from side to side while holding the child
restraint 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 seat
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 restraints fit in all types of
vehicles. 9. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 2
through 8.
10. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should illuminate. If this light is not illu-
minated, refer to “Front passenger air
bag and status light” in this section.
Move the child restraint to another
seating position. Have the system
checked. It is recommended that you
visit a NISSAN dealer for this service.

WARNING
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
restraint will not be properly installed
using the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

Precautions on booster seats
LRS2479LRS0453

• Make sure the child’s head will be properlysupported by the booster seat or vehicle
seat. The seatback must be at or above
the center of the child’s ears. For example,
if a low back booster seat is chosen, the
vehicle seatback must be at or above the
center of the child’s ears. If the seatback is
lower than the center of the child’s ears, a
high back booster seat should be used.
• If the booster seat is compatible with your vehicle, place the child in the booster
seat and check the various adjustments
to be sure the booster seat is compatible
with the child. Always follow all recom-
mended procedures. 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.
The instructions in this section apply to
booster seat installation in the rear seats
or the front passenger seat.

3. The booster seat should be positionedon the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional infor-
mation, refer to “Head restraints/
headrests” in this section.

If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper booster
seat fit, try another seating position or a
different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure
to follow the booster seat manufactur-
er’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up ex-
tra slack. Be sure the shoulder belt is
positioned across the top, middle por-
tion of the child’s shoulder. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” in this section. 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in the ON position. The front passenger
air bag status light
may or may not
illuminate, depending on the size of the
child and the type of booster seat being
used. For additional information, refer to
“Front passenger air bag and status
light” in this section.
PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
• Driver and front passenger supplemental front-impact air bag (NISSAN Advanced
Air Bag System)
• Front seat-mounted side-impact supple- mental air bag
• Rear outboard seat-mounted side- impact supplemental air bag system
• Roof-mounted curtain side-impact and rollover supplemental air bag
• Driver and passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front seats and rear outboard seats)
Supplemental front-impact air bag sys-
tem
The NISSAN Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
LRS0865
SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)

Front seat-mounted side-impact
supplemental air bag system
This system can help cushion the impact
force to the chest area of the driver and
front passenger in certain side-impact col-
lisions. The side air bags are designed to
inflate on the side where the vehicle is im-
pacted.
Rear outboard seat-mounted side-
impact supplemental air bag system
This system can help cushion the impact
force to the chest area of the rear seat
passengers in certain side-impact colli-
sions. The side air bags are designed to
inflate on the side where the vehicle is im-
pacted.
Driver and passenger supplemental
knee air bag
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact
force to the head of occupants in front and
rear outboard seating positions in certain
side-impact collisions. The curtain air bags
are designed to inflate on the side where
the vehicle is impacted. In a rollover, the
curtain air bags are designed to inflate and
remain inflated for a short time.
The SRS is designed to
supplementthe
crash protection provided by the driver and
front passenger seat belts and is not a
substitute for them. Seat belts should al-
ways be correctly worn and the occupant
seated a suitable distance away from the
steering wheel, instrument panel and door
finishers. For additional information, refer
to “Seat belts” in this section. The supplemental air bags operate only
when the ignition switch is placed in the
ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
Safety-Seats, seat belts and supplemental restraint system1-45

WARNING
• The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity frontal collision. Always wear your
seat belts to help reduce the risk or
severity of injury in various kinds of
accidents
• The front passenger air bag and pas-
senger knee air bag will not inflate if
the passenger air bag status light is
lit. For additional information, refer
to “Front passenger air bag and sta-
tus light” in this section. •The seat belts and the front air bags
are most effective when you are sit-
ting well back and upright in the seat.
The front air bags inflate with great
force. Even with the NISSAN Advanced
Air Bag System, if you are unre-
strained, leaning forward, sitting side-
ways or out of position in any way, you
are at greater risk of injury or death in
a crash. You may also receive serious
or fatal injuries from the front air bag if
you are up against it when it inflates.
Always sit back against the seatback
and as far away as practical from the
steering wheel or instrument panel.
Always properly use the seat belts.
• The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The NISSAN Advanced Air
Bag System monitors the severity of
a collision and seat belt usage, then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
• The front passenger seat is equipped
with an occupant classification sen-
sor (weight sensor) that turns the
front passenger air bag and passen-
ger knee air bag OFF under some
conditions. This sensor is only used in
this seat. Failure to be properly
seated and wearing the seat belt can
increase the risk or severity of injury
in an accident. For additional infor-
mation, refer to “Front passenger air
bag and status light” in this section.
• Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could increase
the risk that they are injured when
the front air bag inflates.

are not properly restrained. Pre-
teens and children should be prop-
erly restrained in the rear seat, if
possible.
