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

BOOSTER SEATS
For additional information on installing a
booster seat in your vehicle, follow the in-
structions outlined in this section.
Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured or killed in a sudden stop or col-
lision greatly increases:
– Make sure the shoulder portion of
the belt is away from the child's face
and neck and the lap portion of the
belt does not cross the stomach.
– Make sure the shoulder belt is not
behind the child or under the child's
arm.
– A booster seat must only be installed
in a seating position that has a lap/
shoulder belt. Booster seats of various sizes are offered
by several manufacturers. When selecting
any booster seat, keep the following points
in mind:
• Choose only a booster seat with a label
certif ying that it complies with Federal
Motor Vehicle Safety Standard 213 or Ca-
nadian Motor Vehicle Safety Standard 213.
• Check the booster seat in your vehicle to be sure it is compatible with the vehicle’s
seat and seat belt system.

Safety-Seats, seat belts and supplemental restraint system1-43

• 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.
Booster seat installation
WARNING
All booster seats should be installed in
the rear seat. However, if you must in-
stall a booster seat in the front passen-
ger seat, move the passenger's seat to
the rearmost position.
To avoid injury to child, do not use the
lap/shoulder belt in the Automatic
Locking Retractor (ALR) mode when us-
ing a booster seat with the seat belts.
For additional information, see all Warnings
and Cautions in the “Child safety” (P. 1-21),
“Child restraints” (P. 1-23) and “Booster
seats” (P. 1-43) before installing a child
restraint. Follow these steps to install a booster seat
in the rear seat or in 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
high back 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
information about head restraint/
headrest adjustment, removal and in-
stallation, see "Head restraints/
headrests" (P. 1-8). 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” (P. 1-15). 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, see
“Front passenger air bag and status
light” (P. 1-57).

PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
• Driver and front passenger supplementalfront-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
• Roof-mounted curtain side-impact and rollover supplemental air bag
• Driver and front passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front and rear outboard seats)
Supplemental front-impact air bag
system
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. 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
impacted.
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 outboard
seat passengers in certain side-impact
collisions. The side air bags are designed to
inflate on the side where the vehicle is
impacted.
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.Driver and front passenger supplemen-
tal knee air bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.
The SRS is designed to
supplementthe
crash protection provided by the driver and
front passenger and rear seat belts and is
not a substitute for them. Seat belts
should always be correctly worn and the
occupant seated a suitable distance away
from the steering wheel, instrument panel
and door finishers. For additional informa-
tion, see “Seat belts” (P. 1-12).
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.
SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
Safety-Seats, seat belts and supplemental restraint system1-47

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 front
passenger knee air bag will not in-
flate if the passenger air bag status
light is lit. For additional information,
see “Front passenger air bag and sta-
tus light” (P. 1-57). •
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 Ad-
vanced Air Bag System, if you are un-
restrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also re-
ceive 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, see “Front passenger air bag
and status light” (P. 1-57).
• 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.
