Cadillac 2006 XLR - Manual (Page 325)

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 6-74.
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 3-58.
The CHECK GAS CAP message in the Driver
Information Center (DIC) will be displayed if the
fuel cap is not properly installed.
{ 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 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 3-58.
