WARNING
Automotive fuel 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 Fuel Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use mobile phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire. •
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup 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
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other fuel 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.
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 fuel.
• When refueling, always shift the
gear to the P (Park) position, set
the parking brake, and press the
Engine Start/Stop button to the
OFF position. 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 fuel
spillage.
