GMC 2004 Canyon - Manual (Page 273)

{ 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.
{ 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.
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 5-98
Cleaning the Outside of Your Vehicle. When filling
the tank do not overfill by squeezing in much more fuel
after the pump shuts off.
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. If the fuel cap is not properly installed,
FUEL CAP will appear on the DIC and the check engine
light will be lit on instrument panel cluster. See DIC
Warnings and Messages on page 3-39 and Malfunction
Indicator Lamp on page 3-30 for more information.
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 3-30.
