& WARNING Risk of fire or explosion from
electrostatic charge
Electrostatic charge can create sparks and
thereby ignite fuel vapors.
Before you open the fuel filler cap or

take hold of the pump nozzle, touch the
metallic vehicle body.
This discharges any electrostatic charge
that may have built up.
Do not get into the vehicle again during
#
the refueling process.
Otherwise, electrostatic charge could
build up again.
