gas type NISSAN FRONTIER 2021 Owners Manual

•Do not attempt to top off the fuel
tank af ter the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire.
• Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle.
• Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices
when filling. –
Keep the pump nozzle in contact
with the container while you are
filling it.
– Use only approved portable fuel
containers for flammable liquid.
CAUTION
• Do not use a fuel containing more
than 15% ethanol in your vehicle. For
additional information, refer to “Fuel
recommendation” in the “Technical
and consumer information” section
of this manual.
• The LOOSE FUEL CAP warning will ap-
pear if the fuel-filler cap is not prop-
erly tightened. It may take a few driv-
ing trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly af ter the LOOSE
FUEL CAP warning appears may
cause the
Malfunction Indicator
Light (MIL) to illuminate. •
Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illu-
minate. If the
light illuminates
because the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few
driving trips. If thelight does not
turn off af ter a few driving trips, have
your vehicle inspected. It is recom-
mended that you visit a NISSAN
dealer for this service.
• For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” sec-
tion in this manual.
• If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.
