length INFINITI QX55 2023 Owners Manual

Seat belt hook
When the seat belt is not in use and when
folding down the rear seats, hook the rear
seat belts on the seat belt hooks.
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 compat-
ible with the installed seat belts is available
for purchase. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for the driver and front passenger seat-
ing positions.It is recommended that you visit an INFINITI
retailer for assistance with purchasing an ex-
tender if an extender is required.
WARNING
• Only INFINITI seat belt extenders, made
by the same company which made the
original equipment seat belts, should be
used with INFINITI seat belts.
• Adults and children who can use the
standard seat belt should not use an ex-
tender. Such unnecessary use could re-
sult 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 com-
pletely 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 buck-
les, tongues, retractors, flexible wires and
anchors, work properly. If loose parts, de-
terioration, cuts or other damage on the
webbing is found, the entire seat belt as-
sembly should be replaced.

WARNING
• Do not leave children or adults who
would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acci-
dentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days, tem-
peratures in a closed vehicle could
quickly become high enough to cause se-
vere or possibly fatal injuries to people or
animals.
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they con-
tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death. •
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle in-
spected immediately.
• Do not run the engine in closed spaces
such as a garage.
• Do not park the vehicle with the engine
running for any extended length of time.
• Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
• If electrical wiring or other cable connec-
tions must pass to a trailer through the
seal on the liftgate 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 when-
ever:
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 involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust 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 ex-
haust system components.
• Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
