(Continued)
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
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.(Continued)
(Continued)Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
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.
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage. (Continued)
Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.(Continued)
