2023 INFINITI QX50 warning

The illustration shows the location of the
floor mat retainer clips.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely in
the shade before using them. For additional
information, see “Seat belt maintenance”
(P. 1-19).
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely weaken
the seat belt webbing.
CLEANING THE SEAT TRACKS
CAUTION
Periodically clean the seat tracks to pre-
vent reduction of ability to move the seats.
Clean periodically with a high-powered
vacuum cleaner. Dirt and debris may reduce
the ability to adjust the seat. A wet cleansing
agent may be used if necessary.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
• The accumulation of moisture-retaining dirt and debris in body panel sections, cavi-
ties, and other areas.
• Damage to paint and other protective coatings caused by gravel and stone chips
or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry completely
inside the vehicle and should be removed for
drying to avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas
where the temperatures stay above freezing
and where atmospheric pollution exists and
road salt is used.

CORROSION PROTECTION
Appearance and care7-7

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
• Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle. •
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
• Never get under the vehicle while it is
supported only by a jack. If it is necessary
to work under the vehicle, support it
with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
• Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
• Never leave the engine or Continuously
Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.

8. Engine oil filler cap
9. Engine oil dipstick
NOTE:
Your vehicle may not be equipped with
an engine cover.
The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
WARNING
• Never remove the coolant reservoir cap
when the engine is hot. Wait until the
engine and radiator cool down. Serious
burns could be caused by high pressure
fluid escaping from the radiator. For ad-
ditional information on precautions, see
“If your vehicle overheats” (P. 6-7).
• The coolant reservoir is equipped with a
pressure type coolant reservoir cap. To
prevent engine damage, use only a
Genuine NISSAN coolant reservoir cap.
CAUTION
• Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
• When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C). If additional freeze protection
is needed due to weather where you op-
erate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
concentrate following the directions on
the container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s instruc-
tions to maintain minimum antifreeze
protection to -34° F (-37° C). The use of
other types of coolant solutions other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system.
