WARNING - Refueling
• If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
• Do not "top off" after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

(Continued)
• Do not get back into a vehicle
once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
• When using an approved
portable fuel container, be sure to
place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling has
begun, contact with the vehicle
should be maintained until the
filling is complete.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
• Read and follow all warning at the
gas station facility.
• Before refueling note the location
of the Emergency Gasoline Shut-
Off, if available, at the gas station
facility.
• Before touching the fuel nozzle,
you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.
(Continued)
(Continued)
Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
• When refueling, always shut the
engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
• DO NOT use matches or a lighter
and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
