NISSAN SENTRA 2023 Repair Manual

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, 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. 1-16).

7. If the booster seat is installed in the frontpassenger 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. 1-55).
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 front passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front seats 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 supple-
mental 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 seat
passengers in certain side-impact colli-
sions. The side air bags are designed to
inflate on the side where the vehicle is
impacted.
Driver and front passenger supplemen-
tal 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.

SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
1-44Safety-Seats, seat belts and supplemental restraint system

The SRS is designed tosupplementthe
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, 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.
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 supplemental knee air bag
will not inflate if the passenger air bag
status light is lit. For additional infor-
mation, see “Front passenger air bag
and status light” (P. 1-55).

•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 front
passenger supplemental 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 information,
see “Front passenger air bag and
status light” (P. 1-55).
• 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.

• Never let children ride unrestrained
or extend their hands or face out of
the window. Do not attempt to hold
them in your lap or arms. Some ex-

WARNING
• Children may be severely injured or
killed when the front air bags, side
air bags or curtain air bags inflate if
they are not properly restrained.
Pre-teens and children should be
properly restrained in the rear seat, if
possible.

WARNING
• Even with the NISSAN Advanced Air
Bag System, never install a rear-
facing child restraint in the front seat.
An inflating front air bag could seri-
ously injure or kill your child. For
additional information, see “Child
restraints” (P. 1-23).WARNING
Front seat-mounted side-impact sup-
plemental air bags and roof-mounted
curtain side-impact and rollover supple-
mental air bags:
• The side air bags and curtain air bags
ordinarily will not inflate in the event
of a frontal impact, rear impact, or
lower severity side collision. Always
wear your seat belts to help reduce
the risk or severity of injury in various
kinds of accidents.

WARNING
• The seat belts, the side air bags and
curtain air bags are most effective
when you are sitting well back and up-
right in the seat with both feet on the
floor. The side air bag and curtain air
bag inflate with great force. Do not
allow anyone to place their hand,
leg or face near the side air bag on the
side of the seatback of the front
seat or near the side roof rails. Do not
allow anyone sitting in the front seats
or rear outboard seats to extend their
hand out of the window or lean
against the door. Some examples of
dangerous riding positions are shown
in the previous illustrations.
WARNING
•
When sitting in the rear seat, do not
hold onto the seatback of the front
seat. If the side air bag inflates, you
may be seriously injured. Be especially
careful with children, who should al-
ways be properly restrained. Some ex-
amples of dangerous riding positions
are shown in the illustrations.
• Do not use seat covers on the front
seatbacks. They may interfere with
side air bag inflation.
