Fuel Gauge
When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the vehicle fuel tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on. The fuel gauge has been calibrated
to display full at approximately
24 800 kPa (3,600 psig) and empty
at approximately 2 758 kPa
(400 psig).
When the low fuel warning indicator
flashes, fill the tank as soon as
possible.
Compressed Natural Gas (CNG)
fuel gauge readings are affected by
changes in fuel temperature and
fuel pressure.

Warning (Continued)
.Keep all smoking materials
and sources of ignition away
from the fuel system
components.
. CNG is non-toxic but the
vapors are lighter than air
and can cause oxygen
depletion if they are
enclosed in a confined
space. Make sure there is
adequate ventilation and
use extreme caution if a
leak is suspected.
{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 an outdoor open 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.
