2017 NISSAN ALTIMA SEDAN ECU

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 install
child restraints. If the child restraint 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 recom-
mended 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 shoulder
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 damage on the
webbing is found, the entire seat belt as-
sembly should be replaced.
WARNING
Do not allow children to play with the seat
belts. Most seating positions are
equipped with Automatic Locking Retrac-
tor (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. Un-
buckle the seat belt to release 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, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child.
CHILD SAFETY
Safety—Seats, seat belts and supplemental restraint system1-19

There are three basic types of child restraint
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 children who outgrow rear-
facing child restraints 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 protec-
tion. 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 improperly fitting seat
belt could cause serious or fatal injury.
Always use appropriate child restraints. All U.S. states and Canadian provinces or territo-
ries require the use of approved child restraints
for infants and small children. For additional infor-
mation, refer to “Child restraints” in this section.
A child restraint may be secured in the vehicle by
using either the LATCH (Lower Anchors 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 restraint sys-
tem (air bag system) for the front passen-
ger. For additional information, refer to
“Supplemental Restraint System (SRS)” in
this section.
INFANTS
Infants up to at least 1 year old should be placed
in a rear-facing child restraint. NISSAN recom-
mends 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.
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 restraint. 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 re-
straint with a harness. Refer to the manufactur-
er’s instructions for minimum and maximum
weight and height recommendations. NISSAN
recommends that small children be placed in
child restraints that comply with Federal Motor
Vehicle Safety Standards or Canadian Motor Ve-
hicle Safety Standards. You should choose a
child restraint that fits your vehicle and always
follow the manufacturer’s instructions for instal-
lation and use.
LARGER CHILDREN
Children should remain in a forward-facing child
restraint with a harness until they reach the maxi-
mum height or weight limit allowed by the child
restraint manufacturer.
1-20Safety—Seats, seat belts and supplemental restraint system

– NISSAN recommends that all childrestraints be installed in the rear
seat. Studies show that children are
safer when properly restrained 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 in-
stallation 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 restraint 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 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 using the damaged anchor-
age, and a child could be seriously
injured or killed in a collision.
– Never use the anchor points for adult seat belts or harnesses.
– A child restraint with a top tether strap should not be used in the front
passenger seat.
– Keep seatbacks as upright as pos- sible after fitting the child restraint.
– Infants and children should always be placed in an appropriate child re-
straint while in the vehicle.
● When the child restraint is not in use,
keep it secured with the LATCH system
or a seat belt. In a sudden stop or colli-
sion, loose objects can injure occupants
or damage the vehicle.CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating sur-
face and buckles before placing a child in
the child restraint.
This vehicle is equipped with a universal child
restraint anchor system, referred to as the LATCH
(Lower Anchors and Tethers for CHildren) sys-
tem. Some child restraints include rigid or
webbing-mounted attachments that can be con-
nected to these anchors. For additional informa-
tion, refer to “LATCH (Lower Anchors and Teth-
ers 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 restraints for
infants and children of various sizes. When se-
lecting any child restraint, keep the following
points in mind: ● Choose only a restraint with a label certifying
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.
Safety—Seats, seat belts and supplemental restraint system1-23

●If the child restraint is compatible with your
vehicle, place your child in the child restraint
and check the various adjustments 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 an-
chors) to install the child restraint.
● Be sure to follow the child restraint manufac-
turer’s instructions for installation.
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 vehicle is
being operated. Canadian law requires the
top tether strap on forward-facing child re-
straints be secured to the designated an-
chor point on the vehicle.
LATCH (Lower Anchors and Tethers
for CHildren) SYSTEM
Your vehicle is equipped with special anchor
points that are used with LATCH system compat-
ible child restraints. This system may also be
referred to as the ISOFIX or ISOFIX compatible
system. With this system, you do not have to use
a vehicle seat belt to secure the child restraint
unless the combined weight of the child and child
restraint 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 vehicle’s
seat belt (not the lower anchors) to install the child restraint. Be sure to follow the child restraint
manufacturer’s instructions for installation.
The LATCH anchor points are provided to install
child restraints in the rear outboard seating posi-
tions only. Do not attempt to install a child re-
straint in the center position using the LATCH
anchors.

WARNING
Failure to follow the warnings and instruc-
tions for proper use and installation of
child restraints could result in serious in-
jury or death of a child or other passen-
gers in a sudden stop or collision:
– Attach LATCH system compatible child restraints only at the locations
shown in the illustration.
– Do not secure a child restraint in the center rear seating position using the
LATCH lower anchors. The child re-
straint will not be secured properly.

– Inspect the lower anchors by insert-ing your fingers into the lower anchor
area. Feel to make sure there are no
obstructions over the anchors such
as seat belt webbing or seat cushion
material. The child restraint will not
be secured properly if the lower an-
chors are obstructed.
– 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 restraint will not be properly
installed using the damaged anchor-
age, and a child could be seriously
injured or killed in a collision.
LATCH lower anchor location
The LATCH anchors are located as shown. A
label is attached to the seatback to help you
locate the LATCH lower anchors.
Installing child restraint LATCH lower
anchor attachments
LATCH compatible child restraints include two
rigid or webbing-mounted attachments that can
be connected to two anchors located at certain
seating positions in your vehicle. With this sys-
tem, you do not have to use a vehicle seat belt to
secure the child restraint. Check your child re-
straint for a label stating that it is compatible with
LATCH. This information may also be in the in-
structions provided by the child restraint manu-
facturer.

Do not use the lower anchors if the combined
weight of the child and the child restraint exceeds
65 lbs (29.5 kg) . If the combined weight of the
child and the child restraint is greater than 65 lbs
(29.5 kg) , use the vehicle’s seat belt (not the
lower anchors) to install the child restraint. Be
sure to follow the child restraint manufacturer’s
instructions for installation.
Follow these steps to install a rear-facing child
restraint using the LATCH system:1. Position the child restraint on the seat. Al- ways follow the child restraint manufactur-
er’s instructions.
2. Secure the child restraint anchor attach-ments to the LATCH lower anchors. Check
to make sure the LATCH attachment is prop-
erly attached to the lower anchors.

3. For child restraints that are equipped withwebbing-mounted attachments, remove any
additional slack from the anchor attach-
ments. Press downward and rearward firmly
in the center of the child restraint with your
hand to compress the vehicle seat cushion
and seatback while tightening the webbing
of the anchor attachments. 4. After attaching the child restraint, test it be-
fore you place the child in it. Push it from side
to side while holding the child restraint near
the LATCH attachment path. The child re-
straint should not move more than 1 inch
(25 mm) , from side to side. Try to tug it
forward and check to see if the LATCH at-
tachment holds the restraint in place. If the
restraint is not secure, tighten the LATCH
attachment as necessary, or put the restraint
in another seat and test it again. You may
need to try a different child restraint or try
installing by using the vehicle seat belt (if
applicable) . Not all child restraints fit in all
types of vehicles. 5. Check to make sure the child restraint is
properly secured prior to each use. If the
child restraint is loose, repeat steps 1
through 4.
