Chevrolet 2006 Epica Owner's Manual page 233

The tethered fuel cap is located behind a hinged fuel
door on the passenger's side of the vehicle. To remove
the fuel cap, turn it slowly to the left (counterclockwise).
While refueling, hang the tethered cap inside the
fuel door.
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 5-70.
