restraint and insert it into the buckle until you
hear and feel the latch engage. Be sure to
follow the child restraint manufacturer’s in-
structions for belt routing.3. Pull the shoulder belt until the belt is fully
extended. At this time, the seat belt retractor
is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . It reverts to the
Emergency Locking Retractor (ELR) mode
when the seat belt is fully retracted.4. Allow the seat belt to retract. Pull up on the
shoulder belt to remove any slack in the belt.

5. Remove any additional slack from the child
restraint; press downward and rearward
firmly in the center of the child restraint to
compress the vehicle seat cushion and seat-
back while pulling up on the seat belt.6. 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.7. 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 seat
belt webbing out of the retractor, the retrac-
tor is in the ALR mode.
8. Check to make sure that the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 3
through 7.
After the child restraint is removed and the seat
belt fully retracted, the ALR mode (child restraint
mode) is canceled.

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,

Repair and replacement procedure
The front air bags, side air bags, curtain air bags
and pretensioners are designed to inflate on a
one-time-only basis. As a reminder, unless it is
damaged, the supplemental air bag warning light
remains illuminated after inflation has occurred.
Repair and replacement of these supplemental
air bag systems should be done only by a
NISSAN dealer.
When maintenance work is required on the ve-
hicle, the front air bags, side air bags, curtain air
bags, pretensioners and related parts should be
pointed out to the person performing the mainte-
nance. The ignition switch should always be
placed in the LOCK position when working under
the hood or inside the vehicle.
WARNING
●Once a front air bag, side air bag, or
curtain air bag has inflated, the air bag
module will not function again and
must be replaced. Additionally, if any of
the front air bags inflate, the activated
pretensioner must also be replaced.
The air bag module and pretensioner
should be replaced by a NISSAN dealer.
The air bag module and pretensioner
cannot be repaired.●The front air bag, side air bag, curtain
air bag systems and the pretensioner
system should be inspected by a
NISSAN dealer if there is any damage to
the front end or side portion of the
vehicle.
●If you need to dispose of the supple-
mental air bag or pretensioner systems
or scrap the vehicle, contact a NISSAN
dealer. Correct air bag and pretensioner
system disposal procedures are set
forth in the appropriate NISSAN Service
Manual. Incorrect disposal procedures
could cause personal injury.
