length NISSAN ALTIMA 2023 Owners Manual

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.

WARNING
• Do not leave children or adults who
would 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 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.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
