2023 NISSAN SENTRA ECU

WARNING
• Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and re-
ceive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries. •
For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat properly. For additional infor-
mation, see “Precautions on seat belt
usage” (P. 1-12).
•
Af ter adjustment, gently rock in the
seat to make sure it is securely locked.
• Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents.
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
• Do not adjust the driver’s seat while
driving so full attention may be given
to vehicle operation. The seat may
move suddenly and could cause loss
of control of the vehicle.
•
The seatback should not be reclined
any more than needed for comfort.
Seat belts are most effective when the
passenger sits well back and straight
up in the seat. If the seatback is re-
clined, the risk of sliding under the lap
belt and being injured is increased.

FOLDING REAR SEAT
Pull the knobOAto fold each seatback
down.
WARNING
• Never allow anyone to ride in the
cargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop. •
Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.
CENTER ARMREST (if so equipped)

WARNING
Head restraints/headrests supplement
the other vehicle safety systems. They
may provide additional protection
against injury in certain rear end colli-
sions. Adjustable head restraints/
headrests must be adjusted properly,
as specified in this section. Check the
adjustment af ter someone else uses
the seat. Do not attach anything to the
head restraint/headrest stalks or re-
move the head restraint/headrest. Do
not use the seat if the head restraint/
headrest has been removed. If the head
restraint/headrest was removed, rein-
stall and properly adjust the head
restraint/headrest before an occupant
uses the seating position. Failure to fol-
low these instructions can reduce the
effectiveness of the head restraints/
headrests. This may increase the risk of
serious injury or death in a collision.
The illustration shows the seating positions
equipped with head restraints/headrests.
 Indicates the seating position is
equipped with a head restraint.
 Indicates the seating position is
equipped with a headrest.
+ Indicates the seating position is not
equipped with a head restraint or headrest
(if applicable).
• Your vehicle is equipped with a head restraint/headrest that may be inte-
grated, adjustable or non-adjustable. • Adjustable head restraints/headrests
have multiple notches along the stalk(s)
to lock them in a desired adjustment
position.
• The non-adjustable head restraints/ headrests have a single locking notch to
secure them to the seat frame.
• Proper Adjustment: – For the adjustable type, align the headrestraint/headrest so the center of
your ear is approximately level with the
center of the head restraint/headrest.
– If your ear position is still higher than the recommended alignment, place
the head restraint/headrest at the
highest position.
• If the head restraint/headrest has been removed, ensure that it is reinstalled and
locked in place before riding in that des-
ignated seating position.

SEAT BELT WARNING LIGHT AND
CHIME
The driver and front passenger seat is
equipped with an enhanced seat belt re-
minder function. If your vehicle is equipped
with an enhanced seat belt reminder func-
tion, a visual and audible alert will operate if
a driver or front passenger seat belt is un-
buckled at speeds of approximately 9 mph
(15 km/h) or more under the following con-
ditions:
• If the driver seat belt is not fastened.• The front passenger’s seat belt is not fas-
tened and the seat is occupied by a pas-
senger for 7 seconds af ter the ignition
switch is placed in the ON position.
• The front passenger’s seat belt is not fas- tened and objects or external force on
the passenger seat change the seat belt
reminder classification to Occupied.
The seat belt warning light will flash under
the conditions shown above until the nec-
essary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 90 seconds or until one of the fol-
lowing conditions is met:
• The unbuckled front occupant’s seat belt is securely fastened.
• The seat belt reminder function in the front passenger seat no longer detects
that the front passenger seat is occupied.
• The ignition is turned off or the vehicle is placed in P (Park).
The below situations could result in the
seat belt reminder light being illuminated
and the chime sounding, even with no oc-
cupant present in the passenger seat:
• Heavy objects placed on the seat.
• Someone pushing or pulling on the front passenger seat. • An object placed under the front passen-
ger seat.
• An object placed between the seat cush- ion and center console or between the
seat cushion and the door.
• An object hanging on the seat or placed in the seatback pocket.
• A child restraint or other object pressing against the rear of the seatback.
NOTE:
The rear seats are equipped with a seat
belt warning message in the vehicle in-
formation display.
For additional information, see “Vehicle in-
formation display 4.2 inch (11 cm) TYPE A”
(P. 2-18) or “Vehicle information display
7 inch (18 cm) TYPE B” (P. 2-32).
PREGNANT WOMEN
NISSAN recommends that pregnant
women use seat belts. The seat belt should
be worn snug and always position the lap
belt as low as possible around the hips, not
the waist. Place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific
recommendations.

3. Position the lap belt portionlow and
snug on the hips
OBas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
OC.Be
sure the shoulder belt is routed over
your shoulder and across your chest.
The front passenger seat and the rear
seating positions’ three-point seat belts
have two modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR) The ELR mode allows the seat belt to ex-
tend and retract to allow the driver and
passengers some freedom of movement
in the seat. The ELR locks the seat belt
when the vehicle slows down rapidly or
during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the
seat belt tongue is detached from the
buckle and fully retracted. The seat belt re-
turns to the ELR mode af ter the seat belt
fully retracts. For additional information,
see “Child restraints” (P. 1-23).
The ALR mode should be used only for
child restraint installation. During nor-
mal seat belt use by an occupant, the
ALR mode should not be activated. If it is
activated, it may cause uncomfortable
seat belt tension. It can also change
the operation of the front passenger
air bag. For additional information, see
“Front passenger air bag and status
light” (P. 1-55).
WARNING
When fastening the seat belts, be cer-
tain that the seatbacks are completely
secured in the latched position. If they
are not completely secured, passen-
gers may be injured in an accident or
sudden stop.
LRS2675
1-18Safety-Seats, seat belts and supplemental restraint system

WARNING
• Af ter adjustment, release the adjust-
ment button and try to move the
shoulder belt anchor up and down
to make sure it is securely fixed in
position.
• The shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may re-
duce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/
shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available for purchase. The ex-
tender adds approximately 8 in (200 mm)
of length and may be used for either the
driver or front passenger seating position.
It is recommended that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
• Only NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
• Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal injury
in the event of an accident.
• Never use seat belt extenders to in-
stall child restraints. If the child re-
straint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
• To clean the seat belt webbing, apply a
mild soap solution or any solution rec-
ommended for cleaning upholstery or
carpet. Then wipe with a cloth and allow
the seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry. •
If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der belt guide with a clean, dry cloth.
• Periodically check to see that the seat
belt and the metal components, such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.
1-20Safety-Seats, seat belts and supplemental restraint system

WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes
tight. This can occur even if the vehicle
is parked. Unbuckle the seat belt to re-
lease the child. If the seat belt cannot
be unbuckled or is already unbuckled,
release the child by cutting the seat
belt with a suitable tool (such as a knife
or scissors) to release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in
this manual, child safety information is
available from many other sources, includ-
ing doctors, teachers, government traffic
safety offices, and community organiza-
tions. Every child is different, so be sure to
learn the best way to transport your child.
There are three basic types of child re-
straint systems:
• Rear-facing child restraints • Forward-facing child restraints
• Booster seats
The proper restraint depends on the child's
size. Generally, infants up to about 1 year
and less than 20 lbs. (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for chil-
dren who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle
lap/shoulder belt on a child who can no
longer use a forward-facing child restraint.
WARNING
Infants and children need special pro-
tection. The vehicle's seat belts may
not fit them properly. The shoulder belt
may come too close to the face or neck.
The lap belt may not fit over their small
hip bones. In an accident, an improp-
erly fitting seat belt could cause serious
or fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children.
For additional information, see “Child re-
straints” (P. 1-23). A child restraint may be secured in the ve-
hicle by using either the LATCH (Lower An-
chors and Tethers for CHildren) system or
with the vehicle seat belt. For additional
information, see “Child restraints” (P. 1-23).
NISSAN recommends that all pre-teens
and children be restrained in the rear
seat. Studies show that children are
safer when properly restrained in the
rear seat than in the front seat.
This is especially important because
your vehicle has a supplemental re-
straint system (air bag system) for the
front passenger. For additional informa-
tion, see “Supplemental Restraint Sys-
tem (SRS)” (P. 1-44).
INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
NISSAN recommends that infants be
placed in child restraints that comply with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.
You should choose a child restraint that fits
your vehicle and always follow the manu-
facturer's instructions for installation and
use.
