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 369.
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 174.
In addition, the CHECK GAS CAP message will
be displayed in the Message Center if the fuel cap
is not properly reinstalled. See Check Gas Cap
Message on page 185 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 retailer 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.
