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 your
tank and wait a few seconds after you have finished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. See Cleaning
the Outside of Your Vehicle on page 5-94.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. 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 3-48.
If your vehicle has the optional Driver Information
Center (DIC), the CHECK GAS CAP message will be
displayed if the fuel cap is not properly reinstalled.
