GMC 2008 Canyon - Manual (Page 269)

{ CAUTION:
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 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 5-103.
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. If the fuel cap is not properly
installed, the FUEL CAP message will appear on the
Driver Information Center (DIC) and the check engine
light will be lit on the instrument panel cluster. See DIC
Warnings and Messages on page 3-42 and Malfunction
Indicator Lamp on page 3-34 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 dealer/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. See Malfunction Indicator Lamp
on page 3-34.
