WARNING
cGasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
cFuel may be under pressure. Turn the
cap a third of a turn, and wait for any
“hissing” sound to stop to prevent fuel
from spraying out and possibly causing
personal injury. Then remove the cap.
cDo not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
cUse 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 emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
cNever pour fuel into the throttle body to
attempt to start your vehicle.cDo 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 fill-
ing it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.cTighten until the fuel-filler cap clicks.
Failure to tighten the fuel-filler cap
properly may cause the
mal-
function indicator light (MIL) to illumi-
nate. If the
light illuminates be-
cause the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle.
The
light should turn off after a
few driving trips. If the
light
does not turn off after a few driving
trips, have the vehicle inspected by a
NISSAN dealer.
cFor additional information, see the
“Malfunction indicator light (MIL)” in
the “Instruments and Controls” section
earlier in this manual.
