CAUTION:
{
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. 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 overfill
the tank and wait a few seconds after you have
finished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. See Washing Your Vehicle on page 442.
When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap
has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere.
See Malfunction Indicator Lamp on page 190.
Your vehicle may also have a check gas cap
warning light, which will be displayed on the
instrument panel cluster if the fuel cap is not
properly installed. See Check Gas Cap Light
on page 199 for more information.
If your vehicle has a Driver Information Center
(DIC), the CHECK GAS CAP message will
be displayed if the fuel cap is not properly
installed. See DIC Warnings and Messages
on page 208 for more information.
CAUTION:
{
If a fire starts while you are refueling,
do not remove the nozzle. Shut off the
flow of fuel by shutting off the pump or
by notifying the station attendant. Leave
the area immediately.
Notice: If you need a new fuel cap, be sure to
get the right type. Your dealer can get one for
you. If you get the wrong type, it may not fit
properly. This may cause your malfunction
indicator lamp to light and may damage
your fuel tank and emissions system. See
Malfunction Indicator Lamp on page 190.
