2020 NISSAN ALTIMA fuel pressure

∙ Your vehicle will reach its ideal oper-ating temperature more quickly
while driving versus idling.
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual. If any malfunction occurs in the AWD sys-
tem while the engine is running, messages
are displayed in the meter.

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, ap-ply 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 key 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 jew-
elry, such as rings, watches, etc. be-
fore working 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 key is in the OFF position and the
engine is not running. To avoid injury, al-
ways 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 neces-
sary to work under the vehicle, sup-
port 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 because
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. Al-
ways conform to local 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 component
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, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
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.

FUEL RECOMMENDATION:
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION
∙ Only vehicles with the E-85 filler doorlabel can operate on E-85. Fuel system
or other damage can occur if E-85 is
used in vehicles that are not designed
to run on E-85.
∙ Using a fuel other than that specified could adversely affect the emission
control system, and may also affect
the warranty coverage.
∙ Under no circumstances should a leaded gasoline be used, because this
will damage the three-way catalyst. ∙ Do not use a fuel containing more
than 15% ethanol in your vehicle. Your
vehicle is not designed to run on a fuel
containing more than 15% ethanol.
Using a fuel containing more than 15%
ethanol in a vehicle not specifically
designed for a fuel containing more
than 15% ethanol can adversely affect
the emission control devices and sys-
tems of the vehicle. Damage caused
by such fuel is not covered by the
NISSAN New Vehicle Limited Warranty.
∙ Do not use fuel that contains the oc- tane booster methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated gasoline. ∙ U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percentage
for that region.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
ENGINE OIL RECOMMENDATION:
Refer to “Recommended fluids/lubricants
and capacities” in the “Technical and con-
sumer information” section of this manual.
COLD TIRE PRESSURE:
For additional information, refer to “Tire and
Loading Information label” in the “Technical
and consumer information” section of this
manual.
The label is typically located on the driver
side center pillar or on the driver’s door. For
additional information, refer to “Wheels and
tires” in the “Do-it-yourself ” section of this
manual.
