether the front passenger
air bag should be automatically turned OFF as
required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger air bag to be automatically turned OFF. For
small adults it may be turned OFF, however if the
occupant takes his/her weight off the seat cush-
ion (for example, by not sitting upright, by sitting
on an edge of the seat, or by otherwise being out
of position) , this could cause the sensor to turn
the air bag OFF. In addition, if the occupant
improperly uses the seat belt in the ALR mode
(child restraint mode) , this could cause the air
bag to be turned OFF. Always be sure to beseated and wearing the seat belt properly for the
most effective protection by the seat belt and
supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the ALR mode (child restraint mode) may
allow the restraint to tip or move in an accident or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. See “Child restraints” earlier in this section
for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object’s weight detected by the occupant
classification sensor. Other conditions could also
result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.Using the passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the passen-
ger air bag status light is illuminated (indicating
that the air bag is OFF) , it could be that the
person is a small adult, or is not sitting on the seat
properly or not using the seat belt properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may not
be illuminated, depending on the size of the child
and the type of child restraint being used. If the air
bag status light is not illuminated (indicating that
the air bag might inflate in a crash) , it could be
that the child restraint or seat belt is not being
used properly. Make sure that the child restraint is
installed properly, the seat belt is used properly
and the occupant is positioned properly. If the air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF) . Your NISSAN dealer can check that the
system is OFF by using a special tool. However,
