child lock NISSAN ALTIMA 2021 Owners Manual

WARNING
∙ Do not ride in a moving vehicle whenthe 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 information,
refer to “Precautions on seat belt us-
age” 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 se-
rious 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.

∙ Do not allow children to play with theseat 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 acti-
vated, the child can be seriously in-
jured or killed if the seat belt retracts
and becomes tight. This can occur
even if the vehicle is parked. Unbuckle
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.
Fastening the seat belts
1. Adjust the seat. For additional informa- tion, refer to “Seats” in this section.

3. Position the lap belt portionlow and
snug on the hips
Bas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
C.
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
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, re-
lease 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.

∙ To help avoid risk of injury or deaththrough unintended operation of the
vehicle and/or its systems, including
entrapment in windows and/or inad-
vertent door lock activation, do not
leave children, people who require the
assistance of others and/or pets un-
attended 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.
LOCKING WITH KEY
To lock the door using the mechanical key,
turn the key toward the rear of the vehicle
1. This will only lock the corresponding
door and will not activate the security sys-
tem. To arm the security system, press
the

CHILD SAFETY REAR DOOR LOCK
Child safety locks help prevent the rear
doors from being opened accidentally, es-
pecially when small children are in the ve-
hicle.
The child safety lock levers are located on
the edge of the rear doors.
When the lever is in the unlock position
2,
the door can be opened from the outside
or the inside.
When the lever is in the LOCK position
1,
the door can be opened only from the
outside.

WARNING
∙ Never allow anyone to ride in thecargo 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 sliding
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 po-
sition. If they are not completely se-
cured, 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 seriously
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.
OPENER OPERATION
The fuel-filler door release is located below
the instrument panel. To open the fuel-filler
door, pull the release. To lock, close the fuel-
filler door securely.
FUEL-FILLER CAP

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
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.
