2021 NISSAN MAXIMA fuel pressure

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing 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 ve-
hicle from moving. Move the shif t le-
ver to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing 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 working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle. •
Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warn-
ing, 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 en-
closed 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 nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• On gasoline engine models, the fuel
filter or fuel lines should be serviced.
It is recommended that you visit a
NISSAN dealer for this service be-
cause the fuel lines are under high
pressure even when the engine is off.
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 fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-22).
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
