Nissan Sentra (2019 year). Instruction - part 4

Do not install child restraints that re-
quire the use of a top tether strap in
seating positions that do not have a
top tether anchor.

4. Pull the shoulder belt until the belt is

fully extended. At this time, the seat belt
retractor is in the ALR mode (child re-
straint mode). It reverts to ELR mode
when the seat belt is fully retracted.

5. Allow the seat belt to retract. Pull up on

the shoulder belt to remove any slack
in the belt.

6. Remove any additional slack from the

seat belt; press downward and rear-
ward 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. Tighten the tether strap according to

the manufacturer’s instructions to re-
move any slack.

8. After attaching the child restraint, test

it before you place the child in it. Push it
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 re-
straint 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.

Safety—Seats, seat belts and supplemental restraint system

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 re-
straint will not be properly installed us-
ing the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

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 in-

stalled in a seating position that
has a lap/shoulder belt.

Low back booster seat

High back booster seat

LRS2479

Safety—Seats, seat belts and supplemental restraint system

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

certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.

∙ Check the booster seat in your vehicle

to be sure it is compatible with the vehi-
cle’s seat and seat belt system.

∙ Make sure the child’s head will be prop-

erly supported 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 ad-
justments to be sure the booster seat is
compatible with the child. Always follow
all recommended 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

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, refer to all Warn-
ings and Cautions in the “Child safety”,
“Child restraints” and “Booster seats” sec-
tions of this manual before installing a child
restraint.

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
rearmost position.

2. Position the booster seat on the seat.

Only place it in a front-facing direction.
Always follow the booster seat manu-
facturer’s instructions.

3. The booster seat should be positioned

on the vehicle seat so that it is stable.

If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect 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 ad-
ditional information, 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 manu-
facturer’s instructions for adjusting the
seat belt routing.

5. Pull the shoulder belt portion of the

seat belt toward the retractor to take
up extra slack. Be sure the shoulder
belt is positioned across the top,
middle portion of the child’s shoulder.
Be sure to follow the booster seat
manufacturer’s instructions for adjust-
ing 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.

PRECAUTIONS ON SRS

This SRS section contains important infor-
mation concerning the following systems:

∙ Driver and front passenger supplemen-

tal front-impact air bag (NISSAN Ad-
vanced Air Bag System)

∙ Front

seat-mounted

side-impact

supplemental air bag

∙ Roof-mounted curtain side-impact and

rollover supplemental air bag

∙ Seat belt with pretensioner(s) (front

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.

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.

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 supplement the
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.

After 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
after about 7 seconds if the system is
operational.

SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)

1-44

Safety—Seats, seat belts and supplemental restraint system

WARNING

∙ The front air bags ordinarily will not

inflate in the event of a side impact,
rear impact, rollover, or lower severity
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 will not

inflate if the passenger air bag status
light is lit. For additional information,
refer to “Front passenger air bag and
status 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 in-
flates the air bags as needed. Failure
to properly wear seat belts can in-
crease 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 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 informa-
tion, 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.

WARNING

∙ The seat belts, the side air bags and

curtain air bags are most effective
when you are sitting well back and
upright 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 espe-
cially

careful

with

children,

who

should always be properly restrained.

WARNING

To ensure proper operation of the pas-
senger’s NISSAN Advanced Air bag Sys-
tem,

please

observe

the

following

items.

∙ Do not allow a passenger in the rear

seat to push or pull on the seatback
pocket.

∙ Do not place heavy loads heavier than

9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.

∙ Make sure that there is nothing press-

ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.

∙ Make sure that there is no object

placed under the front passenger
seat.

∙ Make sure that there is no object

placed between the seat cushion and
center console or between the seat
cushion and the door.

∙ If a forward-facing child restraint is

installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. For additional in-
formation, refer to “Child restraints” in
this section.

∙ Confirm the operating condition with

the front passenger air bag status
light.

∙ If you notice that the front passenger

air bag status light is not operating as
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service.

∙ Until you have confirmed with a

dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.

∙ Do not position the front passenger

seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.

This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. All of the information, cautions
and warnings in this manual must be fol-
lowed.

The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they

1-52

Safety—Seats, seat belts and supplemental restraint system

may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.

The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU). Infla-
tor operation is based on the severity of a
collision and seat belt usage for the driver.
For the front passenger, the occupant clas-
sification sensor is also monitored. Based
on information from the sensor, only one
front air bag may inflate in a crash, depend-
ing on the crash severity and whether the
front occupants are belted or unbelted. Ad-
ditionally, the front passenger air bag may
be automatically turned off under some
conditions, depending on the weight de-
tected on the front passenger seat and
how the seat belt is used. If the front pas-
senger air bag is OFF, the passenger air
bag status light will be illuminated. For ad-
ditional information, refer to “Front passen-
ger air bag and status light” in this section.
One front air bag inflating does not indicate
improper performance of the system.

If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact NISSAN. Con-
tact information is contained in the front of
this Owner’s Manual.

When a front air bag inflates, a fairly loud
noise may be heard, followed by the re-
lease of smoke. This smoke is not harmful
and does not indicate a fire. Care should be
taken to not inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.

Front air bags, along with the use of seat
belts, help to cushion the impact force on
the face and chest of the front occupants.
They can help save lives and reduce seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.

Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front passenger seated upright
as far as practical away from the steering
wheel or instrument panel. The front air

bags inflate quickly in order to help protect
the front occupants. Because of this, the
force of the front air bag inflating can in-
crease the risk of injury if the occupant is
too close to, or is against, the front air bag
module during inflation.

The front air bags deflate quickly after a
collision.

The front air bags operate only when the
ignition switch is placed in the ON posi-
tion.
