While refueling, hang the tethered fuel cap from the
hook on the fuel door.
{ WARNING:
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 the 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 6‑109.
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 4‑62.
The CHECK GAS CAP message will appear on the
Driver Information Center (DIC) display if the fuel cap is
not reinstalled properly. See DIC Warnings and
Messages on page 4‑76 for more information.
