Fuel System Leak
{
Warning
If you smell a persistent natural
gas odor or hear a continual
hissing sound, there could be a
natural gas leak. If the natural gas
is ignited, you or others could be
injured. Do not start the engine or
drive the vehicle. Have the
vehicle towed to an authorized
GM dealer for service.
A slight natural gas odor may be
detected for a few moments after
refueling. This is normal. You should
not be able to smell natural gas at
any other time. If you do, or if you
hear a hissing sound, the fuel
system may have a leak.
If natural gas is smelled or a hissing
sound is heard:
1. Park the vehicle in a
well-ventilated area and apply
the parking brake. Keep heat,
sparks, and flame away. Open
all the vehicle doors for
ventilation.
2. Turn the ignition to LOCK/OFF.
