refueling. Do not smoke if you are near fuel
or refueling your vehicle. Do not use

smoking materials away from fuel. Do not
leave the fuel pump unattended when

{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.

possible. SeeWashing Your Vehicle on page 495.
When replacing the fuel cap, turn it clockwise until

cap has been left off or improperly installed.
This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp
on page 212.There may also be a light that comes on in the
instrument panel to let you know if your gas cap
is not properly installed. SeeCheck Gas Cap Light
on page 219for more information.
