ECU NISSAN SENTRA 2020 Owner´s Manual

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, refer to “Precautions on seat
belt usage” in this section.
• 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 reclined, the risk of sliding under
the lap belt and being injured is
increased.

•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 sud-
den 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)
Pull the armrest down as shown.
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.

• 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 po-
sition.
• 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.

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, re-
fer to “Child restraints” in this section.
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 ac-
tivated, it may cause uncomfortable seat
belt tension. It can also change the op-
eration of the front passenger air bag.
For additional information, refer to
“Front passenger air bag and status
light” in this section.
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.

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 re-
strained.
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, refer to “Child re-
straints” in this section.
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, refer to “Child restraints” in this
section.
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, refer to “Supplemental Restraint
System (SRS)” in this section.
CHILD SAFETY
Safety-Seats, seat belts and supplemental restraint system1-21

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 manufacturer's instruc-
tions for installation and use.
SMALL CHILDREN
Children that are over 1 year old and weigh at
least 20 lbs. (9 kg) should remain in a rear-
facing child restraint as long as possible up
to the height or weight limit of the child re-
straint. Children who outgrow the height or
weight limit of the rear-facing child restraint
and are at least 1 year old should be secured
in a forward-facing child restraint with a har-
ness. Refer to the manufacturer’s instruc-
tions for minimum and maximum weight
and height recommendations. NISSAN rec-
ommends that small children be placed in
child restraints that comply with Federal Mo-
tor Vehicle Safety Standards or Canadian
Motor Vehicle Safety Standards. You should
choose a child restraint that fits your vehicle
and always follow the manufacturer’s in-
structions for installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they
reach the maximum height or weight limit
allowed by the child restraint manufac-
turer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-
facing child restraint, NISSAN recommends
that the child be placed in a commercially
available booster seat to obtain proper
seat belt fit. For a seat belt to fit properly, the
booster seat should raise the child so that
the shoulder belt is properly positioned
across the chest and the top, middle por-
tion of the shoulder. The shoulder belt
should not cross the neck or face and
should not fall off the shoulder. The lap belt
should lie snugly across the lower hips or
upper thighs, not the abdomen. A booster
seat can only be used in seating positions
that have a three-point type seat belt. The
booster seat should fit the vehicle seat and
have a label certif ying that it complies with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.A booster seat should be used until the
child can pass the seat belt fit test below:
• Are the child’s back and hips against the
vehicle seatback?
• Is the child able to sit without slouching?
• Do the child’s knees bend easily over the front edge of the seat with feet flat on the
floor?
• Can the child safely wear the seat belt (lap belt low and snug across the hips and
shoulder belt across mid-chest and
shoulder)?
• Is the child able to use the properly ad- justed head restraint/headrest?
• Will the child be able to stay in position for the entire ride?
1-22Safety-Seats, seat belts and supplemental restraint system

–Infants and children should never
be held on anyone's lap. Even the
strongest adult cannot resist the
forces of a collision.
– Do not put a seat belt around both
a child and another passenger. –
NISSAN recommends that all child
restraints be installed in the rear
seat. Studies show that children
are safer when properly re-
strained in the rear seat than in
the front seat. If you must install a
forward-facing child restraint in
the front seat, refer to “Forward-
facing child restraint installation
using the seat belts” in this
section.
– Even with the NISSAN Advanced
Air Bag System, never install a
rear-facing child restraint in the
front seat. An inflating air bag
could seriously injure or kill a child.
A rear-facing child restraint must
only be used in the rear seat.
– Be sure to purchase a child re-
straint that will fit the child and
vehicle. Some child restraints may
not fit properly in your vehicle.
– Child restraint anchorages are de-
signed to withstand only those
loads imposed by correctly fitted
child restraints. Under no circum-
stances are they to be used to at-
tach 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 in-
stalled using the damaged an-
chorage, and a child could be
seriously injured or killed in a
collision.
– Never use the anchor points for
adult seat belts, or other items.
– A child restraint with a top tether
strap should not be used in the
front passenger seat.
– Keep seatbacks as upright as pos-
sible af ter fitting the child
restraint.
– Infants and children should al-
ways be placed in an appropriate
child restraint while in the vehicle.
• When the child restraint is not in use,
keep it secured with the LATCH sys-
tem or a seat belt. In a sudden stop or
collision, loose objects can injure oc-
cupants or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating
surface and buckles before placing a
child in the child restraint.
WRS0256
1-24Safety-Seats, seat belts and supplemental restraint system

This vehicle is equipped with a universal
child restraint anchor system, referred to
as the LATCH (Lower Anchors and Tethers
for CHildren) system. Some child restraints
include rigid or webbing-mounted attach-
ments that can be connected to these an-
chors. For additional information, refer to
“LATCH (Lower Anchors and Tethers for
CHildren) system” in this section.
If you do not have a LATCH compatible
child restraint, the vehicle seat belts can be
used.
Several manufacturers offer child re-
straints for infants and children of various
sizes. When selecting any child restraint,
keep the following points in mind:
• Choose only a restraint with a label certi-f ying that it complies with Federal Motor
Vehicle Safety Standard 213 or Canadian
Motor Vehicle Safety Standard 213.
• Check the child restraint in your vehicle to be sure it is compatible with the vehicle's
seat and seat belt system. • If the child restraint is compatible with
your vehicle, place your child in the child
restraint and check the various adjust-
ments to be sure the child restraint is
compatible with your child. Choose a
child restraint that is designed for your
child's height and weight. Always follow
all recommended procedures.
• If the combined weight of the child and child restraint is less than 65 lbs. (29.5 kg),
you may use either the LATCH anchors or
the seat belt to install the child restraint
(not both at the same time).
• If the combined weight of the child and child restraint is greater than 65 lbs. (29.5
kg), use the vehicle’s seat belt (not the
lower anchors) to install the child re-
straint.
• Be sure to follow the child restraint manufacturer’s instructions for installa-
tion.
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. Canadian law re-
quires the top tether strap on forward-
facing child restraints be secured to the
designated anchor point on the vehicle.
LATCH (Lower Anchors and
Tethers for CHildren) SYSTEM
Your vehicle is equipped with special an-
chor points that are used with LATCH sys-
tem compatible child restraints. This sys-
tem may also be referred to as the ISOFIX
or ISOFIX compatible system. With this sys-
tem, you do not have to use a vehicle seat
belt to secure the child restraint unless the
combined weight of the child and child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and child restraint
is greater than 65 lbs. (29.5 kg) use the vehi-
cle’s seat belt (not the lower anchors) to
